CA 2125642

A composite support frame structure for the construction of a seat. The support structure comprises a rigid continuous rod-like frame formed in a closed loop and having opposed diverging rod-like side members which lie in a common plane and opposed rod-like end members formed integral with the side members. At least one of the end members is arced outwardly. A belt of substantially non-extensible material forms a slightly truncated sleeve, narrower than the frame, to apply a compression force between the side members and to flex the arced end member. The sleeve is retained in tension about the opposed diverging rod-like side members by the restoring spring force between the side members exerted by the arced end member.
