ドである。A conventional bumper 1 will be explained with reference to FIG. In this figure, a foamed material 3 and a beam 4 made of iron or synthetic resin are arranged inside a fascia 2 that forms a bumper 1 of an automobile, and the beam 4 is attached via a mounting bracket 5. It is fixed to the crossmen halo of the car body. In addition, the one shown in FIG. 6 has only a beam 4 made of synthetic resin disposed inside the fascia 2, and like the one in FIG. 5, the beam 4 is attached to the vehicle body via a mounting bracket 5. It is fixed to the cross member 6. The beam 4 made of synthetic resin shown in FIG. 6 plays the role of two members: the foam material 3 shown in FIG. 4 and the beam 4 made of iron or synthetic resin. In the figure, 7 is an engine hood.

印のような横方向への引張力が生ずる問題点もある。In addition, the one shown in Fig. t56 has only the beam 4 made of synthetic resin assembled on the fascia 2, and although light grinding can be achieved, the deformation grinding is large, especially in the front and back directions. There are problems such as it is easy to use and does not require high performance as a bumper. Furthermore, if the vehicle collides with an object such as a wall 8, the receiving part of the bracket 5 will be pushed and deformed (see the solid line in Figure 7), and the back of the beam 4 will have a lateral direction as shown by the arrow. There is also a problem with the generation of tensile forces.

Since the beam 9 has a bead 12 formed on its rear vertical wall portion 13, the collision load can be absorbed by expanding this portion. Further, the tensile force in the lateral direction generated on the back surface of the beam 9 can also be prevented by the bead I2. Therefore, the impact load transmitted to the vehicle body side can be significantly reduced.

ことによって製作することも可能である。Next, the resin beam 9 will be explained in detail. The resin beam 9 includes an upper plate portion IO whose dimensions correspond to the width of the vehicle body, and a lower plate portion 11 parallel to the upper plate portion IO. A partition wall 14 that partitions the space into a plurality of parts is connected to the space part 13 and further surrounded by the upper plate part 10, the lower plate part 11, and the vertical wall part 13, and faces forward from the vertical wall part 13. It is made to protrude, is horizontally long, and has a length that corresponds to the length of the hamper as a whole. Then, the front part of the beam 9 formed in this way is covered with the fascia 2, and it is attached to the cross member 6 of the vehicle body via the mounting bracket 5 provided on the rear side of the vertical wall part 13 (see Figs. 3 and 4). (see), the resin beam 9 is usually obtained by integrally molding the entire resin beam, but it can also be manufactured by joining a number of cylindrical bodies.

ことができる。A car with a bumper l constructed in this way is attached to a wall 8.
When colliding with an object such as, the impact load is Facial 2
, the impact load acts to compress the beam 9 via the fascia 2 . On the front side of the beam 9, a plurality of partition walls 14 protrude forward from the rear vertical wall 13, so that the partition walls 14 increase the rigidity and become resistant to deformation in the front-rear direction, that is, crushing deformation. , the bumper l will not be significantly deformed.Furthermore, since the bead 12 is formed on the rear vertical wall portion 13 of the beam 9, this portion will expand to absorb the collision load. . Further, the tensile force in the lateral direction generated on the back surface of the beam 4 is blocked by the bead formed on the vertical wall portion 13. Therefore, it is possible to obtain a bumper 1 that is resistant to deformation in the longitudinal direction and lateral direction, and that significantly reduces the impact load transmitted to the vehicle body.

A horizontally elongated beam having a length corresponding to the length of the bumper as a whole is molded from resin by the partition wall, and the resin beam is attached to a cross member of the vehicle body via a mounting bracket at the vertical wall portion. By covering the front part of the resin beam with a fascia, the weight of the damper can be reduced, while also avoiding the weak points that conventionally had due to its light weight, namely longitudinal and lateral deformation, which are transmitted to the vehicle body. It can be formed into a bumpy shape that significantly reduces the impact load. Furthermore, since the beam disposed inside the fascia is relatively easy to shape, it also has the effect of improving productivity.
