摘要

The support member (1), being intended for use -- for instance -- as a lumbar support member in the backrests of automobile vehicle seats, has a sand-glass or butterfly-like overall configuration with two side bodies (2) interconnected at a central location by a flexible intermediate body (3) adapted to allow relative orientation of said side bodies (2) both in the pattern of an ideal parliament-hinge configuration and a general torsional movement of said member (1).
