ABSTRACT:
An inflatable, generally horizontal, elevated platform fastened to a supporting structure is connected to an inflatable escape slide extending downwardly at an inclination from the platform to a lower surface. An elongated tension strap is connected at one end to the platform adjacent the supporting structure and at the other end to the slide at a position around midway down the slide to reinforce the platform and maintain the horizontal position of the platform under the weight of persons using the platform and slide.
The slide may have a laterally extending inflatable member on the underside with longitudinally extending slide reinforcing tension members cooperative with the laterally extending inflatable member to provide a truss-like structure. The tension strap for reinforcing the platform may be connected to the slide at a position at the laterally extending inflatable member at one end and be connected to the platform at a position adjacent the supporting structure at the other end. The platform also may have an edge connected to the slide which is not parallel to the edge adjacent the supporting structure in which case the tension member is located on the side of the platform where the edges are the greatest distance apart.
