Description

[Detailed explanation of the idea] The present invention relates to a bumper for a vehicle.

As described in Japanese Utility Model Application Publication No. 52-52253, there is a vehicle bumper in which a thin metal protector is fixed across the top and front parts of the bumper body in order to make the appearance more beautiful than before. It is publicly known.

With this bumper, the protector can be fixed to the bumper body by hooking the protector's peripheral edge to the stepped part of the bumper body using the elasticity of the protector itself, or one peripheral part of the protector can be attached to the bumper body with bolts. At the same time, the other peripheral edge of the protector is bent onto the peripheral edge of the bumper body to fix the protector to the bumper body.

In this bumper, since the protector is made of metal, it is possible to fix the protector to the bumper body using the above-mentioned fixing means. However, if the protector is made of synthetic resin material, the above-mentioned fixing means no longer makes it possible to fix the protector to the bumper body. It cannot be fixed to the bumper body.

An object of the present invention is to provide a bumper for a vehicle in which the protector can be easily and reliably fixed to the bumper body when the protector is made of a synthetic resin material.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 1 to 3, 1 is a metal bumper body whose surface is chrome-plated or painted;
2 is the front part of the bumper body, 3 is the top part of the bumper body, 4
5 is a protector with a curved cross section made of flexible resin material;
1 is an insertion plate, 6 is a bolt, 7 is a fixing protrusion integrally formed on the back surface of the protector 4, and 8 is a pump corner guard made of synthetic resin fixed to both ends of the bumper body 1.

Note that the insertion plate 5 and bolts 6 are cast into the protector 4 when the protector 4 is molded.

The protector 4 is disposed to cover substantially the upper half of the front surface 2 and the entire top surface 3 of the bumper body 1, and extends along the entire length of the bumper body 1 in the longitudinal direction, as shown in FIG.

On the other hand, a bolt penetration hole 9 is formed on the bumper body 1 at a position opposite to the bolt 6, and a projection penetration hole 10 is further formed on the bumper body 1 at a position opposite to the projection 7.

To attach the protector 4 to the bumper body 1, as shown in FIG. 4, first insert the bolt 6 into the bolt penetration hole 9, then rotate the protector 4 clockwise and insert the protrusion 7 into the penetration hole 10. Then, the bolt 6 is tightened and the clip 11 is fitted onto the protrusion 7.

Since it is necessary to rotate the protector 4 and attach it to the bumper body 1 as described above, the protrusion penetration hole 10 is formed as a long hole in the front-rear direction.

In addition, considering the thermal expansion of the protector 4, the protrusion penetration hole 10 is
is also expanded laterally.

As described above, according to the present invention, a bolt and a protrusion are fixed to a protector, and after the bolt is inserted into a bolt penetration hole formed in a bumper body, the protector is rotated to form a protrusion in a protrusion penetration hole formed in a bumper body. Even if the protector is made of synthetic resin material, the protector can be easily and reliably fixed to the bumper body by inserting the protector into the bumper body, then tightening the bolts and clipping the protrusions.
