The invention relates to known housing seals of two housing parts lying against each other, a first housing part () having a first sealing surface () and a second housing part () having a second sealing surface (), which housing seals are equipped with a seal (), which is inserted into a groove () in the first sealing surface () of the first housing part (), wherein the groove () is covered by the second sealing surface () of the second housing part (). According to the invention, in order to prevent crevice corrosion, the groove () has an opening () between the sealing surfaces (), which is used to ventilate the groove () having the inserted seal. The invention is intended for water pumps, in particular for auxiliary water pumps of motor vehicles.

The invention relates to a device for adjusting a vehicle seat, the frame structure () of which can be adjusted using drive motors () having presupported gear units (), and the vehicle seat is accommodated on two seat rails () arranged parallel to each other. The frame structure () of the vehicle seat can be adjusted spherically using lifting elements () in two planes separated from each other.

Device and method for adjusting seats in vehicles

The invention relates to a device for adjusting a seat back ( ) of a vehicle seat ( ), in which a drive ( ) that carries out adjusting processes is integrated. This acts on stagger gears ( ), with which the seat back ( ) is moved within a range of inclination ( ). A torsion element ( ) is provided between the stagger gears ( ) that compensates the clearance in the stagger gears ( ) within a first range of adjustment ( ) of the seat back ( ) and functions as support for the driver motor within a further range of adjustment ( ) of the seat back ( ).

The method of electronically monitoring and controlling a process for moving and/or positioning at least one window and/or sunroof of a motor vehicle to provide protection from pinching includes supplying an input variable, for example drive voltage, and an output variable, for example window position, to a detection device; storing a model in the form of a differential equation describing the process for moving and/or positioning the window and/or sunroof in terms of process parameters in the detection device; optimizing the process parameters of the model according to the input and output variables and storing values of the optimized process parameters in the detection device for the purpose of monitoring; continually evaluating current values of the process parameters obtained by the optimizing by comparing the current values with the stored values; calculating a process correcting quantity in the detection device for adjusting the window and/or sunroof according to the comparing and influencing the process by feeding the correcting quantity into the process, so that the process can be halted when pinching is detected.

In a pump, particularly for cooling water, with an impeller wheel ( ) that is supported so that it can rotate in a pump chamber ( ), an excitation device ( ) for driving the impeller wheel ( ) to rotate, and a control circuit ( ) for the excitation device ( ), the control circuit ( ) and the excitation device ( ) are thermally separated from one another by the pump chamber ( ). The waste heat of the excitation device ( ) is removed by the fluid circulating in the pump chamber ( ) to the extent that the control circuit ( ) is prevented from overheating.

A sensor is proposed that has a measuring diaphragm (,), with at least one resistor measurement bridge (,); a deflection of the measuring diaphragm (,) causes mistuning of the respective measurement bridge (,), and the resultant change in the bridge diagonal voltage can be evaluated. The sensor (,) has one resistor measurement bridge (,) on each half (,) of the measuring diaphragm (,), and in each of the resistor measurement bridges (,), two opposed bridge branches (R,R,) are changed in their resistance values (&Dgr;R) by radial compressive offset, and the respectively other bridge branches (R,R,) are altered in their resistances by radial or tangential elongation.

A rotational sensor has a vibrating weight with two acceleration sensors mounted on it. The two acceleration sensors are designed to detect forces acting at a right angle to each other. The vibrating weight is set in vibration by means of driving devices, and rotation of the rotational sensor about two axes of rotation that are normal to each other is detected with the help of the acceleration sensors. The Coriolis forces in a plane are determined in this way.

Rotational rate sensor with two acceleration sensors

A rotor for detecting inclination angles in relation to a defined rotational axis perpendicular to the direction of the field of gravity is proposed. In the center area of the sensor interior, enclosed by a housing, a mounting (25) is located, which is fixed in relation to the housing (30), and on which a seismic mass is suspended so that it can swing. The seismic mass is formed in the shape of a rotor (10) which is asymmetrical in respect to the mounting (25) and which can perform excursions around an axis defined by the mounting (25). Portions (11, 12) of the rotor (10) constitute electrodes of a capacitor arrangement. A border (20), fixed in relation to the housing (30), is disposed around the rotor (10) parallel to the axis defined by the mounting (25). The portions (21, 22, 23) of the border (20) constitute the backplate electrodes of the capacitor arrangement.
