  • Patent number: 9162735
    Abstract: An inflatable evacuation slide includes a base, one or more top tubes, a first lateral side, including a series of alternately upright and inverted generally triangular inflatable frames, each frame being coupled to neighboring frames in the series, a first common side of the base and at least one of said top tubes, and a second lateral side including a series of alternately upright and inverted generally triangular inflatable frames, each frame being coupled to neighboring frames in the series, a second common side of the base and at least one of said top tubes. The first common side of the base is opposite the second common side of the base so that the slide is generally triangular in cross-section, and the angles of the triangular frames combine to form an upwardly directed arcuate bend in the uninflated slide which straightens under the weight of the slide when inflated and deployed.

  • Patent number: 8376082
    Abstract: An inflatable evacuation slide, substantially triangular in cross-section, includes a base and lateral sides. The sides are formed from interlocking components, so that the slide is straight, when deployed. The inflatable evacuation slide may be used, for example, as a marine evacuation slide.
