First claim
Opening claim text (preview).
What is claimed is: 1. A parachute assembly, comprising: a canopy; a plurality of suspension lines coupled to the canopy; a riser located at an end of the plurality of suspension lines opposite the canopy; and a life preserver head restraint configured to inflate in response to an increase in tension in the riser. 2. The parachute assembly of claim 1 , further comprising a charge tank fluidly coupled to the life preserver head restraint. 3. The parachute assembly of claim 2 , further comprising a lanyard coupled between the charge tank and the riser. 4. The parachute assembly of claim 3 , wherein the increase in tension in the riser is configured to translate the lanyard. 5. The parachute assembly of claim 4 , wherein the lanyard is coupled to a valve of the charge tank, and wherein translation of the lanyard is configured to actuate the valve to an open position. 6.
