DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a bumper guard mounted on the front of a front bumper of a motor vehicle.

[0002]

2. Description of the Related Art Conventionally, as bumper guards for automobiles,
As described in Japanese Utility Model Laid-Open Publication No. 4-46957, a bumper garnish is generally attached to the front of a front bumper at two places on the left and right, and a gate-shaped guard bar made of a metal pipe is attached between these bumper garnishes.
However, in the case of the above-mentioned bumper guard, there is a disadvantage that the structure becomes large and the weight becomes large due to the use of the metal pipe.

[0003] In recent years, there have been automobiles in which a bumper guard made of a resin component is attached to the front of a front bumper. This bumper guard is composed of a plurality of front guards extending in the vehicle width direction, and a pair of left and right side guards disposed at both ends of the front guard. Since these parts are both resin parts, a metal pipe is used. The weight can be reduced as compared with the case. A fog lamp or the like is attached to the side guard.

[0004]

When the above-mentioned front guard and side guard are attached to a vehicle body, they are usually attached directly to a bumper with bolts or the like. However,
Since bumpers used in recent years tend to eliminate large reinforces like conventional ones, the strength of the bumper body made of resin alone is insufficient, and the gap between the front guard and the side guard is not constant. However, there is a disadvantage that the appearance deteriorates. Also, when a person sits on the front guard, the load cannot be supported by the bumper alone, and the front guard may hang down.

Accordingly, an object of the present invention is to provide a mounting structure of a bumper guard in which the dimensional accuracy of the front guard and the side guard is stabilized and the rigidity of the mounting to the vehicle body is improved.

[0006]

In order to achieve the above object, the present invention provides a front bumper made of resin and a plurality of front guards extending in the vehicle width direction and a pair of left and right side guards disposed at both ends of the front guard. In a vehicle equipped with a bumper guard consisting of: a bumper stay extending vertically and attached to the back of the bumper, and a lower end of the bumper stay is fixed to a front end of a side member extending in the vehicle longitudinal direction, while a front guard and a side guard are provided. Are connected via a bracket, and a mounting piece extending toward the rear of the vehicle body and fastened to the bumper stay is integrally formed with the bracket.

[0007] Since both the front guard and the side guard constituting the bumper guard are assembled to the bracket, the bumper guard can be assembled as a single unit, and the dimensional accuracy between these parts is stabilized. In this state, if the mounting piece of the bracket is fastened to the bumper stay, the bumper guard can be easily mounted on the vehicle body. Moreover, since the load of the bumper guard can be received by the bumper stay through the bracket, the mounting rigidity of the bumper guard is improved as compared with the case where the bumper guard is supported only by the resin bumper. Therefore, even when a load such as a passenger is applied to the front guard, it is possible to prevent the front guard from hanging down.

Further, when the bumper guard is directly attached to the side member via the reinforce, the crash allowance of the side member is reduced, which may adversely affect the collision performance. Since it is mounted only on the vehicle, there is no adverse effect on collision performance due to the addition of a bumper guard.
