Patent number: 6644687Abstract: In a head-protecting airbag apparatus where an airbag body inflated in a curtain configuration is mounted in a folded state along a roof side rail across at least a center pillar, the airbag body includes an upper portion folded in a bellows, and a lower portion subjected to one of turning-back performed toward an occupant compartment inner side and rolling-up performed towards the occupant compartment inner side. Accordingly, even when there is a vehicle occupant compartment inner side protrusion such as a slip joint in a vehicle, the airbag body is inflated and expanded so as to cover the vehicle occupant compartment inner side protrusion from the above or ride on the same. As a result, the lower portion of the airbag body is hard to be caught up by the vehicle occupant compartment inner side protrusion, thereby improving a expanding performance of the airbag body.Type: GrantFiled: March 22, 2002Date of Patent: November 11, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Etsuji Saito, Minoru Chida

Patent number: 6361069Abstract: A head-protection air-bag device includes a head-protection air-bag body that can be mounted in a folded state along a roof side rail, and is deployed like a curtain so as to cover at least a center pillar from the inside of a vehicle compartment. A deployment-direction regulator (e.g., a projecting portion of a center-pillar garnish) that regulates the deployment direction of the head-protection air-bag body toward the inside of the vehicle compartment is provided at a position above and adjacent to an interior projection of the vehicle compartment such as a slip joint at the center pillar.Type: GrantFiled: December 4, 2000Date of Patent: March 26, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Etsuji Saito, Minoru Chida, Hiroshi Hasegawa, Katsuya Shimazu

Patent number: 6254123Abstract: A structure for mounting a head-protecting airbag body which inflates in the form of a curtain at least along a roof side rail across a B pillar is provided with an airbag body expansion direction restricting member which is disposed on the roof side rail in the vicinity of a upper end portion of a B pillar garnish covering the B pillar and has a guide wall extending toward the upper end portion of the B pillar garnish, and moving restricting portions which are disposed on the upper end portion of the B pillar garnish and the airbag body expansion direction restricting member and engage each other when a side collision occurs so as to restrict movement of the upper end portion of the B pillar garnish. When a vehicle body is deformed upon a slide collision, the upper end portion of the B pillar garnish attempts to move in a vehicle occupant compartment inner direction.Type: GrantFiled: July 29, 1999Date of Patent: July 3, 2001Assignee: Toyota Jidosha Kabushiki KaishaInventors: Norio Urushi, Yoshiharu Furukawa, Hiroshi Ishiyama, Minoru Chida, Etsuji Saito, Kenichi Nakajima
