A head rest (1) for motor vehicle seats has a centre part (3) and side parts (5a, 5b) that are arranged on either side of the centre part (3) and can be adjusted relative to the centre part (3) to provide lateral support of the head. In order to actuate the adjustment of at least one side part (5a, 5b), at least one hollow body (7) that can be filled with fluid is provided, by the filling of which the at least one side part (5a, 5b) is pivoted in the direction of the area (B) in which the head is accommodated. The hollow body (7) that can be filled with fluid is arranged on the side of the centre part (3) facing away from the head accommodation area (B). Two lever arms (8a, 8b) pivotable about a respective pivot axis (9a, 9b) are provided, each having a first lever arm section (8a1, 8b1) and a second lever arm section (8a2, 8b2) arranged at the opposite end of the first lever arm section (8a1, 8b1). The first of the lever arm sections (8a1, 8b1) lies in the stroke range of the hollow body (7) that can be filled with fluid and the second of the lever arm sections (8a2, 8b2) cooperates with a side part (5a, 5b). |
