Abstract: An electrical circuit includes a multilayer printed circuit board and a housing which shields against electromagnetic interference. A portion of at least one outer layer of the printed circuit board are in the form of contact areas which are connected to a respective conductor area on a further layer of the printed circuit board. The conductor area occupies an area region that is offset with respect to the contact area and forms a bushing capacitor with a ground area of the outer layer.

Abstract: A locking device for a coach (13) has a control device (20) for detecting a position of a portable transmitter (21). The control device (20) drives, in dependence on the position of the transmitter (21), locks (24, 25) that locks doors (22, 23) of the coach (13) which are provided exclusively for this position. As a result of this, unrequired doors (22, 23) do not have to be monitored.

Abstract: The invention relates to a locking device, in particular for vehicle doors, having lock elements such as a rotary latch and locking pawl, at least one lock element being brought from a locked position into an unlocked position at least as a function of the operation of a handle, said locking device being defined by manually operated means with which the at least one lock element can be brought from the unlocked position into the locked position, the means not being formed as a lock cylinder to be operated with a key.

Abstract: A drive device, in particular a locking device, having an actuating drive for driving a moving element as well as a position detection device for detecting the position of the moving element, in which case the invention provides that the position detection device has a magnet element which is fitted to the moving element, as well as a Hall element which is arranged in the vicinity of the magnet element, in which case the Hall element is integrated in an electronic module.

Abstract: The security to prevent theft of a central locking system for motor vehicles is improved by arranging a switch 34, 340, which can be switched by a coded signal, in the supply voltage lines 31 and/or 310 and/or 32 for driving an-actuating element.

Abstract: An electric center for motor vehicles has an electric part by which different electric power levels are connected to each other. The electric center is arranged on an insulating part holder, and connectors of the electric part engage into the insulating part holder. In order to assure a compact electric center for motor vehicles which is insensitive to disturbance, at least one connector of the electric part which is acted on with a higher power is contacted by a current feed on the side of the part holder facing away from the part holder. At least one low-load connector of the electronic component is connected with a holder member bearing electronic components, the holder member being physically separated from the insulating part holder.

Abstract: In an apparatus for the unlocking of doors of a motor vehicle in the event of an accident, at least one device for tensioning a safety belt is, in the case of an accident, operatively connected with at least one door-unlocking device. Operation of the belt tensioning device during an accident initiates operation of the door unlocking mechanism.

Abstract: A device for driving a motor-operated closure part for an opening, especially on a motor vehicle, having a protective circuit for interrupting the closing movement when there is an indication that an object may be obstructing closure of the opening. A speed transmitting means exists that detects the adjusting speed of the closing part on at least one range of the adjusting path of the closure part that is critical with respect to the engagement of an obstruction. In addition, an evaluating stage is provided that responds to the speed signal and/or its rate of change with respect to time, for producing an obstruction signal that activates a control means of the circuit to interrupt the closing movement.

Abstract: An operating system for movable parts for the selective closing or exposing of openings, especially for sliding roofs and sliding/lifting roofs of motor vehicles. The operating mechanism has a motor drive for the movable part and an actuating member for starting the drive, if required. In order to facilitate, especially, the bringing of the movable part into intermediate positions, the actuating member is developed as a desired-value transmitter for the position of the movable part, and the drive is part of a control circuit which compares the position selected at the desired-value transmitter with the actual position of the movable part and adjusts the movable part until the deviation has become zero.
