Abstract
A headrest for a motor vehicle seat is crash active in that it has a mechanism for automatically bringing the head-engaging member toward the head of the passenger in the case of a crash. This mechanism includes a slide guided on a pair of cylindrical members surrounded by springs and having a tooth-forming part of a return travel lock preventing return of the slide to its starting position. In that position a releasable coupling device has a primary coupling element engaged with a secondary coupling element which may be a hairpin-shaped bent wire.
