Abstract

A device for the detection of side impact and a pressure sensor, a mechanical switch being assigned to the pressure sensor as a plausibility sensor. This mechanical sensor is preferably situated in the housing of the pressure sensor.

Claims

1-8. -8. (canceled)

9. A device for a detection of a side impact to a vehicle, comprising:

a pressure sensor situated in a side part of the vehicle, the pressure sensor having a housing; and

a plausibility sensor, the plausibility sensor being a switch that is assigned to the housing of the pressure sensor.

10. The device according to claim 9, wherein the switch is situated in the housing.

11. The device according to claim 9, wherein the switch is a Hamlin switch.

12. The device according to claim 9, wherein the switch is connected directly to an ignition output stage in such a way that the switch releases the ignition output stage as a function of its state.

13. The device according to claim 9, further comprising a processor for releasing an ignition output stage as a function of a signal of the switch.

14. The device according to claim 13, wherein the switch is situated in such a way that the switch interrupts a data transmission from the pressure sensor to the processor, as a function of its state.

15. The device according to claim 9, wherein the signal of the switch is coded directly with a pressure signal.

16. A pressure sensor for a detection of a side impact to a vehicle, comprising:

a housing; and

a switch situated in the housing.
