Abstract

An evacuation system may comprise a packboard, an evacuation slide configured to deploy from the packboard, and a canopy support apparatus is disclosed. The canopy support apparatus may comprise a valve extending from a proximal end of a canopy support tube toward a distal end of the canopy support tube and into an internal cavity of the canopy support tube. The valve may be configured to open a channel during inflation. The valve may be configured to seal the channel via internal pressure in the internal cavity acting on a sealing component of the valve when the canopy support tube is in an inflated state.

First claim

What is claimed is:

1. An evacuation system, comprising:
a packboard;
an evacuation slide configured to deploy from the packboard; and
a canopy support apparatus comprising a canopy support tube and a valve disposed within the canopy support tube, the canopy support apparatus comprising an inflating component coupled to the valve at an inlet to the valve, the inflating component comprising a first tab and a second tab, the first tab and the second tab each comprising a fastening component disposed on an inner surface, the canopy support tube comprising a proximal end, a distal end, and an internal cavity, the valve extending from the proximal end toward the distal end and into the internal cavity, the valve configured to seal the internal cavity when the canopy support tube is in an inflated state.

2. The evacuation system of claim 1 , wherein the evacuation slide further comprises a center tube, the canopy support apparatus configured to attach to the center tube.

3. The evacuation system of claim 1 , further comprising a plurality of the canopy support apparatus.

4. The evacuation system of claim 3 , further comprising a plurality of canopy supports coupled to a first rail of the evacuation slide and a second rail of the evacuation slide.

5. The evacuation system of claim 4 , wherein the plurality of canopy supports is integrally formed and in fluid communication with the first rail and the second rail.

6. The evacuation system of claim 1 , wherein the canopy support apparatus further comprises an inflating component coupled to the valve at an inlet to the valve, the inflating component comprising a first tab.

7. The evacuation system of claim 6 , wherein the first tab comprises a fastening feature.

8. The evacuation system of claim 6 , wherein the inflating component further comprises a second tab disposed opposite the first tab.

9. The evacuation system of claim 6 , wherein the channel of the valve is configured to expand when air is blown through the inlet.

10. A method of using a canopy support apparatus, comprising:
pulling a first tab and a second tab of an inflation component of the canopy support apparatus in opposite directions;
expanding a channel in a valve, the valve disposed in an internal cavity of a canopy support tube, the expanding occurring by blowing air into an inlet of the valve of the canopy support apparatus;
sealing the channel in the valve by an internal pressure in the internal cavity of the canopy support tube acting on a sealing component of the valve;
attaching a first surface of the first tab and a second surface of the second tab to an evacuation slide; and
attaching a distal end of the canopy support apparatus to a canopy.
