Abstract: The invention is capable of maintaining the planar view curve profile of the elastic membranous member of the back-contacting surface while enabling the maintenance of a stable and comfortable seated posture. The side frame members (13C) of a backrest frame (13) are formed substantially as obtuse angles with the bend towards the front when viewed from the side. The upper frame member (13A) is formed, in planar view, as an arc that protrudes towards the back. An elastic membranous member (14) is stretched so that when viewed from the side, the intermediate position curves gently towards the front, substantially forming an obtuse angle. Paired left and right shape-maintaining members (17), each slanting outward and upward, connect the lower frame member (13B) near the left and right sides to the bends (13a) in the left and right side frame members. The lower parts of both the left and right sides of the elastic membranous member are supported by the shape-maintaining members.

Abstract: An aircraft passenger seat configured in accordance with an embodiment of the invention utilizes composite materials to achieve significant weight savings relative to conventional seat designs. The seat includes one or more lightweight composite support legs, a lightweight composite seat pan, and a lightweight composite seat back structure. The support legs are coupled to the seat pan, which is in turn coupled to the seat back structure. The support legs utilize composite frame elements that are formed as continuous compression molded composite extrusions. The seat pan includes composite fore and aft cross beams that are also formed as continuous compression molded composite extrusions. The aft cross beam includes a rear flange that serves as a flexible “hinge” for the seat back structure. The seat can leverage producible and relatively inexpensive composite manufacturing techniques such that the seat can be economically produced for use as an economy class seat.

Abstract: A vibration damper for a vehicle seat back is disclosed. The vibration damper includes an enclosure provided inside the upper end of a vehicle seat back. The enclosure includes a plurality of projections, preferably in the form of spaced apart, vertically extending pins, extending from one or more interior walls of the enclosure.
