Abstract
Abstract A headrest for airplane seats, and more particularly for helicopters which provide crash protection to the pilot by the use of a resilient pivotal coupling between a headrest supporting member and the headrest assembly itself. An integrally attached, rapidly movable visor is provided which is movable from a first position wherein it does not restrain the pilot''s head to a second position where it does restrain the pilot''s head, at the same time the headrest provides visibility and armored protection completely around the pilot''s head.

An improved removable armored headrest system for an armoved helicopter chair comprising; a. a chair having a seat portion and a back support portion; b. a support member movably attached to said back portion of said chair; said support member having a substantially elongated tubular shape and having a rectangular end section extending a substantial distance above said back support position of said chair; c. a neck member having first and second end portions, said first end portion formed into a hollow cylindrical member to completely enclose and extend a substantial distance along said rectangular end of said support member, said second end portion formed into a wye shaped member to extend in a forward direction from said back support portion; d. resilient material in intimate contact with external surfaces of said rectangular end section, said resilient material extending completely within said hollow cylindrical member for forming a resilient pivot coupling between said hollow cylindrical member and said rectangular end section; e. a headrest having first and second side portions attached to said second end wye shaped member; and, f. a transparent armored visor pivotably mounted to said first and second side portions of said headrest, said visor pivoting from an open position having no constraints upon a pilot''s helmet to a closed position having constraints applied to movement of a pilot''s head; whereby the resilient material permits the headrest to rotate angularly about the support member and allows absorbing of forward, sideway and backward blows during crashes.
