An extendible, coilable member (2) is reversibly configurable between a coiled form and an extended form (2a). At least one surface of the member (2), typically an inner surface, is provided with resilient protrusions (2b). Upon extension of the member (2) to the extended form, the protrusions (2b) adopt a first state in which they protrude from the surface of the member (2). Upon rolling of the member (2) to the coiled form, the protrusions (2b) flex so as to lie between the turns of the coiled member (2).
L'invention porte sur un élément (2) enroulable, extensible pouvant passer d'une forme enroulée à une forme déployée (2a). Au moins une surface de l'élément (2), généralement une surface interne, est pourvue de parties saillantes (2b) résilientes. Lors de l'extension de l'élément (2) dans sa forme déployée, les parties saillantes (2b) adoptent le premier état dans lequel elles font saillie de la surface de l'élément (2). Lors de l'enroulement de l'élément (2), les parties saillantes (2b) fléchissent de façon à reposer entre les spirales de l'élément (2) enroulé.
