Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a steering device for an automobile, which is an improvement of a mounting structure of a steering column.

[0002]

[Prior Art]

 As shown in FIG. 8, a steering column 1 of an automobile is generally supported by two points, a holding member 3 having an upper side attached to a steering ring hanger 2 and a support plate 5 having a lower side attached to a pedal bracket 4. There is. The holding member 3 that holds the upper side of the steering column 1 and the support plate 5 that holds the lower side of the steering column 1 are as shown in FIG. 9 (see FIG. 10 for the holding member 3). The notch parts 6 and 7 are formed in the parts to be attached to the steering wheel 4. The steering column 1 is fixed to the steering hanger 2 and the pedal bracket 4 by fitting the bolt 8 into the notch parts 6 and 7 and tightening it with the nut 9. ing.

The holding member 2 for holding the upper side of the steering column 1 is attached in such a manner that the holding member 2 is pulled out in the front direction of the vehicle when the steering column 1 is moved when the occupant collides with the steering wheel 10. 2 is attached so that the opening of the notch 6 faces the occupant side. Further, since the support plate 5 that holds the lower side needs to hold the steering column 1 and absorb the collision energy in the absorbing portion 11 when the occupant collides with the steering wheel 10 as described above, the opening portion of the cutout portion 7 is provided in the vehicle. It is attached toward the front side of. As a result, at the time of a collision, the holding member 2 comes off, the supporting plate 5 holds the steering column 1, and the absorbing portion 11 absorbs the collision energy. In addition, 12 is a primary side shaft of a steering column, 13 is a gear box, 14 is a cowl, and 15 is a dash panel.

As a steering device, there is one disclosed in Japanese Patent Application Laid-Open No. 60-169365. In the one disclosed in this publication, a V-shaped notch groove that widens in the vehicle width direction toward the rear of the vehicle is provided in the bracket of the steering column so that the steering column can be mounted even when an occupant strikes the steering wheel from an oblique direction. The fitting member to be supported and the column bracket are easily separated from each other.

[0005]

[Problems to be solved by the device]

 In the above-described conventional technique, in the case of a frontal collision of the vehicle, the support plate may be pulled out from the bolt of the pedal bracket to the driver side due to the backward movement of the gear box (as indicated by arrow b in FIG. 8). If the support plate is pulled out and there is an input from the occupant side, there is a problem that the absorption unit cannot absorb this force.

In the steering device disclosed in Japanese Patent Application Laid-Open No. 60-169365, a V-shaped notch groove that widens in the vehicle width direction toward the rear of the vehicle is provided in the bracket of the steering column, so that when the vehicle collides with the column. Since the bracket and the fitting member supporting the steering column can be easily separated, the problem of the present invention aimed at preventing the support plate supporting the steering column from coming off easily is solved. It does not exist.

The present invention has been made in order to solve the above-mentioned conventional problems. By restricting the rearward movement of the support plate, the input from the occupant can be reliably received even in the case of a frontal collision of the vehicle. An object is to provide a steering device for an automobile.

[0008]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a vehicle in which a steering column is supported by a support plate attached to a pedal bracket, and the support plate is retracted to a portion located behind the support plate of the pedal bracket. Then, it is characterized in that it is integrally formed with a protrusion that abuts against this and restricts its movement.

[0009]

[Action]

 As described above, according to the present invention, since the protrusion that abuts against the support bracket is formed at the portion located behind the support plate of the pedal bracket, a force is applied to the pedal bracket side from the front due to a vehicle collision or the like. When the plate retreats, the protrusion abuts on the support plate and restricts the retreat movement, so that the support plate is prevented from coming off.

[0010]

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3, in which the same members as those in FIG. 8 are designated by the same reference numerals. FIG. 1 shows a mounting portion on a lower side of a steering column 1 of an automobile showing a main part of the present invention. The lower side of the steering column 1 is supported by a support plate 5 attached to a pedal bracket 4. The support plate 5 is L-shaped, and the pedal bracket 4 mounting side is provided with a cutout portion 7 as shown in FIG. The support plate 5 is attached by fitting the bolt 8 with the opening side of the cutout portion 7 facing forward.

At a portion of the pedal bracket 4 located behind the support plate 5, when the support plate 5 retracts, there are two protrusions 16 that come into contact with the support plate 5 and restrict the movement thereof. Is integrally formed at the bottom of the (see also FIG. 2). The protrusion 16 is formed by gradually bulging downward from the rear to the front, and has a triangular shape in a side view (see FIG. 3).

Next, the assembling of the support plate 5 to the pedal bracket 4 will be described with reference to FIGS. 4 to 6. First, the notch 7 (see FIG. 9) of the support plate 5 supporting the steering column 1 is directed toward the front of the vehicle, fitted with the bolt 8 (see FIG. 4), and moved forward to move the support plate 5 When the vertical portion moves to the position where it abuts the protrusion 16, the support plate 5 is tightened upward by the nut 9 (see FIG. 5). Then, the nut 9 is further tightened until the support plate 5 comes into contact with the lower portion of the pedal bracket 4, and the support plate 5 is closely attached and fixed to the pedal bracket 4 (see FIG. 5).

The operation of the vehicle steering system thus configured will be described below. In this embodiment, since the protrusion 16 that abuts the support bracket 5 is provided integrally with the pedal bracket 4 at a portion of the pedal bracket 4 that is located behind the support plate 5, the vehicle collides with the steering column 1 and the protrusion 16 is provided. Even if there is an input from the front direction (see the arrow a in FIG. 1) and a force for retracting the support plate 5 is applied to the support plate 5 of the pedal bracket 4, the protrusion 16 comes into contact with the support plate 5 and moves backward. As a result, the support plate is prevented from coming off.

In this embodiment, the backward movement of the support plate 5 is regulated by the protrusion 16 provided integrally with the pedal bracket 4, but this is not the case, and as shown in FIG. A step 17 may be provided on the pedal bracket 4 to which the support plate is attached, and the step 17 may restrict the backward movement of the support plate 5.

[Effect of the device]

 As described above, according to the present invention, since the projections that are provided on the rear portion of the support plate of the pedal bracket to restrict the movement of the support plate when the support plate retracts are provided integrally with the pedal bracket, as described above. Even if a vehicle collides and a force to retract the support plate is exerted via the steering column, the projection contacts the support plate and restricts its backward movement, so that the support plate does not move or come off. .. As a result, even if the steering column receives an input from the passenger side, this force can be reliably absorbed. In addition, since this protrusion is simply molded on the lower part of the pedal bracket, it is inexpensive, and the assembling performance is the same as before.
