Characterized in that, the both sides of the cushion and backrest are respectively arranged with elastic force handrail, one end and the cushion of elastic force handrail connect
Connect, the other end is connected with backrest.
As a further illustration of the above scheme, the backrest is provided with the swinging supporter being hinged with cushion, bullet
Power handrail is connected with swinging supporter.
Further, the swinging supporter is connected with the angular adjustment dress at its change backrest angle of inclination of driving
Put, angle regulator includes the regulation gas bar being connected between swinging supporter and cushion and controls to adjust gas bar open locking shape
The regulation gas lever switch of state.
The regulation gas lever switch includes rotating handles and is connected to rotating handles and adjusts the switch guy wire between gas bar,
Regulation gas lever switch is moved, regulation gas bar released state is made by switch guy wire, user leans on after, swinging supporter rotation
Turn, regulation gas bar is packed up；Regulation gas lever switch is moved again, and regulation gas lever switch released state, user are made by switch guy wire
For the back of the body not when leaning against on the chair back, gas bar opens under the atmospheric pressure of regulation gas bar goes back to original position swinging supporter top.
The swinging supporter is U-shaped backrest, and the two side ends of U-shaped backrest are arranged with fixed axostyle, one end of elastic force handrail
Axis hole one corresponding with fixed axostyle is provided with, handrail limited screw is provided with axis hole one, handrail limited screw is fixed on
On dead axle bar, trim is provided with outside handrail limited screw.
The cushion is provided with handrail rotating base, and handrail rotating base is provided with axis hole two, elastic force handrail be provided with
Axostylus axostyle corresponding to axis hole two, axostylus axostyle is inserted in axis hole two, and is positioned by snap ring, the axostylus axostyle of elastic force handrail is stuck in handrail rotation
, again will not be locked while making elastic force handrail without departing from handrail rotating base in base.
The elastic force handrail material can be plastic cement or hardware, elastic force handrail have toughness can with backrest hypsokinesis and
Stretching.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is：
The utility model uses sets elastic force handrail respectively in the both sides of cushion and backrest, makes backrest is relative to sit
During pad regulation angle of inclination, elastic force handrail can also stretch therewith or resilience, and good support is provided for the back of the body of user, hand, begins
Comfortableness is kept eventually, is met base of principle of human engineering, can effectively be extenuated fatigue.
