  • Evacuation slide having trapezoidal outline
    Patent number: 6799741
    Abstract: An inflatable evacuation slide for emergency evacuation of an aircraft comprises a pair of main support tubes supporting a flexible sliding surface. The main support tubes taper from a widest point near the exit opening of the aircraft to a narrowest point at the foot end of the slide. This arrangement of main support tubes, together with the toe end transverse tube and the head end transverse tube, form a quasi-trapezoidal truss structure, which is inherently more stable than the rectangular slides of the prior art.
