Mounting system for a headrest retractable by gravity, assembly comprising such a mounting system and vehicle seat comprising such an assembly

摘要

A mounting system for a headrest comprising at least one shaft, the system comprising a housing adapted to enclose the shaft with a radial clearance, a moving carriage capable of being moved between a blocking position and an unblocking position, and a jaw movable between an immobilization position and a release position. The jaw is adapted to apply, when it is in the immobilization position, a clamping force to the shaft in a clamping direction perpendicular to the vertical direction, so that the shaft is supported on the housing. The moving carriage comprises at least one drive slot in which a slug from the jaw is able to move.
