  • Patent number: 11820313
    Abstract: An airbag includes a main inflation portion to be deployed and inflated at an outer side of the upper body of an occupant, and an auxiliary inflation portion disposed at a position adjacent to an inner side of the main inflation portion and to be deployed and inflated at an obliquely front outer side of a head portion. In the airbag whose deployment and inflation are completed, a maximum dimension in a facing direction in which an outer main body portion and an inner main body portion of the auxiliary inflation portion face each other is smaller than a dimension in a direction orthogonal to the facing direction. The auxiliary inflation portion has the outer main body portion as a joining area, and is joined to the main inflation portion in the joining area, in a state of being in communication with the main inflation portion.

  • Patent number: 11708047
    Abstract: An airbag device includes an airbag, a blocking member that can adjust an exhaust hole of the airbag to a blocked state and an opened state, a coupling member, and a holding and releasing unit, which maintains a state of blocking the exhaust hole by holding the coupling member. When the holding and releasing unit releases the holding of the coupling member, the blocking member inverts in such a way as to be fed out from an inner peripheral face side of the airbag to an outer peripheral face side through the exhaust hole owing to being pressed by inflating gas, and causes inflating gas to be discharged from a through hole formed between leading end regions of outer peripheral edges of a first panel portion and a second panel portion in the blocking member and a communication hole communicating with the exhaust hole.

  • Publication number: 20230174012
    Abstract: An airbag device includes an airbag having an exhaust hole and a flap member that can close off the exhaust hole. The flap member includes a flap main body and a coupling member. The leading end of the coupling member is coupled with an opening/closing control device. The flap main body closes off the exhaust hole from an inner peripheral face side of the airbag. A width on the base portion side is set to be greater than a width of the exhaust hole. Whole of the base portion side is joined to the peripheral edge of the exhaust hole in the airbag. The flap main body covers the exhaust hole in a region between straight lines that connect one end each of a joint region on the base portion and a region on the leading end to which the coupling member is caused to be coupled.

  • Publication number: 20230143871
    Abstract: An airbag includes a main inflation portion to be deployed and inflated at an outer side of the upper body of an occupant, and an auxiliary inflation portion disposed at a position adjacent to an inner side of the main inflation portion and to be deployed and inflated at an obliquely front outer side of a head portion. In the airbag whose deployment and inflation are completed, a maximum dimension in a facing direction in which an outer main body portion and an inner main body portion of the auxiliary inflation portion face each other is smaller than a dimension in a direction orthogonal to the facing direction. The auxiliary inflation portion has the outer main body portion as a joining area, and is joined to the main inflation portion in the joining area, in a state of being in communication with the main inflation portion.

  • Patent number: 11318904
    Abstract: An occupant protection device which is configured to protect an occupant seated on a seat, includes a seat belt, an airbag, and an inflator configured to supply inflation gas to the airbag. The airbag has a bag shape formed of a flexible sheet body, the airbag is folded and stored in a storage part provided in a lap belt, the airbag is inflated so as to project toward a front upper side when the inflation gas flows into the airbag, and the airbag has a substantially triangular prism shape whose axial direction is substantially aligned with a left-right direction so as to include a leg abutting surface which is capable of abutting an upper surface of a leg of the occupant and an upper body restraining surface which is capable of restraining the occupant from a chest to a head, when the airbag is completely inflated.

  • Publication number: 20100092432
    Abstract: [Problems] To provide a novel use of multipotential stem cells originating in a fat tissue. [Means for Solving Problems] It is intended to provide a cell preparation which contains multipotential stem cells originating in a fat tissue and is usable for an ischemic disease, impairment of renal function, wound, urinary incontinence or osteoporosis. As the multipotential stem cells originating in a fat tissue, use is made of cells which proliferate in the case of centrifuging cells separated from a fat tissue and culturing the thus sedimented cells (an SVF fraction) under low-serum conditions. In an embodiment, a cell preparation containing the SVF fraction is provided.
