Specifically, the fore-and-aft swinging support 3 is made of a metal hollow or solid pipe, and of course, the fore-and-aft swinging support 3 may also be made of a plastic material.

The lower end of the front and back swing support 3 is fixedly connected with a hinge shaft, a torsional spring is sleeved on the hinge shaft, the hinge shaft is rotatably connected with the seat cushion 2, two ends of the torsional spring respectively abut against the seat cushion 2, and the front and back swing support 3 swings in the front and back direction of the seat by using the structure.

Of course, other solutions are also possible: as shown in fig. 6, a lower protrusion 30 is provided at the lower end of the front and rear swing support 3, an arc convex surface 31 is provided on the lower protrusion 30, a conical insertion blind hole 20 into which the lower protrusion 30 is inserted is provided at the rear side of the seat cushion 2, an arc concave surface 21 matching with the arc convex surface 31 is provided at the bottom of the conical insertion blind hole 20, a rotating shaft 32 is transversely provided on the lower protrusion 30, rotating shaft holes 22 into which both ends of the rotating shaft are inserted one by one are provided on the hole wall of the conical insertion blind hole 20, and the lower protrusion 30 swings around the shaft axis of the rotating shaft in the front and rear direction of the seat relative to the conical insertion blind hole 20. An elastic part 33 is arranged between the rear side hole wall of the conical insertion blind hole 20 and the rear vertical surface of the lower convex part 30, the elastic part 33 is a pressure spring and is at least one, a first blind hole is arranged on the rear side hole wall of the conical insertion blind hole 20, a second blind hole is arranged on the rear vertical surface of the lower convex part 30, one end of the elastic part 33 is fixed on the first blind hole, the other end of the elastic part 33 is fixed on the second blind hole, the elastic part 33 is distributed in an inclined manner from top to bottom, and the upper end of the elastic part 33 is close to one end of the lower convex part 30.

The front side hole wall of the tapered insertion blind hole 20 is a vertical hole wall.

Of course, the lower end of the back and forth swinging support 3 is hinged to the metal seat cushion seat of the seat cushion 2, and the hinge joint can adopt the hinge structure of the conventional swivel chair and is directly commercially available.

As shown in fig. 1 to 5, a backrest 4 is mounted on the front and rear swinging support 3, two supporting cantilever parts 5 are symmetrically arranged on the backrest 4, one end of the supporting cantilever part 5 far from the backrest 4 is free, and a headrest 6 foldable on the backrest 4 is hinged at the upper end of the front and rear swinging support 3.

Will support on cantilever part 5 snap-on to back 4, back 4 then can drive support cantilever part 5 backward passively this moment and incline backward, when lying prone and attach the state, the interval between cushion 2 and the support cantilever part 5 is used for the entering of human shank.

The articulated of headrest 6 makes when attaching the state on lying prone, can be used for the support of human head to improve rest travelling comfort.

The rotation angle of the headrest 6 relative to the fore-and-aft swinging support 3 is 180-270 deg., wherein when the headrest 6 stands on the top of the fore-and-aft swinging support 3 in a vertically distributed manner (unfolded state), it can rotate forward and downward 180 deg. and the backrest 4 fits against a surface of the human body, i.e., the headrest 6 is folded to fit against a surface of the backrest 4 that is close to the human body.

The remaining 90 ° area is used for rearward rotation angle adjustment in the prone attachment state so that the chin can be completely placed on the headrest 6.

As shown in fig. 1-5, the headrest 6 and the back-and-forth swinging support 3 are connected by a hinged shaft, a compass is sleeved on the hinged shaft, a plurality of transverse holes are arranged on the circumference of the compass, and a transverse bolt inserted in any transverse hole is arranged on the headrest 6 in a penetrating way.

When the angle is adjusted, the transverse bolt is separated from the transverse hole, after the transverse bolt is rotated in place, the transverse bolt is inserted into the corresponding transverse hole, a spring is sleeved on the transverse bolt and prevents the transverse bolt from being separated from the transverse hole, for example, the inner end of the spring acts on a convex shoulder of the transverse bolt, the outer end of the transverse bolt extends out of the headrest 6, and the other end of the spring acts on a step surface of a bolt hole of the headrest 6.

A first concave-convex portion is provided on a surface of the backrest 4 close to the human body, and a second concave-convex portion is provided on the headrest 6, the first concave-convex portion and the second concave-convex portion being fitted to each other when the headrest 6 is folded to fit against a surface of the backrest 4 close to the human body. So that the headrest 6 is housed while the second concavo-convex portion at this time is used for support of the head when the headrest 6 is not in the folded normal standing state. For example, the first concave-convex portion of the present embodiment includes a back convex pad 40 provided on a central region of a surface of the back 4 close to the human body, and the second concave-convex portion includes a through hole 60 provided on the headrest 6, and the back convex pad 40 is inserted into the through hole 60 when the headrest 6 is folded to conform to a surface of the back 4 close to the human body.

As shown in fig. 1 to 5, the thickness of the headrest 6 is larger than that of the back rest convex pad 40, and when the headrest 6 is folded on the back rest close to a surface of a human body, a concave area is formed on the front surface of the headrest 6 and the front surface of the back rest convex pad 40 in this state, so that the center position of the back of the human body is kept free to prevent the back of the human body from being sweaty when the back of the human body is completely attached to the user.

The back convex pad 40 is circumferentially spaced from the through hole 60, and the width of the back convex pad 40 in the vertical direction is longer than that of the back in the vertical direction, so that the gap is penetrated by the outside.

Specifically, when the headrest 6 is rotated by an angle smaller than 90 ° to the rear side of the forward/rearward rocking support 3, the lower hole wall of the through hole 60 is the chin rest surface 61.

Next, lateral supports 62 attached to both sides of the head of the human body are provided on both sides of the headrest 6, respectively. The lateral support 62 may provide lateral support to the head of a person to improve comfort.

In addition, the free end of the supporting cantilever part 5 of the present embodiment is extended to both sides of the human body. So as to be beneficial to supporting the arm, and meanwhile, a flexible pad is arranged on the supporting cantilever part 5. The two supporting cantilever parts 5 are distributed in a splayed shape.

As shown in fig. 1 to 5, in order to ensure comfortable use in a sitting and lying state, a lifting adjusting sleeve 7 is sleeved on the front and rear swinging support 3, the upper end of the lifting adjusting sleeve 7 is higher than the upper end of the front and rear swinging support 3, the headrest 6 is hinged to the upper end of the lifting adjusting sleeve 7, the backrest 4 is connected to the lifting adjusting sleeve 7, a position locking piece 71 is arranged on the lifting adjusting sleeve 7, the position locking piece 71 is a bolt or the like, the position locking piece 71 abuts against the outer wall of the front and rear swinging support 3, or the position locking piece 71 is in threaded connection with any one of a plurality of threaded holes arranged on the front and rear swinging support 3.

The lift adjustment sleeve 7 has a detour 70 at the top thereof, and the headrest 6 is hinged to the detour 70, so that the headrest 6 has better support performance.

Next, the lift adjustment sleeve 7, the backrest 4 and the cantilever support portion 5 are integrally formed of plastic by injection molding. The backrest 4 is shaped into an inverted triangle, so as to be beneficial to the switching of the sitting and lying states. Or the width of the backrest 4 in the vertical direction is gradually reduced from the central position to both sides.
