Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a replacement steering hub mechanism that enables a steering wheel of a vehicle, which is equipped with an airbag in a driver's seat, a passenger seat, etc., as standard equipment, to be replaced with a steering wheel suitable for competition.

[0002]

[Prior art]

 Recently, automobiles are equipped with airbags in the driver's seat, passenger seat, etc. as standard equipment. However, problems arise when they are used as vehicles for competition such as rallies and races.

That is, in general, a driver of a competition vehicle is required to replace a genuine steering wheel with a steering wheel having a slightly smaller diameter and a thicker grip than a genuine steering wheel due to the necessity of severe driving operation. To do.

In such a case, since the steering wheel equipped with the airbag cannot be manufactured in terms of space, the steering wheel will be replaced with a sporty steering wheel which is not equipped with the airbag. If the steering wheel is removed and replaced, the failure diagnosis circuit becomes inoperable, and even if a trouble occurs, the airbag in the passenger seat will not operate and other inconveniences will occur.

[0005]

[Problems to be solved by the device]

 Here, the present invention intends to provide a replacement steering hub mechanism capable of avoiding the occurrence of troubles in the failure diagnosis circuit (for example, turning on / off of a monitor lamp and deactivating of a passenger airbag). Is.

[0006]

[Means for Solving the Problems]

 In other words, the present invention proposes a boss for mounting a steering wheel of this kind, in order to replace the steering wheel, which is standardly equipped on the steering hub with an airbag module, with a steering wheel suitable for a competition vehicle such as a rally or a race. A replacement steering hub mechanism consisting of a combination of a member that has a built-in resistance circuit similar to that of the airbag module side and an alternative component that includes an airbag module dummy harness that can be connected to the harness connector to which the airbag module is connected. It is a proposal.

[0007]

[Embodiment of the invention]

 FIG. 1 is an exploded perspective view of each part of a boss 1 which constitutes a part of the mechanism of the present invention, and FIG. 2 is a perspective view of an alternative component 2 which constitutes another part of the mechanism of the present invention.

First, in the boss 1 shown in FIG. 1, 3 is a boss body, 4 is an inner cover, 5 is a boss cover, and 6 is a horn ring. First, the second alternative component 2 includes a member 7 having a built-in resistance circuit similar to the circuit on the airbag module side, and an airbag module dummy harness 8 electrically connected to the member 7.

FIG. 3 is a perspective view around the dashboard of the vehicle before the genuine steering wheel 9 is exchanged, in which the airbag module 10 has already been removed.

Next, the nut (not shown) that secures the genuine steering wheel 9 is loosened, the steering wheel 9 is removed, and the boss 1 is mounted instead. In the detached state, as shown in FIG. 4, the horn harness 12 and the harness connector 13 project from the spiral cable 11. In this figure, 14 indicates a shaft.

When mounting the boss 1, the boss cover 5 is once removed from the boss body 3, and the boss body 3 is fastened to the shaft 14 with a nut 15 as shown in FIG. 6 described later. To do.

In FIG. 5, after the airbag module dummy harness 8 of the alternative component 2 is connected to the harness connector 13, the alternative component 2 is attached to the outer peripheral portion of the boss body 3 as shown by an imaginary line in FIG. Wrap and fix appropriately.

Next, the boss cover 5 is mounted on the boss body 3, and as shown in FIG. 6, the replacement steering wheel 16 is fastened to the screw hole 17 of the boss body 3 via the screw 18. In addition, 19 shows a horn button in FIG.

[0014]

[Effect of the invention]

 According to this invention, when the airbag module 10 and the genuine steering wheel 9 are removed, the circuit on the side of the airbag module 10 can be replaced by the alternative component 2 of the invention, so that no trouble occurs in the failure diagnosis circuit. It can be safely used as a replacement for the desired steering wheel without having to cause it, and can be returned to a genuine steering wheel equipped with an airbag module if necessary.
