Abstract
A safety device against a crash for a motorcycle is equipped with an air jacket, a cartridge and an opening device. Before the moving motorcycle collides with an obstacle existing ahead, a control signal is outputted and the opening device is operated when a first condition where interval between the motorcycle and the obstacle becomes a certain distance, and a second condition where relative velocity of the motorcycle toward the obstacle becomes over a certain value, are fulfilled. When this occurs, a seal plate of the cartridge is opened and pressurized gas filled in the cartridge flows into and expands an airbag of the air jacket whereby a rider of the moving motorcycle is protected.
