Abstract: An outside door handle includes a handle and a switching component which is coupled to the handle in such a manner that, when there is an opening force which acts in a correct manner on the handle in order to open it, the switching component automatically responds and generates a switching signal. Operating convenience may be achieved by a response threshold of the switching component selected to be at such a low level that the switching component responds even before the opening force overcomes a restoring force counteracting it and prestressing the handle into an unactuated starting position.

Abstract: In said devices the operation of the handle serves to open the door when the lock is in the unlocked position. The handle operation is achieved by means of an operating lever (30) and the rotation of the lock cylinder (60) is transferred to a carrier (45). According to the invention, the construction may be simplified and rendered flexible, whereby a control member (50) is used, which transmits the movement of the carrier (45) to the operating lever (30) of the handle. The operating lever (30) has an adjustable bearing position (31, 11 or 32, 12), which is determined in relation to the rotational position of the lock cylinder (60) by the control member (50). The transfer ratios (34.1 to 33.1 or 34.2 to 33.2) on the operating lever (30) are thus altered relative to a connector (40) leading to the lock. Although an identical operation of the handle occurs, differing working strokes (36) occur at the connector (40).

A vent channel is provided which selectively connects the working chamber with the atmosphere as a function of the position of a movable closing element of the drive unit element and contact of the control member with the vehicle body part such that when the body part is closed after a partial opening, the drive unit is ready for another control operation.

Abstract: The invention provides a key/vehicle communication device in which an electronic key capable of being inserted into a steering-column lock controls activation of an immobilizing device having an inductive key/steering-column lock communication channel for recognizing whether a key authorized for use is inserted. A key/vehicle communication channel is also provided, for the remotely controllable activation of at least one vehicle-side function via a key-side actuating member. A vehicle-side control unit determines, via the inductive key/steering-column lock communication channel, whether a key authorizing the driving of a vehicle is inserted in the steering-column lock and, if so, blocks the vehicle-side part of the key/vehicle communication channel.

Abstract: An operating system for hydraulic drive elements of a folding top, such as a lowerable folding top of a convertible, can be actuated by switching apparatus. The drive elements are fed by a pressure source from a pressure medium reservoir via an inlet and connected to a return to the pressure medium reservoir. Switchable directional control valves distribute the pressure generated by the pressure source to the drive elements moving various parts. Actuation of the directional control valves corresponds to a given sequence of movements of the top. To simplify the operating system, a plurality of operational elements assigned to various operating functions can be switched at the same time by individual directional control valves. As a result, a smaller number of expensive directional control valves is required.

Abstract: Apparatus for controlling and adjusting an arbitrary number of adjustment units for a motor vehicle includes an electro-pneumatic bus to which are connected in arbitrary sequence, both electrically and pneumatically, all the pertinent adjusting units. The electro-pneumatic bus is composed of at least one pneumatic adjustment pressure line and of at least one electric control signal line which may contain several conductors. While reference data from a central control electronics are applied through the electric control signal line of the electro-pneumatic bus, the individual adjusting units are connected through associated valves in the pneumatic system to the pneumatic adjustment pressure line of the electro-pneumatic bus. The adjusting units preferably are designed to be modular control loops. As a result the pneumatically driven adjusting members units not only two positions, but also they may be set and controlled in quasi-analogue manner.

Abstract: A locking-aid device is disclosed for a lock, especially for a vehicle door lock or flap lock, in which a pneumatic single-acting locking-aid drive is provided for displacing an abutment for a rotary latch out of a catch position into a locking position, in which the abutment is secured positively by means of a detent pawl. According to the invention the detent pawl can be lifted out, during the opening of the lock, independently of a movement of the locking-aid drive by means of an operative connection. This can be brought about purely mechanically or by means of a separate drive for lifting out the detent pawl during the opening of the lock, so that the abutment can always jump into its catch position immediately during or after the opening of the lock and thus also allows a successive multiple activation of the locking-aid assistance.

Abstract: The present invention provides a method of operating a hand-held transmitter for controlling vehicle functions. The hand-held transmitter has the ability to emit output signals for controlling both locking devices and drives for closing vehicle openings. A hand-held transmitter emits the output signals for controlling locking devices at a first output power and range and emits output signals for controlling the drives at a second output power and range. The second output power and range are lower than the first output power and range.

Abstract: A remote control system has a transmitter, a current storage device feeding its triggerable control signals, an external receptacle into which the transmitter can be inserted, and a charge monitoring device with charge-state indicator. The charge monitoring device with charge-state indicator is assigned to the receptacle and preferably causes the transmitter to automatically transmit a control signal after being inserted into the receptacle. Via the charge monitoring device, the charge state of the transmitter can be evaluated independently of the voltage supply from the current storage device of the transmitter either directly via its voltage supplied under load or indirectly via the intensity of the control signal emitted by it, and be indicated if respective minimum values are undershot. The system is suitable for remotely controlling motor-vehicle security devices.
