Evacuation slide having toe end transverse support tube

摘要

An inflatable evacuation slide includes a feature for propelling disembarking passengers onto their feet at the toe end of the slide. In one embodiment, the slide comprises a fabric sliding surface stretched between two lateral side rail tubes. The lateral side rail tubes are supported by plurality of transverse tubes and transverse trusses such that the side rail tubes maintain the sliding surface in a taut condition suitable for use as a slide. The foot end of the tube includes a transverse tube having a reduced diameter and a lower surface that is suspended above the ground or other surface on which the foot end of the evacuation slide is resting. The suspended toe end transverse tube has a lower spring rate than a full-diameter transverse toe end tube. Therefore, the suspended toe end transverse tube provides the appropriate springiness for catapulting a sliding passenger onto his or her feet at the foot end of the slide notwithstanding the higher inflation pressure.
