Abstract
A curved tracking platform that can be employed on a dynamic seat or divan such as those used in a business jet aircraft so that the seat can be comfortably used as a seat or in an extended bed position. When in the unextended seat position, the tracking platform allows the horizontal portion of the seat to support an occupant pitched back toward the vertical seat cushion at or about an angle of 6° to the horizontal. However, when the tracking platform is extended so that the seat can be used as a bed, the tracking platform travels along a curved frame rail profile which allows the platform to lay flat or substantially flat, thus allowing the vertical cushion to be placed next to the horizontal seat cushion so that they lie substantially flat to provide optimized comfort.
