A support structure comprises a plurality of support members (1) providing opposed first and second support surfaces (4 and 5) extending between the ends thereof. The support members (1) are arranged generally end-to-end in a chain with a preferably cylindrical bearing member (2) between each adjacent pair of support members. Each support member (1) provides at opposed ends thereof a pair of contact surfaces (3) spaced apart from each other and engaging the surface of the bearing member, whereby the support members may be positioned on the bearing members with the support surfaces of one support member at a selected angle to the support surfaces of the next adjacent support member such that the chain describes a desired curved configuration. The structure further comprises linking means (7, 8, 9) linking the first support surface of each of the support members to the first support surface of the or each adjacent support member in the chain so as to maintain the desired curved configuration. |
