Abstract: A headrest frame for a seat is disclosed. In various embodiments, the headrest frame includes a main body portion having a stowed length; a top portion configured to assume a stowed position and a deployed position with respect to the main body portion, the deployed position defining a deployed length greater than the stowed length; and a deployment mechanism configured to urge the top portion into the deployed position from the stowed position.

Abstract: An inertial lock assembly is disclosed. In various embodiments, the inertial lock assembly includes a tracking rod oriented with respect to a longitudinal axis, a housing slidably disposed about the tracking rod, the housing including an inner surface having a first portion extending from an apex to a first end spaced longitudinally from the apex, a first sliding member slidably disposed about the tracking rod and within the housing proximate the first portion of the inner surface and a first binding member slidably disposed about the tracking rod and within the housing, the first binding member positioned between the apex and the first sliding member.

Abstract: The invention provides cryogenic structures, e.g. vessels or tanks joined by longerons, which are made of durable plastic composite materials rather than of metal, which vessels can contain cryogenic materials including fuel, without need of a liner or other weighty layers of the prior art. The structures are made of, e.g. a fiber network impregnated with a matrix of thermoset plastics, thermoplastics or a combination thereof. Thus the invention includes a cryogenic vessel of, e.g. 3 tank lobes, made of a composite of plastic reinforced with fibers, which lobes are joined together and supported by woven, cruciform shaped longerons which are also impregnated with plastic, to define a composite support member.
