Abstract: An apparatus (10) senses the crushing rate of a vehicle body portion, such as a vehicle door (12), during a collision. The apparatus comprises a first optical transmitter (22) which provides a first light beam. A first optical receiver (24) is spaced apart from the first optical transmitter along the vehicle body portion, and receives the first light beam from the first optical transmitter. A second optical transmitter (32) is spaced apart from the first optical transmitter and the first optical receiver, and provides a second light beam. A second optical receiver (34) is spaced apart from the second optical transmitter along the vehicle body portion, and receives the second light beam from the second optical transmitter. A controler (50) is responsive to interruption of the first and second light beams at different times to provide a signal (57) indicative of the crushing rate of the vehicle body portion.
