Abstract
An adjustable-curvature structure, e.g. for seat backs, comprises a pair of support belts which are flexible but substantially inextensible, and a pair of tension belts juxtaposed with the support belts. A grid of transverse bars can span the support belts and a tension device is provided between the two pairs of belts so that the support belts can be bowed when the other belts are placed under tension. The curvature character is controlled by spacers which interconnect the support and tension belts to limit the distance between them at various locations along their lengths.
