[detailed description of the invention]
Below in conjunction with each accompanying drawing, the utility model will be further described.
Referring to Fig. 1 to Fig. 6, the chair that when layback of the utility model chair back, cushion reach also declines simultaneously, comprise chair frame 1, cushion 2, chassis overhang 3, also include front side link 4, rear side link 5, eccentric wheel 6 and spring assembly, described chair frame 1 as frame, cushion 2 as connecting rod, with front side link 4 and the common composition hinge four-bar of rear side link 5 double rocker mechanism, wherein, chair frame 1 is hinged by eccentric wheel 6 with front side link 4; Described chassis overhang 3 is hinged with chair frame 1 and front side link 4; Between chassis overhang 3 and chair frame 1, spring assembly is installed.
In preferred embodiment of the present utility model:
Described spring assembly comprises spring 7, spring stop 8 and spring pull bar 9, on described spring stop 8, there is perforation, described spring pull bar 9 comprises flange flange dish 91, the spring pull bar body of rod 92 and spring pull bar bearing pin A8, the spring pull bar body of rod 92 rear ends are that flange flange dish 91, front end are the spring pull bar bearing pin A8s vertical with its axis, spring stop 8 is fixed on chassis overhang 3, the spring pull bar body of rod 92 is through spring 7 and spring stop 8, and spring pull bar bearing pin A8 and chair frame 1 are hinged.
Described chair frame 1 forms L-shaped by the vertical chair back 11 and horizontal underframe 12, underframe 12 middle parts are fixed with chair frame rear pin shaft A5, front end successively vertical setting of types has the B8 that bores a hole under bearing pin A6 and chair frame before the B3 that bores a hole in chair frame, chair frame, and the B5 that bores a hole under chair frame rear pin shaft A5 and rear side link forms chain connection; B3 and the chassis overhang upper pin A3 composition chain connection of boring a hole in chair frame, the B8 that bores a hole under chair frame forms chain connection with spring pull bar bearing pin A8; Eccentric wheel 6 is fixed on the front bearing pin A6 of chair frame.
Described eccentric wheel 6 comprises eccentric wheel endoporus B6 and eccentric wheel outline circle A7, the central shaft disalignment of eccentric wheel endoporus B6 and eccentric wheel outline circle A7, under the installation reset condition of chair, the central shaft of the central shaft of described eccentric wheel endoporus B6 and eccentric wheel outline circle A7 is on same straight line, and described straight line is with vertical with the straight line of chassis overhang lower bearing pin A4 through chassis overhang upper pin A3.
Described front side link 4 has the B4 that bores a hole under bore a hole on front side link B2, front side link middle punch B7 and front side link from top to bottom successively, under bore a hole on described front side link B2, front side link middle punch B7 and front side link, bore a hole B4 respectively with cushion before bearing pin A2, eccentric wheel 6 and chassis overhang lower bearing pin A4 composition chain connection.
On described rear side link 5, have the B5 that bores a hole under bore a hole on rear side link B1 and rear side link, under bore a hole on rear side link B1 and rear side link, bore a hole B5 respectively with cushion rear pin shaft A1 and chair frame rear pin shaft A5 composition chain connection.
