Abstract: A motor vehicle seat, in particular for an open motorcar, having an air supply device for supplying an air flow from an air output opening to the head, neck and shoulder area of a passenger. The air supply device includes a heating or cooling system for heating or cooling the air flow. This air supply device is a more efficient heating or cooling system for a motor vehicle seat. For this purpose, the air supply device comprises a sandwich that includes at least one heating or cooling layer and at least one air penetrable layer and a structure which makes it possible to convert the air flow into turbulent or diffused steam.

Abstract: An optical device for use under significantly varying ambient pressure is provided comprising a housing, a transparent element, a first sealing device and a protection apparatus. The housing has an interior part, an environment outside the housing and a recess in a first region. The transparent element is arranged in the first region in a region of the recess. The first sealing device is sealing a first sealing gap between the transparent element and the housing. Furthermore, the first sealing device is sealing the interior part of the housing relative to the environment of the housing up to a first pressure level. The protection apparatus is arranged outside the housing and is displaceable from a first functional position into a second functional position.

Abstract: The headrest (10), in particular for a vehicle, comprises a support element (14) integrated in a foam body (12). Here the support element (14) has a seat (16) for stabilizing the position of a foaming tool (20) extending into the headrest interior (18) during manufacture of the headrest. A foaming tool for the foaming of a corresponding headrest is furthermore proposed, the foaming tool (20) having a filling part (34), joined to which is a transfer part (36), which at the end extends into an outlet element (38). The transfer part (36) has a stabilizing part (40), which can be operatively connected to the seat (16) in the support element (14) of the headrest (10).

Abstract: A cup holder includes a housing, a holding member having an opening, a connecting element, and a tray. When not in use, the holding member, the connecting element and the tray can be sunk in the housing, and can be extracted from the housing in the operative position. The tray can be arranged at a distance parallel to the holding member. One end of the connecting element is connected by way of a first swivel joint to the holding member, and the other end is pivot-connected to the tray by way of a second swivel joint. The second swivel joint is arranged at a distance from the center of mass of the tray so that the gravitational force produces a torque, by which the tray folds out.

Abstract: An operating system is used for hydraulic convertible top locking systems in retractable roof convertibles. A control unit has a control piston which is loaded in one axial direction by the hydraulic driving unit and in the opposite axial direction by a mechanical pressure spring arrangement. The control piston is restrictedly guided in the circumferential and axial direction in a housing by a control contour.
