Abstract

L'invention concerne un dispositif pliable qui peut comprendre une couche pliable et un dispositif de charnière qui est fixé entre un premier corps et un second corps du dispositif pliable. Le dispositif de charnière peut comprendre une pluralité de solives disposées en une pluralité de rangées. Une pluralité de ressorts à fil peuvent s'étendre à partir du premier corps, à travers la pluralité de solives, vers le second corps. Dans une configuration pliée du dispositif pliable, la pluralité de solives sont fixes sur la pluralité de ressorts à fil, chaque solive venant en butée contre une solive adjacente pour définir un contour correspondant à un rayon de courbure de la couche pliable. Dans une configuration dépliée, la pluralité de solives est mobile le long de la pluralité de ressorts à fil.
