Abstract: A cushion 108 of an airbag device 100 includes: an inner inflating section 158 which convexly inflates toward the rear of a vehicle and which restrains the head 146 of an occupant 144 from the front of the vehicle; protrusions 124 and 126 which are provided to the sides of the inner inflating section 158 in a vehicle width direction and which are capable of inflating so as to protrude further toward the rear of the vehicle than the inner inflating section 158; and outer inflating sections 160 and 162 which are provided between the inner inflating section 158 and the protrusions 124 and 126 and which temporarily convexly inflate toward the rear of the vehicle within a smaller range than the expansion range of the inner inflating section 158 and the protrusions 124 and 126. The outer inflating sections 160 and 162 are squashed by the inner inflating section 158 and the protrusions 124 and 126 and, as a result, the protrusions 124 and 126 are in a posture of being pulled toward a side of the inner inflating section 158.

Abstract: An airbag device 100 includes: an inflator 112 that is provided in a vehicle and capable of supplying gas; and an outer bag 114 that inflates, by using the gas, in a prescribed shape in front of an occupant 134 sitting in a seat 102 of the vehicle. The outer bag 114 includes an outside base fabric 122 forming an outer surface thereof, an opening part 126 provided in a prescribed area of the outside base fabric 122, and an inside base fabric 124 forming an inner peripheral surface thereof recessed in a concave shape from the opening part 126 and inflating so as to protrude partially from the opening part 126 to a side of the seat. In the airbag device 100, the inside base fabric 124 has lower tension than the outside base fabric 122 and restrains the occupant 134.
