  • Barriers or dividers of various types have been installed for isolating passengers in the rear seat of a motor vehicle.
  • barriers suitable for children traveling in a family vehicle may require some measure of physical and visual isolation, but are subject to quite different requirements than are normally considered as useful for transporting prisoners, for example, or for traveling with domesticated animals.

At the same time, such a divider should not obstruct visibility for the driver. Adult passengers in the front seat may still need access to the children during travel, which also sets some dimensional constraints.
  • Construction materials for the divider should be suitably chosen considering factors such as how the material(s) would respond under collision impact, how well the material(s) hold the divider shape, material flammability, material durability, cleanability of surfaces, and other factors. Other practical considerations can include flotation ability of the materials.
  • the material(s) used would preferably be compliant, compressible, and resilient, so that it does not compromise child safety or obstruct desired access or passage. There should be sufficient stiffness for holding its shape, without being overly rigid.
  • divider device can include making the divider device more compact, such as for shipping and storage, minimizing or eliminating number of parts, particularly small parts with the potential of causing a choking hazard, use of recyclable materials, durability of surfaces to staining, soiling, and ultraviolet light exposure, and so on.
  • the device shown falls short of what is needed for adaptability (ii, above) since it is designed for a particular configuration of automobile seats.
  • the Passehl '487 device also fails to satisfy accessibility criteria given in (i) above, since it must be moved out of place in order to allow child access across the middle of the car in loading or unloading.

  • FIGS 1 A and IB are perspective and front views, respectively, of a rear seat divider 10 in position in a motor vehicle according to one embodiment.
  • Seat divider 10 fits into the middle seat space in the rear seat of an automobile or other type of motor vehicle and is held in place by a lap restraint belt 12 and a shoulder restraint belt 14 for that seat position. With restraint belts 12 and 14 engaged, seat divider 10 is

  • Pliable covering 74 may be formed from any of a number of suitable types of materials, including cotton, wool, fleece, suede, leather, plastic, rubber, vinyl, neoprene, urethane/polyurethane, polyester, polyethylene, nylon, microsuede, or various other types of natural or synthetic fabrics, for example.
  • Pliable covering 74 may be stitched, molded, glued, ultrasonically or thermally welded, or otherwise formed and then applied over a foam or other core material or may be inflatable.
  • Pliable covering 74 may be attached to a core material, such as using a zipper or other fastener, including a loop and hook type fastener, for example.
  • pliable covering 74 is formed by a coating or skinning process that applies a material onto a foam or other core, forming a skin over the core material.
  • the skin that serves as pliable covering 74 is formed of the core material itself via an in-mold processing that gives a surface of a material a more robust structure.
  • pliable covering 74 is itself inflatable, formed, for example, from a rubber or rubberized or rubber-lined or -coated material, such as a rubber-reinforced textile, or formed from a plastic, PVC, urethane/polyurethane, polyester, polyethylene, neoprene or other synthetic material or coated material that is capable of being configured to provide an air-tight bladder.
  • a suitable material for inflatability may include an inner rubberized lining of a textile for providing an air-tight bladder coupled with an outer fabric that provides an alternate texture or appearance, for example.

  • rear seat divider 10 is a low-profile device and is dimensioned so that it does not obstruct driver visibility out the rear window of the motor vehicle. Because its forward extension is typically no further than the front edge of the rear seat, as shown in Figure 1A, for example, rear seat divider 10 allows passage across the middle of the vehicle for children climbing into or out of their seats on either the passenger or driver side.
  • the height of seat divider 10 is no more than about 3 inches higher than the height of the backrest for a standard motor vehicle, preferably no higher than the height of the backrest or even shorter than this height.
  • a typical height dimension is about 20-24 inches in one embodiment, tall enough to provide a visual divider for child occupants of the rear seat, but short enough so as not to obstruct driver rear-view visibility.
  • the depth of the seat divider extends forward to no more than about 3 inches beyond the edge of seat bottom surface 80, preferably within no more than about 1 inch longer than the front edge of the rear seat, more preferably not extending forward as far as the edge of the rear seat.
  • a typical depth dimension for the base of divider 10 in one embodiment of the present invention (with depth being in the direction from the front surface of the rear seat to the backrest) is about 14-18 inches.
  • the width of divider 10 is about 6 inches in one embodiment, but can be thicker or thinner that this value based on materials such as the material used to form the device, for example.
  • Figures 3A and 3B show side views of the rear seat divider with lap and shoulder restraint belts fastened, in an embodiment using separate slots for each restraint belt. In the embodiment shown, a lap restraint belt slot 20 is cut inward from the front surface of rear seat divider 10.
  • a shoulder restraint belt slot 22 is a slot cut inward from the top surface in this embodiment.
  • Figures 3C and 3D show side views of the rear seat divider with lap and shoulder restraint belts fastened, in an embodiment using a single slot 44 for both restraint belts.
  • slot 44 is preferably long enough on one side of divider 10 (Figure 3D) to accommodate insertion of both lap and shoulder restraint belts 12 and 14, but may be shorter on the other side ( Figure 3C) to accommodate lap and shoulder restraining belt exit.
  • slot 44 could be made equally long on both sides, this tapered design and small exit hole size can be effective deterrents for children who may be inclined to try to stick their hands through the slot, such as to reach the child on the opposite side.
  • Materials Rear seat divider 10 can be formed from a block 76 that is compressible and has a shape memory.
  • Block 76 can be in the form of an inflatable bladder, for example, or formed from any of a number of compressible core materials.
  • One property of particular interest relates to resiliency, that is, the ability of the material to spring back to its original shape after being compressed for some period of time. In the context of the present disclosure, a material having this property of resiliency or shape recovery is considered to have "shape memory".
  • Materials that have shape memory include an inflatable bladder as well as various types of resilient foam materials such as various types of closed- or open-cell polyurethane, ethylene vinyl acetate (also known as EVA), polyolefm elastomer (also known as POE), CrosliteTM (a foam material proprietary to Crocs, Inc.), for example, that can be compressed and, when the compressive force is released, substantially recover their original shape.
  • Compressible, resilient foam materials are compliant to surrounding surfaces when compressed and are able to return to their original shape when the compressive force is removed.
  • Compressible foam materials are rated according to various performance factors, including their Indentation Force Deflection (IFD), which indicates the amount of force needed to indent up to 25% of its thickness a 4-inch-thick sample of foam. Density, typically given in pounds per cubic foot, is another factor that is used to rate such materials. It should be noted that embodiments of the present invention for a compressible block do not require highly dense materials or materials over a given IFD range.
  • IFD Indentation Force Deflection
  • the compressive forces that are applied to the rear seat divider are in the moderate range applied from lap and shoulder restraint and other types of restraint devices.
  • Higher density materials are advantaged for overall durability.
  • Lower density materials are advantaged for minimizing rear seat divider weight and cost.
  • Higher IFD materials are advantaged for providing a level of firmness or overall integrity to the rear seat divider.
  • Suitable viable materials that can be used to provide a block of core material for rear seat divider 10 include, for example, molded, closed-cell or open-cell self-skinning foams. These have the advantage of improved resistance to fluids, bacteria, mold, etc.
  • Frictional contact for enhancing the frictional grip between the rear seat divider and typical automobile seat and restraint belt materials is advantageous in order to discourage slippage or sliding along the plane, arc, or general area of surface contact, and to generally aid in stabilizing the rear seat divider in the automobile.
  • one or more of the rear or base contact surfaces or the belt interface surfaces of divider 10 can comprise an optional material for enhanced friction, such as a material taken from the group consisting of a polyurethane foam material, fleece, felt, flannel, cotton, rubber, silicone, polymer, suede, microsuede, and leather.
  • One or more of the contact surfaces can comprise a "non-slip" material and/or structure specifically engineered to have enhanced frictional grip in combination with other materials.
  • Figure 4A shows a side view of the rear seat divider formed from a block 76 that is compressible and has a shape memory.
  • block 76 is formed from a compressive, resilient core material with shape memory and having curvilinear, e.g., arcuate, slots 20 and 22 for their corresponding restraint belts.
  • the relative direction of arcuate slots 20 and 22 is shown, with approximate arc centers B 1 and B2 as indicated. While not the only workable slot arrangement for the rear seat divider, this particular open slot orientation has been found to be advantageous for ease of installing seat restraint belts and for providing the needed frictional grip and compressive forces for holding the divider securely in position against the seat bottom and backrest, as described in more detail subsequently.
  • the slots 20 and 22 can be formed by a variety of curvilinear shapes for receiving the restraint belts 14 and 20, including various hook shapes including "J" shapes, for entrapping the restraint belts 14 and 20 within the block 76 and for engaging the block 76 with compressive forces that urge the block76 against the seat bottom surface 80 and the backrest 82.
  • a curved portion of the slots 20 and 22 is particularly effective for entrapping the lap and shoulder restraint belts 14 and 20 in position within the block 76 while a remaining portion of the slots 20 and 22, which can be a straight portion, is particularly effective for applying the compressive forces to the block 76 in a direction that compresses the block 76 between the lap and shoulder restraint belts 14 and 20 and the seat bottom and backrest surfaces 80 and 82.
  • Figure 4B is a partial cross-sectional view of slot 22 showing an interface surface 78 for providing frictional contact against shoulder restraint belt 14.
  • interface surface 78 may be untreated, since the compressible foam provides sufficient frictional grip against the surface of shoulder restraint belt 14.
  • a similar interface arrangement can be used for slot 20.
  • interface surface 78 can be treated, such as by application of a coating that provides additional friction, for example.
  • An optional clip 26, such as a plastic clip that is coupled to seat divider 10, can also be provided on either or both sides of the slot for increased grip against the restraint belt.
  • the belt contact surface at each belt interface should provide frictional contact with the belt at a level that is sufficient to discourage slippage of the belt against the contact surface.
  • One or more of the rear or base or belt contact surfaces can comprise a material taken from the group consisting of a polyurethane foam material, fleece, felt, flannel, cotton, rubber, silicone, polymer, suede, microsuede, and leather.
  • One or more of the contact surfaces can comprise a "non-slip" material and/or structure specifically engineered to have enhanced friction in combination with other materials.
  • non-slip materials examples include, but are not limited to ECO PER® Non Slip Fabric from PracticalSurfaceWare, Buckinghamshire, UK; Jiffy Grip brand traction material or Slipper Grippers, both available from JoAnn Stores, Inc., Hudson, OH; and Lattice Non Slip Fabric and Mesh Lattice Non Slip Fabric from
  • NonSlip Tapes LLC East Butler, PA.
  • one or more of the contact surfaces can have its friction enhanced by the addition of "non-slip” patches such as, for example, “GRiPPiES No-Slip Adhesive Shapes," from GRiPPiES, LLC of Long Island, NY, or by the addition of "non-slip” tape such as, for example, Anti Slip Grip Tape from NonSlip Tapes LLC, East Butler, PA.
  • seat divider 10 is provided as an inflatable device having a nozzle 56, shown in enlarged form.
  • pliable covering 74 is formed to provide an inflatable bladder 60 of air, shown in dashed line form in Figure 5. This forms block 76 so that it is compressible and also has shape memory, so that it recovers its shape when not compressed. Slots 20 and 22, formed by the pattern of inflatable pliable covering 74, extend through block 76 for accepting the appropriate restraint belts.
  • an inflatable version has advantages for packaging, shipping, and storage of rear seat divider 10, since it allows inflation at any time and also permits deflation when not in use. Some portion or all of divider 10 can be made inflatable.
  • An internal air bladder 60 that is separate from and lies within pliable covering 74 can be provided, for example, so that an adult can adjust the stiffness of divider 10 to a suitable setting.
  • interface surfaces for contact against the restraint belt or motor vehicle seat can use a material that provides a frictive contact with enhanced frictional grip, such as those described previously.
  • pliable covering 74 may be provided over some or all surfaces of block 76, depending on whether an inflatable or foam core design is used. This allows relatively high coefficients of friction to be obtained, regardless of bulk material construction of inner portions of the divider, with appropriate choice of pliable coverings such as, for example, fleece, flannel, felt, cotton, rubber, silicone, polymer, suede, microsuede, or leather materials or other non-slip materials previously described. Additionally, the belt, back, or base contact areas of the cover may comprise different materials than the other sections of the pliable covering (e.g., rubber for the contact areas and fleece for the non-contact areas).
  • the contact areas of the divider provide sufficient frictional contact to discourage slippage or sliding contact, both against restraining belt fabric, which is typically a synthetic material, and against materials conventionally used for automobile seat components.
  • Frictional contact against the seat material of the rear seat and against lap and shoulder restraining belts helps to stabilize seat divider 10.
  • the frictional contact helps to constrain twisting, tipping/tilting, lateral movement, or other unwanted shifting or other motion of rear seat divider 10.
  • stiffness over at least a portion of divider 10 is reduced, allowing the seated child to cling to the rear seat divider as a toy.
  • the rear seat divider may be removed and function as a toy outside of the vehicle as well. Referring back to Figures 3A-3D, whichever slot arrangement is used, the slot orientation allows the rear and back surfaces of rear seat divider 10 to be compressively held against the bottom surface of the rear seat and against the backrest.
  • FIG. 6 A shows the compressive force that is applied by lap restraint belt 12 according to an embodiment of the present invention.
  • Lap restraint belt 12 when inserted through slot 20 and engaged, provides an urging force Fl, a component of which compressively urges at least a portion of a base contact surface 52 of the divider against seat bottom surface 80 of the motor vehicle. Similarly, a component of this compressive force also urges the divider against the backrest 82.
  • urging force Fl can be considered to urge divider 10 toward the intersection of the bottom surface of the rear seat and the backrest.
  • Figure 6B shows the compressive force that is applied by shoulder restraint belt 14 according to an embodiment of the present invention.
  • FIG. 6C shows the compressive force that is applied by an alternate restraint device according to an embodiment of the present invention.

  • This also provides an urging force F2 that urges at least a portion of a rear contact surface 50 of the divider against seat backrest 82 of the motor vehicle.
  • FIG. 7 shows some optional features that can be added to rear seat divider 10 in alternate embodiments.
  • One or more pockets 28 can be sewn into or otherwise affixed to pliable covering 74, for example.

  • Figure 9B shows a rear and side view of the rear seat divider with indentations formed in the block of core material, allowing improved access to restraint belt connections.
  • the cut-out portions can improve access to the inner buckle/connector of the side seating positions as well, thereby facilitating insertion/removal of children and/or their safety seats.
  • rear seat designs have the same geometry, with respect to factors such as the relative angle between backrest 82 and seat bottom surface 80 and front-to-back curvature of the seat portion and, considered orthogonally from side to side, with respect to the shape of the mid-section of the rear seat.
  • Rear seats in some automobiles, for example, have a protuberance or hump in the mid-section; rear seats in others do not. Because of such differences in rear seat geometry, it can be difficult to maintain good frictional contact at all points.
  • rear seat divider 10 has curved rear and base contact surfaces 50 and 52 in the embodiment shown. Because of the relative flatness of the rear seat bottom 80 that is shown, there are two contact points CI and C2, shown as open circles in Figure 10A, for frictional contact between divider 10 and the rear seat bottom surfaces, considered from this side view. Considered in three dimensions, this means that there is contact between divider 10 and the rear seat along two lines, each line running orthogonal to the page as Figure 10A is represented; each line intersecting one of points CI and C2. This can be improved over single line contact, which can be the case with a convex seat and a flat rear seat divider surface (assuming poor conformance of the rear seat divider). In practice, a conformable rear seat divider with flat to mildly concave surfaces has been found to conform well to a variety of rear seats when under mild compression, providing broad areas of contact for enhanced friction and stability.
  • Figure 10B shows an embodiment with base contact surface 52 having a concave curvature along a direction orthogonal to that shown in Figure 10A.
  • the contoured arrangement shown in Figure 10B now provides contact points C3 and C4 from this cross-sectional view.
  • the same approach can be taken along rear contact surface 50 with respect to its contact points shown at C5 and C6. In this way, by providing concave curvature to one or both rear and base contact surfaces 50 and 52, the same considerations described above for Figure 10A become apparent here.
  • this embodiment is most advantaged for convex seat geometries.
  • a conformable rear seat divider with flat to mildly concave surfaces has been found to conform well to a variety rear seats when under mild compression, providing broad areas of contact for enhanced friction and stability.
  • contoured arrangement of these surfaces can be advantageous when used in combination with shoulder and lap restraint belts 14 and 12.
  • the curvatures of both rear and base contact surfaces change, urged toward the rear seat surfaces when the restraint belts are used. This effectively increases the radius of curvature for the contoured surfaces, increasing the surface contact area at the same time for a more stable seating of divider 10.
  • Rear seat divider 10 can be further outfitted with storage pockets, fold-down elements such as trays or holders, and other features. It may also have a see-through or pass-through hole or slot for visibility between adjacent children, for example.
  • various design elements could be used to make rear seat divider 10 more appealing for younger children, such as using various graphical elements and approaches.
  • Other embodiments include design of divider 10 as a plush toy article. Three- dimensional features formed in the pliable covering can be used for aesthetic purposes, such as to make divider 10 appear more desirable, for example, a face, a person, an animal, a robot, a brick wall, a cartoon character, a slice of watermelon, or anything else desired.
  • Divider 10 (or its pliable covering) may also incorporate any conceivable two- dimensional graphical design as well, such as the features of a face or licensed character likeness or an abstract pattern or color, as desired.
  • the divider can be made nondescript, such as in a neutral color, or may be made to match the automobile interior as well.
  • divider 10 is preferably easily cleanable. This is preferably achieved via an easily washable/wipeable surface or via a removable/washable fabric covering, for example. Alternately, or additionally, the divider could incorporate a stain-resistant surface for minimizing the need for cleaning.
