この発明は、バンパ構造に係り、特にバンパの
品質を経時保持することができるバンパ構造に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bumper structure, and particularly to a bumper structure that can maintain the quality of the bumper over time.
従来のバンパ構造としては、第１図と第２図に
示すような構造が知られている。 As a conventional bumper structure, structures as shown in FIGS. 1 and 2 are known.

のである。 The bumper structure shown in FIG. 1 has an energy absorber 2 formed in a resin foam or honeycomb shape disposed on the front side of an armature 1 formed in a closed cross-sectional structure, and this energy absorber 2 is placed above and below the armature 1. The end portion is held by a resin fascia 4 secured to the upper and lower surfaces of the armature 1 with bolts and nuts 3.

ある。 In addition, the bumper structure shown in FIG. 2 has an open section structure for the armature 1 in order to improve the efficiency of introducing outside air into the engine room (not shown), and a horizontal shelf 5 is formed on the upper part of the armature. The rear upper part 2a of the energy absorber 2 is placed on the section 5, and the energy absorber 2 is held by the fascia 4 which is fixed to the armature 1 with a clip 3'.
しかしながら、かかる従来のバンパ構造にあつ

なわれ易いと共に衝突時のエネルギー吸収特性を
低下させるという不具合を有していた。 However, in such conventional bumper structures, the lower surface portion 2b of the energy absorber 2
is only supported by the fascia 4, so when a downward light load G is applied from the upper part of the fascia 4, the lower surface of the fascia 4 cannot sufficiently support the light load G and bends downward. As a result, the energy absorber 2 slides downward on the smooth front wall 1a of the armature 1, which tends to impair the appearance quality of the bumper as a whole and reduces the energy absorption characteristics in the event of a collision. It had a problem.
この発明は、かかる現状に鑑み創案されたもの
であつて、その目的とするところは、軽衝突荷重
に対するエネルギー吸収性能を劣化させることな

る。 This invention was devised in view of the current situation, and its purpose is to prevent the energy absorber from being easily deformed by downward loads without deteriorating the energy absorption performance against light collision loads. The present invention aims to provide a bumper structure that can maintain its appearance quality over time.

保持するように構成したものである。 In order to achieve this object, in the present invention, an energy absorber is disposed on the front side of the armature, and this energy absorber is held by a fascia whose upper and lower ends are fixed to the upper and lower surfaces of the armature. In the bumper structure, the armature is bent stepwise toward the front of the vehicle body to form horizontal shelves at the middle and lower ends of the armature, and energy absorbers are placed on the upper and lower horizontal shelves. It is configured to be placed and held.
次に、第３図以下に示す実施例にもとづき、こ
の発明を詳細に説明する。 Next, the present invention will be explained in detail based on the embodiments shown in FIG. 3 and below.
第３図は、この発明の第１実施例に係るバンパ

る。 And the armature 10 configured in this way
An energy absorber 2 formed in a resin foam or honeycomb shape is disposed on the front side of the second member 12, and the rear side of the energy absorber 2 is
The outer shape of the second member 12 of the armature 10 is the same as that of the second member 12.
placed on the upper horizontal shelf 12a of the
is placed on the lower horizontal shelf portion 12b of the second member 12. Note that the lower horizontal shelf portion 12b of the second member 12
The tip is formed short so that the bumper's energy absorption performance against light collision loads does not deteriorate.

帰する。 Therefore, in the bumper structure according to this embodiment, the energy absorber 2
Since the rear upper part 12a and the lower end part 2b are held respectively, even if a light downward load G is applied to the upper surface of the fascia 4 and the energy absorber 2 is compressively deformed downward. However, the energy absorber 2 is supported by the upper horizontal shelf part 12a and the lower horizontal shelf part 12b of the armature 10, which is a rigid body, and is supported in such a manner that the compressive deformation load is distributed between them. Therefore, the load applied to the lower surface of the fascia 4 becomes small and bending deformation is prevented, and the light load G is removed without causing the energy absorber 2 to slide downward and become deformed. Afterwards, it returns to its current position.
