The invention concerns a support member that can be rolled up and is intended for awnings, tents, lightweight footbridges, etc. A large number of blocks 3 are arranged side by side and secured to an elongate band 1 which crosses them and is essentially non-extensible, preferably a steel band. The band 1 can therefore bend in only one direction. In the other direction the blocks 3 are pressed together which prevents continued bending. <IMAGE> |
