ABSTRACT:
A seatbelt lock is mounted to be movable as little as possible relative to the seat surface when the seat surface is adjusted in height or inclination. The seat has a longitudinal guide 20, 22, a device 24 for adjustment of height or inclination and a belt lock attachment 32. The lower end of the belt lock attachment 32 is affixed to the seat rail 22 of the longitudinal guide and carries a belt lock 34 at its upper end. The belt lock attachment has a lower part 38 linked to the seat rail and an upper part 40 linked to the seat carrier 26, the upper part being connected with the belt lock. One of these parts 38, 40 can move freely in a longitudinal guide formed by the other part. One part has at least one locking projection 60; and the other part has locking devices 46 interacting with the projection. By means of a safety piece 50, the two parts are held in a normal position permitting movement. When extreme forces induced during an accident act on the belt, the safety piece is overridden, whereby the locking projection engages in the locking device and removed of the upper part from the lower part is precluded.
