開昭57−13354号参照）。 This device includes a skin 1 made of resin, an armature 2 connected to the vehicle body side of the skin 1 to support the skin 1, and an energy absorbing member 3 made of foamed resin interposed between the skin 1 and the armature 2. , and a bumper stay 5 that connects the armature 2 to the vehicle body 4, and the armature 2 has a closed cross-sectional structure in which an armature outer 2a on the skin 1 side and an armature inner 2b on the vehicle body 4 side are combined. ,
Further, the bumper stay 5 is coupled to the armature inner 2b (see, for example, Japanese Utility Model Application No. 57-13354).

る。 Incidentally, in recent years, automobile bodies have been required to have more expanded trunk space as part of demands for greater product appeal and usefulness of automobiles, and for this reason, the floor panel 4a of the automobile body 4 has been lowered, and the rear panel has been lowered. 4b is extended further rearward. On the other hand, the bumper device is required to be placed at a certain height for practical and legal reasons.

題点があつた。 And to expand the trunk space,
As shown in FIG. 5, if the expanded portion of the armature mounting portion 5b is made small, it will not be possible to effectively support the armature inner 2b up to the upper part. When an external force is applied to the vehicle due to a collision, etc., the external force due to the collision is applied to the upper part of the armature outer 2a, whereas the reaction force from the vehicle body 4 is mainly applied to the lower half of the armature inner 2b. As a result, the armature 2 becomes easily deformed as shown by the broken line in Fig. 5, and the collision resistance performance decreases. Therefore, it is necessary to increase the thickness of the bumper stay and the armature to strengthen the bumper stay. There was a problem that this resulted in an increase in cost and weight.

（実施例）
以下、本発明の実施例を図面に基づき詳細に説
明する。(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.
第１図は、本発明車両用バンパ装置の一実施例
を示すものであり、図中従来装置と同様の部分を
同一符号にて示す。 FIG. 1 shows an embodiment of the vehicle bumper device of the present invention, and in the figure, parts similar to those of the conventional device are designated by the same reference numerals.
表皮１は、バンパの外観形状をなし、かつその

する。 The skin 1 is integrally molded from resin so that it has the external appearance of a bumper and has a substantially U-shaped longitudinal section. A flange is provided at a position that is not visible from above the opening side end. Also, armature 2
The armature outer 2a on the outside of the vehicle body and the armature inner 2 on the vehicle body side are formed by forming a steel plate into a substantially U-shaped cross section and providing a flange around the steel plate.
By joining the flanges with b, a closed cross-sectional structure is created.

のエネルギー吸収部材３を充填する。 Then, as shown in FIG. 2, the flange of the skin 1 is joined to the flange of the armature 2 to fix the skin 1 to the armature 2.
The space between the armature 2 and the armature 2 is filled with an energy absorbing member 3 made of a foamed resin that relieves the impact force applied to the skin 1 due to a collision or the like by deforming itself and transmits it to the armature 2.

It is used with the cross-sectional opening side facing downward, and one end thereof corresponds to the inner shape of the armature outer 2a, and expands greatly upward and slightly expands downward to form the armature joint portion 7a.
Then, flanges are provided at the upper, lower and side ends of the armature coupling portion 7a, respectively, and these flanges are connected to the upper wall of the armature outer 2a,
Most of the armature joint part 7a is accommodated in the armature 2 by being joined to the inner surfaces of the lower wall and the side wall, respectively, and the part that cannot be accommodated and the unexpanded part of the bumper stay 7 are connected to the armature 2. The armature 2 is inserted through the hole 2d provided in the gusset inner 2a, which has a reinforcing portion formed in a stepped manner in the surrounding area.
protrude outside. Furthermore, a reinforcing member 8 having a U-shaped cross section and fitting into this portion is joined to the inner surface of the unexpanded portion of the bumper stay 7.

とする。 For example, when the bumper device of this embodiment configured as described above is installed at the rear of the vehicle body, the bumper stay 7 is extended into the rear side member 9 that is joined to the bottom surface of the floor panel 4a of the vehicle body 4. The missing parts shall be inserted and joined.

ルーム内へ逃がす必要もなくすることができる。 In the above-described embodiment having such a structure, most of the extended portion 7a of the bumper stay 7, which can sufficiently effectively support the upper end of the armature outer 2a, is housed within the armature 2, and the vehicle body 4 and the bumper stay are connected to each other. Since interference with the armature outer 2a is prevented, even if force is applied to the upper part of the armature outer 2a due to a collision or the like, this force can be directly and sufficiently supported by the bumper stay 7, preventing deformation of the armature 2. This can be extremely effectively prevented, and it is also possible to eliminate the need for the joint between the floor panel 4a and rear panel 4b of the vehicle body 4 to escape into the trunk room.

装着上有利となることは言うまでもない。 Therefore, according to the above embodiment, even in a bumper device in which the bumper stay is installed with the bumper stay offset from the armature, the trunk space can be greatly expanded while ensuring sufficient collision resistance without increasing the weight, thereby increasing the usefulness of the automobile. You can fully demonstrate your sexuality. It goes without saying that if the device of this embodiment is mounted on the front of the vehicle body, the engine room will be enlarged, which will be advantageous for mounting the radiator, air conditioner condenser, etc.

Since the amount of inward protrusion can be suppressed, when applied to the rear bumper, it is possible to eliminate the need for the joint between the floor panel and rear panel of the vehicle body to escape to the inside of the vehicle body, thereby freeing up trunk space without reducing collision resistance. It can be expanded significantly.
