PROBLEM TO BE SOLVED: To reduce a trouble caused by incomplete restriction of a seating person who has soft part of abdomen wound around by a waist seat belt in a vehicular seating person restraint device that includes a set belt device comprising an air bag device and the waist seat belt.SOLUTION: A vehicular seating person restraint device 10 comprises: a seat belt device 20 which includes a waist seat belt 27 worn on a lumbar part of a seating person P seated on a vehicular seat 12; and an air bag device 40 which include an air bag restraining the seating person P. The seat belt device 20 comprises: a sensor 33 which is arranged at the waist seat belt 27 to detect load applied to the waist seat belt 27 from the seating person P; load distribution calculation means 82 which calculates load distribution of the waist seat belt 27; and waist seat belt position determination means 84 which determines deviation of the waist seat belt 27 on the basis of the obtained load distribution. The seat belt device 20 controls inflation and expansion of the air bag corresponding to crash on the basis of the determination result of the waist seat belt position determination means 84.

    【課題】エアバッグ装置と腰部シートベルトを有するシートベルト装置とを備える車両用着座者拘束装置において、腰部シートベルトが柔らかな腹部に掛け回されて着座者が不完全に拘束されたことに起因する不具合を低減すること。【解決手段】車両用シート12の着座者Pの腰部に装着される腰部シートベルト27を有するシートベルト装置20と、着座者Pを拘束するエアバッグを有するエアバッグ装置40と、を備える車両用着座者拘束装置10である。シートベルト装置20は、腰部シートベルト27に設けられて着座者Pから付加される荷重を検知するセンサ33と、腰部シートベルト27の荷重分布を算出する荷重分布算出手段82と、得られた荷重分布に基づいて腰部シートベルト27のずれを判定する腰部シートベルト位置判定手段84と、を有し、腰部シートベルト位置判定手段84の判定結果に基づいて衝突に対応させたエアバッグの膨張展開を制御する。【選択図】図1
