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: A knee airbag device according to the present invention includes: an airbag that restrains a lower extremity of an occupant by expanding and deploying below an instrument panel of a vehicle; and an inflator that supplies expansion gas to the airbag. The airbag includes, when the inside of the vehicle is a first side and the outside of the vehicle is a second side, a first portion positioned on the first side and a second portion positioned on the second side. Furthermore, the first portion of the airbag protrudes more toward the occupant side than the second portion.

Abstract: An airbag that includes an inner bag having a facing surface configured to face a passenger of a vehicle in the deployed state, an outer bag that surrounds the outer periphery of the inner bag with the facing surface exposed, and two protrusion parts which are provided in the outer bag and are 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. 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, 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.

Abstract: An airbag apparatus with a cushion that expands and deploys from in front of a seat is provided. The cushion includes a front restraining part that restrains a head of a passenger from the front of a vehicle. The cushion further includes protrusion parts that are provided beside the front restraining part in the width direction of the vehicle and protrude and expand further towards the rear of the vehicle than the front restraining part. Inner tethers inside the cushion are connected to the front restraining part and to which tension is applied to pull the front restraining part towards the front of the vehicle. Outer tethers are connected to the protrusion parts and to which tension is applied to pull the protrusion parts towards the front of the vehicle. When tension is applied to the inner tethers, force towards the inner tethers is applied to the outer tethers.
