Abstract: A passenger seat includes a spreader frame structure and a seat back pivotally attached to the spreader frame structure. At least one cable can pass through apertures between the seat back and the spreader frame structure. The seat can rotate between an upright configuration wherein the seat back is in a deployed position, and a break over configuration wherein the seat back is in a stowed position. The length of the at least one cable between the aperture in the seat back and the aperture in the spreader frame structure is approximately the same in the upright configuration and in the break over configuration.

Abstract: Described are ergonomic passenger seats that may include monocoque or semi-monocoque seat backs, cellular suspension cushions, and tray tables with support arms that may be located within the interior volume of the monocoque or semi-monocoque seat backs when in their stowed positions. The passenger seats offer enhanced passenger comfort and space while providing a lightweight, simple to manufacture design. Monocoque and semi-monocoque seat backs may form integral parts of passenger seats to support additional loads without need for heavy, complex structures. The space within the monocoque or semi-monocoque seat back may then be used for storage or suspension cushions that offer improved comfort with a lighter seat frame. Monocoque and semi-monocoque seat backs may also facilitate the adoption of several other seating mechanisms, such as new seat mounts that allow for improved seat motion that allows for passenger recline with reduced impingement on other passengers' space.

Abstract: A separable multiple-piece frame assembly (100) for a passenger seat of a vehicle includes a first spreader portion (101) with an inner face, a second spreader portion (201) with an inner face, a plurality of attachments (11, 12, 13, 14, 15, 16) for releasably attaching the first spreader portion (101) and the second spreader portion (201), and an attached configuration. In the attached configuration, the inner face of the first spreader portion and the inner face of the second spreader portion are in contact with one another.

Abstract: Channel joints (1) can permit bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive.

Abstract: Described are seat backs (102) for aircraft passenger seats (100). Such a seat back (102) can include a unitary structural core (112) formed as a single piece that includes a body (138) and a flange (140). The body (138) and the flange (140) can each include carbon fiber composite material. The flange (140) can include portions extending from the rearward-facing side (132) of the body respectively along a left lateral side edge, a top (134) side edge, and a right lateral side edge of the unitary structural core (112). The flange (140) can be non-tubular.

Abstract: Described are channel joints (1) for bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive. The resulting joint is less likely to have voids, has additional bonding area compared to lap joints, and prevents the adhesive or bonding agent from experiencing tensile loads.
