  • Airbag cushion for vehicles
    Patent number: 8505970
    Abstract: An airbag cushion for vehicles includes a cushion body, vent holes, tubes and a tether. The vent holes are formed in the cushion body at opposite positions. The tubes are connected to the respective vent holes. The tubes are deployed out of the vent holes by deployment of the cushion body so that gas is discharged out of the cushion body through the tubes. The tether connects the tubes to each other and is severed when pressure in the cushion body reaches a predetermined degree. At the point of time at which the weight of the occupant is applied to the airbag cushion, the pressure in the airbag cushion is released, thus reducing the risk of the deployment of the airbag cushion injuring the occupant.
