  • Patent number: 11072305
    Abstract: There is provided a passenger seat air bag having a portion which is unfolded to a side toward a center side of a vehicle in which a pressure difference in the portion is suppressed. A passenger seat air bag includes a front unfolding portion which is unfolded in front of the passenger seat, and a side unfolding portion which is in communication with the front unfolding portion and which is unfolded to side, of the passenger seat, nearer to a center of the vehicle. A horizontal tether is provided in the side unfolding portion in an arrangement which is approximately horizontal during unfolding. When unfolding gas is injected from the front to the air bag, because the horizontal tether does not block flow of the unfolding gas, pressure us the side unfolding portion is made uniform.
