Abstract

An escape slide for evacuating personnel from an aircraft or other elevated place where there is the possibility of damage to the slide from fire or abrasion during the deployment and evacuation process. A protective shield of flexible material having a metalized coating for reflecting heat is positioned over the underside of the inflated slide to protect the slide. The protective shield may be connected to the sides of the slide and be spaced from the bottom of the slide to provide an insulating air space. The protective shield may also be movable to a position over the slide when used as a life raft and serve as a canopy to protect passengers on the slide raft from the weather and sea.

Claims

1. An escape slide adapted to be inflated and extend from an upper end at an elevated position to a lower end at a lower surface comprising a slide portion including an upper surface on which persons are transported, side portions at each edge of said side portions, and a protective shield of flexible sheet material covering said bottom portion and at least a part of said side portions, wherein said protective shield is divided into at least two longitudinally extending sections having center edges releasably fastened together so that said sections may be detached and positioned over said upper surface as a canopy to protect persons using said escape slide as a life raft.

2. An escape slide in accordance with claim 1 wherein said escape slide has inflatable canopy supports positioned at said side portions for supporting said shield as a canopy in a sheltering location above said upper surface.

3. An escape slide in accordance with claim 1 wherein said two sections have attachment means for connecting said center edges after said sections are positioned over said upper surface of said escape slide.
