Patent Images
1. A vehicle rollover sensor comprising:
- a rotor having a rotor axis and mountable within a vehicle, said rotor being inertially balanced and freely rotatable about the rotor axis, said rotor axis being fixed relative to the vehicle; and
a detector for detecting rotation of said rotor about the rotor axis, said detector being operative to provide a detector signal indicative of a rate of relative rotation, whereby a vehicle rollover condition may be determined based on the detector signal.

Abstract
A vehicle rollover sensor (10) includes a rotor (12) having a central rotor axis (14) and which is mountable within a vehicle (18). The rotor (12) is inertially balanced and freely rotatable about the rotor axis (14). The sensor (10) also includes a detector (32) for detecting rotation of the rotor (12) relative to the rotor axis (14). The detector (32) is operative to provide a detector signal (43) indicative of the detected relative rotation. The detector signal (43) is used to determine the occurrence of a vehicle rollover condition.
