Abstract

L'invention concerne une armature (10) pour un siège de véhicule comprenant une première partie d'armature (11), une deuxième partie d'armature (12) qui peut tourner par rapport à la première partie d'armature (11) et plusieurs verrous (16) qui interagissent avec la première partie d'armature (11) en étant guidés par la deuxième partie d'armature (12) au moyen de segments de guidage (14) et qui présentent des côtés longs (46) qui font face aux surfaces de guidage (14a) des segments de guidage (14). Selon l'invention, les côtés longs (46) sont à chaque fois divisés au moyen d'un premier talon (46a) en une première section (46b) intérieure dans le sens radial et une deuxième section (46c) extérieure dans le sens radial et les surfaces de guidage (14a) sont divisées au moyen d'un deuxième talon (48a) en une première surface (48b) intérieure dans le sens radial et une deuxième surface (48c) extérieure dans le sens radial. Toujours selon l'invention, au niveau des côtés longs (46) du verrou (16), les deux premières sections (46b) présentent un écart entre elles supérieur à celui entre les deux deuxièmes sections (46c) et, dans le cas de deux surfaces de guidage (14a) se faisant respectivement face l'une à l'autre, les deux premières surfaces (48b) présentent un écart entre elles supérieur à celui entre les deux deuxièmes surfaces (48c).
