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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 248 words
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.
