乗員である。FIG. 9 is a cross-sectional view showing a state in which an impact force is applied to the conventional side door described in the above publication, and a conventional door impact absorption structure 100 is an outer panel 101, an inner panel 102 and a door lining 103. The side door 104 has a three-layer structure, and the shock absorbing member 105 is disposed on the door lining 103 side. Reference numeral 106 is an impact bar, and the impact bar 106
Reinforces the outer panel 101. Reference numeral 107 is a shoulder impact absorbing member, 108 is a seat back, and 109 is an occupant.

やすい。However, since the conventional impact absorbing member 105 has a relatively large distance from the impact bar 106, the impact bar 106 absorbs the impact even if the side door 104 is pushed inward by an impact. Member 105
It takes time to come into contact with. Therefore, a time lag is likely to occur from the collision to the deformation of the shock absorbing member 105.

けたことを特徴とする。In order to solve the above-mentioned problems, the first aspect of the present invention is to form a shock absorbing member with a first shock absorbing member and a second shock absorbing member which is more rigid,
On the other hand, an opening is formed in an inner panel of a door having a three-layer structure of an outer panel, an inner panel, and a door lining, the first shock absorbing member is on the door lining side, and the second shock absorbing member is on the outer panel side. In addition, the shock absorbing member is attached by penetrating the opening so that the receiving portion provided on the second shock absorbing member is inside the inner panel.

れて衝撃エネルギーをより効率よく吸収する。Since the second shock absorbing member having higher rigidity than the first shock absorbing member is arranged on the outer panel side as described above, the distance between the outer panel and the shock absorbing member can be reduced. Therefore, when the door is deformed inward by the impact, the outer panel comes into contact with the second impact absorbing member immediately after the first impact absorbing member moves inward and collides with the occupant. Accordingly, even if the first impact absorbing member comes into contact with the occupant, the first impact absorbing member does not escape to the outside, so that the first impact absorbing member is sufficiently deformed and crushed to absorb the impact energy more efficiently.

ル３に固定する。The second impact absorbing member 8 extends in the vehicle width direction and has a lattice-like rib 8a having a larger wall thickness than the rib 7a.
A rib 8a is formed on the outer circumference of the rib 8a. Second
Since the thickness of the ribs 8a of the shock absorbing member 8 is larger than that of the ribs 7a, the shock absorbing member 8 has higher rigidity than the first shock absorbing member 7, and the second shock absorbing member 8 has the opening 3 of the inner panel 3.
Since it penetrates through a and projects to the outer panel 2 side, the distance between the second impact absorbing member 8 and the impact bar 11 of the outer panel 2 becomes smaller. The collar portion 8b is fixed to the inner panel 3 with screws 9 ...

FIG. 4 is a cross-sectional view showing a state in the initial stage of impact of the first embodiment according to the present invention, in which the side door 5 is pushed inward by the impact force F due to a side collision and the first impact absorbing member 7 moves inward. And collide with the occupant 13. However, in the early stage of the impact, the impact bar 11 of the outer panel 2 has not yet contacted the second impact absorbing member 8, so the deformation amount of the first impact absorbing member 7 is small.

い）。FIG. 4 is a sectional view showing a state after the impact of the first embodiment according to the present invention. The side door 5 is pushed further inward after a lapse of time from the initial stage of the impact, but as shown in FIG. , The second shock absorbing member 8 and the impact bar 11
Since the distance between the first shock absorbing member 7 and the first shock absorbing member 7 moves inward and collides with the occupant 13, the impact bar 11 of the outer panel 2 contacts the second shock absorbing member 8.
Therefore, the first impact absorbing member 7 does not escape to the outside and is sufficiently deformed and crushed, so that the first impact absorbing member 7 efficiently absorbs the impact energy and protects the occupant 13 from the impact force. Since the second shock absorbing member 8 has high rigidity, the second shock absorbing member 8 is not crushed (deformed) much even if the impact bar 11 comes into contact with the second shock absorbing member 8.

１３を衝撃力から保護する。FIG. 5 is a graph showing the relationship between the impact force and the amount of deformation of the first impact absorbing member according to the first embodiment of the present invention, where the horizontal axis is the deformation time of the first impact absorbing member and the vertical axis is. The impact force F is shown, the solid line curve shows the first embodiment, and the broken line curve shows the conventional example. In the case of the first embodiment, as described with reference to FIGS. 3 and 4, the impact bar 11 of the outer panel 2 does not contact the second impact absorbing member 8 at the initial stage of impact, so the amount of collapse of the first impact absorbing member 7 is large. (Deformation amount) is small,
At approximately the same time as the impact (after the lapse of T 1 hours from the initial impact), the impact bar 11 of the outer panel 2 causes the second impact absorbing member 8 to move.
Abut. Therefore, the first impact absorbing member 7 does not escape to the outside and is sufficiently deformed and crushed, so that the impact energy is more efficiently absorbed by the first impact absorbing member 7 and the occupant 13 is protected from the impact force.

小さい。On the other hand, in the case of the conventional example, the second shock absorbing member 8
Since the distance between the impact bar 11 and the impact bar 11 is large, the impact bar 11 of the outer panel 2 does not come into contact with the second impact absorbing member 8 until a relatively long time (T 2 ) elapses from the initial stage of impact. From the initial stage of impact to T 2 hours, the first impact absorbing member 7 escapes to the outside, so that the deformation amount of the first impact absorbing member 7 is small.

る。As described above, by reducing the distance between the second impact absorbing member 33 and the impact bar 11 of the outer panel 2, the door impact absorbing structure 30 of the fourth embodiment is similar to the first embodiment. (1) The impact energy is more efficiently absorbed by the impact absorbing member 32 to protect the occupant 13 from the impact force. The door shock absorbing structure 30 includes a shock absorbing member 31, a first shock absorbing member 32, and a second shock absorbing member 33.
By dividing into and, it can be easily manufactured.

衝突時の衝撃から保護する。The present invention has the following effects due to the above configuration. According to the first aspect, since the second shock absorbing member having higher rigidity than the first shock absorbing member is attached so as to be located on the outer panel side, it is possible to reduce the distance between the outer panel and the shock absorbing member. Therefore, when the door is deformed inward by the impact, the outer panel comes into contact with the second impact absorbing member immediately after the first impact absorbing member moves inward and collides with the occupant. Thus, even if the first impact absorbing member comes into contact with the occupant, the first impact absorbing member does not escape to the outside, so that the first impact absorbing member is sufficiently deformed and crushed to more efficiently absorb the impact energy and impact the occupant during a side collision. Protect from.
