As of the present utility model preferred, described elasticity is connected and fixed device and comprises the elastic caoutchouc post being fixedly connected with described backrest base, bolt and nut, described bolt one end is fixed in described elastic caoutchouc post, the other end is spirally connected through described chair back base and described nut, bolt and nut by metal material are firmly fixed together backrest base and seat support base, can be not out of shape, the described elastic caoutchouc post of being made by soft elasticity material is providing sufficient elastic force to make described backrest base that the displacement of upper and lower all directions all around can occur on described seat support base simultaneously.
As of the present utility model preferred, described elastic caoutchouc post is circular platform type, large near one end diameter of described backrest base, improves like this adhesion strength of described elastic caoutchouc post to described backrest base, adds stiff stability.
As of the present utility model preferred, described elasticity is connected and fixed device and comprises the elastic caoutchouc post being fixedly connected with described backrest base, screw and nut, described nut is embedded in described elastic caoutchouc post, described screw is spirally connected through described chair back base and described nut, by the screw and nut of metal material, backrest base and seat support base are firmly fixed together, can be not out of shape, the described elastic caoutchouc post of being made by soft elasticity material is providing sufficient elastic force to make described backrest base that the displacement of upper and lower all directions all around can occur on described seat support base simultaneously.
As of the present utility model preferred, described elasticity is connected and fixed device and comprises the joint pin of being made by soft elasticity material, be wrapped in the spring outside described joint pin, screw and nut, described joint pin and both ends of the spring connect respectively and backrest base and seat support base, described screw is fixedly arranged in described chair back base, described screw and described nut are spirally connected, joint pin possesses the effect of guiding, stability while increasing described backrest base displacement, and joint pin is owing to adopting soft elasticity material to make, elastic force is provided together with spring, make described backrest base that the displacement of upper and lower all directions all around can occur on described seat support base.
As of the present utility model preferred, described screw becomes circular platform type near one end of described Flexible Connector, large near the section diameter of described Flexible Connector, promotes the stability of described screw in described seat support base inside.
As of the present utility model preferred, described elasticity is connected and fixed and in device, comprises two described joint pins, described joint pin not only provides elastic force and has guide effect, described jockey comprises two described joint pins can provide support force better when described chair back bar is subjected to displacement, promotes seat stability.
To sum up, the utlity model has following beneficial effect: this use new structure is simple, easy to implement.When user uses, described backrest base is stable to be connected on described seat support base, owing to having adopted described elasticity to be connected and fixed device, make described backrest base upper and lower multiple displacements of putting down all around to occur on described seat support base along with human posture's variation, thereby backrest and the headrest of realizing seat can be adjusted angle automatically, without manual adjustments, increase comfortableness and the convenience of seat.
