  • Patent number: 10875487
    Abstract: A side airbag device stored in a side support of a vehicle seat includes an airbag module having an airbag with first and second chambers and an inflator and a webbing partially covering the airbag module. The first chamber is deployed toward a front side of the side support and the second chamber accommodates the inflator therein and is deployed at an inner side with respect to the first chamber. The webbing extends from a rear side of the airbag module along an inner side surface of the airbag module, passes through a pad of the side support along a first path so as to reach an outside of the side support, and further extend along an outer surface of the side support and reach proximately a front edge of the side support when viewed in horizontal cross section of the airbag module from above.

  • Patent number: 10829080
    Abstract: A side airbag apparatus which allows a reduced amount of base fabric and, enables gas to flow efficiently inside the cushion. An inflator (110) supplies gas, a cushion (104) in which base fabrics are formed into a bag shape and inflates and deploys to protect an occupant (118) during a vehicle emergency, a base fabric joint portion (120) which is provided to join main panels 108a and 108b of the cushion (104) in a linear manner and partitions the cushion (104) into a rear chamber (114), a front chamber (116), and an opening (123) provided midway along the base fabric joint portion (120). The base fabric joint portion (120) includes vent forming portions 125a and 125b arranged in two rows which extend from both ends of the opening (123) towards the front chamber (116) or rear chamber (114) and form a projecting vent (124).

  • Patent number: 10717403
    Abstract: A curtain airbag device that allows easy recognition and correction of twisting of an airbag during attaching. The curtain airbag device can be stored in a compact manner during transportation. The curtain airbag device including an airbag that is disposed along a roof side rail of a vehicle interior, and that can deploy so as to cover a window portion on a side face of the vehicle interior, the curtain airbag device further including a cover that covers the airbag, at least, in a part of the folded or rolled airbag in the longitudinal direction. The cover is formed of a pliable fabric material of polymer fibers, and maintains the shape of the rolled-up airbag through mutual fusion of at least a part of the polymer fibers. A high stiffness portion harder than other portions and formed during the fusion of the cover is provided in the cover extending in the longitudinal direction of the cover.

  • Patent number: 8414014
    Abstract: A curtain airbag device for a vehicle having a lightweight, simplified, and inexpensive structure can prevent a curtain airbag from being caught by a pillar garnish when the airbag is deployed and inflated, and can restrict the deployment direction of the airbag. The curtain airbag may have sub-chambers formed therein that are folded together with the curtain airbag, and disposed adjacently thereto. The sub-chambers have a communication path formed therein that communicates with the curtain airbag. The curtain airbag is provided with tab cloth strips for supporting and fixing the curtain airbag. The tab cloth strips have an attachment section formed thereon and an annular binding section that binds together the curtain airbag and the sub-chambers. The binding section is provided with a tearing section to be torn when the curtain airbag is deployed and inflated and an anchoring section anchoring the airbag to the vehicle body side.

  • Patent number: 7832760
    Abstract: A vertical cell is formed in a forward inflation section of an airbag. The vertical cell extends in a vehicle height direction at the rear of a pillar, and communicates through a bottom end of the vertical cell with a horizontal cell. When the inflation section is deployed, the folded horizontal cell or the lower side part of the airbag is pulled back toward the passenger compartment with respect to the side window opening. Accordingly, the horizontal cell deploys to an area below a bottom edge of the side window opening or a beltline in the passenger compartment on the inner side of a front side door.

  • Patent number: 7806433
    Abstract: A supplemental inflation part is formed in a portion of an upper-end side inflation section of an airbag, the portion overlapping a B-pillar garnish. The supplemental inflation part has a semicircular shape that forms a push-out part. Folding the push-out part allows the upper-end side inflation section to be inflated largely at the initial stage of deployment of the airbag. Thus, the airbag is pushed toward the passenger compartment with greater force upon its deployment. Therefore, a terminal part of a headliner that covers the folded airbag is largely opened so that the airbag deploys smoothly downward along the side of the vehicle body in the passenger compartment without interference from the top end of the B-pillar garnish.

  • Patent number: 7597348
    Abstract: An airbag is formed from fabric layers joined at a seam, and gas generator inflates the airbag by means of gas expelled from the gas generator's insertion end which has been inserted into the airbag. A gas guide is formed in the airbag in order to direct gas from the gas generator into the airbag and includes a pouch-shaped gas guide member in which are formed gas injection nozzles and an attachment orifice. The insertion end of the gas generator is inserted into the attachment orifice with the gas injection nozzles facing an interior of the airbag. A convex-shaped seam is included where the fabric layers are joined, and is disposed in opposition to the gas guide member. The gas guide member comes into contact with the convex-shaped seam as a result of the pressure of the flow of gas from the gas generator through the gas guide member.
