ABSTRACT:
The present invention relates to a motor vehicle seat with an adjustable reclining backrest, which is articulated to the seat frame on both sides using tilt adjusting fittings. Both tilt adjusting fittings are coupled to each other by a rigid connecting tube, which is formed as a hollow section or at least in the zone of the tilt adjusting fittings as a hollow section. It is used for the simultaneous adjustment of both tilt adjusting fittings by means of a driving device arranged on one side of the seat. The connecting element is fastened bilaterally to one of the two tilt adjusting fittings, so that it is secured on both sides against an axial movement. The object of the invention is to improve this type of seat so that a folding back or opening of the tilt adjusting fittings is prevented while at the same time mounting of the connecting elements without problematic rattling and axial jamming is made possible. Said object is achieved in that the connecting element (5) has a stop (21) on the outside of the other tilt adjusting fitting (3) with an axial play (22) relative to said tilt adjusting fitting (3), which is smaller than the width (b) of the locking toothing (8).
