Abstract
An apparatus for actuating an actuatable vehicle safety device, such as an airbag inflator, includes an ignitable pyrotechnic transmission line having one end connected with the vehicle safety device. The safety device actuates in response to ignition of the pyrotechnic transmission line. The other end of the pyrotechnic transmission line is connected with an actuatable semiconductor bridge which, when actuated, ignites the pyrotechnic transmission line. The semiconductor bridge actuates in response to receiving a firing signal indicative of a vehicle collision from an impact sensor. Thus, when a vehicle collision occurs, the impact sensor provides the firing signal to actuate the semiconductor bridge which, in turn, ignites the pyrotechnic transmission line to thereby actuate the airbag inflator.
