The structure comprises a certain number of bars or the like 10 to 17 which are essentially rigid and connected in an articulated manner, with springs 22, 23 interacting with at least one part of the articulation points 6 to 9 connecting the bars or the like, so as to push the bars back along the folding and deployment direction in the folding or deployment sense. Several elements 1 are provided connected to one another and each comprising two sets of four bars 10 to 13, 14 to 17 and six articulation points 4 to 9 arranged in three mutually interacting pairs, at one end, at the other end, and in the middle, the two points 4, 5; 6, 7; 8, 9 of each pair being able to move transversely to the direction of deployment, two bars 10, 13; 14, 17 of each set remaining on just one side of the median deployment line and the two other bars 11, 12; 15, 16 passing through this line and crossing one another. <IMAGE>
