Abstract: A vehicle seat includes: a seat cushion in which a front panel extends between front parts of right and left side frames and a front rod extends between the front parts of the right and left side frames at a position rearward of the front panel in a longitudinal direction of a vehicle; a cushion airbag device mounted in a front part of the seat cushion and configured to inflate and deploy a cushion airbag when a frontal collision of the vehicle occurs; and a bag support fixed to the front rod, the cushion airbag being fixed to the bag support at a position rearward of the front rod in the longitudinal direction of the vehicle.

Abstract: An occupant protection device, for a vehicle which protects an occupant seated on a seating surface of a seat, includes: a first push-up mechanism which pushes up a waist portion of the occupant by raising a rear portion of the seating surface; a second push-up mechanism which pushes up a thigh portion of the occupant by raising a front portion of the seating surface; and a control unit which controls operations of the first push-up mechanism and the second push-up mechanism. The control unit operates the first push-up mechanism and then operates the second push-up mechanism when an impact applied to the vehicle from the front of the seat is detected or predicted.

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.

Abstract: A seat cushion airbag apparatus includes a support portion, an airbag, and a fastening portion. The support portion is arranged below the cushion portion of a conveyance seat. The airbag is arranged between the cushion portion and the support portion and at the center portion in the width direction of the conveyance seat. The fastening portion fastens the airbag to the support portion and is disposed in the lower portion of the airbag in the inflated state at a position rearward of the center in the front-rear direction.

Abstract: A vehicle seat includes a seat cushion including a cover, a frame and a pad, a plurality of parts of the cover being restrained to the frame and the pad; a cushion airbag device mounted in a front portion in the seat cushion and configured to inflate and deploy an airbag at a time of a frontal collision of a vehicle; and a restraint release part provided in a part of the cover positioned at at least one side in a seat front-rear direction with respect to the cushion airbag device among the plurality of parts of the cover. The restraint release part is configured to release the restraint of the part of the cover with an inflation pressure of the airbag.

Abstract: A seat device for a vehicle includes a seat for supporting a lower body of a vehicle occupant, and a backrest for supporting an upper body of the occupant. The seat device further includes an arresting portion that is stored in a storage position disposed in the seat. The arresting portion is configured to be deployed from the storage position and restrain a part of the lower body of the occupant from moving forward in the event of a collision of the vehicle.
