Abstract: A body protection device in the form of an inflatable vest includes an inflation mechanism that is actuated upon separation or removal of the wearer from a vehicle. A compressed gas cartridge is held in an interior pocket of the vest and attached to an inflatable bladder. The compressed gas cartridge communicates with the interior of the bladder through a cartridge actuation mechanism and an inflation tube. The cartridge actuation mechanism includes a triggering device that operates an actuation lever to open the cartridge. The actuation lever is actuated in response to a pulling force of predetermined magnitude that detaches the triggering mechanism from the actuation mechanism. The actuation lever is connected to the vehicle by a lanyard, which lanyard, when a wearer of the vest is forcibly separated from the vehicle, actuates the triggering device before detaching from the actuation mechanism, thereby opening the cartridge to inflate the vest.
