本発明は自動車が歩行者と衝突した際に歩行者の負傷の
度合を軽減するようにした自動車用７−ドに関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a 7-door for a vehicle that reduces the degree of injury to pedestrians when a vehicle collides with a pedestrian.
近年の自動車事故の激増にともない、自動車の対人衝突

あるという問題点があった。With the rapid increase in car accidents in recent years, the safety of cars against collisions with other people is becoming increasingly important. Normally, when a pedestrian hits the front of a car, they are first thrown onto the hood of the car, and then hit the windshield and front pillars. By the way, this front pillar is a sharp part of the car body's strength member, so if a pedestrian collides directly with this front pillar, they will be seriously injured, and if their head hits this part, it can lead to fatal injuries. There was a problem.
本発明の目的はこのよう力従来の自動車における問題点
を解決し、対人衝突に対する自動車の安全性をより高め

衝突することを防止するようにしている。In order to achieve this object, in the present invention, the hood that covers the upper front of the automobile is divided into a pillar-side hood near the front pillar and a hood body, an interference material is provided on the back side of the pillar-side hood, and this pillar-side hood is rotated. When an impact force is applied to the front of the vehicle, the pillar-side hood rotates to cover the front of the front pillar, thereby preventing pedestrians who collide with the vehicle from directly colliding with the rigid front pillar. I'm trying to prevent it.

離するように適切な値に設定する。Next, the operation of this device will be explained. When a car collides with a pedestrian and is swept off by the front bumper and collides with the front end of the hood body 4, the load applied to the front end of the hood body 4 is transmitted to the bracket 10 via the pusher 7e. ) The hood main body 4 and the pillar-side hood 5 move backward (8) against the biasing force of the spring 18. As a result, the pin 9b is removed from the lock groove ?b, and the pin 12b is removed from the lock groove 100.
After this, the lever 9 rotates clockwise and the pin 9b is attached to the side 7C.
, and the hood main body 4 moves upward. At the same time, the pusher 7e moves along the guide 10a to flip up the pillar-side hood 5 and rotate it clockwise. As a result, the pillar side hood 5 stands upright as shown by the solid line in FIG. 8, and finally moves to the position 5' shown by the dashed line to cover a portion of the front pillar of the vehicle body. As a result, even if a pedestrian who collides with the front of the car and is thrown up collides with a part of the front pillar, the busy side 7-door 5 covers this part.
Since the object collides with the interference material 14 attached to the back surface of the object, the impact can be alleviated and damage to the human body can be minimized. In addition, when opening the hood normally, from the state shown in FIG. 2, the hood body 4 and the pillar side hood 5 are rotated together around the shaft 81 by raising the tip of the hood body 4 upward to open the hood. be able to. The strength of the spring 13 is set to an appropriate value so that the locking mechanism does not disengage during normal opening and closing of the hood (K(4)) and the lock disengages only in the event of a collision.

う効果が得られる。As detailed above, the automobile hood of the present invention has a structure in which when a rearward load exceeding a set value is applied to the front end of the hood, a part of the hood with an energy absorbing material attached to the back side flips over and covers the front pillar. Therefore, in the event of a collision between a vehicle and a pedestrian, if a pedestrian is thrown up and his or her head reaches part of the front pillar, the interference material that covers the front of the front pillar can absorb the energy and prevent the collision. This has the effect of significantly reducing the degree of injury to pedestrians.

Further, the mechanism for reversing the pillar-side hood is not limited to the above-described embodiment, and may be reversed using, for example, a motor and a link.
