Description

  The present invention relates to a steering support member structure for an automobile that can improve the rigidity of a steering support member body and prevent vibrations of the steering support member body.

  10 and 11 show an example of a steering support member structure conventionally used in an automobile. The instrument panel 100 includes a steering support member 101 disposed on the back side of the instrument panel 100. FIG. Is assembled. The steering support member 101 is attached to support the steering column, and is attached between the front pillar portions 102 provided on the left and right of the front portion of the vehicle body. A plurality of brackets 103, 104 and 105 extending obliquely downward are attached to the steering support member 101, and the instrument panel 100 is supported via these brackets 103, 104 and 105.

  In this conventional example, the bracket 103 is fixed to the floor tunnel 106, and the lower members 107 are attached to the brackets 104 and 105. The lower member 107 is provided with a large number of mounting holes 108, and an assembly component such as a glove box 109 or a radio that is assembled to the instrument panel 100 is fixed to the mounting holes 108. The glove box 109 is fixed to the lower member 107 with a bolt 111 via a support bracket 110.

  As related prior art, there are JP-A-5-213098, JP-A-2-258430, JP-A-4-130585, and JP-A-59-158557.

However, according to the conventional automobile steering support member structure, there is no fixation around the center portion of the instrument panel 100. Therefore, when a heavy object such as a radio is attached, vibration may occur. Moreover, the deformation | transformation at the time of shaping | molding of the center part lower part side of the instrument panel 100 was not able to be performed. For this reason, when there is a deformation at the time of molding, this is not a problem in a car of a passenger car system because it can be hidden by the floor console.
Further, the center portion of the steering support member 101 may be bent into a trapezoidal shape due to the layout of the heater and the like. In this case, the vibration of the steering support member 101 becomes larger and the rigidity may be lowered. Furthermore, the glove box mounting portion of the instrument panel may be deformed in the vehicle width direction with the vibration of the steering support member 101.

  The present invention solves the above-mentioned problems, improves the rigidity of the steering support member main body, can prevent vibrations generated in the steering support member main body, and can improve the assembly with the instrument panel. An object of the present invention is to provide a steering support member structure.

In order to solve the above problems, the present invention supports a steering column on a steering support member main body supported on both sides of a vehicle body via a steering column hanger, and a heater and a substantially central portion of the steering support member main body. In order to avoid interference, a pair of bent portions that are bent upward in a substantially trapezoidal shape or substantially U-shape are provided, whereby a pair of the bent portions bent upward from the steering support member main body. In the steering support member structure of the automobile that forms the lower ends of both sides of the
Each of the lower end portions on both sides is welded with a belt-like bracket that reinforces the bent portion and supports the vehicle equipment, and another belt-like bracket is joined to each of the lower end portions on both sides. One of the band-shaped bracket or the other band-shaped bracket at one lower end of the bent portion of the support member to the band-shaped bracket or the other band-shaped bracket at the lower end of the other bent portion Are connected to each other by an extension portion of the bracket to form a U-shaped bracket, and the front surface of the instrument panel in the longitudinal direction of the vehicle body is supported through the U-shaped portion of the bracket.
In addition, the present invention provides the belt support member according to the present invention, wherein one of a pair of lower end portions on both sides of the bent portion of the steering support member is welded to one of the other strip-shaped brackets. The welded belt-like bracket or one of the joined other belt-like brackets is connected to each other by an extension of the bracket to form a straight-line bracket, and the straight-line bracket is The front surface of the vehicle body equipment in the longitudinal direction of the vehicle body is supported.

  As an effect of the present invention, since a plurality of brackets are provided at the lower end of the bent portion of the steering support member main body, the rigidity can be improved.
