Abstract: An apparatus for adjusting the height of the upper fixing or guide fitting for the shoulder belt of a safety belt system, particularly in motor vehicles. The apparatus includes a guide rail mounted on part of the vehicle body, and has a guide slot and recesses in which at least one associated locking member engages. This locking member is mounted on a sliding member which carries the fixing or guide fitting and is capable of being locked in or released from the recesses via a handle. The locking member or locking members are symmetrical in construction with regard to their locking function, are mounted on the sliding member, and are operative in the guide rail, and especially are operative on both sides of the central longitudinal line of the guide rail. Moreover, the handle is designed, by a finger pressure construction, to be operated with substantially no force of the hand and arm, using one hand.

Abstract: A device for adjusting the height of the upper mounting or guide fitting of a motor-vehicle safety belt. The device includes a guide rail having arresting openings arranged above one another on both sides, and a slide which is movable in the guide rail, carries the mounting or guide fitting, and has locking elements which are displaceable transversely to the direction of movement of the slide, against spring pressure, from a locking position into an unlocked position via at least one push button. Problems to be overcome, on the one hand, include being able to carry out convenient and safe adjustment by hand and, on the other hand, preventing automatic adjustment as a result of uncontrollable external influences.
