To be able to adjust the height of the belt, The Beamings of these elenents have to be very weak so that the entire headrest is not adjusted when it is adjusted from the seat back · is lifted · but with it they also give in the event of an accident, each larger pressure in the adjustment direction after and do not offer the security required of a headrest

Supports have also been proposed, including the pivot positions are fixable, ζ · Β · by means of crown locks ·

The basic idea of the present invention is a headrest au create that through sufficient Terstellmugliehkeit the There are so many seats on the back of the vehicle optimally adaptable to different body sizes of the user

Oils of the invention corresponding height adjustment of the support can be done either if the head part of the column, i.e. above it the pivot axis of the support, which is particularly suitable for plug-on headrests, or it can take place in the seat backrest, So below the swivel axis · This solution is particularly suitable for »built-in headrests that are permanently attached to the vehicle seat.

To determine the height adjustment you can according to the invention go different ways. An example is a shear " * pin that engages in holes in Terstellschienen and can be released by means of a lever during adjustment. Another example are clamping bodies, which after the Adjustment e.g. by thrust wedges, radial or axial θ Threatening wedges are clamped immovably in the corresponding counter-forms of the adjustment rails.

The sliding or rotating wedges can also be used for direct stepless Clamping smooth or profiled adjustment rails can be used · Instead of the wedge elements kunaen in the The above-mentioned fillings just as easily step with the clamping screws
