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.

Electrical circuit having a multilayer printed circuit board

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

Locking device for a motor vehicle having a number of doors

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.

Drive device having an actuating drive

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

Electronic central locking system

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.

Electric center for motor vehicles

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.
