Abstract: A head protection system for occupants of a motor vehicle has a multi-chamber air bag, which is inflated laterally of the head in the event of a side impact and prevents the displacement of the head. In addition, it protects the head from vehicle body parts that penetrate the occupant department. Via the individual chambers, an L-shape of the air bag can be constructed which is optimal for the desired purpose. In addition, the division into several chambers permits longer and therefore less aggressive inflation times.

Abstract: A device for operating a windshield wiper with an automatic wiper control. The wiping operation is optimally adapted to the wetting conditions of a windshield as soon as the automatic wiper control is turned on. This is achieved by a control stage which, during the switching on, triggers at least one initial wiping action when responding to an activation signal emitted by an input stage. Following the initial wiping action, the wiping operation takes place on the basis of the wetting conditions detected by the sensor unit.

Abstract: The invention relates to an apparatus for operating a windshield wiper, having a sensor device for detecting the state of wetness of a windshield, an evaluation device that receives the sensor signal and an actuating unit for the windshield wiper that can be actuated by the evaluation device to effect suitable wiping operation. Even when individual drops impact the windshield, appropriate wiping operation can be initiated during a drying phase of the windshield, because it is provided that current measured values of the sensor signal can be supplied to both the difference-initiating stage and a drop-recognition device that is provided in the evaluation device and in which the sensor signal can be evaluated with respect to individual drops using signal breaks, and that an adapted control signal can be generated by the control-signal-generating stage when a minimum signal break is detected, with which signal corresponding wiping operation can be initiated by way of the actuating unit.

Abstract: A device for operating a windshield wiper with an automatic wiper control. A fast reaction to a suddenly occurring heavy wetting event is assured without adversely affecting the sequence of intermittent wiper operation. This is achieved by an evaluation unit which has a surge detection stage that makes it possible to detect, during intermittent operation when a sensor signal falls short of a surge threshold and by triggering a control signal for at least one wiping action when the signal falls short of the surge threshold.

Abstract: A arrangement for operating a windshield wiper in a direct mode, an intermittent mode or a continuous mode, having a sensor device for detecting a degree of moisture on the windshield, an evaluation device for the sensor signal and an actuation unit for the windshield wiper. A non-disturbing smoothing of the interval times is accomplished in a simple manner in that an interval time control has a smoothing stage for the interval time with which it can be determined during which time segment of predetermined time segments within the interval time a wetting event occurs, starting from the beginning of the interval, and with which the second interval time can be shortened all the more, the earlier the time segment appears during which the wetting event occurs.

Abstract: The invention relates to an apparatus for operating a windshield wiper, having a sensor device for detecting the state of wetness of the windshield, an evaluating device that receives the sensor signal and in which an adjusting device is provided for updating a reference value, and an actuator unit for the windshield wiper that is actuated by the evaluating device for initiating a wiping process if the difference between the reference value and a current measured value exceeds a predetermined threshold value. The evaluation and analysis of an event that influences the sensor signal, such as a slow buildup on the windshield under drizzly or foggy conditions, are facilitated by the fact that the adjusting device includes at least one adjusting stage whose time constant is in an order of magnitude of one second to a few seconds, and that the reference value can be followed step-wise, taking into consideration all current measured values received at intervals of fractions of a second.

Abstract: The invention relates to an arrangement for the automatic operation of a windshield wiper, having a sensor device for detecting the degree of moisture on a windshield, an evaluation device, and an actuation unit for the windshield wiper which is actuated by the evaluation device. The degree of moisture on the windshield can be analyzed better in that the evaluation device in has a recognition stage for recognizing drying moisture that is present on the windshield. By means of this recognition stage, whether the level of the measured values is rising as a result of the drying process can be determined from a time sequence of measured values derived from the sensor signal. In this manner, unnecessary wiping actions can be prevented.

Abstract: An apparatus for operating a windshield wiper having a sensor device for determining the state of wetness of a windshield, an evaluation device which receives the sensor signal, a dirt-recognition stage and an adjusting device for updating a reference value when dirt is present on the windshield, and an actuating unit for the windshield wiper which can be actuated by the evaluation device in order to initiate a wiping process if the difference between the reference value and a current measured value of the sensor signal exceeds a predetermined threshold value. The measured values can be evaluated by the dirt-recognition stage with respect to signal breaks of the sensor signal caused by the wiping action of the wiper across the sensor surface.
