Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steering structure mounted on a vehicle, and more particularly to a steering structure for an airbag to which an airbag is attached.

[0002]

[Prior Art]

 As a conventional airbag steering system for mounting an airbag installed to enhance the safety of passengers when a vehicle collision occurs, there is, for example, a structure shown in FIG.

That is, 1 is a steering wheel mounted on a vehicle, and 2 is an airbag module having a bag member, an inflator and the like housed therein and a surface formed of a pad member. The reference numeral 2 is arranged and fixed to the central portion of the steering wheel 1 and inside the module mounting portion 4 which is integrally formed via the spokes 3.

Reference numeral 5 denotes respective switch units for performing operations such as audio / air conditioning control. When these switch units 5 are mounted on the outer side of the module mounting portion 4, first, the air bag module is used. 2 is removed from the module mounting portion 4 and then mounted from inside the module mounting portion 4 with mounting screws 6.

[0005]

[Problems to be solved by the device]

 However, in such a conventional airbag steering system, the airbag module is different due to the difference in the shape of the module mounting portion 4 (the shape change when the number of the spokes 3 is three and the number of the spokes 3 is four). If the shape of 2 is also changed, the shape of the air bag module 2 must be configured differently according to the number of spokes, and the work line is divided, resulting in high product cost. There was a problem that it would become.

[0006]

[Means for Solving the Problems]

 This invention was made in view of these problems in the past, and a module mounted on the module mounting portion formed in the central portion of the steering wheel is attached to the module mounting portion. With a structure that can be fixed by a fixed-shape module mounting frame, an airbag module of a single structure (shape) can be installed for any shape of steering, and an economical airbag To provide steering for vehicles.

【Example】

 The present invention will be described in detail below based on the embodiments shown in the drawings.

In FIG. 2, reference numeral 11 denotes a steering wheel mounted on a vehicle, and an airbag module mounting portion 13 for fixing the airbag module 12 is provided at a central portion of the steering wheel 11 via four spokes 14. And is provided integrally with the steering wheel 11.

The airbag module 12 includes an airbag cover 15, a bag 16, a bracket 17, and an inflator 18, which are sequentially arranged and housed in the airbag cover 15, and the airbag module 12 is the same. It is a single structure with the same structure and shape. Reference numeral 19 denotes a steering pad member that is attached to surround the outside of the airbag module 12 attached to the airbag module attachment portion 13 and is integrally connected to the steering wheel 11. The steering pad member 19 is a steering pad member. Has four spoke fitting portions 20 corresponding to the four spokes 14.

The steering pad member 19 in this embodiment is of a type in which a control switch unit for audio / air conditioning is not attached. For example, when one or two switch units are attached to the steering wheel, As shown in FIGS. 3 and 4, the switch unit 21 is fastened from the back side of the steering pad member 19 with the mounting screw 22, and the portion corresponding to the operation piece 23 of the switch unit 21 of the steering pad 19 is provided. As the thin structure 24, various steering pad members 19 are configured in advance so that the switch unit 21 can be pushed and operated from the front side of the steering pad member 19. Reference numeral 25 indicates a connector connected to the tip of the lead wire drawn out from the switch unit 21.

FIG. 6 shows a fixing means for the steering pad member 19 fixed to the steering wheel 11. The steering wheel 11 is provided with a locking hole 26 and the steering pad member 19 is locked with the locking hole 26. By providing a locking claw 27 that is locked in the hole 26, the steering pad member 19 can be detachably fixed to the steering wheel by the locking action of the locking claw 27 and the locking hole 26. is there.

In such an embodiment, the airbag module mounting portion 13 is provided at the center of the steering wheel 11, and the airbag module 12 is mounted on the mounting portion 13 and then the outside of the airbag module 12 is mounted. The steering pad member 19 is attached to the steering pad member 19 so that the gaps and the like generated between the airbag module mounting portion 13 and the airbag module 12 are hidden by the steering pad member 19. Even if there is a difference in shape between the shape of the mounting portion 13 and the shape of the airbag module 12, the appearance of the steering wheel is not impaired.

Therefore, a single production of the shape and structure of the airbag module 12 is applied to various types of steering, for example, to a steering wheel having four spokes as shown in FIG. 2, and as shown in FIG. Since the airbag module 12 can be attached to a steering wheel having the present spokes and used, the airbag module 12 can be produced in a single unit, and thus the productivity and the economical efficiency of the airbag module 12 can be improved.

Further, in this embodiment, the switch unit 21 is fixed to the back side of the steering pad member 19, and the operation piece 23 of the switch unit 21 can be operated from the front side of the steering pad member 19. Therefore, the switch unit 21 is waterproofly covered by the steering pad member 19, and as a result, the waterproof protection of the switch unit 21 is perfect.

[0015]

[Effect of the device]

 As described above, according to the present invention, in the airbag steering in which the airbag module 12 is arranged and fixed in the central portion of the steering wheel 11, the airbag module 12 stores the inflator 18, the bag 16, the inflator and the bag. The steering wheel for an airbag is formed by a cover 15 that covers the front side of the cover 15, and a steering pad 19 attached to the steering wheel 11 is attached to the front side of the cover 15. Even if the spokes and the four spokes are different from each other, it is not necessary to change the shape of the air bag module 12, and therefore, the air bag module 12 having a single structure and shape can be produced. Bag module 12 productivity and economy An effect that is enhanced can be obtained.
