Aircraft passenger seat frame

An aircraft seat frame comprising:

• (a) a seat back portion, said seat back portion including:
• a pair of spaced side rails structured to generally define a width of said seat back,
• a load transference member spanning said side rails at generally a lower end of said side rails and secured thereto in a generally flush, perpendicular relation,
• said load transference member having a generally tubular configuration and being structured and disposed to transfer a portion of a load exerted on one of said side rails to a second of said side rails, and
• said load transference member having a diameter greater than a width of an upper portion of said side rails, so as to maximize a load transference thereof, while including a minimal wall thickness so as to minimize a weight of said load transference member, and
• (b) a seat foundation portion, said seat back portion being secured to said seat foundation portion such that the load exerted on said side rails of said seat back portion is translated into said seat foundation portion.

An aircraft seat frame comprising:

• (a) a seat back portion, said seat back portion including at least two spaced side rails,
• a load transference member spanning said side rails at generally a tower end of said rails and secured thereto in a generally flush, perpendicular relation,
• said low transference member having a generally tubular configuration and being structured and disposed to transfer a portion of a load exerted on one of said side rails to a second of said side rails, and
• said load transference member having a diameter greater than a width of an upper portion of said side rails, so as to maximize a load transference thereof, while including a minimal wall thickness so as to minimize a weight of said load transference member, and
• (b) a seat foundation portion, said seat foundation portion being secured to said seat back portion such that a load exerted on said side rails of said seat back portion is translated into said seat foundation portion,
• (c) a seat base portion, said seat foundation portion being supportably disposed on said seat base portion which is structured and disposed to be secured to an underlying support surface,
• (d) said seat base portion comprising:
• a pair of spaced base rails,
• each of said base rails including an upper edge base segment, a lower edge base segment, and an interior base segment, each of said segments having a generally flat, planer configuration,
• said upper edge base segment being disposed at a top edge of said interior base segment in substantially perpendicular relation thereto,
• said lower edge base segment being disposed at a bottom edge of said interior base segment in substantially perpendicular relation thereto,
• said upper edge, lower edge, and interior base segments being disposed relative to one another so as to substantially maximize a resistance of said base rails to vertical bending across a plane of said upper edge and lower edge base segments, while minimizing an overall weight of said base rails,
• each of said base rails further including at least two mount segments extending downwardly therefrom towards the underlying support surface,
• said mount segments including a retention segment structured and disposed to receive a support member therein, and
• said support member being rigidly, secured directly to the underlying support surface and being secured to said mount segment at said retention segment so as to pivot relative thereto upon a buckling of the underlying support surface.
