  • Patent number: 10926731
    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.

  • Publication number: 20210039581
    Abstract: [Problem] To expand and deploy a hood-shaped airbag in a reliably sandwiched condition between the top of a shoulder of a seated occupant and a seatbelt in a normal set condition during a collision, and reduce injury to the occupant by a device other than an airbag such as a seatbelt or the like. [Resolution Means] An airbag device 11 contains an airbag 12 and inflator 13 integrally covering the head 2a and a side portion of a seated occupant 2. The airbag 12 in a flat condition prior to folding has a plurality of chambers 12c demarcated in a longitudinal direction. The chamber 12c has a head protecting chamber 12ca stored in an upper portion of a backrest portion 1b of a seat 1 and a pair of side protecting chambers 12cb stored in opposing positions separated in a vehicle width direction on both left and right sides of the backrest portion 1b.

  • Patent number: 10875484
    Abstract: An airbag device which is capable of efficiently suppressing an injury value of an occupant during an emergency. The airbag device 100 includes: an inflator 112 which is installed in a vehicle and which is capable of supplying gas; a main bag 114 which inflates to the front of a seat of the vehicle due to the gas; and an outer bag 116 which inflates so as to surround the main bag 114 due to the gas. The outer bag 116 includes an opening 118 which opens toward an occupant sitting on the seat and which exposes a portion (a rear region 120) of the main bag 114. The outer bag 116 surrounds and presses against the main bag 114, such that the portion of the main bag 114 protrudes from the opening 118 toward the occupant.
