To provide an airbag which is installed to a seat back or head rest, has a front expansion part expanding at the front of an occupant and the lateral expansion parts expanding at both sides of the head of an occupant and is capable of controlling the internal pressure of a lower part in the front expansion part and that of an upper part therein, and to provide an occupant restraint device equipped with the above airbag.SOLUTION: An airbag 1 comprises a pair of lateral expansion parts 2, 2 expanding and spreading toward a front passing through both sides of the head H of an occupant P from the upper part of a seat back S, and a front expansion part 3 continuing to the front of the lateral expansion parts 2, 2 and expanding and spreading to the front of the upper half of an occupant P's body. The airbag 1 expands and spreads firstly upward from the upper part of the seat back S and then, the lateral expansion part 2 expands and spreads forward above the occupant head H. After that, the front expansion part 3 expands and spreads downward at the front of the occupant head H, and an upper expansion part 7 expands and spreads from the lateral expansion part 2.SELECTED DRAWING: Figure 1

    【課題】シートバック又はヘッドレストに設置され、乗員の前方で膨張する前膨張部と、乗員の頭部の両側方で膨張する横膨張部とを有するエアバッグであって、前膨張部の下部の内圧と前膨張部の上部の内圧とをコントロールすることが可能なエアバッグと、このエアバッグを備えた乗員拘束装置を提供する。【解決手段】エアバッグ1は、シートバックSの上部から乗員Pの頭部Hの左右両側を通って前方に向って膨張展開する1対の横膨張部2,2と、該横膨張部2,2の前部に連なり、乗員Pの上半身の前方に膨張展開する前膨張部3とを有する。インフレータが作動すると、エアバッグ1はシートバックSの上部からまず上方に膨張展開する。次いで横膨張部2が乗員頭部Hよりも上方で前方に膨張展開し、その後、前膨張部3が乗員頭部Hの前方で下方に膨張展開する。上方膨張部7が横膨張部2から膨張展開する。【選択図】図1
