Abstract (en)
This invention discloses a type of underframe of sitting/sleeping furniture, comprising a supporting frame and a seat frame with backrest. This seat frame is arranged on this supporting frame in a movable manner via a quasi-parallel deflecting system. This quasi-parallel deflecting system consists of the supporting frame, the seat frame, and two rockers, so that the seat frame can move between two terminal positions: sitting position and sleeping position. With this underframe, when the seat frame moves between sitting position and sleeping position, rear pivot and front pivot of the quasi-parallel deflecting system are formed and arranged on the supporting frame, so that resultant gravity of the person at sleeping position is applied at a point behind the two pivots on the seat frame along the direction of the backrest. On the other hand, resultant gravity of the person at sitting position is applied at a point in front of the rear pivot on the seat frame. The structure of this invention can ensure motion characteristics of this underframe (preventing unintended movement).
