Height-adjustment device for a motor-vehicle safety belt
First Claim
1. A device for adjusting the height of the upper mounting or guide fitting of the safety belt of a motor vehicle;
- said device comprising;
a guide rail having two sides on which are successively arranged, one above the other, arresting openings;
a slide which is movable in said guide rail and carries said guide fitting;
locking elements adapted to engage in said arresting openings, said locking elements being displaceable transversely to the direction of movement of said slide, against spring pressure, from one extreme position, a locked position, into a second extreme position, an unlocked position, and vice versa;
at least one of said locking elements being provided with a first extension;
at least one push button for effecting said displacement of said locking elements; and
a guide member which is operatively connected with said at least one push button, and is provided with at least one inclined guide into which said at least one first extension of said locking elements engages;
the length and path direction of said at least one inclined guide being such that the associated locking element is displaced from one of said extreme positions to the other when said first extension thereof traverses said inclined guide so that on the one hand unlocking movement of said locking elements is avoided in the direction of forces effective during a side impact encountered by the vehicle and on the other hand there is made possible that a push button movement is converted into a locking movement arranged at right angles thereto via said inclined guide.

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.
