To improve occupant protection performance by correcting a posture of an occupant when a collision of a vehicle occurs.SOLUTION: When a collision of a vehicle is predicted (100 is Y), an occupant is inclined rearward by energizing a back section electrode provided in a seat back section of a seat on which the occupant is seated if the collision occurs ahead of the occupant and the occupant has a forward inclined posture (110 is Y). If the collision occurs ahead of the occupant and the occupant has a rearward inclined posture (114 is Y), the occupant is inclined forward by energizing an abdominal section electrode provided in a lap belt section of the seat belt that the occupant wears. When the collision occurs at a left side of the occupant (118 is Y), the occupant is inclined in a right direction by energizing each right side electrode of the back section electrode and a seat face electrode provided in a seat cushion section of the seat. When the collision occurs at a right side of the occupant (122 is Y), the occupant is inclined in a left direction by energizing each left side electrode out of the back section electrode and the seat face electrode.SELECTED DRAWING: Figure 4
【課題】車両が衝突する際に乗員の姿勢を矯正して乗員保護性能を向上させる。【解決手段】車両の衝突が予測された場合(100がY)に、衝突が乗員の前方で発生しかつ乗員の姿勢が前傾であれば(110がY)、乗員が着座しているシートのシートバック部に設けられた背部電極に通電することで乗員を後方へ傾斜させ、衝突が乗員の前方で発生しかつ乗員の姿勢が後傾であれば(114がY)、乗員が装着しているシートベルトのラップベルト部分に設けられた腹部電極に通電することで乗員を前方へ傾斜させる。衝突が乗員の左側方で発生する場合(118がY)は、背部電極及びシートのシートクッション部に設けられた座面電極のうちの右側の電極に各々に通電することで乗員を右方向へ傾斜させ、衝突が乗員の右側方で発生する場合(122がY)は、背部電極及び座面電極のうちの左側の電極に各々に通電することで乗員を左方向へ傾斜させる。【選択図】図4
