Patent number: 8408596Abstract: An airbag device that may ensure an increased restraining force and a reduction of damage with respect to an occupant that is out of position or of small stature is provided. The airbag device for a passenger seat of the present invention may be disposed inside an instrument panel of a vehicle and protects an occupant inside the vehicle by inflation and deployment of an airbag when an emergency situation occurs. The airbag device includes: an airbag that is compressed into a plurality of layers in a vertical direction when not used, and inflated and deployed when an emergency situation occurs; and a restriction member that restricts the deployment of the airbag so that a deployment direction of an upper layer portion is directed toward an occupant side, wherein the upper layer portion is deployed first from among the plurality of layers of the airbag.Type: GrantFiled: August 21, 2008Date of Patent: April 2, 2013Assignee: Autoliv Development ABInventors: Takashi Matsunaga, Takeshi Ohwada

Patent number: 7681909Abstract: An airbag device according to the invention is applicable to an airbag device having an airbag that is housed in a state of being able to inflate and deploy in front of an occupant. The airbag has a center chamber positioned in the vicinity of the center on the occupant side in a deployed state, and side chambers positioned on both the left and right sides of the center chamber. Moreover the airbag is provided with a gas supply section that supplies inflation gas to inside of the side chambers, and a means for introducing inflation gas to inside of the center chamber after the side chamber. Furthermore, the side chamber has; a gas introduction space into which inflation gas from the gas supply section is introduced, an upper space that extends upward from the gas introduction space, and a lower space that extends downward from the gas introduction space.Type: GrantFiled: February 13, 2007Date of Patent: March 23, 2010Assignee: Autoliv Development ABInventors: Takashi Idomoto, Takeshi Ohwada, Yutaka Tsuchida, Hiroya Tabushi, Chihiro Ito, Yosuke Shimizu, Shinobu Yamamoto
