    Abstract: Polyimides displaying low color in thin films, atomic oxygen resistance, vacuum ultraviolet radiation resistance, solubility in organic solvents in the imide form, high glass transition (Tg) temperatures, and high thermal stability are provided. The poly(amide acid)s, copoly(amide acid)s, polyimides and copolyimides are prepared by the reaction of stoichiometric ratios of an aromatic dianhydride with diamines which contain phenylphosphine oxide groups in polar aprotic solvents. Controlled molecular weight oligomeric (amide acid)s and imides can be prepared by offsetting the stoichiometry according to the Carothers equation using excess diamine and endcapping with aromatic anhydrides The polyimide materials can be processed into various material forms such as thin films, fibers, foams, threads, adhesive film, coatings, dry powders, and fiber coated prepreg, and uses include thin film membranes on antennas, second-surface mirrors, thermal optical coatings, and multi-layer thermal insulation (MLI) blanket materials.

    Abstract: A pivoting headrest assembly including a bracket supported upon a seatback frame. A headrest support secures a bun and is pivotally secured to the bracket in a forward biased direction. A sector is pivotally secured to the bracket and to which is attached the headrest support. A release catch is pivotally supported at a further location of the bracket and is biased in a first upward direction so that the catch abuts a projecting pin associated with the sector in an upright design position established by the headrest support. A cable is secured to a support fixed to a side of the bracket and engages the catch at a location offset from its pivot axis relative to the bracket. Upon displacement of the cable, the catch is actuated out of engagement with the sector, resulting in the headrest support pivoting relative to the seatback.
