Definitions
- the present invention relates to a reclining seat device, in particular for a sick or disabled occupant, comprising a frame arranged to rest on the ground, a seat mounted on the frame by means of at least one articulation with transverse horizontal axis, to be reclining in a range of tilt positions, and positioning means arranged to stabilize the seat in at least one of said positions when the seat supports the weight of the occupant, in which the positioning means include locking means capable of blocking the inclination of the seat in any position in said range and to be controlled manually, and elastic means connecting the seat to the frame and defining a vacuum equilibrium position when the seat is not occupied, the elastic means being arranged to exert a return torque on the seat towards the empty equilibrium position when the seat has a different position nte thereof, the restoring torque being increasing when the seat moves away from said equilibrium position, and in which at least some of the elastic means are associated with said articulation.
- Reclining seat devices are known in which it is possible to modify and lock the inclination of the seat manually, by means of a notch mechanism.
- US Patent 2 '986' 200 shows for example a wheelchair for invalids in which the tilting articulation of the seat is associated with a locking mechanism and with return springs which oppose the tilting torque produced by the weight of the occupant, in order to stabilize the seat and allow it to be maneuvered with little effort.
- the springs must be relatively strong and do not allow a good agreement to be obtained between the variation in the return torque and the variation in torque due to the weight of the occupant. It is therefore necessary to exert a force large enough to put the seat in a position distant from the position of equilibrium, or to bring it there.
- Patent application FR 2 '693' 889 describes a tilting chair device also having elastic means associated with the joint, in the form of a torsion spring, and blocking means arranged at a distance from the joint, in the form of a fluid cylinder whose piston brakes tilting and includes a blocking valve controlled by the occupant.
- the piston When it is unlocked, the piston cannot contribute to the tilting of the seat, but only oppose a rapid movement.
- the spring must be relatively strong, as in the above-mentioned prior art.
- the hinge pin is placed in the vicinity of a vertical passing through the center of gravity of the occupant.
- the occupant could then control the tilting movements by movements of his body, for example of the bust, to change the position of his center of gravity and thus produce a tilting of the seat after unlocking.
- these movements of the body must have a certain magnitude when the center of gravity must pass from one side to the other of the support joint. In such a case, if they are easy enough for a valid person, they can be painful, even impossible, for a sick or handicapped person. In addition, premature release or too late blocking of the blocking member can lead to abrupt maneuvers and incidents.
- Swiss patent 681,772 shows an office chair with reclining seat mounted on an elastic joint provided with rubber elements, as well as a front stop and a rear stop which limit the range of possible tilt. There are no locking means in intermediate positions. Such a device is not applicable to a seat for the sick or disabled. If it were adapted to such an application, it would require particularly strong and heavy elastic elements. A weight saving is an important criterion in the design of a wheelchair, in particular with manual propulsion.
- GB 2 '029' 334 discloses a type of reclining seat device in which the positioning means are formed by a manual or motorized actuator, for example a hydraulic, pneumatic or electric linear actuator, which controls 1 spacing between two respective points of the frame and the seat at a certain distance from the axis of articulation.
- a manual or motorized actuator for example a hydraulic, pneumatic or electric linear actuator, which controls 1 spacing between two respective points of the frame and the seat at a certain distance from the axis of articulation.
- the actuator In order for a sick or disabled occupant to be able to modify the inclination of the seat himself, the actuator must be able to operate when the seat is occupied, and therefore be dimensioned so as to produce a force large enough to overcome the maximum torque resulting from the weight. of the occupant in any position of the seat. This negatively influences the weight, size and cost of the positioning means, as well as their energy consumption. If the actuator is manual, the operation by a sick or disabled occupant can be quite difficult and trying.
- a first aspect of the invention relates to a reclining seat device as defined in the preamble, characterized in that the elastic means further comprise a gas spring arranged to exert a force between the frame and the seat at a distance of the hinge pin, said force being substantially constant at least when the locking means are released.
- the empty equilibrium position will be located rather towards the front and preferably the gas spring will be arranged so that its force opposes a tilting towards the rear, where the torque due to the weight of the occupant is relatively large.
- the elastic means incorporated in the joint can be weaker, lighter and less costly.
- the locking means are associated with the gas spring and arranged to block or unblock the latter on command, the gas spring being of a type with substantially constant force when it is released.
- the gas spring is used for both elastic means and locking means, this represents a saving of material and weight.
- the cylinder exerts the reaction force necessary to maintain the seat in the chosen position.
- a second aspect of the invention relates to a reclining seat device as defined in the preamble, characterized in that the positioning means comprise a jack with motorized drive, placed at a distance from the axis of the articulation, said jack connecting the frame at the seat for controlling the inclination of the seat and forming part of the locking means.
- the combination of the elastic means associated with the articulation and of the motorized jack ensuring both the positioning and the locking of the seat in any position within the range of inclination offers several advantages. Thanks to the elastic return torque, it is possible to use a jack whose force and energy consumption are very reduced.
- the jack being able for example to be an electric jack powered by a battery or a small accumulator incorporated in the device according to the invention.
- the actuator fulfills both positioning and locking functions
- the axis of the articulation is located near a vertical passing through the center of gravity of the occupant when the seat is in said position vacuum balance.
- the seat is preferably tiltable forward and backward relative to the idle equilibrium position.
- the elastic means comprise at least one elastic bearing forming said articulation and comprising rubber elements arranged to produce at least part of the restoring torque.
- the seat can have a seat, mounted on the frame, and a backrest tiltably mounted on the seat by means of another articulation associated with elastic return means urging the backrest.
- the device is produced in the form of a wheelchair or a stroller for the sick or disabled.
- the frame comprises two main wheels arranged along a common central axis located near a vertical passing through the common center of gravity of the device and the occupant, at least one steerable front wheel located in front of the axis central, and at least one rear safety caster arranged to rest on the ground at least in the event of the device tilting backwards around the central axis.
- Said rear caster can advantageously be movable in height on the frame, to which it is linked by elastic return means capable of pressing it on the ground at least when the device tends to tilt backwards around the central axis.
- Figure 1 is a schematic side view of a device according to the invention, the seat of which is in a position of load balance;
- Figure 2 is a schematic view of the rear of the device;
- Figure 3 shows in perspective an element forming an elastic bearing in the device of the figures
- FIG. 4 is a schematic diagram representing a typical example of a torque-angle characteristic curve of pivoting of an elastic bearing according to FIG. 3.
- the reclining seat device according to the invention is made in the form of a stroller for the sick or disabled.
- the same construction principle would apply to a stationary seat or a wheelchair, whether the latter is powered by the occupant himself or by a motorized drive incorporated in the wheelchair.
- the stroller 1 shown has a lower frame
- a reclining seat 3 which are connected by a joint 4 with a horizontal axis 5 and by a retaining element which, in the present case, is a gas spring 6 provided with an incorporated locking device.
- the frame 2 mainly comprises a rigid chassis composed of longitudinal metal tubes 10, 11, transverse 12 and vertical 13, 14, two main lateral wheels 15 centered on a common transverse axis 16 and two front wheels 17 freely orientable around a vertical axis , the wheels 15 and 17 resting on the ground 18 to support the entire stroller under normal conditions.
- the two main wheels 15 are mounted on an axle 19 which is fixed to the chassis, preferably in a longitudinally adjustable position.
- the frame 2 still has two bent crutches 20, each carrying a rear safety roller 21 which, normally, is slightly above the ground 18, but can lean against it to prevent a possible tilting of the chair backward around the axle 16 if the front wheels 17 are raised for any reason.
- the crutches 20 are fitted into the horizontal tubes 10 of the chassis, where they are fixed in a longitudinally adjustable position.
- the frame 2 could comprise a single front wheel 17 and / or a single rear wheel 21.
- a motorized drive system actuating the main wheels 15, in the case of a motorized wheelchair.
- This frame could also be that of a manual drive wheelchair if the main wheels 15 were arranged accordingly, in particular with an annular handle which is within easy reach of the occupant.
- the frame of the frame 2 further comprises two supports 22 on which are fixed, by means of metal flanges 23, two pivoting elastic bearings 24 which will be described later and are aligned on the axis 5 to form the joint 4 together.
- the seat 3 comprises a rigid metal frame 26 supporting a padded armchair 27 on which the occupant 28 takes place.
- the frame 26 carries an adjustable footrest 29.
- the rear it carries two inclined arms 30 provided with handles 31 to allow an auxiliary person to move and direct the stroller 1.
- One of the handles 31 is equipped with a lever 32 which controls, for example, by means of a cable transmission 33, the release of the jack 6
- the arms 30 are integral with the backrest 34 of the chair 27 and are mounted on the chassis 26 by means of a pair of articulations 35 making it possible to adjust the inclination of the backrest relative to the seat 36 of the chair.
- These joints can also include elastic return means, for example elastic elements similar to those of the bearings 24.
- FIG. 3 shows the structure of one of the elastic bearings 24 forming the articulation 4.
- ROSTA registered trademark
- This element comprises a square outer tube 40 of steel, a square inner tube 41 also of steel, disposed inside the outer tube without touching it, and four rubber blocks 42 of prismatic shape with approximately triangular section.
- the blocks 42 are arranged in the corners of the outer tube 40 and each rest on one face of the inner tube 41 which, in its rest position, is turned 45 ° relative to the outer tube 40, the blocks 42 being slightly compressed between the two tubes.
- this assembly resiliently supports the internal tube 41 in all directions and allows it to pivot by an angle ⁇ ⁇ around an axis 5 from the rest position, this angle ⁇ possibly reaching at minus 30 °.
- one end of the tube 41 of each elastic bearing 24 is fixed to the chassis 26 of the seat by means of a metal flange 44.
- the rubber blocks 42 exert on the tube 41 a return torque M which increases progressively with the angle ⁇ . As shown in FIG. 4, this progressiveness is not linear, the variation of the torque M being relatively small for the small values of the angle ⁇ , and higher when the angle becomes larger.
- the deformation-stress diagram of the rubber blocks presents a hysteresis which results in a difference between the load curve 61 and the discharge curve 62, in FIG. 4
- the elastic bearing 24 also constitutes a shock absorber for all the vibrations of a tube 40, 41 relative to each other, both in translation and in rotation.
- the jack 6 is a gas spring with constant force and automatic locking, of the BLOC-O-LIFT type (registered trademark) manufactured by the company STABILUS in Koblenz (Germany) When is released, it exerts a constant pushing force F of 500 N. Its lower end is articulated on a support 45 secured to a crosspiece 46 fixed to the tubes 10 of the chassis in an adjustable position. Its upper end is articulated at 47 at a rear end of the chassis 26 of the seat.
- gas spring 6 does not necessarily have to be provided with a blocking device. This could be a member separate from the jack, for example in the form described in patent application FR 2 693 889. However the combination described here has the advantage of combining the two return and blocking functions in a single member , which saves weight and space.
- the position of the articulation 4 relative to the seat 3 is such that when the occupant 28 normally rests on the seat, a vertical gl passing through the center of gravity Gl of the occupant passes close to the axis 5 of the joint, at least when the seat is in the so-called empty equilibrium position.
- the seat is preferably rather straightened, so that the footrest 29 is not too high and that the occupant can sit easily. It is then preferable for the vertical gl to be slightly behind the articulation axis 5, so that it suffices to unlock the jack 6 so that the seat automatically reclines to the rear under the effect of the torque produced by the weight of the occupant.
- the seat 3 stabilizes in a position of load balance, where the torque due to the weight of the occupant is counterbalanced by the torque resulting from the elastic elements 6 and 24. This results in a load equilibrium position specific to each position of the occupant.
- To define another tilt position simply raise or lower the handles 31 and release the lever 32 to lock the cylinder 6 when the desired position is reached.
- the release control of the actuator 6 may also include a control handle 48 disposed on the seat 3 so as to be accessible to the occupant, so that the latter can maneuver him - even the seat.
- This command replaces that of the controller 32 in the case of a wheelchair.
- the occupant wants to modify the inclination of the seat 3 himself, he modifies if necessary the position of his center of gravity Gl by moving a part of his body, for example by slightly advancing his head, his bust or an arm if it wants to tilt forward, and it unlocks the jack 6.
- the central axis 16 of the main wheels 15 is located near a vertical g2 passing through the common center of gravity G2 of the device 1 and the occupant 28, this vertical being slightly forward of the axis 16 for any position of the seat 3 so that the front wheels 17 rest on the ground. So it's easy to tilt back the entire device 1, including its frame 2, around the axis 16 for lifting the front wheels when they have to cross an obstacle such as a threshold or a curb. The tilting is then stopped by the rear rollers 21.
- the arms 20 can also be mounted on the frame 2 in an elastic manner, for example by means of elastic ROSTA elements similar to those of the bearings 24 and forming a joint 50 (FIG.
- each caster 21 is movable in height on the frame, according to a principle described in patent application WO 96/15752 from the same applicant.
- the rollers 21 can bear lightly on the ground even in the normal position of the frame in accordance with FIG. 1, where the front wheels 17 also touch the ground, and their bearing force will increase if the whole of the device tends to tip back.
- a reclining seat in combination with such a progressive elastic support of the rear caster (s) 21, makes it possible to use a change in inclination of the seat to easily move the center of gravity of the occupant in order to produce a transfer load the front wheels to the rear castors or vice versa, in particular to take advantage of the elasticity of the support on the rear casters.
- the gas cylinder 6 described above was replaced by a simple blocking member, that is to say if one did without the constant thrust exerted by this cylinder, the torque of return would then be produced only by the elastic bearings 24.
- the jack 6 has the advantage of exerting a prestress on the elastic bearings, which results in a higher return torque as soon as the seat deviates from its position of balance.
- the choice of the position of the jack 6 makes it possible to adjust its distance to the axis of the articulation and therefore to modulate the torque produced by its force F.
- Another variant consists in making the articulation 4 by means of ordinary bearings, the restoring torque then being provided by one or more spring elements connecting the seat 3 to the frame 2, for example with a torsion spring associated with the articulation 4.
- a linear or rotary motorized actuator for example an electric actuator 51, controlled by the occupant to modify and block any seat tilt position 3.
- This cylinder 51 also serves as a locking member which maintains the position of the seat 3.
- a control unit 52 of the cylinder 51 mounted on the seat 3 within easy reach of the occupant 28, and an electric battery 53 mounted on the frame 2 to power the jack 51.
- the housing 52 includes push buttons or a lever for controlling the jack 51. Thanks to the elastic return means , such an actuator may have a reduced nominal force compared to conventional devices, which allows savings in weight, size and manufacturing cost, as well as savings in operating energy.
- the device can be stationary and devoid of wheels.
- the frame 2 can be a simple base resting on the ground, or generally any structure capable of supporting the seat 3 and the joint 4, for example in a medical or dental office, or in a vehicle.
