Patent number: 8689924Abstract: An air-bag device in which a deployed air-bag has a complete deployment portion positioned on the longitudinally central side and having a substantially constant diameter and incomplete deployment portions positioned on longitudinally opposite end sides and having a diameter that gradually decreases in going toward a blocking member, the incomplete deployment portion has high rigidity compared with the complete deployment portion and is difficult to deform when there is a collision with a pedestrian, thus degrading the impact absorption performance, but disposing the plurality of vent holes in the incomplete deployment portion at a fixed pitch in the longitudinal direction and the circumferential direction of the air-bag enables the rigidity of the incomplete deployment portion to be lowered and the impact absorption performance to be enhanced, thereby giving uniform impact absorption performance over the entire longitudinal length of the air-bag.Type: GrantFiled: April 22, 2011Date of Patent: April 8, 2014Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Okamoto, Fumiharu Ochiai, Yuji Kikuchi, Koji Ikeda

Patent number: 8550493Abstract: An airbag (18) made of metal is disposed between an edge portion (12a) of a windshield (12) of a vehicle and an outer panel (16), projecting toward an outside of a vehicle body beyond the edge portion (12a), of a front pillar (15). Thus, it is possible to install the airbag device without making large design changes to the existing structure of the vehicle body, and to prevent the external appearance from being deteriorated by the installation of the airbag device. Further, once the airbag (18) made of metal is deployed, the airbag does not shrink. Thus, it is possible not only to reduce the weight and costs by employing an inflator (19) with a smaller volume, but also to cause the airbag to exert a stable shock absorbing capability irrespective of the difference in the timing of the collision of a pedestrian. Further, a part of the airbag (18) is a garnish part (18a) forming an outer surface of the vehicle body in cooperation with the outer panel (16).Type: GrantFiled: September 7, 2010Date of Patent: October 8, 2013Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Okamoto, Fumiharu Ochiai, Yuji Kikuchi, Koji Ikeda

Patent number: 8365857Abstract: In an airbag system, an airbag obtained by closing each of opposite end portions of a folded metal tube with an end cap is attached to an attachment surface of a front pillar, and the airbag is deployed along the front pillar with a gas produced by an inflator. Therefore, a pedestrian who collides with the front pillar can be protected by the airbag. Since the portion of the airbag, which is away from the end cap toward an intermediate part of the airbag in a longitudinal direction of the airbag by a predetermined distance, is connected to the attachment surface, which is located outside the end cap in the longitudinal direction of the airbag, with a stay being interposed in between, the difficulty in an inflation in a part of the airbag in the vicinity of each end cap, due to the end cap being pressed against the attachment surface when the airbag is inflating, is prevented.Type: GrantFiled: May 28, 2010Date of Patent: February 5, 2013Assignees: Honda Motor Co., Ltd., Autoliv ASP, Inc.Inventors: Yutaka Okamoto, Eric Drake, Bengt Pipkorn

Patent number: 8186472Abstract: A pedestrian protection airbag device is provided in which an airbag (34) having a closed cross section is formed by inflating and deploying a front outer panel (16) and a front inner panel (18) of a front pillar (15) by means of high pressure gas generated by an inflator (26). This enables the head of a pedestrian to be protected from an impact due to collision with the front pillar (15). Furthermore, since impact absorption performance is exhibited by plastic deformation of the deployed airbag (34), as long as deployment of the airbag (34) is completed before restraining the pedestrian, it is unnecessary to subsequently control the internal pressure of the airbag (34), and it becomes possible for an effective impact absorption performance to always be exhibited regardless of the vehicle speed at the time of collision or the physique of the pedestrian while simplifying the specification of the inflator (26) and reducing the cost.Type: GrantFiled: November 18, 2008Date of Patent: May 29, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yutaka Okamoto, Yuji Kikuchi, Koichi Kamiji

Publication number: 20110278087Abstract: An airbag system to protect a pedestrian includes a metal airbag and an inflator. The metal airbag is provided in a zigzag-folded state between a side end portion of a windshield of a vehicle and a front pillar projecting toward a front of a vehicle body with respect to the side end portion. The side end portion is an end portion of the windshield in a lateral direction of the vehicle body and is connected to the front pillar. The inflator is configured to generate gas to deploy the metal airbag along the front pillar. The metal airbag is folded such that a virtual line connecting each of peaks and one of valleys continuous with the peaks included in zigzag folds extends substantially in an front-rear direction of the vehicle body.Type: ApplicationFiled: April 6, 2011Publication date: November 17, 2011Applicant: HONDA MOTOR CO., LTD.Inventor: Yutaka OKAMOTO

Patent number: 7988183Abstract: Opposite end portions of an airbag made of a folded metal plate and formed into a tubular shape are capped by respective end caps and are attached to an attachment surface of a front pillar, and the airbag is deployed along the front pillar by use of gas produced by an inflator, thereby protecting by the airbag a pedestrian that collides with the front pillar. Bolts penetrating through long holes formed in the end portions of the airbag and bolt holes of the end caps are screwed to weld nuts, and thereby the end portions of the airbag are slidably supported by the end caps. Accordingly, when the airbag is deployed the long holes slide with respect to the respective bolts toward inside in a longitudinal direction of the airbag, and a tension in the longitudinal direction of the airbag is prevented from acting on a metal plate of the airbag, thereby enabling the airbag to be deployed reliably near the end caps.Type: GrantFiled: July 7, 2010Date of Patent: August 2, 2011Assignees: Honda Motor Co., Ltd., Autoliv ASP, Inc.Inventors: Yutaka Okamoto, Eric Drake, Earl Nelson
