Definitions

  • the following invention relates to occupant recovery from an armoured land vehicle, and to a system for occupant recovery.
  • a method of removing an occupant to be extracted from an armoured land vehicle comprising the steps of deploying a flexible panel stretcher, locating the occupant in the flexible panel stretcher, retaining the occupant within said flexible panel stretcher, manoeuvring the occupant via a labyrinthine path within said armoured land vehicle, to avoid one or more protruding features, removing the occupant from an access point of the armoured land vehicle.
  • the access point may be an egress point.
  • the flexible panel stretcher substantially encapsulates the occupant.
  • Occupant recovery from a commercial vehicle may be greatly facilitated by the use of hydraulic cutting devices to remove pillars, roof panels, doors and seats.

  • Armoured land vehicles often have limited access portals and doors, as the armoured vehicle is required to withstand severe forces, and so access may be restricted to one major access portal. Further, armoured land vehicles are often cramped and comprise at least one, typically a plurality of protruding features, such as for example, hardware and kit to carry out complex missions. Therefore entering and exiting the vehicle typically comprises manoeuvring via a labyrinthine or tortuous path to avoid the at least one, typically a plurality of protruding features, such as, for example over seats, storage boxes, equipment, further occupants.

  • the occupant comprises at least one pulley fixing point attached to clothing or body armour, removable harness or lanyard, and a pulley removably attached thereto, the pulley comprising a line, such that pulling the line, the occupant is pulled onto a deployed flexible panel stretcher.
  • the flexible panel stretcher may comprise at least one restraint to retain the occupant within the flexible panel stretcher.
  • the restraint may be webbing, the webbing may be tightened and locked in place with any common fixing.
  • a pulley system may be attached thereto, to avoid further pulling forces being applied directly to the occupant.
  • the occupant's seat may be laid flat or the back of the seat may be removed, prior to extraction.
  • the flexible panel stretcher comprises at least one pulley fixing point and a pulley removably attached thereto, the pulley comprising a line, comprising the steps of retracting the line, so as to cause the flexible panel stretcher to manoeuvre the occupant via the labyrinthine path within said armoured land vehicle, to avoid the one or more protruding features.
