  • Patent number: 12090944
    Abstract: An occupant protection device protects an occupant seated on a seat, in which an airbag is held in a holding body disposed in a periphery of a hip portion of the occupant. The airbag has a bag main body, and a conduit portion that causes an inflating gas discharged from an inflator to flow into the bag main body. The bag main body is held in the holding body as a completely folded body, folded using a front-rear reduction folding such that a width dimension in a front-rear direction is reduced from a preliminary folded bag. The completely folded body is formed by a lower side rolled region, formed by a lower side region of the preliminary folded bag being wound from a lower edge side, being stacked on an upper side rolled region, formed by an upper side region of the preliminary folded bag.

  • Patent number: 12083978
    Abstract: An occupant protection device includes a seatbelt, an inflator, an airbag and a tether. The seatbelt has a lap belt portion that restrains a waist portion of an occupant. The inflator discharges an inflating gas. The airbag is provided in the lap belt portion, and includes a bag main body portion, which receives the occupant by inflating owing to the inflating gas being supplied, and a conduit portion, which is connected to the inflator, guides the inflating gas discharged from the inflator to the bag main body portion, and causes the inflating gas to flow into the bag main body The tether links the conduit portion and a side wall portion, of a left side wall portion and a right side wall portion of the bag main body portion when inflation is completed, on a side separated from the inflator in a left-right direction.
