Electrical device, in particular steering column switch for automotive

Vehicle door locking system

In vehicular electric door lock arrangement the running time of a first adjusting unit is longer than the worst possible running times of the other adjusting units. The first adjusting unit operates a switching unit via which the running time of the other adjusting units is preset. The separate timing element for the control of the various adjusting units used in prior systems can be omitted, because this timing function is provided by one of the adjusting units.

Adjusting device, especially for locking and unlocking motor vehicle

A drive unit for adjusting window panes, sunroofs, and seats in a vehicle has a reversible electric motor behind which is inserted a worm gear with a worm shaft. To prevent an undesired or unauthorized adjustment of a motor vehicle part, a brake device is provided. The brake device has a mechanical, one-way brake element with which the worm shaft may be coupled by an axial displacement. In order to reduce the effect of the brake device on the worm shaft when the window pane is adjusted by the electric motor, the brake element is the rotatable part of a rotation limiting device and, in the axial direction, it is supported on a stop.

In a tire pressure monitoring device for motor vehicles the electric signal of the pressure sensor is galvanically transmitted directly via the outer ring, the rolling bodies and the inner ring of a rolling bearing carrying the rotating wheel. The signal transmission is effected via leads and contact connections automatically opened when the wheel is demounted and automatically closed when the wheel is mounted. The inflation pressure is also conducted via a rolling bearing developed as a sealed unit in order to remote-adjust the tire pressure en route.

A motor driven window regulator combined with a door lock for a motor vehicle. A reversible motor is used to drive a sector gear. The sector gear in turn rotates a gear to pivot a lever to raise and lower the window. An engaging clutch pivoted to the free end of the lever is used to couple and decouple the mechanism to the window.

Window lifter and door locking device

A circuit arrangement for a reversible electric motor supplied from a voltage source, which motor drives a combined window-lifter and door-locking installation in motor vehicles. The motor is switched on by way of a first operating switch developed as a reversing switch and by way of a second operating switch serving as a central switch. A position switch is assigned to the motor and is developed as a two-way switch which is operated by the motor. When the window is completely closed, the position switch may be changed over from a first switching position into a second switching position and after an unlocking operation, or before the window is opened, the position switch may again be changed over from the second switching position into the first one. During a locking operation the second input of the position switch is applied to a pole of the voltage source other than the pole used during the other adjusting operations.

Window lifter and door locking system

A synchronizing circuit for a combination window and door locking system for automotive vehicles. During normal operation the door's are locked and unlocked by continued rotation of the window lifter motor. If the door locks have been manually operated between motorized operations, the locked and unlocked positions of the door locks can become out of synchronization with one another. The synchronization circuit utilizes and interconnected series of switches, position-sensitive switches and relays to control the window lifter motors. During a locking operation, the circuit automatically sequences the lifter motors first through an unlocking operation and then into their door locking positions.

Window and door locking system for vehicles

A combination power window and power door locking device for use in an automotive vehicle door. The locking of the door is accomplished by rotatably mounting the common motor in the door and resiliently urged toward an angular stop position. After the window pane is in one of its end positions, continued application of external power to the motor rotates the motor away from the stop position to activate the door locking mechanism.

Door locking device

A circuit arrangement for a wiper motor, of the type comprising a controllable switching element for switching a motor operating circuit, wherein the switching element is controllable by a manually actuable operating switch and by a disconnection signal of a limit switch. The disconnection signal of the limit switch is directly conducted to the switching element through the motor supply lead itself. Thus, an inexpensive single-conductor cabling arrangement is realized.
