上記衝撃力の少なくとも一部を吸収することができる。Therefore, when a bumper face of a traveling vehicle collides with a pedestrian or the like, the impact force is transmitted to the sheet metal stay via a bumper hose, and the bent portion of the sheet metal stay in the bent line shape is further bent to cause plastic deformation. ,
At least a part of the impact force can be absorbed.

小さく構成されている。According to a second aspect of the present invention, there is provided a bumper holding device for a vehicle according to the first aspect, wherein the sheet metal stays are arranged at an interval vertically, and the upper sheet metal stay is connected to the lower sheet metal stay. The bent portion has a lower strength than the sheet metal stay.

なる。Therefore, when the bumper face of the traveling vehicle collides with a pedestrian or the like and the impact force causes the sheet metal stay to be plastically deformed at the bent portion, the strength of the bent portion of the upper sheet metal stay becomes lower. Because it is smaller than the stay,
The upper part of the bumper face supported by the upper sheet metal stay via the bumper hose is displaced toward the vehicle body side more than the lower part of the bumper face supported by the lower sheet metal stay via the bumper hose. It will be easier.

On the other hand, the lower sheet metal stays 11 and 11 'bent upward in the form of a broken line are disposed substantially in the longitudinal direction of the vehicle, and the front ends thereof are fixed to the bumper line hose 3 by welding or bolts, and the rear ends thereof.

効果的に緩和することができる。Therefore, the bumper face 2 of the traveling vehicle collides with the leg of the pedestrian, and the impact force is applied to the bumper line hose 3.
When the sheet metal stays 10, 11, 11 'are transmitted to the sheet metal stays 10, 11, 11' through the broken line, the sheet metal stays 10, 11, 11 'are easily plastically deformed at their bent portions.
As illustrated by the dotted lines, each sheet metal stay 10, 1
Each of the sheet metal stays 1 is plastically deformed at the bent portion.
The front ends of the bumpers 0 and 11, that is, the bumper face 2 and the bumper hose 3 are displaced relative to the vehicle body-side members such as the bumper beam 5 and the front end cross member 6 by distances S and S ′, respectively, to the rear of the vehicle. As shown by the hatched portions in FIG. 3, a considerable portion of the impact force is absorbed, so that the impact on the pedestrian's leg can be effectively reduced.

低減させることができる。Moreover, in this case, the sheet metal stays 10 and 1 attached to the upper and lower sides of the bumper hose 3 respectively.
Since the strength of the bent portion of the upper sheet metal stay 10 is smaller than the bent portions of the lower sheet metal stays 11 and 11 ', the bent portion of the upper sheet metal stay 10 responds to the impact force. The bumper face 2 supported by the bumper hose 3 is more easily displaced toward the rear of the vehicle than at the lower part thereof, and therefore, is generally bent more greatly than the bent parts of the stays 11 and 11 ′, and is therefore easily deformed. The displacement distance S is larger than the displacement distance S ′, and the pedestrian colliding with the vehicle receives the front bumper 1
Therefore, it is possible to reduce the possibility of being urged upward, and to go under the vehicle body.

おそれがない長所がある。The upper sheet metal stay 10 is bent downward, the lower sheet metal stays 11 and 11 'are bent upward, and the upper sheet metal stay 10 and the lower sheet metal stay 1 are bent.
Since the vertical distance from 1, 11 'is set appropriately,
The bent portions of the sheet metal stays 10, 11, and 11 'are bent without interfering with each other in the bumper face 2 due to the impact force, and there is an advantage that the bent portions do not protrude up and down of the bumper face 2.

なストロークを確保することができる。Further, the right and left ends of the bumper face 2 have a relatively large camber angle, but the outer end of the front end cross member 6 is bent rearward of the vehicle, so that the bumper line hose 3 supporting the bumper face 2 can be used. Between the left and right ends and the outer end of the front end cross member 6, a stroke necessary for plastic deformation of the lower sheet metal stay 11 'disposed at that portion can be secured.

The stroke required for plastic deformation can be easily secured by changing the mounting angle with respect to the bumper line hose 3 or the like with the lower sheet metal stay 11 ′ disposed between the end and the sideways sideways. .

With respect to the rearward displacement distance, the amount of plastic deformation of each of the sheet metal stays 10, 11, 11 'can be reduced to adjust the shock absorption characteristics of each of the sheet metal stays 10, 11, 11' due to the plastic deformation, or Needless to say, the present invention can be applied to a rear bumper in the same manner as the above embodiments.

効果的に緩和させることができる。According to the bumper holding device for a vehicle according to the first aspect of the present invention, at least one impact force against the bumper face is caused by plastic deformation in which a bent line-shaped bent portion of the sheet metal stay is further bent. Since the parts are absorbed, the impact on the pedestrian's legs and the like can be effectively reduced with a simple configuration.

減させることができる。In the bumper holding device for a vehicle according to the second aspect of the present invention, since the strength of the bent portion of the upper sheet metal stay is smaller than that of the lower sheet metal stay, the impact force on the bumper face is reduced. As a result, the upper part of the bumper face supported by the upper sheet metal stay is more easily displaced toward the vehicle body-side member than the lower part of the bumper face supported by the lower sheet metal stay, so that a pedestrian or the like collides with the bumper face. Can be reliably reduced under the vehicle body.
