  • Publication number: 20240067118
    Abstract: An occupant protection device of a configuration that 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 in a state of a completely folded body folded using a front-rear reduction folding such that a width dimension in front-rear direction is reduced from a state of a preliminary folded bag. The completely folded body is formed by a lower side rolled region which is 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 which is formed by an upper side region of the preliminary folded bag.

  • Patent number: 11813999
    Abstract: An occupant protection device is such that an airbag is housed in a housing region of a lap belt portion that can be disposed on a front side of a waist portion of an occupant seated in a seat. The airbag can receive and protect an upper body of the occupant using a rear face side occupant restraining face when inflation is completed. The airbag includes an exhaust port that can discharge an inflating gas and a regulating valve mechanism that restricts a discharge of the inflating gas from the exhaust port. The regulating valve mechanism permits a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is restricted, and restricts a discharge of the inflating gas from the exhaust port when a protrusion upward of the airbag from the housing portion is not restricted.
