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.

In a vehicle seat, a back pad outer skin covering a surface of a back pad includes a first portion covering a surface of one part, including a side face, of a bolster pad part, and second portions covering a surface of another part that is different from the one part of the bolster pad part. A bound part is formed by binding to each other mutually adjacent end parts of the first portion and the second portions and extremity parts of expansive force transmission webbings having base portions fixed to a frame, the bound part being capable of breaking when an airbag is made to expand. A non-stretchable cloth member is disposed on a reverse side of specific outer skin portions, covering a front face of the bolster pad part, of the second portions.

A vehicular seat cushion airbag is disclosed. The seat cushion airbag includes a first cushion, which is mounted on a seat cushion of a vehicle so as to be expanded at the rear portion of a passenger's thigh, and a second cushion, which extends from the first cushion in an upward direction of a bolster portion of the seat cushion so as to be expanded toward the lateral side surface of the passenger's thigh, wherein the first cushion is expanded at the rear portion of the passenger's thigh so as to prevent forward movement of the passenger's pelvis, and the second cushion is expanded toward the lateral side surface of the passenger's thigh so as to prevent outward spreading of the passenger's legs.

A vehicle center airbag may include a main cushion and a plurality of sub-cushions. The main cushion is mounted on a lateral surface of a seat back and is deployed in a forward direction, being positioned beside a passenger when a side collision occurs. The sub-cushions are configured to communicate with the main cushion and are deployed upwards from the top portion of the main cushion. When the sub-cushions are deployed, they extend in a forward-backward direction of the vehicle and are positioned above the torso of the passenger.
