    摘要： A regulator with a hysteresis-affected characteristic curve has a manually operable actuating element for presetting a desired control variable, an axially displaceable control slide for adjusting the preset control variable and a control incline which is coupled to the actuating element. The control incline converts, by means of a rising control face, the adjustment movement of the actuating element into a axial displacement of the control slide. For the purpose of compensating the hysteresis when adjusting a control a variable such that the same control variable is brought about by rotating the actuating element to the left or to the right into the same setting, the control incline bears a toothing along its control face. Each tooth has, in two planes which extend along the displacement direction of the control face and are perpendicular to one another, a sawtooth-like contour with in each case a rising edge for running up the control slide and a falling edge which follows in the displacement direction. Each tooth contour is associated with one of the two displacement directions. Each tooth contour is associated with one of the two displacement direction of the control incline and deflects the control slide in the axial direction or transversely thereto.

    摘要： A pressure regulator whose initial pressure can be set by manually setting the initial stress of a control spring has a double-seated valve with an inner and outer valve seat and a valve closing element. The valve closing element divides a supply pressure chamber from a control pressure chamber and the latter from a pressure-relief chamber. The inner valve seat is arranged on a control piston which is loaded by the control spring. In order to set a higher initial pressure, the initial stress of the control spring is increased, in order to reduce pressure, the initial stress of the spring is diminished. During this process, the outer or inner valve seat lifts off temporarily from the valve closing element until equilibrium is reestablished by a corresponding pressure chamber and the double-seated valve closes. In order to compensate the hysteresis occurring here, a lifting device is provided which, when the initial stress of the control spring is reduced, briefly lifts off the inner valve seat from the valve closing element and then becomes inactive again. The superproportional pressure drop associated with this in the control pressure chamber has the effect that the equilibrium of forces for closing the double-seated valve is always produced after the outer valve seat is opened by the pressure increase.

    摘要： A motor vehicle seat with a backrest contains a spring core and has forwardly curved side parts into which inflatable air cushions are inserted for varying the contour of the backrest. The air cushions are arranged between fixed uprights and the spring core. As a result, in the event of variations in the filling pressure in the air cushions the overall shape of the spring core is varied. The horizontal contour of the backrest can thus be varied to a greater degree than previously with air cushions in the upholstery, without the surface hardness of the upholstery being adversely affected.

    摘要： A headrest for a vehicle seat having a backrest is provided which has a head cushion fastened to two supporting rods and two side pieces which are integrated in the head cushion. In the in-use position, the side pieces project laterally on the head cushion beyond its cushion front and, in the not-in-use position are accommodated inside the contour of the head cushion. For implementing a headrest of a compact minimum size and an aesthetically attractive shape which optimally meets the demands made on a headrest with respect to the driving operation and the resting phase, each side piece is swivellably disposed on a vertical tube section which, in turn, is fastened on a supporting rod so that it can be swivelled about a swivel shaft extending transversely thereto. Using an upper and lower cross traverse, the two tube sections are fixedly connected with one another and each carry a cushion enlargement of the head cushion. The side pieces are constructed in such a manner using a parallelepiped-shaped basic cushion body and a padded wedge piece continuing therefrom in one piece that, in their not-in-use position, they cover one another and end flush with the front and rear side of the cushion enlargements.
