きくて緩衝作用が良くないと云う問題がある。<Prior art> Conventionally used shock absorbers include those with mechanical structures such as air dampers and shock absorbers, and those that absorb impact force with elasticity such as elastic cushions. Among these, the former cannot be used for small items such as protective gear, and the latter has a problem in that it has a large rebound resilience and does not have a good cushioning effect against sudden and strong impact forces.
このため特願昭59−140146号出願の明細書にお
いて開示したように、針入度100〜200のゲル物買
を吸収部材の吸収体として使用する事が提案され
ている。 For this reason, as disclosed in the specification of Japanese Patent Application No. 59-140146, it has been proposed to use a gel material having a penetration of 100 to 200 as an absorbent material for an absorbent member.

事が出来、従つて緩衝効果が頗る良好であると云
う特長がある。 In this way, a shock absorber made of gel material with a penetration degree of about 100 to 200 has extremely low rebound resilience and good internal transmission of shock waves, so it quickly disperses the applied shock and improves the overall impact. It has the advantage of being able to absorb it through deformation, and therefore has a very good cushioning effect.

163652号公報に開示されている。 Since the surface of such a shock absorber made of gel material is highly sticky, it is necessary to harden the surface of the gel material, which is the material of the absorber, to form a non-viscous skin layer. , this skin layer forming method is described in Japanese Patent Application Laid-open No. 59-30932 and Japanese Patent Application Laid-Open No. 58-1989.
It is disclosed in Publication No. 163652.

する事が困難であると云う問題がある。<Problem to be solved by the invention> Since conventional impact bodies are made of a single shock absorber as disclosed in Japanese Patent Publication No. 59-30932, it is necessary to adjust the appropriate elasticity to the shock absorber. Therefore, in order to obtain the required resiliency,
It is necessary to impregnate a gel substance into a cushioning body that has a desired shape and then harden the surface of the cushioning body, but with this method, it is said that it is difficult to individually adjust the elasticity of the cushioning body. There's a problem.

The exterior body 2 itself may have elastic restoring force and elastic buffering force, but since the cushioning body of the present invention utilizes the inelastic cushioning effect of the silicone gel material, the elasticity of the exterior body 2 is It is preferable that the silicone gel material be as small as possible so as not to impede the impact absorption effect. Therefore, it is desirable to use the exterior body 2 made of, for example, damping rubber. As such a high damping rubber material, Bridgestone Co., Ltd.'s The product name of the product is "ZDEL".

なるから、これによつて衝撃波の伝達効果が増大
される。 Since the impact absorbers 1, 1 are spherical, a large number of gaps S are formed between the absorbers, and these gaps S perform an air action, that is, an air damper action when the exterior body 2 is deformed, so that when an impact is applied, A suitable elastic buffering effect can be obtained, so even if a strong impact force is applied, it can be transmitted to the impact absorber 1 while being attenuated by the air action. Since a large number of shock absorbers 1 are used,
They each have an independent buffering effect and also propagate the impact force applied to each other, so they have the effect of being able to respond well to complex impact forces, such as shock waves from multiple directions, and when the impact force is large, As the deformation of each absorber 1 increases, the degree of mutual adhesion also increases, thereby increasing the shock wave transmission effect.
従つて本発明衝撃体は、緩衝力の大きさに対応
して緩衝作用を増大させる事が出来ると云う効果
がある。 Therefore, the impact body of the present invention has the advantage that the shock absorbing effect can be increased in accordance with the magnitude of the shock absorbing force.
