Patent number: 9199601Abstract: When an inner bag is inflated inside an outer bag, impact on an occupant received by an airbag is reduced. An inner bag (30) is inflated with gas supplied from an inflator (3). A gas exhaust port (31) is formed on the inner bag (30) and allows the gas to flow from the inner bag (30) in an occupant direction (E). An outer bag (20) accommodates the inner bag (30) and is inflated with the gas supplied from the gas exhaust port (31). A restriction member restricts the inflation of a portion of the inner bag (30) to change a direction of which the gas flows out from the gas exhaust port (31) to avoid the occupant direction. The restriction member breaks during the inflation of the outer bag (20) to release the restriction of the inflation of the inner bag (30).Type: GrantFiled: October 18, 2012Date of Patent: December 1, 2015Assignee: ASHIMORI INDUSTRY CO., LTD.Inventors: Naoki Yamaji, Kazuto Tokura

Patent number: 9187058Abstract: An airbag device includes: an airbag; an inflator; a gas discharge state switching member; and a tether belt which is one example of a connecting member. The gas discharge state switching member is switched over from a gas discharge state to a gas non-discharge state by being pulled into the inside of the airbag. The tether belt connects the gas discharge state switching member and a portion of an inner peripheral portion of the airbag to each other. An arranged position of the gas discharge state switching member, a position where the tether belt is connected to the inner peripheral portion of the airbag, and a passing line of the tether belt are disposed at portions which avoid a portion of the airbag which comes into contact with an occupant in a regular posture state when the airbag receives the occupant.Type: GrantFiled: February 6, 2013Date of Patent: November 17, 2015Assignee: ASHIMORI INDUSTRY CO., LTD.Inventors: Naoki Yamaji, Satoshi Yamashita
