Abstract: A ventilation-heating apparatus comprises a fresh air passage with which a fresh air ventilation mechanism is associated and which opens into a room-side inflow air supply opening. The ventilation-heating apparatus further comprises a room air passage with which a room air ventilation mechanism is associated and which opens into a room-side air removal outlet opening. Fresh air and room air passages are passed through a heat exchanger which is suitable for the transfer of heat from the room air passage to the fresh air passage. An electrically heatable metallic heating element is provided in the region of the fresh air passage. A suitable heat storage element is associated with the heating element for the storage of the heat produced. An electrically heatable metallic additional heating element which can be selectively switched on is provided in the region of the fresh air passage.

Abstract: In order to make an apparatus for attenuating the pivotal or sliding movement of motor-vehicle parts which is formed of a first part fixed on the nonsliding or nonpivoting part and a second part mounted on the pivotal or slidable part which is extremely inexpensive and which takes up minimal space it is suggested that one of the two elements be formed by a tubular and stiff or flexible tube which is filled with a viscous mass and that the other part being formed by a core which slides in the tubular body so that relative pivoting or sliding of the parts coaxially slides the core relative to the tubular body.

Abstract: A handle in a motor vehicle has a grip element that can be manually swivelled about a grip element axis from a home position. The handle may be moved back into the home position by spring tension. An attenuation device has an element which can rotate around the grip element axis on which a braking factor is exerted by a viscous material when moving back into the home position.

Abstract: A height adjuster for a vehicle safety belt with an adjusting element features two gears that can rotate on the adjusting element. The gears are braced against two support points in two opposing denticulations of a guide rail essentially symmetrical to a longitudinal middle plane running in the longitudinal direction of the guide rail. A catch element engages adjustably, in the longitudinal middle plane, with the denticulations of the two gears.

Abstract: A motor-vehicle head rest has a one-piece plastic body formed with a pair of like recesses opening parallel to each other, and respective pivot assemblies in each recess. Each such pivot assembly has a holder and a pivot element held in the holder. Interengaging formations on the body and holder retain the holders in the recesses, and respective rods engage up through the pivot elements of the assemblies. Such a head rest is made by fitting the holders to the respective pivot elements, engaging the holders carrying the respective pivot elements into the respective recesses and thereby interengaging the formations and locking the holders with their pivot elements in the respective recesses, and fitting the rods through the pivot elements.

Abstract: A headrest assembly used in a motor-vehicle seat formed with an upwardly open recess has a pair of complementary housing shells having mating annular edges that meet and are joined together substantially on an upright plane to form a cavity. Each shell is formed with a pair of seat halves open at the plane and forming with the seat halves of the other shell a pair of seats aligned along a horizontal axis and lying on the plane. The joined shells are set and secured in the recess of the seat. Respective pivot bodies in the cavity engaged in the seats are pivotal therein about the axis between upright and horizontal positions. Respective support rods extend radially from the pivot bodies out of the cavity and a headrest is fixed on the support rods outside the cavity.

Abstract: An arrangement for adjusting the distribution of pressure on a support plate in a backrest of a vehicle seat for vertebral support, wherein a pressure-distribution element which is adjustable in respect of height and which is in the form of a rolling carriage assembly is disposed between the support plate and a pressure plate.

Abstract: A safety belt system for a motor vehicle includes a safety belt that is stored in a belt storage unit, a belt reversing point, a carrier that is fastened on a part of the motor vehicle body, an adjusting part that carries the belt reversing point and is arranged on the carrier such that it may be displaced and locked in different positions, and a clamping device. The clamping device is fastened onto the carrier in such a way that forces that originate from the safety belt while the safety belt is clamped in the clamping device and act at the fastening point of the clamping device and the locking position of the adjusting part are directed opposite to one another.
