Ferrure articulée pour siège à dossier réglable. Articulated fitting for seat with adjustable backrest.
La présente invention concerne une ferrure articulée pour siège à dossier réglable, en particulier pour un siège de véhicule automobile, dans laquelle un élément de l'articulation qui est The present invention relates to a hinged fitting for an adjustable back seat, in particular for a motor vehicle seat, in which an element of the hinge which is

direction de l'organe de réglage opposé. direction of the opposite adjusting member.
L'inconvénient de cette ferrure est que, lorsqu'il y a un accident pendant la circulation du véhicule, les montants latéraux du dossier sont si fortement sollicités que la liaison de ceux-ci avec les éléments de l'articulation de la ferrure qui sont associés au dossier, par exemple la soudure, se rompt, les occupants du véhicule qui sont assis sur les The disadvantage of this bracket is that, when there is an accident during the vehicle traffic, the lateral amounts of the backrest are so heavily stressed that the connection thereof with the elements of the hinge of the fitting which are associated with the file, for example welding, breaks down, the occupants of the vehicle sitting on the
sièges avant étant de ce fait en grand danger. front seats are therefore in great danger.
C'est ce point qui est concerné par l'invention L'invention a pour but de perfectionner cette ferrure articulée connue de It is this point which is concerned with the invention The object of the invention is to improve this articulated fitting known from

Selon l'invention, ce problème est résolu du fait que le tourillon pénètre dans l'extrémité du tube transversal qui According to the invention, this problem is solved by the fact that the trunnion enters the end of the transverse tube which

Selon une forme de réalisation préférentielle de la ferrure According to a preferred embodiment of the fitting

Avantageusement, le tourillon porte un renflement annulaire arranged by an eccentric on which is mounted free rotation a toothed wheel, some teeth of the toothed wheel meshing during its tilting movement with some of the teeth of a ring gear internally disposed in the element of the joint associated with the folder, the trunnion and the transverse tube have a circular section. Advantageously, the trunnion carries an annular bulge

Deux exemples de réalisation de la ferrure articulée selon The backrest is partially absorbed by the trunnion which penetrates the tube, the total stress then being approximately reduced by half. As a result, the total stresses which appear are very greatly reduced. Two embodiments of the hinged fitting according to

La référence 1 désigne un élément de l'articulation qui est associé au siège et qui est le plus souvent fixe, alors que la référence 2 désigne un élément de l'articulation qui peut pivoter par rapport au premier et auquel est fixé le montant latéral associé 3 du dossier, cette fixation étant réalisée tion.

Le pivotement de l'élément de l'articulation 2 qui est associé au dossier, par rapport à l'élément de l'articulation 1 qui est fixe, s'effectue par l'intermédiaire d'un dispositif de réglage Les dispositifs de ce type sont connus en soi Dans The pivoting of the element of the articulation 2 which is associated with the backrest, with respect to the element of the articulation 1 which is fixed, is effected by means of an adjustment device. Devices of this type are known per se

Les deux montants latéraux 3 du dossier sont reliés l'un à l'autre par un tube 8 qui est disposé parallèlement au rebord the backrest can then be tilted forwards or backwards.

Comme le montrent les figures 2 et 3, il est prévu sur chaque excentrique 5 un tourillon 5 a qui pénètre dans l'extrémité voisine du tube 8 Dans la forme de mise en oeuvre représentée sur le dessin, le tourillon 5 a aussi bien que le tube 8 ont une section transversale de forme circulaire Mais l'invention n'est limitée en aucune manière à cette forme de réalisation particulière. Lorsqu'il y a un accident, une partie des sollicitations qui apparaissent sont absorbées par les cordons de soudure 4 alors que la partie restante des forces est absorbée du fait que les deux tourillons Sa des excentriques 5 s'appliquent contre la As shown in Figures 2 and 3, there is provided on each eccentric 5 a pin 5 which penetrates into the adjacent end of the tube 8 In the embodiment shown in the drawing, the pin 5 has as well as the tube 8 have a circular cross section. But the invention is not limited in any way to this particular embodiment. When there is an accident, part of the stresses that appear are absorbed by the weld beads 4 while the remaining part of the forces is absorbed because the two pins Sa eccentric 5 apply against the
