ABSTRACT:
The device relates to vehicle seats in which the backrest armature is composed of two uprights which are articulated with respect to the seat part armature about a first transverse horizontal pin in order to define various positions of comfort and about a second pin, parallel to the first one, in order to allow the backrest to be folded down onto the seat part, the latter articulation being associated with an unlockable immobilizing structure. For each upright, the first articulation with respect to the seat part armature is provided by a lever including, above its part that is journal-mounted on the first articulation pin, a tenon of rectangular section which fits into a central housing formed in the section piece constituting the corresponding upright, whereas in the second articulation, the pin is borne by the aforementioned tenon and interacts with at least one mounting plate which, arranged against the lever, is set tightly into the housing of the section piece to which it is fixed by riveting, this mounting plate having a lower end protruding beyond the upright and locally fitted with toothing designed to interact with complementary toothing borne by a mechanism for immobolizing the upright with respect to the lever.
