Patent number: 8220828Abstract: A column-mounted knee airbag device in which a knee airbag can be correctly deployed even when the position of a steering column has changed due to a telescopic function. The column-mounted knee airbag device is equipped with a knee airbag folded inside a column cover covering a steering column main body having a telescopic function, and an inflator that generates gas when a vehicle impact is detected or predicted. The knee airbag opens an airbag door of a column cover by deployment pressure when supplied with gas, and deploys between an instrument panel and the knees of a driver. Gas ejection holes that supply gas from the inflator to the knee airbag are disposed, when viewed from the side with the steering column in a state positioned furthest to the front due to a telescopic function, further to the rear than the instrument panel in the vehicle front-rear direction.Type: GrantFiled: February 17, 2009Date of Patent: July 17, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Osamu Fukawatase, Akiyoshi Sanada

Patent number: 8141453Abstract: When a steering column contracts in order to absorb shock, interference between a column cover and a lock apparatus is suppressed, and a shock-absorbing stroke of the steering column is obtained. When a steering column contracts in order to absorb shock as a result of an input load equal to or greater than a predetermined value, a column cover that covers a rear end side of steering column, performs a stroke, together with a movable side region, relative to an outer tube (a fixed side region) of steering column, to which is fixed a lock apparatus. At this time, a side wall portion of column cover, which is positioned further to a vehicle rear than lock apparatus, enters between lock apparatus and outer tube of steering column, thereby suppressing interference between column cover and lock apparatus.Type: GrantFiled: January 5, 2009Date of Patent: March 27, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Osamu Fukawatase, Akiyoshi Sanada

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: 7997610Abstract: A knee airbag device includes an airbag module and an airbag door. The airbag module, which is provided inside a column cover that covers the rear end portion of a steering column, includes a gas generation device that generates gas when a collision occurs, and a knee airbag that is inflated and deployed from a folded state when the knee airbag receives the gas from the gas generation device. The airbag door, which is provided in the lower portion of the column cover, is opened when the inflation pressure of the knee airbag is equal to or higher than a predetermined value. When the knee airbag is deployed, at least a portion of the airbag door is positioned between an interfering object that is positioned in an area on the side of the column cover, and at least a portion of the knee airbag.Type: GrantFiled: February 28, 2008Date of Patent: August 16, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Osamu Fukawatase, Kenji Imamura, Akiyoshi Sanada, Kazuaki Bito, Yuichi Adachi

Patent number: 7988185Abstract: The knee-protecting airbag apparatus includes an airbag folded and housed in a lower area inside the column cover. The airbag pushes and opens a door section on the column cover upon deployment. When the door section is thus opened, a door of the door section blocks off an allowance gap formed between an outer circumference of the column cover subjected to position adjustment and a lower area of a peripheral region of an installation opening on a dashboard for installing the column cover by locating a rear edge region of the door to abut on a rear side of the dashboard or the lower area of the peripheral region of the installation opening on the rear side of the dashboard.Type: GrantFiled: September 27, 2007Date of Patent: August 2, 2011Assignees: Toyoda Gosei Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Yuichi Adachi, Kazuaki Bito, Osamu Fukawatase, Tomoyuki Moro, Kenji Imamura, Akiyoshi Sanada
