In a triggering system for activating a safety device, an acceleration sensor outputs a signal for a time duration in which an acceleration impulse exceeds an acceleration magnitude threshold. A first switching device receives the signal output by the acceleration sensor, and electrically connects a power supply to at least one safety response device for the time duration. A time delay device, upon completion of a delay time after receiving the signal output by the acceleration sensor, outputs a signal for the time duration. A second switching device receives the signal output by the time delay device, and electrically connects the power supply to the at least one safety response device for the time duration. When the time duration exceeds the delay time, the first switching device and the second switching device concurrently electrically connect the safety response device to the power supply, activating the safety response device.
