Abstract: A head rest is illustrated and described that has a head box (11) by which at least one support rod (12) can be secured to a vehicle seat, wherein at least one end of the support rod (12) is received in a bearing (14) carried on the head box (11) or the vehicle seat, wherein the support rod (12) can be latched releasably to at least one bearing (14) by a latch (15) movable between a latching position and a release position, wherein the latch (15) has at least one notch (16) that extends over a region of the circumference of the support rod (12) and has a latch element (17) carried by the bearing (14). The special feature is that the latch element (17) is movably mounted, so that in the latching position, in the event of a relative rotation between the support rod (12) and the bearing (14), it is movable out of a starting position into at least one crash position.

Abstract: The invention relates to a headrest (10) for a motor-vehicle seat that is fixed on the backrest of a vehicle seat by means of at least one support rod and that has a head cushion (13), the headrest being provided with a base element (15) on which the support rod (11) is provided. Object of the invention is to provide a headrest (10) that allows movable adaptation to the adjustment and equipment requirements of the individual vehicle types. A solution to this object is provided by the fact that the base element (15) has holding means (16, 17, 18, 23, 32, 33, 44) that are independent of each other and can be optionally used in a module-like manner for a respective application which allow the mounting of supporting elements for the connecting element (11a, 11b) as well as the mounting of adjusting elements (22, 34, 35), in particular for the vertical, horizontal and angle adjustment.

Abstract: There is disclosed a direction-changing roller for suspension frames of photographic material developing machines, over which the photographic material to be developed is guided in a meandering path. The roller has a cylindrical roller body on each end of which there is arranged a respective collar-shaped flange. There are further rollers inserted in the roller body. The surfaces of the further rollers are flush with the outline or surface of the roller body. Each further roller is mounted to be freely rotatable about an axis extending perpendicular to the axis of rotation of the direction-changing roller and radially offset from this axis of rotation.
