Abstract

L'invention porte sur un procédé de fabrication d'un ensemble palier et sur une ferrure pour siège de véhicule possédant un ensemble palier fabriqué selon ce procédé. L'invention concerne un procédé de fabrication d'un ensemble palier pour un véhicule, en particulier pour un siège de véhicule, qui présente un premier élément de palier (12) et un second élément de palier (16) mobile par rapport au premier dans une direction de mouvement (r), procédé dans lequel tout d'abord le premier élément de palier (12) reçoit le second élément de palier (16) avec un grand jeu indéfini dans une direction de jeu (p) perpendiculaire à la direction de mouvement (r) et, plus tard, le premier élément de palier (12) et/ou le second élément de palier (16) sont déformés par déformation plastique sous l'action d'efforts dans une direction d'emboutissage (x) jusqu'à ce que le premier élément de palier (12) et le second élément de palier (16) soient appliqués l'un contre l'autre sans jeu dans la direction de jeu (p). Dans ce procédé, selon l'invention, après la réception du second élément de palier (16) par le premier élément de palier (12) et avant la déformation plastique, le premier élément de palier (12) est déformé par déformation élastique avec réduction du jeu et, après la déformation plastique, la déformation élastique s'inverse de sorte que l'on obtienne un ajustement à jeu défini entre le premier élément de palier (12) et le second élément de palier (16).
