The invention provides a testable foil pressure sensor constructed of two carrier foils which are laminated together. The first carrier foil is coated with a semiconductor material, while the second carrier foil has two adjacent strip conductors which can each be bonded on both ends and which, within spatially bounded areas which form sensor elements, have &ldquo;comb&rdquo; structures, with individual fingers which mesh with one another in a no-contact manner. According to the invention, within a sensor element, at least one of the contact fingers of the comb structure is formed by a strip conductor loop and at least one other contact finger is formed by a stub line branching off a strip conductor.

A device for detection of trapping in a power-operated closing element with a switching element, which is arranged along a first closing edge within an elastic hollow section. The hollow section includes a central area extending longitudinally, in which an active area of the switching element is arranged, and at least one side area extending longitudinally, in which a non-active edge area of the switching element is arranged. The side area has a higher deformability on the side of the hollow section facing the first closing edge than on the central area. The device has a force transmitter extending longitudinally, which transmits a trapping force from the side facing away from the first closing edge to the side area of the hollow section.

A cover of an openable motor vehicle roof includes a cover plate which is surrounded by a plastic frame formed by foaming or injection, and which connects at least one attachment part to the cover plate. The plastic frame includes at least one sensor element which is located on one wall of the attachment part and which signals pinching of a body part or article when the closes on an object by partial deformation of the plastic frame.

A cover (2) of an openable motor vehicle roof (1) has a cover plate (3) which is surrounded in at least one edge area by a foamed-on or injected-on plastic frame (4) which, at the same time, is used to connect at least one attachment part (inside cover sheet 6) of the cover. At least one sensor element (8) is integrated into the plastic frame (4) and it signals pinching of a body part or an article (11) by means of partial deformation of the plastic frame (4) when cover (2) is closed.

A servo-drive device is provided for an actuating of, for example, ventilation dampers in motor-vehicle air-conditioning installations element which can be stably positioned in a plurality of positions, d.c. motors with a gear mechanism are used for servo-drive devices of this type. A mechanical system which is moved at the same time and has potential energy varying along its path of movement is coupled to the servo drive such that it influences the current of the servo motor to permit the respective position of the actuating element to be identified by a control device on the basis of the evaluation of the motor current characteristically which depends on the force exerted by the mechanical system on the actuating element.

A device for detecting seat occupancy in a motor vehicle, especially for inhibiting airbag release when a seat is unoccupied, is provided. A seat occupancy sensor has a front sensing region and a rear sensing region, which can be evaluated separately. In this way, it is possible to determine whether the front seat passenger is in a sitting position close to the front seat edge of the seat cushion, which reduces the protective effect of the airbag. This can possibly be indicated visually or audibly. As a further measure, the inhibiting of an airbag release can be provided in the case of an incorrect sitting position. The seat occupancy sensor can be a resistive membrane pressure sensor.

A method and device for controlling vehicle interior lighting as a function of certain lighting-relevant states, in which the respective turning-on or turning-off process takes place with dimming. The dimming parameters, such as turning-on or turning-off dimming time or desired final brightness, are selected in advance as a function of the vehicle state that activated the control process, which permits a highly variable and situation-specific lighting control. The lighting control unit, depending on signals from a sensor group and according to a program stored in a program memory, controls a lighting device through a controllable switch.

The invention relates to an apparatus for interrupting the closing operation of an electric motor driven movable closing element, such as a vehicle sunroof when an obstacle which obstructs the closing operation is detected. A pressure-sensitive sensor strip is arranged on the closing edge of the moved closing part and the sensor signal is transmitted in accordance with the transponder principle by an attenuation modulation of an electromagnetic alternating field. The wireless sensor signal which is thus transmitted controls the control device for the electric drive of the closing part. When an obstacle is detected, the drive is switched off or reversed, depending on the sensed pressure applied to the sensor strip. The sensor strip is preferably implemented by a resistive foil pressure sensor.

A device for recognizing a child's seat which is strapped to the front passenger's seat of a motor vehicle is provided. Such a device is required in order to inhibit release of a front seat passenger's side airbag when a child's seat is strapped on the front passenger's seat. An identification carrier, for example, an electrical tuned circuit or an intelligent data carrier, which attenuates an electromagnetic measurement field in a characteristic manner, is fitted to the child's seat. The presence and, possibly, also the type of child's seat used can be recorded.

An igniting device for protective devices in vehicles has a pyro-electric igniting element which is associated with an electronic lock and a controlled switch for releasing the application of current to the igniter, and can be combined in an integral component. The application of an igniting signal leads to current being applied to the igniting element only after transmission of an unlocking signal to reliably prevent an unwanted triggering of ignition, for example by accidental application of an external voltage to the connections of the igniting device. The reactive igniting substance can be directly connected to a silicon chip which monolithically implements the electronic lock and the controlled switch.
