Abstract
A system ( ) for controlling an actuatable occupant protection device ( ) includes an actuatable headrest device ( ) which, when actuated, helps protect an occupant of a vehicle seat ( ). A crash sensor ( ) is operative to sense a condition of a vehicle ( ) and provide a crash sensor signal having an electrical characteristic indicative of the sensed vehicle condition. A controller ( ) is coupled to the actuatable headrest device ( ) and the crash sensor ( ). The controller ( ) determines a crash velocity value and a crash displacement value based on the crash sensor signal. The controller ( ) has a threshold value functionally related to the determined crash displacement value. The controller ( ) controls actuation of the actuatable headrest device ( ) in response to the determined crash velocity value relative to the threshold value.
