  • Publication number: 20200391686
    Abstract: Provided is a vehicle seat having a seat cushion, a submarine bar, an airbag main body, a bag retainer, and a transmission member. The seat cushion is shifted by a tilting mechanism or a lifting mechanism. The submarine bar is suspended across side frames. The airbag main body inflates and deploys inside the seat cushion. The bag retainer is at least partially disposed inside the airbag main body and retains an inflator. The transmission member transmits, to the submarine bar, a load that acts on the bag retainer when the airbag main body inflates and deploys in a state where the seat cushion has been shifted upward.
