In a vehicle seat having an airbag module placed in the seatback thereof, the load that may be applied to the back side of the seatback is prevented from being applied to the airbag module. The vehicle seat (1, 300, 400) comprise a seatback frame (19) including a pair of side members (26, 301) extending vertically along either side thereof and providing a structural framework of a seatback, a plate member (20, 402) positioned behind the seatback frame and including an extension (32, 410) extending in an outboard direction from the side member located on an outboard side of the seatback frame, a mounting member connected to the outboard side member, and an airbag module (23) positioned on a front side of the extension and connected to the outboard side member via the mounting member, a clearance (S) being defined between the airbag module and the extension.

A vehicle seat storage system includes a passenger seat including a seatback and a seat base. The seat has a seating condition where the seat is releasably attached to a floor of the vehicle and a stowed condition where the seat is unattached from the floor and the seat base is folded against the seatback. The seat includes risers pivotally attached to the seat base. The risers have a deployed position for supporting the seat base in the seating condition and a folded position where the risers are folded inwardly against the seat base in the stowed condition. An interior sidewall of the vehicle includes a recessed portion sized and configured to receive the seat in the stowed condition. The interior sidewall includes a guide configured to direct the seat in the stowed condition into and out of the recessed portion and support the seat in recessed portion.

A seat assembly for a vehicle includes a foldable seat actuatable at least to a stowed configuration and to a deployed configuration, The seat assembly also includes a seat actuation assist mechanism being structured to generate a seat actuation assist force facilitating a movement of the seat from any one of the stowed configuration and the deployed configuration to the other one of the stowed configuration and the deployed configuration. The assist force is generated responsive to movement of the seat from the other one of the stowed configuration and the deployed configuration to the one of the stowed configuration and the deployed configuration.

The seat includes risers pivotally attached to the seat base. The risers have a deployed position for supporting the seat base in the seating condition and a folded position where the risers are folded inwardly against the seat base in the stowed condition. An interior sidewall of the vehicle includes a recessed portion sized and configured to receive the seat in the stowed condition. The interior sidewall includes a guide configured to direct the seat in the stowed condition into and out of the recessed portion and support the seat in recessed portion.

A vehicle seat includes: a leg member, attached to a lower end portion of a seat main body movable between use and stowed positions and movable along with a seat main body, and a leg holding member, elastically deformable to hold a holding target portion of the leg member. The leg holding member includes separated first and second portions which are configured to hold the holding target portion having passed through an introduction opening of the leg holding member formed between the first and second portions with the holding target portion interposed between the first and second portions when the leg member moves along with the seat main body moving toward the use position. A deformation amount restriction portion restricts deformation generated when the leg holding member is elastically deformed so that the first and second portions are separated when the holding target portion passes through the introduction opening.

A vehicular boarding assistance device includes: a slope main body provided in a body of a vehicle so as to project and retract and configured to form a slope by being bridged between the body and a ground surface in a state of projecting from the body; a slope drive source configured to drive the slope main body so as to project and retract; a seat drive source configured to drive at least one of a plurality of seats installed on a floor of the vehicle; and a control unit configured to drive and control the slope drive source such that the slope main body projects and drive and control the seat drive source such that an occupying region of a boarding assistance target moving on the slope and moving to the floor is secured on the floor.

A seat is provided in which a seat cushion is pivotally coupled to a seat back by a recliner assembly. The recliner assembly is selectively operable between a locked condition preventing pivotal movement of the seat back and an unlocked condition allowing pivotal movement of the seat back. A riser assembly supports the seat assembly above a floor, such as the floor of a vehicle, and is configured for actuation and movement of the seat assembly between a generally upright seating position, a pitched easy entry position tilted forwardly and downwardly towards the floor to allow easier ingress and egress behind the seat, and a stowed position recessed within a compartment below the floor.

A vehicle seat is provided with a plate member attached to the back of the seat back. The plate member is configured by a core plate and a cover that covers the core plate, the plate member is sewed together with a cover of the back of the seat back, and a sewed part of the cover of the plate member and the cover of the seat back functions as a turning axis of the plate member. The plate member is turned an unfolded state covering concave clearance formed between the back directed upward of the seat back and a floor surface on the back side by pushing down the seat back forward, and the plate member is turned a housed state in which the plate member is piled on the back of the seat back by raising the seat back backward.
