ンパを提供することにある。For example, when the collision object is columnar and bent in the middle, the position far from the bending point, that is,
A lower collision requires a smaller force to generate a moment around the bending point and lowers the energy of the collision, but the energy sub-absorbing member 8 on the upper part of the bumper 1 at the time of the collision as described above. When energy is received, the force for generating the moment increases, and the energy of the collision increases, which is not preferable. Therefore, an object of the present invention is to provide an energy absorbing bumper that can reduce the energy received by a collision object during a collision.

した。According to a first aspect of the present invention, an energy absorber for absorbing collision energy is mounted on a bumper support member mounted on a vehicle body. In the energy-absorbing bumper in which the front surface is covered with a bumper skin, the energy absorber is a member having a shape in which a lower portion projects forward from an upper portion.

への衝撃を軽減する。For example, when a collision occurs with a pillar-shaped object that bends in the middle, the energy absorber is formed so that the lower part protrudes forward from the upper part, so that a position far from the bending point of the collision object becomes the collision point. Therefore, the force for generating a moment around the bending point is reduced, and the energy of the generated collision is further reduced, thereby reducing the impact on the collision object.

吸収するので、衝突時の衝撃がより小さくなる。According to a second aspect of the present invention, the energy absorber is a beam having a substantially rectangular cross section having a bottom surface and a slope. The energy absorber gradually deforms by hitting the collision object from the bottom side to the upper side of the slope, so that the energy of the collision is smoothly absorbed, so that the impact at the time of the collision becomes smaller.

FIG. 1 is an exploded perspective view of an energy absorbing bumper according to the present invention. An energy absorbing bumper 1 includes a bumper supporting member 2 mounted on a vehicle body side and an energy absorbing member mounted on a front side of the bumper supporting member 2 as an energy absorbing body. It comprises a beam 3 and a bumper skin 4 covering the front surface of the energy absorbing beam 3. When the vehicle collides with an object such as a structure or a pedestrian, the energy absorbing beam 3 absorbs the energy of the collision and reduces the impact on the object. It also reduces the impact on the vehicle.

In the present embodiment, an example in which the upper portion UP and the lower portion LO are columnar and can be bent around the shaft portion P has been exemplified.

Is immediately after the collision, (b) is after a certain time has elapsed since (a),
(C) shows a state where the time has further elapsed from (b).
In (a), immediately after the collision, the energy absorbing beam 3 of the energy absorbing bumper 1 hits the collision object S at the front end face 13 via the bumper skin 4.

物Ｓへの衝撃を軽減することができる。At this time, assuming that the vertical distance between the shaft portion P and the front end face 13 lower than the shaft portion P is L, the distance L can be substantially the same at the upper and lower portions as in a conventional energy absorber. Since it becomes larger than the one that starts to hit, the force F for generating the moment M around the shaft portion P decreases, the energy of the generated collision decreases, and the impact on the collision object S can be reduced. .

衝突物Ｓを受ける。In FIG. 2B, when a certain time has elapsed since the collision, the lower portion LO of the obstacle S rotates clockwise about the shaft portion P and tilts due to the pressing force of the energy absorbing bumper 1. Thereby, the energy absorption beam 3
Gradually absorbs the energy of the collision while deforming downward. Further, the slope 12 of the energy absorbing beam 3 gradually receives the collision object S even on the upper side. In (c), the lower part LO of the collision object S is further tilted, and the energy absorption beam 3 receives the collision object S further above the slope 12.

従って、被衝突物Ｓ、車両又はその乗員が受ける衝撃を
より小さくすることができる。As described above, as time elapses from the collision, the energy absorbing beam 3 absorbs the collision energy while gradually deforming downward, and causes the collision object S to move from the bottom surface 11 side to the upper side of the slope 12. Since it is gradually deformed by hitting, it is possible to absorb the energy of the collision smoothly and to reduce the maximum value of the impact force.
Therefore, the impact received by the collision object S, the vehicle or its occupant can be further reduced.
