A pressure sensor assembly having a pressure tube, in which a diaphragm is situated as a pressure pickup, and having means for detecting the diaphragm deformations, which allow a spatial separation between the measuring medium acting on the diaphragm and the means for detecting the diaphragm deformations. The diaphragm of this pressure sensor assembly includes at least two diaphragm sections oriented at an angle to one another. A first diaphragm section is situated as a partition diaphragm in the cross-section of the pressure tube, while at least one second diaphragm section forms an area of the wall of the pressure tube as a side wall diaphragm. The means for detecting diaphragm deformations are situated on the outer side of the pressure tube on the side wall diaphragm.

A device is proposed for detecting a collision of a vehicle with an obstacle, in which an ultrasonic receiver unit is used to detect the sound produced by the collision, and a collision of the vehicle is thus detected through the evaluation of the ultrasonic signals.

A force sensor, in particular for detecting the forces on a vehicle seat, includes a force measurement cell () that has a Hall element. The force measurement cell () includes at least one bending bar (), which from the exertion of force to be detected exeris an influence on the magnetic field in the region of a magnetic-field-sensitive sensor element () of the measurement cell (). The sensing is done with a Hall element (), held on the at least one bending bar (), which element, under the force exerted on the bending bar (), can be deflected in the field of a relatively stationary permanent magnet (), and a magnetic diagnosis field in the region of the Hall element () can be generated whose field lines are located in the plane of the sensor element without influencing the measurement field.

A dynamometer () has a pickup element (), in which a permanent magnet () and a sensor () are disposed. At least the permanent magnet () is surrounded by ferromagnetic material, and the spacing of the permanent magnet () from the ferromagnetic material changes upon imposition of a force (F) upon the pickup element (). This change in the spacing causes a change in the field intensity of the permanent magnet (), which is detected by means of the sensor () and converted into a corresponding signal.
