  • Patent number: 10752200
    Abstract: 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.

  • Patent number: 10507784
    Abstract: 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.

  • Patent number: 10507785
    Abstract: 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.

  • Patent number: 9738242
    Abstract: An airbag of an airbag device for a driver's seat includes an exhaust strap which includes a cover section that closes off an outer opening of a vent hole at airbag deployment and connecting bands extending from opposite sides of the cover section and joined to the center of a driver-side wall. When the driver-side wall of the airbag cushions the driver at airbag deployment and moves toward a vehicle-side wall, the connecting bands of the exhaust strap loosen and allow a distant edge region of the cover section to loosen and pass through the outer opening such that the outer opening and an inner opening communicate to open the vent hole. The cover section includes a reinforcing element that prevents the distant edge from slipping towards a proximate edge while allowing a bending deformation of the distant edge to pass through the outer opening and open the vent hole.

  • Patent number: 9650012
    Abstract: An airbag of an airbag device for a driver's seat includes an exhaust strap which includes a cover section that closes off an outer opening of a vent hole at airbag deployment in an openable fashion and connecting bands extending from opposite sides of the cover section and joined to a driver-side wall. The exhaust strap is so configured, when the driver-side wall of the airbag cushions the driver at airbag deployment and moves toward a vehicle-side wall, that the connecting bands loosen and allow a region towards a distant edge of the cover section to loosen and pass through the outer opening such that the outer opening and an inner opening communicate to open the vent hole. The length of the distant edge of the exhaust strap is shorter than a length of a proximate edge of the exhaust strap.

  • Patent number: 9499119
    Abstract: In a driver seat airbag apparatus, an airbag includes a belt member and a vent mechanism. The belt member includes two connecting sections extending from opposite sides of a cover portion for covering a vent hole. The vent mechanism includes an outer panel that has a vent hole and is located outside of the cover portion, an inner panel that has an inner opening and is located on an inner side of the cover portion, and a guide. The connecting sections run through the guide and move toward the vent hole for letting the cover portion open the vent hole. The guide holds the connecting sections such that the connecting sections serve as the tethers. A joint of the tethers to the driver side wall is located toward a center of the driver side wall relative to the vent hole as viewed from a side of the driver side wall.

  • Patent number: 9050942
    Abstract: An airbag of an airbag apparatus includes a vent mechanism. The vent mechanism includes a vent hole, a belt member including a cover portion for covering the vent hole and two connecting sections extending from both sides of the cover portion and serving as tethers, an outer panel located on an outer side of the cover portion, an inner panel located on an inner side of the cover portion and provided with an inner opening. The vent hole is formed on the outer panel. The connecting sections are run through the guide section so as to move toward the vent hole and let the cover portion loosen and open the vent hole when an occupant side wall of the airbag catches an occupant and moves toward a vehicle body side wall. The guide section also holds the connecting sections such that the connecting sections serve as the tethers.
