[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cross beam for supporting a steering column of an automobile.

[0002]

2. Description of the Related Art A cross beam, which is disposed at the front of a vehicle cabin at right angles to an axle, supports a steering column, an instrument panel, and the like, improves the rigidity of the vehicle body, and particularly improves the rigidity of the vehicle from the side. It has a function to improve the reaction force against the impact force. FIG. 4 shows a conventional cross beam and a mounting structure thereof. A vehicle body 10 includes a dash side inner panel 12, a front pillar inner panel 14, a floor panel 16, and the like. Between the dash side inner panels 12 arranged on both sides of the vehicle body, pipe-shaped cross beams 20 are fixed via brackets 22 and 24. A steering support bracket 30 is fixed to the cross beam 20 via a mounting portion 31, and the steering column is supported by a steering column connecting portion 32.

The front console bracket 40 has an upper part attached to the cross beam 20 by a bracket 42 and a lower part fixed to the floor panel 16 via a bracket 44. An instrument panel is attached to the front console bracket 40 via a connecting portion 46. The cross beam 20 is a straight tube, and its axis is orthogonal to the dash side inner panel 12. In the cross beam of this shape, the distance between the axis of the cross beam 20 and the axis of the steering column becomes large. In order to fill this distance, it is necessary to increase the size between the mounting portion 31 of the steering support bracket 30 to the cross beam 20 and the steering column connecting portion 32. For this reason, the steering support bracket 30 becomes large and causes an increase in weight.

In another example of the conventional cross beam shown in FIG. 5, a pipe-shaped cross beam 50 has a curved portion 52,
54 are formed. Both ends of the cross beam 50 are fixed perpendicularly to the dash side inner panel 12 of the vehicle body 10 via the brackets 22 and 24 in the same manner as the mounting structure of the cross beam 20 in FIG. In this cross beam 50, the mounting position of the steering support bracket 30A can be brought closer to the vehicle interior (the rear side of the vehicle body). Therefore, the distance between the attachment part 31 to the cross beam 50 and the steering column coupling part 32 can be shortened, and the steering support bracket 30A can be reduced in size and weight. Similarly, the front console bracket 40A also includes an upper mounting portion 42.
Can be simplified. The pipe-shaped cross beam structure is disclosed in Japanese Utility Model Laid-Open No. 59-75360,
It is disclosed in, for example, JP-A-3-67378.

SUMMARY OF THE INVENTION The present invention provides a more rigid cross beam and a mounting structure for the cross beam.

[0006]

The cross beam according to the present invention is formed of a cylindrical metal tube, and has a steering support bracket for supporting a steering column and a front console bracket disposed in the center of a vehicle cabin. And a bent end portion for mounting, in which the end on the side to which the steering support bracket is fixed is bent at a right angle toward the front of the vehicle.

[0007]

Since the straight portion of the cross beam is disposed behind the automobile, the steering support bracket and the steering column can be brought close to each other. Therefore,
Sufficient strength can be obtained with a small and lightweight steering support.

FIG. 2 is a sectional view taken along line II-II of FIG. The vehicle body 1 includes a dash side inner panel 12, a front pillar inner panel 14, a floor panel 16, and the like. Cross beam 10
Reference numeral 0 denotes a pipe-shaped member having a straight portion 105 and a curved portion 102 having a substantially 90 degree angle formed on the driver's seat side, and an end portion 110 extending forward of the vehicle body. End 110
Is fixed to the dash side inner panel 12 on the driver's seat side via a bracket 114. Cross beam 100
Is opposite to the dash side inner panel 12 on the passenger seat side, and is fixed to the panel 12 by the bracket 124.

The straight portion 105 is provided with the steering support bracket 31A.
Since the straight portion 105 of the zero is located rearward of the vehicle as compared with the portion fixed to the dash side inner panel 12, the distance between the cross beam mounting portion 31 of the steering support bracket 30A and the steering column connecting portion 32 is short. As a result, the size and weight of the steering support bracket 30A can be reduced. Similarly, the front console bracket 40A, whose upper end is fixed to the linear portion 105 of the cross beam 100, reduces the distance between its upper mounting portion 42 and the connecting portion 46 of the instrument panel 60, as shown in FIG. It is possible to reduce the size and weight.

FIG. 3 is a sectional view taken along the line II-II of FIG. 1, in which a dash side outer panel 18 is disposed outside the dash side inner panel 12 and a door 70 on the driver's seat side is mounted via a door hinge 80. Indicates the status. Door 7
Numeral 0 has an outer panel 72 and an inner panel 74, and is rotatably supported by a door hinge 80 via a bracket 84 and a pin 82. The other end of the door hinge 80 is a fastener 8
6 supports the dash side outer panel 18. The door 70 has an inner cover 76 attached inside the inner panel 74. The door 70 is closed in the direction of arrow C. In the case of a side collision, an impact force is applied to the vehicle body in the direction of arrow C.

The cross beam 100 of the present invention has an end 110 bent at a right angle, and this end 110 supports the dash side inner panel 12 from the inside. With this configuration, the strength against the impact force due to the collision is improved. Therefore, even if the weight of the door 70 alone or the door hinge 80 is reduced, it is possible to maintain sufficient strength of the entire vehicle body.

[0012]

[Effect of the invention] The cross beam of the invention is as described above.
Since the mounting portion of the straight pipe on the driver's seat side is bent forward at a right angle, there is only one bent portion and the rigidity is high. Since the straight section can be brought closer to the cabin,
The distance from the steering column is shortened, and sufficient rigidity can be obtained with a small bracket. Therefore, vibration control and the like are easy. Similarly, the structure of the front console bracket is simplified, and the mounting structure is improved. In the mounting portion on the driver's seat side, since the axis of the pipe is attached in parallel with the dash side inner panel, the rigidity of the vehicle body against impact from the side can be improved.
