An airbag has a main bag portion that is provided with an occupant protective surface which is disposed to face the occupant and an auxiliary bag portion that can be disposed on the left side of the storage part, between the main bag portion and a vehicle body-side member, when the inflation is completed. The auxiliary bag portion is configured to enable an inflating gas to flow into an inside thereof through the main bag portion, is configured to be inflated under control of a control mechanism in association with a collision mode of a vehicle, and is configured to be interposed between the main bag portion and the vehicle body-side member and to be capable of pushing a region of the occupant protective surface on a side of the auxiliary bag portion, which is inflated, toward a side of the occupant, when the inflation is completed.

Airbag apparatus

An airbag includes an internal pressure adjusting mechanism, including: a tether arranged in a bag part; a long side part; and a short side part; and adjusting an exhaust of the inflation gas: to be in an exhaust mode in which the exhaust is facilitated when the tether is loosened; and to be in an exhaust suppression mode in which the exhaust is suppressed when the tether is stretched. In a state where the tether is loosened during the exhaust mode, facing edge parts of the long side part and the short side part are separable. In a state where the tether is stretched during the exhaust suppression mode, the facing edge part of the long side part and a root side part are inflated around the short side part and a leading edge side part contacts a back surface side of the short side part.

Airbag

An airbag includes a driver side portion having an outer peripheral wall to receive a driver at the time of completion of inflation; and a steering wheel side portion. The steering wheel side portion is provided with an inflow opening to allow inflation gas to flow in, and an attaching seat which is disposed on a peripheral edge of the inflow opening and attached to the central portion of the steering wheel; a support inflation portion protruding from a front side of the attaching seat toward a front side of the steering wheel is arranged on the steering wheel side portion; and a support surface portion. The support surface portion is abutted to and supported by a front surface side of the steering wheel and is arranged on a region on a rear surface side of the support inflation portion from a base portion to a tip end portion.

An airbag includes: an outer member configured to form an outer peripheral wall upon completing inflation, which includes a driver side portion configured to receive a driver, and a steering-wheel side portion supported by a steering wheel; and an inner member provided to expand inside the outer member. The inner member has a supply port for supplying inflation gas to the outer member and covers the inflow opening of the outer member to be arranged on an upstream side of flow of the inflation gas flowing from the inflow opening into the airbag such that a higher pressure can be maintained in the inner member than the outer member. The inner member includes a front support inflating portion configured to support a portion of the driver side portion of the outer member at least at a front side upon completing inflation of the airbag.

An airbag includes: a bag body forming the outer peripheral wall; and a regulating member disposed on an outer peripheral side of the bag body at a time of inflation completion of the bag body. The regulating member is configured so as to be able to regulate the bag body so that an area ranging from the vicinity of a joint portion for mutually joining the outer peripheral edge of the vehicle body side panel and the outer peripheral edge of the occupant side panel to a side of the gas inflow port at the time of inflation completion of the airbag is made smaller in external dimensions and reduced in size than an area at a time of free inflation state of the bag body.

An occupant protection device includes an airbag, covering a front area from a passenger seat to a driver seat at the time of completion of inflation, including: a passenger-seat receiving inflation part; a driver-seat receiving inflation part; an inflow side inflation part; an end-side flow path part disposed so that both ends of the inflow side inflation part in the right and left direction are respectively connected with end edges of the passenger-seat receiving inflation part and the driver-seat receiving inflation part; and a central flow path part disposed so that the inflow side inflation part is connected with a proximity edge part where the passenger-seat receiving inflation part is close to the driver-seat receiving inflation part, wherein the inflow side inflation part is configured so that at least both right and left end sides at the time of completion of inflation are attached in the housing portion.

Occupant protection device

An airbag device includes an airbag stored in a storage part provided in front of an occupant seated on a seat. The airbag has an occupant protecting section configured to protect the occupant on a rear surface at the time of completion of inflation; the occupant protecting section includes: an upper half body restraining surface configured to receive an upper half body of the occupant; and a head receiving section formed in a left region and a right region of a center in a left-right direction of the occupant protecting section to protrude rearward from the upper half body restraining surface, in a region above the upper half body restraining surface. The head receiving section is configured so that a part between a left restraining surface and a right restraining surface upon completion of inflation is continued from the upper half body restraining surface.
