Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1-19, the zero gravity deformation seat frame of the utility model has two use states, namely a sitting state and a reclining chair state. The seat can be switched back and forth through the movement drive of the telescopic rod 5 in two postures of a sitting state and a reclining chair state, when the seat is in the sitting state, the telescopic rod 5 is in an extension state, the front push rod 3 and the rear push rod 4 are both erected between the seat frame 2 and the underframe 1, the seat frame 2 is horizontally placed, the foot plate frame 6 is retracted to be right below the seat frame 2, and the first foot seat rod hole one 611 is positioned below the second foot seat rod hole one 621. When the seat is in a reclining chair state, the telescopic rod 5 is in a shortened state, the front push rod 3 and the rear push rod 4 are in forward tilting and swinging states, the seat frame 2 is in a tilting and swinging state with the front end lifted upwards, the foot plate frame 6 extends forwards from the seat frame 2, and the first foot plate rod hole one 611 is positioned in front of the second foot plate rod hole one 621.

When the seat frame is in a sitting state, a user sits on the seat frame, and then the control device of the seat controls the telescopic rod 5 to shorten, and the rod hole II 52 is matched with the rear pushing hole III 43, so that the telescopic rod 5 contracts to drive the rear push rod 4 to swing forwards, thereby pushing the seat frame 2 and the front swing rod 3 forwards, and finally pushing the seat frame 2 forwards to a tilting state that the front end of the seat frame is lifted upwards.

The following will refer to the swing direction of the sectional view with reference to fig. 2. Considering only the movement of the triangle spiral plate 7 and the front push rod 3, the triangle spiral plate 7 mounted on the seat frame 2 is pushed forward together when the seat frame 2 is pushed forward, and the second auxiliary rod hole 77 tends to continuously reduce the distance from the first front push hole 31 and the second front push hole 32 because the third front push hole 33 is positioned between the first front push hole 31 and the second front push hole 32, and then the triangle spiral plate 7 and the spiral plate auxiliary rod 75 mounted on the front push rod 3 push and rotate the triangle spiral plate 7 in a clockwise direction by taking the spiral plate hole 71 as a rotation center, so that the foot plate push rod 65 and the backrest push rod 83 are pushed forward together. The foot plate push rod 65 pushes the fourth foot plate lever 64 forward, pushes the first foot plate lever 61, the second foot plate lever 62, the third foot plate lever 63 and the fourth foot plate lever 64 forward together to a position in which the first foot plate lever hole 611 is located in front of the second foot plate lever hole 621, so that the foot plate frame 6 extends in a nearly flat position, and the backrest push rod 83 pushes the backrest swing plate 9 forward to swing counterclockwise about the swing plate hole 91 as a rotation center, thereby pulling the backrest frame 8 downward by the backrest auxiliary push rod 86, and the backrest frame 8 swings counterclockwise about the backrest hole 81 as a rotation center, so that the backrest pad mounted on the backrest frame 8 swings downward to an inclined position. Finally, the seat cushion of the seat frame swings at a larger obtuse angle with the seat cushion in an inclined swinging state with the front end lifted upwards, and the leg rest plate is lifted to a position higher than the seat cushion.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and improvements could be made by those skilled in the art without departing from the inventive concept, which falls within the scope of the present utility model.
