撃吸収構造体の厚さにはおのずと限界がある。In the above conventional structure, the ribs are buckled or the cushioning material is compressed by the impact of collision,
Since the shock is absorbed at once in the range of the displacement stroke, the maximum load F received by the occupant is large, as is clear from the explanatory diagram showing the relationship between the load applied by the shock and the displacement in FIG. , Easy to receive fatal damage. Therefore, it is desirable to reduce the maximum load and enable shock absorption while maintaining the low maximum load, but since the buckling of the ribs and the compression of the cushioning material start at once and the shock absorption proceeds at the same time, the displacement stroke That is, unless the space between the base material and the surface layer is sufficiently secured, the impact load cannot be absorbed. If the distance between the base material and the surface layer is increased, the space becomes bulky and the indoor space is narrowed. Therefore, the thickness of the shock absorbing structure is naturally limited.

実質的に同一であると解する。The shock absorbing structure thus formed is
If the head is hit with a slight impact that is received when sudden braking is applied, the collision portion of the pad 6 contracts and absorbs the impact, and the contraction is immediately restored. When a head collision occurs due to a collision accident, the collision portion of the pad 6 contracts, the skin body 2 is strongly pressed against the pillar body 1 side, and the tall vertical rib 3 first buckles (FIG. 3). A). If the impact is absorbed by the buckling of the vertical ribs 3, the skin 2 is only slightly deformed, and the head is less damaged. However, when the vehicle collides head-on with an oncoming vehicle or is struck by a vehicle from the side, the impact load on the head is too large to absorb the impact only by buckling the vertical ribs 3,
Following the buckling of the vertical ribs 3, the lateral ribs 4a and 4b also buckle (a in FIG. 3). In the embodiment, since it is assumed that the head collides with the central portion of the epidermis, the vertical ribs on the central side 3
The portion 4b sandwiched by 3 buckles at substantially the same time although it is lower than the portion 4a sandwiched by the skin 2 and the vertical ribs 3,
This is because the space between the pillar body 1 and the skin body 2 is narrower in the central portion than on both sides, and theoretically, as illustrated in a, b, c of FIG. , If the load is evenly applied, the ribs 7a, 7
When the head collides from the side of the pillar, the portion 4a sandwiched between the skin body 2 and the vertical rib 3 is bent by the vertical ribs 3 and 3 because it is buckled (bent) with b and 7c. Since it is higher than the sandwiched portion 4b, the portion 4a sandwiched between the epidermis 2 and the vertical rib 3
After buckling, the vertical ribs 3 and the horizontal ribs 4a and 4b buckle in a total of three stages such that the portion 4b sandwiched between the vertical ribs 3 and 3 buckles, and the shock is sequentially absorbed. As in the above-described embodiment, the distance between the base and the skin is often not constant depending on the object to be implemented, and at locations where the difference in distance is large, ribs of the same height, contrary to the above-described embodiment, are used. Will also buckle in stages. Therefore, in such a case,
It is understood that they are substantially the same.

大荷重Ｆを低く押えることが可能となるのである。The shock load is divided into a plurality of parts as shown in FIG. 5 and is gradually absorbed while keeping the maximum load low. Thus, the shock is gradually absorbed within a limited displacement stroke. Even if the body has the same thickness as the conventional one, the maximum load F can be kept low.

As shown in FIG. 5, a cushioning material 9 made of foamed resin may be filled between the ribs 3 and 4 to enhance the shock absorbing effect.
