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.

The invention provides an in-flight emergency evacuation system in an aircraft which has a seating area comprising of plurality of rows of passenger seats which are positioned on plurality of rails. The passenger seats are slidably movable on the rails. The system further discloses at least one emergency room which is configured to accommodate the passenger seats inside it during an emergency condition for safely ejecting the passengers outside of the emergency rooms. During an emergency condition, the crew members of the aircraft can hit the evacuation button which automatically starts the evacuation process. Once the evacuation button is pressed, the slidably movable motorized passenger seats which are positioned on the rails starts moving in a sequential manner into the emergency room which is capable of accommodating one row of passenger seats at a time and ejecting it outside the aircraft.
