Lock for fixing a seat of a motor vehicle to a floorpan of the vehicle

Abstract

A lock including a lock bolt (12) equipped with a locking body (14) of cylindrical overall shape intended to be locked by snap-fitting into a locking orifice (16) of complementary shape made in a striker plate (18). The lock bolt (12) additionally includes an anti-hammer ring (76) surrounding a region of the locking body (14) which, when the lock bolt (12) is locked, is in contact with the periphery of the locking orifice (16). As a preference, the body (14) is equipped with a releasable snap-fitting mechanism including bearing limits (40) for axial bearing which are intended to interact with a first face (36) of the striker plate, and at least one retractable locking ball (42) intended to interact with a second face (38) of the striker plate. When the lock bolt (12) is locked, the anti-hammer ring (76) extends axially between the bearing elements (40) and the ball (42), lying adjacent to the first face (36) of the striker plate.
