The invention pertains to a device for acquiring signals from sensors () installed in a motor vehicle, where at least two sensors, which are connected by electrical conductors to a source of electrical voltage () and to an evaluation unit (), are mounted in different positions in the vehicle. To simplify the installation of the device, the sensors () are attached a certain distance apart to a common ribbon cable () with parallel electrical conductors, which cable has at least one conductor which can be connected to the voltage source () to supply power to the sensors () and several signal conductors, which can be connected to the evaluation unit () and possibly also to the voltage source (), the number of which corresponds to the number of sensors to be connected. All of the sensors () are connected to the power-supply conductor, and each one is connected individually to one of the signal conductors.

Device for acquiring signals from sensors installed in a motor vehicle

Apparatus for signal and current transmission between end points capable of moving relative to one another having a flat ribbon line arranged in between. The ribbon has at least two conductors, embedded in an insulating sheath. The ribbon is subdivided into winding areas, connected by a U-shaped reversal point and is accommodated in a cassette, having a rotor and stator. The rotor and stator enclose between them an annular winding area for the ribbon. A strip of insulating material is arranged in the winding area of the cassette and has at least two sections which are offset with respect to one another in the circumferential direction of the cassette and have reversal points and associated winding areas. The strip is placed around turning points, fitted to the stator. The strip supports the ribbon such that turns of the ribbon do not fall on one another.

Apparatus for signal and current transmission between end points which can move relative to one another

An arrangement for supplying power to loads provided in a motor vehicle, in which at least two units of electrical lines are combined, is disclosed. The lines are connected to both a voltage source and a load at each end. The loads are provided both on the body of the motor vehicle and on at least one pivoting part, such as a door. A contact carrier having a number of contact elements, which are isolated from one another and are made from a conductive and resilient material, is provided in the region of the axis of rotation, it being possible for this contact carrier to follow a pivoting movement of the moving part, while maintaining the electrical connection between the voltage source and the loads. The wire shaped contact elements are designed as helices having at least one turn, and have mating contacts on each end.

Arrangement for supplying power to loads which are provided in a motor vehicle

A signal transmission arrangement is proposed wherein the transmitter has an electronic circuit that can be connected to an electrical voltage source, and the electronic circuit, via electrical wires () connected thereto, can be connected with the voltage source and the control unit of the transmitter. The arrangement further has a metallic plate () made of an electrically conducting material, which is associated with the circuit and acts as a sensor. This electronic circuit is arranged in a moisture-tight way in a plastic housing (G) into which the lines () are run in a moisture-tight manner. The plate () is arranged in an outwardly open cavity located in a wall of the housing (G) and its outer flat surface is covered in a moisture-tight manner by a layer () of flexible insulating material that fits tightly and without any gaps against the plate ().
