A method for operating electrical drive units of seat components in a motor vehicle during a detected pre-crash situation. The method moves a passenger to a target position for an impending crash based on an actual position of the passenger. The method also determines a control strategy for coordinating an adjustment of the seat components in order to actuate at least two of the drive units simultaneously or immediately successively such that the required power of the drive units is minimized.

Method for operating electrical drive units of seat components in a motor vehicle, preferably in a pre-crash case, and system for performing the method

The invention relates to a pneumatic open- and closed-loop control apparatus () for flows of pressure fluid, having one inlet conduit (), two outlet conduits (), and one venting conduit (), and also having a valve piston () mediating between these conduits and mounted in a valve chamber (), and to a method for open- and closed-loop control of flows of pressure fluid. It is proposed that by means of a pneumatically driven valve piston (), with a predeterminable time constant, one outlet conduit () each of the pneumatic open- and closed-loop control apparatus () is connected to the single inlet conduit (), while the other outlet conduit is simultaneously connected to the venting conduit ().

The invention relates to an electromagnetically actuatable valve that has a magnet part, a moveable armature element, a spring element, and a valve part. The magnet part has at least one coil form with a magnetic coil wound on it, a flux concentrating element and a center pole. The valve part has a closing element that cooperates with the armature element and controls the opening and closing of the valve on a valve seat. The armature element is designed as a clapper-type armature and cooperates with the center pole by way of a damping element.

The invention creates a vehicle pneumatics overpressure regulating circuit of a supply device of a pneumatic consumer in a vehicle with an operating pressure. The overpressure circuit has a compressed air source , which furnishes compressed air for the consumer ; a pressure switch , by means of which the compressed air source is turned on and/or off to supply the consumer with compressed air; and a supply line , by way of which compressed air can be carried from the compressed air source to the consumer . The pressure switch can be subjected to a measured pressure via a pneumatic measurement line , which is separate from the supply line, and this measured pressure characterizes a state of the operating pressure of the consumer. As a result, extremely precise regulation of the requisite operating pressure is successfully achieved.
