Abstract
A safety system includes a seatbelt apparatus for supporting a shoulder of a vehicle occupant, an airbag apparatus having an airbag body, and control means for controlling a sealing member. The airbag body is inflated to receive the occupant by gas introduced into the airbag body. The airbag body has first and second ports for exhausting the gas. The sealing member is disposed on the second exhaust port. The sealing member is set to either one of a first state where the gas is prevented from being exhausted from the second exhaust port and a second state where the gas is allowed to be exhausted. The sealing member is ordinarily set to the first state. The seatbelt apparatus outputs a seatbelt apparatus application signal to the control means when the seatbelt apparatus is applied to the occupant. The control means set the sealing means to the second state when the control means receives the seatbelt apparatus application signal.
