本発明は、自動車のハンバ、特に衝撃吸収型のバンバの
構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of an automobile bumper, particularly a shock-absorbing bumper.
一般に、自動車のバンパは、車体の前、 ｌ１ｊｃα１
１１部に配設され、自動車の衝突時等に自動車に衝撃力
が加わった場合、これを吸収して乗員の安全を確保する
とともに、車体が傷付くのを防止するためのものである

設け、さらに該吸収体表面を表皮部材で覆ったものがあ
った。Generally, the bumper of a car is located at the front of the car body, l1jcα1
It is arranged in the 11th section, and when an impact force is applied to the car during a car collision, it absorbs the impact force to ensure the safety of the occupants and to prevent damage to the car body. In recent years, impact-absorbing bumpers that can improve the above-mentioned impact-absorbing ability have been manufactured, and conventionally, as described in Japanese Utility Model Application Publication No. 56-3046, the upper horizontal part and the vertical part There is one in which an absorbent body with uniform hardness is provided on both surfaces of a reinforcement part A consisting of a wall surface part, and the surface of the absorbent body is further covered with a skin member.
ところで、上記衝撃力は上記吸収体の上面水平部部分に
は、あまり作用しないものであるから、該部分には本来
吸収体を設ける必要はないものであり、従って、上記従
来のバンパでは必要以上に吸収体が設けられていること
となり、その結果、この従来例では、バンパの重量が大
きいとともにコストが高いという問題があった。しかし
ながら上記上面水平部部分に吸収体を設けない場合は、
今度は表皮部材の上面部が垂れてバンパの外観が悪化し
てしまう問題が生しる。By the way, since the impact force does not act much on the horizontal portion of the upper surface of the absorber, there is no need to provide an absorber in that portion. As a result, in this conventional example, there were problems in that the weight of the bumper was large and the cost was high. However, if no absorber is provided in the horizontal part of the upper surface,
This time, a problem arises in that the upper surface of the skin member sag, deteriorating the appearance of the bumper.
本発明は、以上のような従来の問題点に鑑みてなされた
もので、ハンパの外観が悪化することなく重量を軽減で
き、またコストも低減できる自動車のハンパ構造を提供
することを目的としている。The present invention has been made in view of the conventional problems as described above, and an object of the present invention is to provide a damper structure for an automobile that can reduce weight without deteriorating the appearance of the damper and also reduce costs. .

した衝撃吸収力を有するように、従って目的に応した重
量を有するようにしたものである。In order to achieve the above object, the present inventor has proposed that the absorber provided on the horizontal upper surface of the reinforcement member is mainly used to prevent the skin member from sagging, and to maintain the shape of the skin member. Therefore, the present invention focuses on the fact that the shock absorbing power is not so necessary.Therefore, the present invention provides a suspension structure for an automobile in which the suspension is a reinforcement member having at least a horizontal upper surface portion and a vertical wall surface portion. It consists of a skin member that covers this, and an absorbent body provided between the two members, and the absorbent body provided on the horizontal part of the upper surface is made softer than the absorbent body provided on the vertical wall part. Each part of the body is designed to have a shock-absorbing capacity appropriate to its purpose, and therefore to have a weight appropriate to its purpose.
以下、本発明の実施例を図について説明する。 Embodiments of the present invention will be described below with reference to the drawings.
