Embodiment Construction
[0009] Referring to Figure 1, there is a fixed movable shaft 1 on the backrest side, a reclining back turning shaft 3, a small tooth and a spring gear on the fixed movable shaft 1, and an armrest rotating shaft 2 between the shaft and the armrest. The movable shaft 4 moves up and down the seat cushion, there is a pulling head 5 under the seat cushion, and there is a handbrake 7 for manipulating the moving shaft 6 below. Follow-up moving axis 8.
[0010] The fixed movable shaft 1 has four gears, and the backrest can be straight or bent, with four different angles. When the backrest is to be bent, move it directly forward with your hands; when it is to be straight, move it forward first, and then pull the lead 5 to straighten it.
[0011] Manipulate the armrest rotation axis 2, the armrest can be raised horizontally or upward, manipulate the handbrake 7, the moving axis 6 moves forward or backward, the moving axis 8 moves backward or forward, the movable axis 4 rotates forward ...

A sofa that can be sat, lay down or lying relates to a sofa, in particular to a sofa for the sitting, lying down and lying of the people in travelling. The backrest side has a fixed loose axle and a backrest flip axis, and a handrail axis is arranged between the backrest side and the handrails. The joint of the backrest and a cushion has a movable axis for the upper and lower movement of the backrest and the cushion. A pulling strip head connected to a spring crosspiece of the fixed loose axle is arranged beneath the cushion. Under the cushion, a shifting axle for the manipulation of a shifting axle and a handbrake and following along the movement of the shifting axle is arranged. When the hand brake is manipulated, the shifting axle moves forward or backward, and the movable axis rotates forward or backward. The backrest and the cushion are changed to the lying down positions from the sitting positions, and at the end to the lying positions. The fixed loose axle has four positions and the backrest that can be straight or bended has four different angles. When the bending is required, the hands are used directly for the forward moving. When the straight position is required, the strip head is pulled after the first forward moving of the sofa so that the sofa can be straight. The invention has a scientific and rational structure which is easy to use and space-saving. Therefore, those who travel can be at the postures of sitting, lying down and lying without the feel of fatigue.
