Patent number: 7384065Abstract: The knee protection airbag device (S1) includes an airbag (40) which protrudes rearward from a deployment opening of a housing upon inflow of inflation gas, and deploys upward to be located in front of knees of an occupant between a vehicular body and the occupant. The airbag (40) includes an occupant's side wall (41) and a vehicular body side wall (42). Lower end (48) side of the airbag (40) as flatly expanded with the walls (41 and 42) overlaid on each other constitutes an upstream side of inflation gas. The airbag (40) is firstly folded to bring its upper end (47) close to its lower end (48), from flat expanded state in which the occupant's side wall (41) and the vehicular body side wall (42) are overlaid on each other. Thereafter, the airbag (40) is folded to reduce its transverse width, and then is housed in the housing. The airbag (40) of the knee protection airbag device (S1) is able to deploy effectively from the start to completion of deployment for protecting the knees of the occupant.Type: GrantFiled: December 2, 2002Date of Patent: June 10, 2008Assignees: Toyoda Gosei Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Masahiro Takimoto, Tatsuya Hayakawa

Patent number: 7290787Abstract: An occupant knee protection apparatus for a vehicle includes a knee airbag 11 disposed in front of a knee portion B1, B2 of an occupant and configured to expand and deploy toward the knee portion B1, B2 of the occupant upon collision of the vehicle to thereby protect the knee portion B1, B2 of the occupant. The knee airbag 11 is attached to a panel 21 capable of absorbing energy. The panel 21 is connected to a support member of the vehicle; that is, an instrument-panel reinforcement 23, via brackets 22 capable of absorbing energy. The panel 21 is disposed in front of the knee portion B1 of the occupant at a vertical position where the knee portion B1 of the occupant can come into contact with the panel 21 when the occupant has a small build as compared with a standard build.Type: GrantFiled: February 19, 2003Date of Patent: November 6, 2007Assignee: Toyota Jidosha Kabushiki KaishaInventor: Tatsuya Hayakawa
