An aircraft seat frame including a seat back portion, having a pair of side rails secured to a seat foundation portion so as to transfer a load thereto, the seat foundation portion coupled to a seat base portion that is substantially strong so as to resist yielding. The seat base portion includes a pair of base rails having mount segments extending downwardly therefrom for coupling to an underlying support surface, and at least one spar rail secured between the base rails. The base rails also include an upper edge, a lower edge, and an interior base segment, each having a flat, planar configuration, with the upper edge base segment disposed at a top edge of the interior base segment in perpendicular relation thereto and the lower edge base segment disposed at a bottom edge of the interior base segment in perpendicular relation thereto, so that the upper edge, lower edge, and interior base segments are disposed to maximize a resistance of the base rail to vertical bending across a plane of the upper and lower edge base segments, while minimizing an overall weight of the base rails. Further, the base rails and spar rail are structured to be coupled to one another to define a plurality of mount profiles each of which accommodates a particular mounting posture of the seat foundation portion and seat back portion for a particular mount location, without necessitating modification of a configuration of the seat foundation portion.

Aircraft passenger seat frame

An attenuated aircraft seat back assembly for use on an aircraft passenger seat of the type which includes a seat back frame with a front side and a rear side, the attenuated assembly comprising a mount assembly structured to be secured at the rear side of the seat back frame, preferably at an upper end thereof, and an impact absorbent, generally rigid material panel fixedly secured thereto. The mount assembly is structured to securely maintain the rigid material panel in a generally parallel orientation relative to the seat back frame, and spaced apart from the seat back frame by a predetermined distance. The rigid material panel, which is sized and configured to shield an upper region of the seat back frame, is substantially lightweight and includes a honeycomb interior core structured and disposed to substantially resist the force of a direct impact thereto, while still yielding sufficiently so that an object impacting the rigid material panel will have a Head Injury Criteria (HIC) value which is acceptable under current Federal Aviation Administration regulations. Preferably, an energy absorbent, resilient material panel is adhered to a front face of the rigid material panel, and together have a combined thickness of generally about two inches, while being spaced apart from the seat back frame in assembled form so as to minimize an overall thickness of the assembly.

Attenuated seat back assembly for an aircraft passenger seat

A recline safety lock assembly to be secured to an aircraft passenger seat of the type including a reclining seat back portion, a seat foundation and at least one recline cylinder structured to permit reclining of the seat back portion. The recline safety lock assembly includes at least one lock plate having an upper mount portion to be secured to a side rail of the seat back portion, and an engagement end having a downwardly depending lip formed therein. Additionally, the assembly includes at least one lock pin having a main shaft with a transverse notch formed therein. The lock pin is rotatably and axially mounted adjacent the engagement end of the lock plate and is rotatable between a disengaged orientation and an engaged orientation. In the engaged orientation the transverse notch is in a generally upwardly angled orientation such that the lock pin engages the downwardly depending lip of the lock plate and rear reclining of the seat back portion relative to the seat foundation portion is prevented. Conversely, the disengaged orientation includes the transverse notch disposed in a generally horizontal orientation so as to permit free passage of the downwardly depending lip of the lock plate therethrough and to permit normal reclining of the seat back portion relative to the seat foundation portion.

Recline safety lock assembly

An aircraft seat frame including a seat back portion, a seat foundation portion, and a seat base portion, the seat back portion having a pair of generally vertically disposed side rails composed of three interconnected segments, a leading and a trailing edge segments of which are perpendicularly disposed on opposing sides of an interior segment, thereby substantially minimizing an overall weight of the side rails and maximizing the side rails resistance to horizontal bending across a plane of the leading and trailing segments. Further, the seat frame includes a load transference member spanning the side rails so as to evenly distribute a load exerted on only a single of the side rails over both side rails and over the corresponding seat side rails to which the seat back side rails are connected. Further, the frame includes a seat base portion having a pair of seat side rails with support members pivotally secured at opposite ends thereof, the support members being fixedly secured to an underlying support surface.
