Abstract
A windblast arm protector assembly for use by an occupant of an open-type ejection seat of an aircraft. The assembly includes, for each arm of the seat occupant, a full length fabric sleeve member which is independent of any garment body, which is a part of the seat's restraint system (rather than an item of personal protective equipment), and which is shaped and dimensioned from the shoulder area to its wrist area in the form of a flexed (i.e., bent) arm. During ejection of the seat and occupant together, the sleeve member is pulled forwardly and adjacent to the occupant's sides by associated co-acting components of the assembly, such that the arm is not extended into the windblast and is protected from it. Unlike the prior art, this arm protector assembly restrains the wrist area of the seat occupant's arm near the seat ejection handle, while the arm is restrained over its entire length. As a result, the windblast load is uniformly applied, and the restrained arm is protected from injury.
