A system for the evacuation of individuals trapped in multiple storey buildings by gliding down a rescue sleeve. The sleeve (12) is composed of sections (20), each section being made of a sheet material strengthened by a circumferential rigid support member (22), the sections are connected to each other to form a continuous envelope. At least a pair of cables (26; 27) are provided, thread along the sleeve, one (26) at the bottom and one (27) at the top generatrix thereof. A pair of winch systems (52; 54) are provided for winding the cables (26; 27) into a dedicated location (50) at the building storey from which rescue is requested, so that the sleeve (12) becomes folded into a compact package. Coil Springs (60; 62) are used for selectively ejecting and unfolding the sleeve down to ground level where it becomes tied to stationary objects (16; 17).
L'invention porte sur un système d'évacuation de personnes coincées dans un bâtiment à plusieurs étages au moyen de toboggans (12) composés de sections (20) faites d'un matériau en feuille raidi par un élément support rigide circonférenciel (22), et reliées les unes aux autres de manière à former une enveloppe continue. Il est prévu deux câbles (26; 27) au moins, l'un (26) courant le long de la génératrice supérieure, et l'autre (27), le long de la génératrice inférieure, ainsi qu'une paire de treuils (52; 54) d'enroulement des câbles (26; 27) placés en des points précis (50) de l'étage où l'évacuation est requise, et où le toboggan (12), à l'état plié, forme un paquet compact. Des ressorts hélicoïdaux (60, 62) assurent l'éjection et le déploiement du toboggan jusqu'au niveau du sol, où il est attaché à des objets fixes (16; 17).
