摘要： An airbag for knee protection includes at the center in a left and right direction of the upper edge an accommodation recess that recesses downward for accommodating an underside of the column cover. An outer wall of the upper region of the airbag is comprised of a panel material that is doubled on a turn crease that extends straightly through the panel in a left and right direction and forms the upper edge of the airbag. The airbag further includes beneath the turn crease and in the vicinity of the center in a left and right direction of the upper panel and above the thickness regulating tether a connecting member that approximates the driver-side wall and column cover side wall of the airbag to each other so as to provide the accommodation recess. The connecting member is arranged to form a communication passage between the connecting member and the turn crease that allows inflation gas to flow through in a left and right direction.

摘要： 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. The opening is closed by a lid.

摘要： The knee-protecting airbag apparatus includes an airbag module and a mounting bracket for fixing the airbag module on a vehicle body. The mounting bracket is provided with a mounting hole that is adapted to be fastened to a mounting seat of the vehicle body. The airbag module includes a retaining lug for fixing the airbag module tentatively on the vehicle body. When the retaining lug is engaged with a periphery of a retaining hole of the vehicle body, a rearward rotation moment is generated to rotate the airbag module about the engaging point of the retaining lug and periphery of the retaining hole, so that a pressing plane of the airbag module formed above the retaining lug abuts on and gets supported by a receiving plane formed on the vehicle body such that the mounting hole of the mounting bracket is positioned on a fastening location of the mounting seat of the vehicle body.

摘要： PROBLEM TO BE SOLVED: To provide a knee-guard air bag that can easily be produced and can be inflated with reduced lateral non-uniformity even when an inflation gas flows from one of right and left parts on an upper-stream side in an unbalanced manner. SOLUTION: A knee-guard air bag 30 has, at a center of an upper edge 30a in a transverse direction thereof, a receiving recessed portion 41 that is recessed downward to receive a lower face 5a of a column cover 5. A peripheral wall of the air bag on a side of the upper edge is formed of an upper panel material 56 having a folded portion 56a that is folded in front and behind to make a linear folding line across the entire upper edge in the transverse direction thereof. Under the folded portion 56a near the center of the upper panel material in the transverse direction thereof and above a thickness defining tether 46, a connection material 50 is placed so as to form the receiving recessed portion 41 and arrange a driver-side wall 31 and a cover-side wall 32 close to each other. The connection material 50 is placed to provide a communication part 42 through which the inflation gas can flow transversely, between the connection material 50 and the folded portion 56a in the air bag.

摘要： Rapidly constraining the knees of a driver, even for a steering column structure with plural obstructions projecting below the rear end side of the steering column, while also suppressing to a great extent, or preventing, any detriment to column collapse operation during a frontal collision. The steering column 12 is fixed to the vehicle body side with a lower bracket 46, an upper bracket 44 and a housing 48, and a combination switch 68 is disposed at the rear end side of an inner tube 36. Lower portions 48A, 70A are disposed in a state so as to protrude below a column tube 26 and face each other, so that an airbag module 64 is installed in an installation space 74 formed between the two portions. A module case 54 is manufactured from a fabric, and the airbag module 64 is attached at a position in the vicinity of the combination switch 68 through a rear attachment bracket 76. Consequently, there is no detriment to collapsing operation of the column tube 26.

摘要： PROBLEM TO BE SOLVED: To reduce the cost by eliminating a sub wire harness, and to miniaturize a column cover in a knee airbag device mounted on a column in which an inflator is transversely arranged with respect to the axial direction of a steering column. SOLUTION: An opening part 44K for work for connecting a connector 72 of a wire harness 70 extending from a steering column side to a connector 68 is formed in a sidewall part 44S of a lower cover 44 (a column cover 14) opposite to the connector 68 for wiring provided on an end of an inflator 18. By using the opening part 44K for a working space, the connector 72 of the wire harness 70 is easily connected to the connector 68 of the inflator 18 transversely mounted in the axial direction of the steering column. The opening part 44K is closed by a lid 76 after connection of the wire harness 70. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering device provided with a non-rotary airbag module which can be installed independently from rotation of a steering wheel. SOLUTION: The steering device includes the steering wheel and a steering column that are connected by gear to transmit torque of the steering wheel to the steering column side under a condition where the same are offset from each other. An airbag module received in a steering wheel hub part of the steering wheel is independently mounted such that it is not rotated together with the steering wheel by using an offset torque transmission structure of the steering wheel and the steering column. Such configuration allows deployment of a cushion having an asymmetrical optimum shape configured to avoid pressing a chest of a passenger. As the airbag module is not rotated, the design visibility of a logo can be significantly improved. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种具有非转动安全气囊模块的车辆转向装置，其可以独立于方向盘的旋转而被安装。解决方案：转向装置包括方向盘和转向柱，转向柱通过齿轮连接，以在彼此偏移的条件下将方向盘的转矩传递到转向柱侧。容纳在方向盘的方向盘轮毂部分中的气囊模块被独立地安装，使得它不通过使用方向盘和转向柱的偏移扭矩传递结构与方向盘一起旋转。这种构造允许布置具有非对称最佳形状的衬垫，其被配置为避免按压乘客的胸部。当安全气囊模块不旋转时，可以显着地改善标志的设计可视性。版权所有（C）2009，JPO＆INPIT
