Title: HEADREST WITH AN IMPROVED ADJUSTMENT DEVICE
Abstract:
The invention relates to a headrest for a motor vehicle, with a base part (3) for fastening to a backrest of a vehicle seat, and a head part (4) designed for support of a vehicle occupant's head, and an adjustment device (2, 20) between the base part (3) and head part (4) in order to bring about a substantially linear adjustment of the head part (4) between a minimum position and a maximum position relative to the base part (3), wherein the adjustment device (2, 20) has an intermediate part (7) and a plurality of pivot levers (8, 9) which pivot synchronously with a pivoting movement during the adjustment and are arranged and designed in such a manner that at least one first joint parallelogram (10) is formed between the head part (4) and the intermediate part (7), and at least one second joint parallelogram (11) is formed between the intermediate part (7) and the base part (3), and the adjustment device (2, 20) has at least one further synchronizing lever (12) between the head part (4) and the base part (3) in order to fix a relative orientation of the head part (4) with respect to the base part (3) during the adjustment and to synchronize the pivoting movement of the pivot levers (8) of the first joint parallelogram (10) with the pivoting movement of the pivot levers (9) of the second joint parallelogram (11), wherein the headrest furthermore has a latching device (13, 16; 21, 23) in order to fix the head part (4) in a latching manner relative to the base part (3).
