| 摘要 |
An elongated tubular structure, of non-stretchable material - preferably comprising impermeable-to-gas thin metal having: flat, wider, sealed ends; and intermediate, elongated links, each of which has a hollow portion, inflated with gas at a pressure well above that of the atmosphere, and a wider, bonded, flattened-tube band at each link end. Each flat, tubular-structure end comprises a welded, vulcanized or otherwise bonded, sealed joint between two flat sides of the structure and an outer-end means for attachment of this end to a similar portion at the other end and/or to adjoining structure (an end flange, optionally having bolt or rivet holes). Adjacent inflated links are preferably joined by a flatter, wider portion that preferably allows passage of gas between links and inflation of all the links from a single gas inlet, permanently sealed after inflation. The disclosure also comprises a strongly rigid or very stiffly resilient vehicular body (strongly protecting a load in a crash) and stiffly resilient shock-taking means, yieldable without fracture under major shock, comprising tubular structure of the above type.
