| 摘要 |
The present invention relates to a load distribution composite. This comprises a plurality of lower wedges with their broader bases disposed in a slideable spaced-apart relation along a resting plane. Superposed in reverse slideable relation between adjacent pairs of the lower wedges are a plurality of upper wedges. A guide rod extends laterally between a pair of fixed supports at opposite ends of the composite of upper and lower wedges which are aligned along the base in contiguous relation. The upper wedges are internally slotted to permit them restricted vertical and horizontal movement in slideable relation against the surfaces of the lower wedges, in response to the selective application of load pressure along the surfaces of the upper wedges. The principles of the invention has wide application to supporting or buffering surfaces. Examples include chairs, beds and vehicle interiors.
