Abstract: An evacuation system may comprise a packboard, an evacuation slide configured to deploy from the packboard, and a lane dividing apparatus attached to the evacuation slide, the lane dividing apparatus comprising a strap having flexible material. The lane dividing apparatus may be a dual wall lane divider. The lane dividing apparatus may be a single lane dividing apparatus. The lane dividing apparatus may comprise a first patch disposed at a proximal end of the evacuation slide and a second patch disposed at a second end distal to the proximal end. The lane dividing apparatus may extend from the proximal end to the second end. The lane dividing apparatus may be taut upon deployment of the evacuation slide.

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.
