Patent number: 8128121Abstract: In a knee airbag device mounted on a steering column, an opening that provides a workspace when a wire harness connector that extends from the steering column is connected to a wiring connector provided at one end portion of an inflator is formed in a side wall of a lower cover (or column cover) opposite the connector of the inflator. By using the opening, the connector of the wire harness may be easily connected to the connector of the inflator, which is mounted transversely with respect to the axial direction of the steering column.

Patent number: 8056922Abstract: The invention has the object of increasing workability of an attachment operation of a knee airbag module of a column-mounted knee airbag device. When fixing a knee airbag module to a lower portion outer peripheral surface of a steering column, it is possible to perform the fixing from a vehicle upper side and a vehicle rear side of the steering column, using a space between an instrument panel (interior member) at a vehicle upper side of the steering column and a combination switch provided at a rear end side of the steering column. Accordingly, when performing an attachment operation of the knee airbag module to the steering column, an operator does not have to enter from a lower side of the steering column.Type: GrantFiled: March 11, 2010Date of Patent: November 15, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tetsu Mitsuo, Akiyoshi Sanada

Patent number: 7832760Abstract: A vertical cell is formed in a forward inflation section of an airbag. The vertical cell extends in a vehicle height direction at the rear of a pillar, and communicates through a bottom end of the vertical cell with a horizontal cell. When the inflation section is deployed, the folded horizontal cell or the lower side part of the airbag is pulled back toward the passenger compartment with respect to the side window opening. Accordingly, the horizontal cell deploys to an area below a bottom edge of the side window opening or a beltline in the passenger compartment on the inner side of a front side door.Type: GrantFiled: August 28, 2007Date of Patent: November 16, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Autoliv Development ABInventors: Tetsu Mitsuo, Akihiko Narui, Mitsuo Nogami

Patent number: 7806433Abstract: A supplemental inflation part is formed in a portion of an upper-end side inflation section of an airbag, the portion overlapping a B-pillar garnish. The supplemental inflation part has a semicircular shape that forms a push-out part. Folding the push-out part allows the upper-end side inflation section to be inflated largely at the initial stage of deployment of the airbag. Thus, the airbag is pushed toward the passenger compartment with greater force upon its deployment. Therefore, a terminal part of a headliner that covers the folded airbag is largely opened so that the airbag deploys smoothly downward along the side of the vehicle body in the passenger compartment without interference from the top end of the B-pillar garnish.Type: GrantFiled: August 28, 2007Date of Patent: October 5, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Autoliv Development ABInventors: Tetsu Mitsuo, Akihiko Narui, Mitsuo Nogami
