This leads to the desired minimal surface pressure. If the holding elements 12, 14 are then in motion due to movement with a smaller area or only at least linearly in contact, the holding force is practically zero, so that even then Surface pressure is small. This significantly reduces wear due to friction.

This means that in principle practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.

Abstract

L'invention concerne un système de retenue de porte à charnière, en particulier pour portes d'un véhicule automobile, comprenant deux éléments de charnière (2, 4) reliés entre eux pivotants autour d'un axe de rotation (8) au moyen d'un tourillon (6) de charnière, et un dispositif d'arrêt (10) permettant l'arrêt mutuel desdits éléments de charnière (2, 4) en diverses position de pivotement relatif. Le dispositif d'arrêt (10) comprend au moins deux éléments d'arrêt (12, 14) coopérant, en prise chacun avec l'un des éléments de charnière (2, 4). Par mouvements de pivotement relatifs des éléments de charnière (2, 4), l'un (14) des éléments d'arrêt est déplacé en direction de prise (26), par rapport à l'autre élément d'arrêt (12). Il est prévu un dispositif amortisseur (30) permettant un amortissement des mouvements de prise de l'élément d'arrêt (14), de telle façon que ledit élément d'arrêt (14) s'éloigne, lors de son déplacement, par un mouvement pivotant relatif initial, de l'autre élément d'arrêt (12), et demeure essentiellement dans cette position pendant un mouvement pivotant dynamique, et ne retourne, qu'en fin de pivotement, sous amortissement, à l'encontre de l'autre élément d'arrêt (12).
