Description
Technical field
The invention belongs to furniture and make the field, be specifically related to a kind of seat of seat support sliding to drive backrest to incline.
Background technology
Present seat, generally by chair pin, chassis, be installed in seat support and the back bracket on the chassis and the backrest that is installed on the back bracket is formed, in order to improve comfort level, the general adjusting device of regulating the back bracket angle of inclination that all can on the chassis, be provided with, to regulate the angle of inclination of backrest, (patent No.: technical scheme 200820051448.6), this technical scheme have adopted a kind of easy to operate backguy adjusting device to control the seat of backrest inclination angle as Chinese utility model patent disclosed " a kind of swivel chair reclining lifting wire-controlled apparatus ".Certainly, also have alternate manner directly to control the seat at back bracket angle of inclination, this control technology is comparatively ripe, here do not describing in detail one by one, adopt the seat of these control modes at present, with respect to the fixing nonadjustable seat of backrest, because of regulating at its angle of inclination, the user can be adjusted to a position that is fit to own angle as required, improves comfort level.But this present class seat, when changing the backrest inclination angle, the center of gravity of seat is moved after also can producing along with the angle change of backrest, when mass centre changing was excessive, the stressed increase in the rear end of chair pin might produce fracture because of load is excessive, or chair disequilibrium and toppling over, so generally all can limit the hypsokinesis angle during design, to prevent the fracture of chair pin or to topple over the range of tilt angles of the backrest that this just must limit.In addition, conventional seat, during the backrest hypsokinesis, seat support is hypsokinesis synchronously also, and like this, when human body was sitting on the seat, shank also can be lifted very highly, and when backrest hypsokinesis angle was very big, shank will be very uncomfortable.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in design, backrest inclination angle scope is big, can change center of gravity with backrest inclination, uses the seat of comfortable seat support sliding to drive backrest to incline.
The object of the present invention is achieved like this: a kind of seat of seat support sliding to drive backrest to incline, comprise chair pin 1, chassis 2, be installed in seat support 4 and the back bracket 5 on the chassis 2 and be installed in backrest 6 on the back bracket 5, described chassis 2 is provided with the adjusting device 7 of regulating the back bracket angle of inclination, it is characterized in that: rotatable back bracket 5 upper ends that are installed in, described backrest 6 middle parts, on described seat support 4 comprises carriage 40 and is installed in carriage 40 and the cushion body 41 that can relative carriage 40 moves forward and backward, the underside of the rear portion of this cushion body 41 and backrest 6 is hinged, be respectively equipped with gathering sill 410 on the fore-and-aft direction of the left and right sides of described cushion body 41 bottoms, carriage 40 is provided with the roller 400 that is installed on the gathering sill 410.
Also be provided with the positioner of control cushion body front and back position between described carriage 40 and the cushion body 41.
Described positioner comprises the tooth bar of being located on the carriage 40 402 and is located at the latch 413 that drives by button 412 on the cushion body 41, but the tooth position that is positioned at tooth bar 402 of latch 413 clutches.
Be provided with the elastic pulling force device of control cushion body 41 front and back displacements between described carriage 40 and the cushion body 41.
Described elastic pulling force device comprise be located at the connecting portion on the carriage 40 and be located at the connecting portion on the cushion body 41 and be installed in the carriage connecting portion and cushion body connecting portion between extension spring 45, the place ahead of the connecting portion of connecting portion on carriage 40 on the cushion body 41 wherein.
Described seat support 4 is provided with the governor motion of the pulling force of regulating the elastic pulling force device, is included in the mounting groove 403 offered on carriage 40 fore-and-aft directions, the slide block that moves forward and backward 43 that mounting groove 403 is provided with and is installed in the knob 44 that is used to control slide block 43 sliding forces on the carriage 40 front end installing holes 46; Connecting portion 430 on the carriage 40 is located at slide block 43 rear ends, and described extension spring 45 1 ends are installed on the connecting portion 430 of slide block 43, and the other end is installed on the connecting portion 414 of cushion body 41; Described knob 44 has an eccentric wheel 440, and the outer rim of this eccentric wheel 440 is resisted against the reach position of the front end of slide block 43 with adjusting slider 43.
Described slide block 43 is a T shape piece, is respectively equipped with connecting portion 430 at rear end the right and left of T shape piece, and the place ahead correspondence that is positioned at slide block connecting portion 430 on the cushion body 41 is provided with connecting portion 414, and the connecting portion of the right and left is provided with extension spring 45 respectively.
Described cushion body 41 upper surfaces are coated with screen cloth or leather or cushion.
The adjusting device at described adjusting back bracket angle of inclination is a backguy adjusting device 7.
Good effect of the present invention is: with the rotatable back bracket upper end that is installed in, backrest middle part, seat support by carriage be installed in carriage on and the cushion body that can relative carriage moves forward and backward form, the rear portion of cushion body and the underside of backrest are hinged, this structural design, when the relative carriage of seat support moves forward, meeting drives the lower end reach of backrest, and backrest is that the center produces rotation with the middle part tie point, and the realization hypsokinesis is regulated.Because seat support reach, center of gravity also can move forward, so move after can offsetting the center of gravity of backrest hypsokinesis generation, the chair center of gravity is not changed substantially.Adopt this structural design, the range of tilt angles of backrest increases, if single employing backguy adjusting device can realize backrest hypsokinesis 26 degree, and seat can also keep balance, chair pin in normal design load scope: adopt single seat support reach can regulate backrest hypsokinesis angle 15 degree, then both combinations can realize that backrest hypsokinesis on a large scale 41 degree and seat can also keep balance, chair pin in normal design load scope.In addition, adopt seat support reach control backrest inclination angle, this kind mode, seat support smoothly moves ahead not can be with backrest inclination, so shank can not raise, and uses comfortable.
As a further improvement on the present invention, the cushion body and the carriage of seat support are connected by gathering sill and roller structure, and front and back displacement luck row is level and smooth.Be provided with the positioner of control cushion body front and back position between carriage and the seat support, can move forward and backward the position to seat support and fix, thus the angle of inclination size of control seat.The past more reach of seat support, the angle of inclination of backrest is big more.
Be provided with the elastic pulling force device that control cushion body moves forward and backward between carriage and the cushion body, can prevent that the cushion body from arbitrarily moving on carriage, during the reach of cushion body, the pulling force that must overcome the elastic pulling force device could move, when positioner discharges and seat support when not stressing, the elastic pulling force device can also make the cushion body automatically reset.In addition, seat support is provided with the elastic pulling force device of regulating the elastic pulling force size, is fit to different people and selects suitable pulling force, such as people of imposing stature, selects bigger pulling force, and comparatively petite people selects less pulling force.
