Abstract

In an illustrative embodiment, an aircraft seatback pocket spring provides a pre-loaded spring force for holding the pocket closed. The pocket spring may include a length of a wire extending between inner surfaces of frame members on either side of the seat and forming an upper edge of the pocket. Second lengths of wire may extend from ends of the first length of wire in a vertical direction to form side edges of the seatback pocket. Coils may be formed at each end of the second lengths of wire and may be mounted to receiving elements provided on inner surfaces of the frame members. Extension members extending from the coils may contact a contact point on the same or proximate frame members to maintain the pre-loaded spring force on the coils.

Dependent claims

An aircraft passenger seat including a seatback pocket, comprising:

a pocket spring configured to provide a pre-loaded spring force for holding the seatback pocket in a closed position against a rear surface of a seatback, the pocket spring comprising
a first length of a wire extending between inner surfaces of a pair of static base frame members disposed on either side of the aircraft passenger seat in a substantially horizontal direction, the first length of the wire forming an upper edge of the seatback pocket,
a pair of second lengths of wire extending from respective ends of the first length of wire in a substantially vertical direction, the pair of second lengths of wire forming side edges of the seatback pocket,
a pair of coils each formed at a respective end of the pair of the second lengths of wire, each of the coils mounted to a respective receiving element disposed on a respective inner surface of the pair of static base frame members such that an axis of the pair of coils is aligned perpendicularly to the inner surfaces of the pair of static base frame members and generally parallel to the seatback, wherein at least one of a number of turns of each of the pair of coils surrounding the outer surface of the receiving element and a diameter of each of the pair of coils is selected based on an amount of pre-loaded force exerted by the pocket spring, and wherein each of the pair of coils surrounds an outer surface of the respective receiving element, the respective receiving element having a substantially cylindrical shape, and
a pair of extension members extending from each of the pair of coils, each of the pair of extension members configured to contact a complementary contact point on inner surfaces of the static base frame members or additional static base frame members proximate to the static base frame members, the pair of extension members maintaining the pre-loaded spring force on the pair of coils;
and
a pocket panel configured to cover and enclose the pocket spring such that the pocket panel forms a pocket portion of the seatback pocket configured to hold one or more items.
