SUMMARY OF THE INVENTION CRT display 6
Since the brackets 7 fixed to both sides of the vehicle are fastened to the brackets 10 of the steering member 9 and are disposed so as to face the window portion 2, the occupant moves forward by inertia when the vehicle collides or the like. When a secondary collision is applied to the upper edge portion of the window portion 2, that is, the upper edge portion of the rear surface of the instrument panel 1 as shown by an arrow F in FIG. There is a possibility that the CRT display 6 may be damaged by interfering with the rear surface, that is, the upper edge of the screen side.

Therefore, the present invention relates to a CRT display and the like.
A part set substantially along the rear surface of the instrument panel is a component set in an instrument panel of a vehicle that can protect the part by avoiding mutual interference even if the instrument panel is deformed during a secondary collision. To provide a mounting structure.

[0008]

On top of the part to be arranged inside the instrument panel SUMMARY OF THE INVENTION, while projecting a high upper bracket rigid offset rearward from the rear surface of the component, the bottom of the component A plastically deformable lower bracket is protruded, and the upper bracket is fixed to an upper mounting portion formed on a secondary collision input action line on an upper part of the panel body of the instrument panel, and a lower bracket formed on the panel body. It is fixed to the mounting part.

[0009]

When a secondary collision input acts on the upper edge portion of the rear surface of the instrument panel during a vehicle collision or the like, an upper mounting portion of the panel body is provided on the secondary collision input operation line. A high-rigidity upper bracket protruding offset from the rear surface of the part is fixed to the lower part, while a plastically deformable lower bracket is protruded below the part, and this is attached to the lower part of the panel body. When the upper part of the panel body is plastically deformed, the part is fixed by the upper bracket while the distance between the upper mounting part of the panel body and the part is kept constant by the upper bracket. It pivots forward with the fixed part as a fulcrum, and mutual interference between the panel body and the components is avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described by taking a CRT display as an example of components in an instrument panel.
The same reference numerals are given to the same parts as those of the above-described conventional configuration with reference to the drawings, and the details will be described.

In FIG. 1, an instrument panel 1
Is composed of a panel body 3 and a soft pad 4 covering the outer surface thereof.
A window portion 2 for disposing the display 6 is formed, and the window portion 2 is decorated with a cluster lid 5 made of resin.

Above the window portion 2 of the panel main body 3, there is a portion where the occupant has a high tendency to make a secondary collision when the occupant moves forward by inertia at the time of a vehicle collision, that is, an arrow F at the upper edge of the rear surface of the instrument panel 1. The upper mounting portion 20 is formed to protrude rearward from the fenestration portion 2 on the secondary collision input action line indicated by. A lower mounting portion 21 is formed on the lower edge of the window portion 2 of the panel body 3.

The secondary collision input action line refers to a line direction input by a head form of a SAE or JSAE mannequin centered on a hip point (not shown).

On the other hand, an upper bracket, which is offset rearward from the rear surface and has high rigidity, for example, an upper bracket 22 formed by die-casting integrally with the display main body, is provided on the upper portion of the rear surface of the CRT display 6 so as to project upward. In addition, on the lower surface of the CRT display 6, an L-shaped lower bracket 2 made of a plastically deformable metal plate is provided.
3 is attached by bonding or the like.

The upper bracket 22 is superimposed on the outer surface of the upper mounting portion 20, and the lower bracket 23
Are superimposed on the outer surface of the lower mounting portion 21 and fixed to the screws 24, respectively, and the CRT display 6 is arranged to face the window portion 2.

In this embodiment, a steering member 9 arranged inside the instrument panel 1 in the vehicle width direction is provided.
Then, a bracket 25 whose rear end overlaps the inner surface of the upper mounting portion 20 of the panel body 3 is fixed, and the upper bracket 22 is fastened to the rear end of the bracket 25 together with the bracket 25.
Thus, the support rigidity can be secured.

In FIG. 1, reference numeral 26 denotes the steering member 9.
, An air conditioner unit arranged below, and 27 indicates the vent duct.

According to the structure of the above-described embodiment, when the occupant inertially moves forward in the event of a vehicle collision or the like and makes a secondary collision with the upper edge of the rear surface of the instrument panel 1, the upper mounting portion 20 of the panel main body 3 is moved. Is provided on the line of action of the secondary collision input F, and the CRT display 6
A high-rigidity upper bracket 22 projecting offset from the rear surface of the CRT display 6 is fixed, while a plastically deformable lower bracket 23 on the lower surface of the CRT display 6 is fixed to the lower mounting portion 21 of the panel body 3. When the upper part of the panel body 3 is plastically deformed, the upper bracket 22
With the distance between the upper mounting portion 20 of the panel body 3 and the upper edge of the CRT display 6 kept constant,
The RT display 6 pivots forward about the fixed portion of the lower bracket 23 as a fulcrum due to the plastic deformation of the lower bracket 23 as shown by a chain line in FIG.

Therefore, it is possible to prevent the panel body 3 from interfering with the CRT display 6, and
Can be prevented from being damaged.

At the time of the above-mentioned secondary collision, since the CRT display 6 rotates forward with the lower bracket 23 as a fulcrum, the plastic deformation of the panel body 3 and the bracket 25 of the steering member 9 can be performed smoothly. Since the deformation strokes of the panel body 3 and the bracket 25 can be sufficiently ensured, the collision energy absorbing effect can be enhanced.

Further, since the upper bracket 22 keeps a constant distance between the panel main body 3 and the CRT display 6, it is possible to prevent the occupant from colliding with the CRT display 6 in a secondary collision. There are advantages that can be further enhanced.

In the above-described embodiment, the assembly structure of the CRT display 6 has been exemplified. In addition to the above, other electronic parts arranged substantially along the rear surface of the instrument panel 1 and various internal parts of the instrument panel are included. Applicable to assembly of products.

[0023]

As described above, according to the present invention, even when the occupant collides with the instrument panel in the event of a vehicle collision or the like, the interval between the panel body and the component is kept constant by the upper bracket of the component. By rotating the part forward with the lower bracket as a fulcrum while avoiding mutual interference between the part and the panel body, it is possible to protect the part without damage.

In addition, since the deformation of the panel body is not hindered by the forward rotation of the part, the collision energy absorbing effect can be enhanced.

Further, the distance between the panel main body and the component can be kept constant, so that the occupant can keep the space between the panel main body and the component.
Since the next collision can be avoided, there is an advantage that the safety can be further improved.
