Abstract

A shock-load G-force minimizing seat structure which responds principally in non-springy compression, rather than in spring-loading bending, to vertically directed shock loads. The seat structure features an anti-springy frame structure which supports a thin and very lightweight seat cushion support spanner web formed preferably of a non-stretchy material, such as a material made out of elongate carbon-fibre strands.
