構造に係るものである。 Therefore, in this invention, when the elastic bumper installed on the front and rear parts of a vehicle such as an automobile is of the so-called soft fascia type, the bumper cover is attached to the bumper reinforcement via the edge attachment part. The invention also relates to a bumper cover structure that is attached to a body through a mounting flange, and in particular, a part that is integrally molded with the bumper cover at the base of the mounting flange on the body side is attached to the bumper cover side through a notch. This relates to an elastic bumper cover structure that absorbs expansion and contraction caused by thermal deformation.

取付フランジ６を介して行う様にされていた。 That is, as shown in FIG. 1, a bumper cover 1 made of urethane elastomer is attached to a bumper reinforcement as a back-up beam material (not shown) via reinforcement mounting portions 2, 2' provided at the upper and lower edges in the figure. It is installed through bolt holes 3, 3, . It was supposed to be done.
ところで、該バンパカバー１は表皮材であるた
め、外気、太陽熱等による加熱冷却を受け易く、
従つて、第２図矢印に示す様に膨脹Ｔ、収縮Ｐを
不可避的に生ずる。 By the way, since the bumper cover 1 is a skin material, it is easily heated and cooled by outside air, solar heat, etc.
Therefore, expansion T and contraction P inevitably occur as shown by the arrows in FIG.

収する様にしていた。 The mounting parts 2 and 2' for the bumper reinforcement are mounted on the long sides, so the expansion and contraction are restricted, but the flange 6 on the body side mounting part is a type of spot mounting, so the expansion and contraction cannot be restrained. Therefore, the mounting flange 6 is made as long as possible to absorb expansion and contraction.

が発生して審美性を損うという難点があつた。 However, increasing the length of the mounting flange 6 has the disadvantage of increasing costs in terms of materials and molding, and also has the disadvantage of lowering the mounting strength.
There was a problem in that this caused the appearance of blemishes, impairing the aesthetics.

吸収することが出来ないという不具合がある。 In order to deal with this, there is a device such as the earlier application No. 55-2293 (Japanese Utility Model Publication No. 56-103350), but in this device, the bumper reinforcement mounting part is located at the inner intermediate part of the long bumper face. Since notches are formed on both sides of the body, there is a problem in that it is a kind of long-side attachment and cannot sufficiently absorb the amount of thermal expansion in the notches on both sides.

じない優れた効果が奏される。<Effects of the invention> As described above, according to this invention, in the body-side mounting flange of the bumper cover of a soft fascia type elastic bumper, a notch is provided in the bumper cover body at the base of the mounting flange. By doing so, the body mounting flange can be shortened and actually made longer. Therefore, even if the bumper cover expands and contracts due to thermal deformation, the mounting flange does not expand or contract due to torsion. As a result, an excellent effect is achieved in that no distortion or the like due to deformation occurs on the outer surface of the bumper cover.
しかも、該バンパカバーも当該切欠部に於て部
分的にも伸縮、変形が吸収されるため、その点か
らも歪が生じない効果もある。 Moreover, since the bumper cover also partially absorbs expansion, contraction, and deformation at the notch, there is also an effect that distortion does not occur from this point of view.

る。 Since the body mounting flange is spaced apart from the bumper reinforcement mounting portion, the amount of thermal expansion and contraction can be absorbed by the torsion of the body mounting flange, resulting in distortion due to deformation on the outer surface of the bumper cover. This has the excellent effect of preventing
又、取付フランジの長さも短かく出来るため設
計長も短かく、剛性低下も防げ、材料歩留りも良
くコストダウンも企れるメリツトもある。 In addition, since the length of the mounting flange can be shortened, the design length is also short, preventing a decrease in rigidity, improving material yield, and reducing costs.
そのため、耐久性も良く、基部に破損も生ぜ
ず、メンテナンスも不要である利点もある。 Therefore, it has the advantage that it has good durability, does not cause damage to the base, and does not require maintenance.
