Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reduces the vibration of a steering wheel during idling, and absorbs an impact load in the case of a front collision of a vehicle so that the steering device is not deformed rearward of the vehicle. The present invention relates to a steering reinforcement device for an automobile.

[0002]

2. Description of the Related Art In some automobiles, dash panels (inner walls) located on both left and right sides of a vehicle compartment are connected by a reinforcing member such as a pipe, and the steering column is supported by the reinforcing member. This will be described below. In FIG. 5, 1 is an automobile, and 2 is a pipe that is a reinforcing member that connects the dash panels 3 on the driver's seat side and the passenger's side. This pipe 2 has a steering column 4
Is attached to hold the steering column 4 and the steering wheel 5 that are steering devices with good rigidity.

Both ends of the pipe 2 are dash panels 3
However, in order to make the mounting rigidity of the steering column 4 mounted on the pipe 2 and the steering shaft inside the pipe 2 sufficient, it is necessary to strengthen the related parts. .. Further, when the engine is idling, if the vibration of the engine is transmitted to the steering column 4 having a low mounting rigidity, the steering wheel 5 vibrates greatly. Therefore, the pipe 2 and the cowl portion 6 are connected by the plate-like reinforcing bracket 7 to improve the mounting rigidity of the steering column 4 and reduce the vibration of the steering wheel during idling.

However, if the plate-like reinforcing bracket 7 is mounted between the pipe 2 and the cowl portion 6, the mounting rigidity of the steering column 4 is improved, and
Although the vibration of the steering wheel 5 was reduced at the time of idling, when the vehicle collides with the front portion and the cowl portion 6 is deformed to the vehicle compartment side (rearward) and the reinforcing bracket 7 is pushed. The reinforcing bracket 7 cannot absorb this impact load, and as shown in FIG. 6, the reinforcing bracket 7 moves to the pipe 2 side together with the cowl portion 6 to deform the pipe 2, and the steering device moves to the passenger side. There was a risk of coming. This is because the reinforcing bracket 7 is plate-shaped, so that the reinforcing bracket 7 is not easily deformed (buckled) in the front-rear direction and the impact load is hardly absorbed.

Therefore, in order to solve this, the cowl portion 6
Between the pipe and the pipe 2, a Z-shaped reinforcing bracket 9 having a neck 8 as shown in FIG. 7 and a reinforcing bracket 11 having a bead 10 as shown in FIG. 8 (Japanese Patent Laid-Open No. 61-241264). (See Japanese Patent Publication). If the reinforcing bracket 9 having the constriction 8 and the reinforcing bracket 11 having the bead 10 are mounted as described above, the vehicle collides with the front portion and the cowl portion 6
When retracted, the reinforcing brackets 9 and 11 are deformed from the constricted portion 8 and the bead 9 to absorb the impact load, and the deformation of the cowl portion 6 is not transmitted to the pipe 2. The steering device does not move backward to the passenger side.

[0006]

In the prior art described above, a Z-shaped reinforcing bracket having a constriction,
The reinforcement bracket with beads is a temporary purpose to absorb the impact load at the time of a collision because the reinforcement bracket is deformed when the cowl part is deformed toward the vehicle compartment side and pushes the reinforcement bracket during a front collision of the vehicle. However, there is a balance with the reinforcing effect to improve the mounting rigidity of the steering column attached to the pipe, so increasing the rigidity of the reinforcing bracket makes it difficult for the reinforcing bracket to deform, that is, it does not collapse sufficiently. In addition, if it is crushed easily, it is difficult to improve the mounting rigidity of the steering column and it is difficult to reduce the vibration of the steering wheel.

The present invention has been made to solve the above-mentioned conventional problems. By connecting a pipe to which a steering column is mounted and a cowl portion with a wire, the rigidity of mounting the steering column is improved and at the time of idling. (EN) Provided is a steering reinforcement device for a vehicle, which reduces vibration of a steering wheel and easily deforms and absorbs an impact load at the time of a front collision of a vehicle to prevent the steering device from moving toward an occupant. With the goal.

[0008]

As a means for solving the above problems, the present invention connects a driver side dash panel and a passenger side dash panel of a vehicle with a reinforcing member,
The steering column is supported by the reinforcing member, one end of the wire is fixed to at least one of the reinforcing member and the cowl portion, and the other end of the wire is provided on at least one of the reinforcing member and the cowl portion. The wire winding member is engaged with the wire winding member, and the wire winding member is tightened to apply tension to the wire.

According to the present invention, one end of the wire is fixed to at least one of the reinforcing member and the cowl portion to which the steering column is attached, and the other end of the wire is connected to at least one of the cowl portion and the reinforcing member. Since it is engaged with the wire winding member provided in the above, it is possible to tighten the winding member. As a result, tension is applied to the wire, the reinforcing member and the cowl portion can be attracted to each other and firmly fixed, and a large rigidity can be secured to the front side of the vehicle body. It is possible to reduce the rigidity to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to FIG.
The same members as those in FIG. 1 is an automobile and 2 is a pipe which is a reinforcing member. The pipe 2 is hung and fixed between the dash panel 3 on the driver's seat side and the passenger's seat side, and the steering column 4 of the steering device is attached and fixed to the pipe 2.

A wire holding member 13 is fixed to the cowl portion 6, and one end of a wire 12 (piano wire or the like) is fixed to the wire holding member 13. Further, the other end of the wire 12 is attached to a wire winding member 14 fixed to the upper portion of the attachment position of the steering column 4 of the pipe 2 (see FIG. 2 showing an enlarged main part). This wire winding member
As shown in FIG. 3, the reference numeral 14 generally comprises a bolt screwing portion 15 attached to the pipe 2 and a bolt 16.
Then, by tightening the bolt 16 of the wire winding member 14 and applying tension to the wire 12 in the direction of the arrow in FIG. 1, the pipe 2 and the cowl portion 6 are attracted to each other by the wire 12 and firmly fixed. Will be. As a result, the mounting rigidity of the steering column 4 can be improved, and the vibration of the steering wheel 5 can be reduced when the engine is idling.

As shown in FIG. 4, even when the vehicle 1 collides with the front portion and the cowl portion 6 is deformed toward the passenger compartment (rear) side, the wire 12 bends to easily absorb the impact load at the time of collision. Therefore, the deformation of the cowl 12 is not transmitted to the pipe 2. Accordingly, the pipe 2 is not deformed, and the entire steering device, that is, the steering wheel 5 is
Also, the steering column 4 does not move to the passenger side.

Next, the operation of this embodiment will be described. One end of the wire 12 is fixed to the wire holding member 13 attached to the cowl portion 6 of the automobile, and the other end of the wire 12 is engaged with the wire winding member 14 of the pipe 2 on which the steering column 4 is mounted. The bolt 16 of the winding member 14 can be tightened. As a result, tension is applied to the wire 12. When tension is applied to the wire 12, the pipe 2 and the cowl portion 6 are attracted to each other and firmly fixed, and the mounting rigidity of the steering column 4 can be improved. In this case, the mounting rigidity can be great in the front direction of the vehicle body and small in the occupant direction.

In the present embodiment, the cowl portion 6 is provided with the wire holding member 13 for fixing one end of the wire 12, and the pipe 2 is provided with the wire winding member 14 for winding the wire 12. Instead, the wire winding member 14 may be provided on the cowl portion 6 and the wire holding member 13 may be attached to the pipe 2.

[0015]

According to the present invention, one end of the wire is fixed to at least one of the reinforcing member and the cowl portion to which the steering column is attached as described above, and the other end of the wire is fixed to the cowl portion or the reinforcing member. Since it is engaged with the wire winding member provided on at least one of the
It becomes possible to tighten the winding member. As a result, tension is applied to the wire, the reinforcing member and the cowl portion can be attracted to each other and firmly fixed, and a large rigidity can be secured to the front side of the vehicle body and a rigidity to the passenger side. Can be made smaller.

This makes it possible to improve the mounting rigidity of the steering column and reduce the vibration of the steering wheel during idling. Even if the vehicle collides with the front portion and the cowl portion is deformed rearward, the wire is bent and the impact load is easily absorbed, so that the deformation of the cowl portion is not transmitted to the reinforcing member. Therefore, there is no possibility that the steering device, that is, the steering column and the steering wheel will move to the occupant side. Further, the resonance frequency of the steering device can be changed by adjusting the tension of the wire. Further, since this reinforcing device has a relatively simple structure, it has an effect that the manufacturing cost can be sufficiently suppressed.
