PROBLEM TO BE SOLVED: To improve occupant protection performance in the event of front collision of a vehicle.SOLUTION: An occupant restricting device 10 for a vehicle comprises: a seat belt 12; a collision prediction sensor 14; a brake device 16 (space increasing means) that increases a space S between an occupant 26 and the seat back 32 of a vehicle seat 24; an explosive type pretensioner 18 and an electric motor 20 (actuator), for pulling in the seat belt 12; and a control section 22 that, in a case where a front collision of the vehicle is detected in advance by the collision prediction sensor 14, increases the space S between the occupant 26 and the seat back 32 by the brake device 16 (space increasing means ), also starts pulling in the seat belt 12 by the explosive type pretensioner 18 and the electric motor 20 (actuator), and, until forward movement of the occupant 26 starts at least after the front collision, continuously inputs load to the passenger 26 from the seat belt 12 and continuously move the occupant 26 in a vehicle backward direction.SELECTED DRAWING: Figure 1

    【課題】車両の前面衝突時における乗員保護性能を向上させる。【解決手段】車両用乗員拘束装置10は、シートベルト12と、衝突予知センサ14と、乗員26と車両用シート24のシートバック32との間の間隙Sを拡大させるブレーキ装置16(間隙拡大手段)と、シートベルト12を引き込む火薬式プリテンショナ18及び電動モータ20(アクチュエータ)と、衝突予知センサ14により車両の前面衝突が事前に検知された場合、ブレーキ装置16(間隙拡大手段)により乗員26とシートバック32との間隙Sを拡大させると共に火薬式プリテンショナ18及び電動モータ20(アクチュエータ)によってシートベルト12の引込みを開始し、少なくとも前面衝突発生後に乗員26の前方移動が始まるまで、シートベルト12から乗員26に荷重を入力し続け乗員26を車両後方へ移動させ続ける制御部22と、を有する。【選択図】図1
