Patent ID: 8596432

Claim:
A shock absorbing apparatus, comprising: a pressure-receiving plate portion to which shock is applied; a facing plate portion facing the pressure-receiving plate portion and being separated therefrom by an interval; and checkered ribs connecting the pressure-receiving plate portion with the facing plate portion and forming and demarcating a plurality of minor compartments between the pressure-receiving plate portion and the facing plate portion; the plurality of minor compartments comprising: filled minor compartments holding and containing a gelatinous filling consisting of a gelatinous body containing a liquid as a major component; vacant minor compartments containing air; and at least a first one of the vacant minor compartments adjoining a first one of the filled minor compartments; a second one of the vacant minor compartments adjoining the first one of the vacant minor compartments; a fragile section being formed in at least one rib of the ribs, the one rib demarcating the first one of the filled minor compartments and the at least first one of the vacant minor compartments; and another fragile section formed in another one rib of the ribs, the another one rib demarcating the first one of the vacant minor compartments and the adjoining second one of the vacant minor compartments, wherein the ribs buckle to absorb shock energy and the gelatinous filing is compressed to further absorb the shock energy when shock is applied in such a direction that brings the pressure-receiving plate portion and the facing plate portion closer to each other; and the shock energy is furthermore absorbed by circulation resistance to the gelatinous filling that flows from the first one of the filled minor compartments to the at least first one of the vacant minor compartments after the fragile section has fractured.
