Abstract
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. To make the adjustment device easy to operate, shock-proof, and at the same time also practicable for smaller motor vehicles, there is located on the push button a guide member which has at least one inclined guide into which an extension of the associated locking element engages; the length and path direction of the inclined guide are such that the associated locking element is displaced from one extreme position to the other when the locking element traverses the inclined guide via the extension. The extensions of the locking elements, and the associated inclined guides, are preferably made to engage positively.
