Patent attributes
A seat-mounted airbag device may include a seatback cushion built in a seatback of a vehicle. The seatback cushion includes side portions configured to be deployed from both side peripheral portions of a seat to a front of the seat to protect sides of an occupant when deployed by gas supplied by an inflator into the seatback cushion. Chest portions of the seatback cushion extend from front ends of the side portions to surround a chest of the occupant to protect the chest of the occupant. The airbag device includes one or more seatback tethers connected to a seat frame and mounted in the seat. When the seatback cushion is deployed, the seatback tethers are deployed along with the seatback cushion to support the chest in a top-bottom direction thereof, thereby supporting an upper body of the occupant.
