Abstract

The invention relates to a longitudinal seat adjustment system for seats, comprising two pairs of rails (10) which are set apart from each other. Said pairs of rails each consist of two U-shaped rails, an upper rail (11) and a lower rail (12). These two rails (11, 12) can be switched to a locking position or a release position by means of at least one spring-loaded, plate-shaped locking part (21). Said locking part (21) has teeth (15) on two opposite sides, these teeth engaging in recesses (14) or openings (16) in the rails. According to the invention, the edge areas (44) of the tooth-like recesses (14) in the lower rail (12) and/or the edge areas (45) of the slit-like openings (16) in the upper rail (11) are permanently deformable. Consequently, in the locking position, the teeth (15) of the plate-shaped locking part (21) which engage in the openings (16) and recesses (14) deform the edge areas of said opening (16) or recesses (14) in the event of a considerable load, for example in an accident.
