ABSTRACT:
An apparatus for restraining a vehicle occupant during a crash of the vehicle comprises a first crash sensor securable to the vehicle and having a sensitivity axis parallel with a front-to-rear axis of the vehicle. The first sensor provides a signal having a value functionally related to crash energy directed parallel to the front-to-rear axis of the vehicle and impervious to crash energy directed parallel to a side-to-side axis of the vehicle. A second crash sensor is also securable to the vehicle and has a sensitivity axis parallel with a side-to-side axis of the vehicle. The second crash sensor provides a signal having a value functionally related to crash energy directed parallel to the side-to-side axis of the vehicle and impervious to crash energy directed parallel to the front-to-rear axis of the vehicle. The first and second crash sensors have their sensitivity axes oriented along mutually orthogonal axes. The apparatus further comprises a controller connected to the first and second crash sensors for determining a crash vector of a crash condition in response to the signals from the first and second crash sensors. Each of a plurality of actuatable occupant restraint devices is connected to the controller. The controller controls which of the plurality of actuatable occupant restraint systems is or are actuated in response to the determined crash vector.
