Escape slide
First Claim
1. An aircraft life raft assembly for use from an elevated egress opening of an aircraft comprising a longitudinally extending inflatable escape slide, said slide having a longitudinally extending center line, said slide having a head end and a toe end, said head end being located adjacent said egress opening, said toe end upon deployment of said slide being located adjacent a horizontally extending ground plane at an elevation below that of said egress opening, a flexible material secured to said escape slide having an upper surface extending in said longitudinal direction defining a slide surface when said escape slide is inflated, pressurizing means operative upon actuation to inflate said escape slide, said escape slide having an intermediate portion located along the length of said escape slide between said head end and said toe end, and said intermediate portion of said escape slide having a curvilinear section in plan view.

Abstract
An aircraft life raft assembly for use as a deployable escape slide from an egress opening of an aircraft. The escape slide is a longitudinally extending structure with a center line that extends from the head end of the slide, adjacent the egress opening, to a toe end that is located adjacent the horizontally extending ground plane. Pressurizing means is operative to inflate the escape slide, which escape slide has panels or panel members of flexible material with an upper sliding surface that extends in the longitudinal direction. The escape slide has a portion of its length that is curvilinear in plan view, which curvilinear portion maybe close to the egress opening of the aircraft or anywhere along the length of the escape slide.
