Abstract
Abstract A head restraint for seats with a seat back with an upper support body (1) which is provided in the extension of the seat back (3) above the upper edge (2) of the seat back (3) at head height, and with the longitudinal axis (6) aligned horizontally and parallel to the longitudinal axis (7) of the seat back (3), whereby the underside of the upper support body (1) is in contact with, or spaced apart from, the upper edge (2) of the seat back (3). At least two horizontally spaced apart structures (5) for lateral support of the head are provided at the front (9) of the upper support body (1) and/or integrated into it. At the height of the cervical lordosis of a seated person a lower, essentially cylindrical support body (4) for supporting the cervical spine is attached; when viewed from the side, the cross-section of the said support body (4) is essentially round, oval, elongated or semicircular in shape, and the longitudinal axis (13) of the said support body (4) is aligned horizontally and parallel to the longitudinal axis (6) of the upper support body (1).
