DEVICE FOR ACTIVATING A SECURITY SYSTEM IN A VEHICLE
First Claim
1. A device for activating a security system in a vehicle with at least two vehicle sensors (4), each of which can record vibrations in frequency ranges, which are generated both by an acceleration and by structure-borne noise, and which comprise in each case at least one measuring value sensor (4.1) for recording vibrations, and a central unit (2) which evaluates the signals from the vehicle sensors (4), and which activates the security system according to said signals,characterised in thatin each case, the vehicle sensorsa) comprise a first sensitivity direction (7.1) of at least one measuring value sensor (4.1) for recording the acceleration, andb) a second direction of sensitivity (7.2) of at least one measuring value sensor (4.1) for recording the structure-borne noisec) the first direction of sensitivity (7.1) and the second direction of sensitivity (7.2) of each vehicle sensor (4) are aligned to each other at an angle of almost 90 degreesd) whereby the vehicle sensors are arranged in relation to each other in such a manner that the first sensitivity direction (7.1) of the first vehicle sensor and the second sensitivity direction (7.2) of the second vehicle sensor, and the second sensitivity direction (7.1) of the first vehicle sensor and the first direction of sensitivity (7.2) of the second vehicle sensor are almost identical.

Abstract
Disclosed is a device for activating a security system in a vehicle including a first and second vehicle sensor (4). The sensor include, respectively, a measuring value sensor (4.1) which can detect acceleration and structure-borne noise, and a central unit (2) which evaluates the signals of at least two vehicle sensors (4) and activates the security system according to the signals. The first and second vehicle sensors have a first direction of sensitivity for at least one measuring value sensor (4.1), which is used to detect acceleration, and a second direction of sensitivity for at least one measuring value sensor (4.1) which is used to detect structure-borne noise.
