<p>A headrest for automotive vehicle seats has, for receiving in each case one supporting rod (11), two seat sheaths (10) which are held in frame-side through-openings of a backrest and are made of injection moulded plastic. Each seat sheath (10) has an upper collar (13) which is fitted onto the upper side of the backrest and a tube area (29) which adjoins it at the bottom and is closed on the circumferential side, and a lower holding area (17) which adjoins the said tube area (29) and forms two diametrically opposite axial slits. The holding area (17) has, on the outside, two catch projections (18) which lie opposite one another and can be expanded in the manner of a wall plug by inserting the supporting rod (11) and can be locked to the frame. It is possible to obtain a simple shape of the tool for producing seat sheaths by virtue of the fact that the holding area (17) has a baseplate (19) which is arranged approximately tangentially with respect to the tube area (29) and extends downwards from the said area (29), two side walls (15, 16) and other wall components (13, 25, 28) protruding freely forward, at a radial distance from one another, from the said baseplate (19) and all the lateral areas of the said wall parts (13, 25, 28) are located perpendicularly on a common plane. Narrow surface areas facing away from the baseplate (19) bound the one axial slit. The baseplate (19) forms the other axial slit which is open towards its lower end. The catch projections (18) are arranged on the outside on the side walls (15, 16). <IMAGE></p> |
