Title: HEADREST RETRACTOR FOR A VEHICLE SEAT, IN PARTICULAR A MOTOR-VEHICLE SEAT, AND VEHICLE SEAT
Abstract:
The invention relates to a headrest retractor (300) for a vehicle seat (1), in particular a motor-vehicle seat, the vehicle seat (1) having a lower seat part (10) and a backrest (20). The backrest (20) is adjustable in the tilt thereof relative to the lower seat part (10). The backrest (20) can be pivoted from a usage position toward the lower seat part (10) into a non-usage position and back into the usage position. The headrest retractor (300) retracts a headrest (50) from an originally set position within a comfort setting range (S1) into a lowered position during the pivoting of the backrest (20) from the usage position into the non-usage position and extends the headrest (50) toward the originally set position, in particular into a lowermost position within the comfort setting range (S1), during pivoting of the backrest (20) from the non-usage position into the usage position. The headrest retractor (300) has a carrier (310), a slide (330), which can be slid relative to the carrier (310), the slide (330) having receptacles (332) for receiving headrest rods (60), and the headrest rods (60) being guided for relative sliding in the receptacles (332), and a headrest drive (340) for driving and/or controlling the relative sliding between the slide (330) and the carrier (310). The headrest drive (340) can be interlockingly locked in such a way that relative sliding between the slide (330) and the carrier (310) is blocked. The invention further relates to a vehicle seat (1), in particular a motor-vehicle seat, comprising a lower seat part (10), a backrest (20), and such a headrest retractor (300).
