Abstract
A structure comprises at least two unfurling panels and a spacing and knock prevention device intended to prevent the panels from knocking together when they are furled against one another. The knock prevention device comprises a holder fixed to the first panel, a cap forming a buffer against which the second panel bears in a bearing direction, and a damper disposed in a space formed between the holder and the cap. The cap and the holder form two elements. A first of the two elements comprises at least one lug. The second of the two elements comprises at least one housing intended to receive the lug. The cap is configured such that the lug passes into the housing by elastic deformation of the cap.
