PROBLEM TO BE SOLVED: To quickly incline an upper body of a passenger at the time of side collision, with a low-cost configuration, even with a vehicle of narrow car width.SOLUTION: When a side surface collision is detected by a side collision detection means 12, a holding means 15 holds a pretensioner 13 in a non-operation state, so that a seat belt is relaxed so as to relax constraining of an upper body of a passenger. Thus, at the time of side surface collision, the pretensioner 13 is held in non-operation state by the holding means 15, and the seat belt is relaxed to weaken constraining force of a passenger with the seat belt, thus, in a low-cost configuration, a state is easily formed in which an upper body of a passenger M can be inclined.SELECTED DRAWING: Figure 3
【課題】車幅の狭い車両であっても、安価な構成により側突時に乗員の上体を素早く傾けられるようにする。【解決手段】側突検出手段12により側面衝突が検出されたときに、保持手段15により、プリテンショナ13を非作動状態に保持して乗員の上半身の拘束を緩和すべくシートベルトを緩める。これにより、側面衝突時に保持手段15によりプリテンショナ13が非作動状態に保持され、シートベルトが緩められてシートベルトによる乗員の拘束力が弱まることになり、安価な構成によって乗員Mの上体を傾けることが可能な状態を容易に形成できる。【選択図】図3
