Shock-absorbing structure for e.g. blasting blanket, has gas accumulation cavities closed and connected to outlet and inlet to evacuate gas contained in chambers outside structure, in case of impact on structure, and to fill containers

摘要

The structure (I) has a porous body (1) in which spherical shaped shock-absorbing chambers (2) constituting gas accumulation cavities are arranged. The cavities are closed and connected by gas passage paths to an outlet and an inlet to evacuate gas contained in the chambers outside the structure, in case of impact on the structure, and to newly fill containers. The porous body is made of a memory shape material or viscoelastic material e.g. polyurethane. The porous body has a thickness higher than a height of the chambers.
