Abstract: A support arrangement for an inflatable evacuation system may comprise an inflatable member configured to be elongated and stiffened in a longitudinal direction in response to being in an inflated condition, a protrusion extending orthogonal to a surface of the inflatable member, a tensile member attached at at least two locations to the inflatable member on opposing sides of the protrusion and being slidably engagable over the protrusion so as to maintain about equal tension in the tensile member on opposing sides of the protrusion, and a sleeve attached to the protrusion configured to maintain the tensile member laterally relative to the protrusion even as the tensile member is able to slide longitudinally.

Abstract: A life preserver head restraint may be configured to inflate in response to deployment of a parachute assembly. The life preserver head restraint may comprise an inflatable volume and a charge tank fluidly coupled to the inflatable volume. In an inflated state, the life preserver head restraint may restrict head movement during line stretch of the parachute assembly.

Abstract: A method for deploying an inflatable slide includes increasing pressure within the inflatable slide, increasing a load in a force releasing member and a dampener, both of which are attached to the inflatable slide, in response to the increasing pressure within the evacuation slide, the load being increased at a slower rate than would occur if the dampener were not present, separating the force releasing member, and inflating the inflatable slide.
