Abstract
A pair of crisscrossing straps and a pair of tension straps connect the two ends of a rigid U-shaped member to the two sides of the backrest of an aircraft crewmember's seat. The end portions of the U-shaped member have slip rings which are the support points for a pair of support straps which form loops encircling the crewmember's rib cage. The support straps can move through the slip rings thereby allowing the crewmember the ability to turn to either side while secured to the seat by the restraint system. In another embodiment of the invention, the crisscrossing straps are eliminated and a pair of wedge shaped support pads mounted on the front surface of the backrest of the seat are used instead of a U-shaped member. The tension straps and the crisscross straps are connected to inertial reels mounted at the sides of the backrest of the seat in order to provide restraint to each side of the support strap system.
