Abstract: A cushion of an airbag device includes an inner inflating section convexly inflating toward the rear of a vehicle and restraining the head of an occupant from the front of the vehicle, protrusions provided to the sides of the inner inflating section in a vehicle width direction and capable of inflating so as to protrude further toward the rear of the vehicle than the inner inflating section, and outer inflating sections provided between the inner inflating section and the protrusions and temporarily convexly inflating toward the rear of the vehicle within a smaller range than the expansion range of the inner inflating section and the protrusions. The outer inflating sections are squashed by the inner inflating section and the protrusions and, as a result, the protrusions are in a posture of being pulled toward a side of the inner inflating section.

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.

Abstract: An airbag device that can efficiently suppress an injury value for an occupant in an emergency includes a frontal airbag cushion that is expanded at a vehicle front side of a driver's seat and a curtain airbag cushion that is expanded at an outer side of the frontal airbag cushion in a vehicle width direction. The frontal airbag cushion includes an inner bag that is expanded by receiving a gas, inner vents that are disposed in the inner bag to discharge the gas, an outer bag that contains the inner bag therein and is expanded by receiving the gas from the inner vents and outer vents that are disposed in the outer bag to discharge the gas. A distance between the inner bag and the curtain airbag cushion is smaller than a width of a head of an occupant.

Abstract: [Problem] To provide an airbag apparatus in which the injury value of a passenger can be efficiently suppressed in an emergency. [Resolution means] An airbag apparatus 100 is provided with a cushion 108 which expands and deploys from in front of a seat 104. The cushion 108 is provided with: a front restraining part 128 which restrains the head 146 of a passenger 144 from the front of a vehicle; and protrusion parts 124, 126 which are provided beside the front restraining part 128 in the width direction of the vehicle and protrude and expand further towards the rear of the vehicle than the front restraining part 128.

Abstract: [Issue] An objective of providing an airbag device enabling efficiently suppressing injury of the occupant during an emergency. [Resolution Means] A representative structure of the airbag device 100 according to the present invention includes an inflator 112 that is installed on a vehicle and is able to supply gas, an airbag cushion 104 that expands and deploys in front of the seating position of the vehicle occupant based on the gas, and at least one internal tether 116 with a first end 122 connected to the seating position side inside the airbag cushion 104 and a second end 124 connected to the vehicle front side inside the airbag cushion 104. The airbag cushion 104 is characterized by a recessed concave part 114 formed through pulling of the internal tether 116 on the center of the seating position side.

Abstract: [Problem] To provide an airbag anticipated to suitably protect a passenger of a vehicle. [Resolution means] The airbag according to the present embodiment includes: an inner bag having a facing surface facing a passenger of a vehicle in the deployed state; an outer bag which is provided so as to surround the outer periphery of the inner bag with the facing surface exposed; and two protrusion parts which are provided in the outer bag and respectively disposed on the left and right sides in the width direction of the vehicle with respect to the facing surface so as to protrude rearward. For example, the inner bag and the outer bag may be partitioned by a common partition wall, with a ventilation port formed in the partition wall. Moreover, for example, the inner bag and the outer bag may each be independent bag bodies, a ventilation port may be formed in both the inner bag and the outer bag, and the inner bag and the outer bag may be coupled around the ventilation port.
