Description
Technical field
The invention belongs to the Furniture manufacture field, be specifically related to a kind of seat of new structure 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 forms, in order to improve comfort level, the general adjusting device of regulating the back bracket angle of inclination that all can arrange on the chassis, 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 such 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 at present seat of these control modes, with respect to the fixing nonadjustable seat of backrest, because 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 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 because load is excessive fracture, 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, existing seat, during the backrest hypsokinesis, seat support is synchronously hypsokinesis also, and like this, when human body was sat on the seat, shank also can be lifted very highly, and when backrest hypsokinesis angle was very large, shank will be very uncomfortable.In order to overcome the problems referred to above, the applicant has applied for that in 2009 name is called the patent of invention (patent No.: 200910214106.0) of " a kind of seat of seat support sliding to drive backrest to incline ", the technical scheme that this patent discloses is by the be connected interlock that realize backrest hypsokinesis and cushion body of backrest bottom with cushion body rear portion, thereby reach the comfortable purpose of user, but the connector of this technical scheme is for being fixedly mounted on cushion body rear portion, because the cushion body generally can only move forward and backward, can not move up and down, during backrest hypsokinesis action, the bottom meeting height of formation drop that is connected with the cushion body, when moving forward and backward, the cushion body can only rely on the deformation of connector or cushion body to realize interlock, because the deformability of connector or cushion body is generally all very limited, so backrest independently uses the angular adjustment when regulating also very limited.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in design, backrest angle to regulate the seat of the effective new structure seat support sliding to drive backrest to incline of more flexible, backrest and cushion-linkage.
The object of the present invention is achieved like this: a kind of seat of new structure 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, rotatable back bracket (5) upper end that is installed in, described backrest (6) middle part, described seat support (4) comprises carriage (40) and is installed in the cushion body (41) that carriage (40) is upper and can relative carriage (40) move forward and backward, between carriage (40) and cushion body (41), also be provided with the positioner (42) of control cushion body front and back position, it is characterized in that: the rear portion of described cushion body (41) is movably hinged a connection piece (3), the other end of connector (3) is movably articulated in the below of backrest (6), two connected pivot pin about the two ends of described connector (3) had respectively, the below of described backrest (6) is provided with a mount pad, comprise heavy stand (70), the cover plate (71) that is connected with heavy stand (70), cover plate (71) is installed on the heavy stand (70) by screw, two groups of bearing blocks (72) about being provided with between heavy stand (70) and the cover plate (71), bearing (73) is installed in the bearing block (72), and two connection pivot pins are hinged in the bearing (73) about connector (3) one ends; The rear portion of described cushion body (41) is provided with another mount pad, the loam cake (81) that comprises groove (80), is connected with groove (80), loam cake (81) is installed on the groove (80) by screw, two groups of positioning seats (82) about being provided with between groove (80) and the loam cake (81), another group bearing (83) is installed in the positioning seat (82), and two connection pivot pins are hinged in another bearing (83) about connector (3) other end.
The described bearing that is installed in bearing block (72), the groove (80) also can be tube-in-tube structure.
Be provided with the torsion spring (84) that cushion body (41) is moved forward by twisting force when the stressed hypsokinesis of backrest (6) in the mount pad at described cushion body (41) rear portion, be provided with spring base (85) in the described groove (80), torsion spring (84) is installed in the spring base (85), torsion spring (85) one ends are fixed in the locating hole that is opened on the spring base (85), and the other end is fixed in the draw-in groove (30) that is opened on the connector (3).
Described cushion body (41) upper surface is coated with screen cloth or leather or cushion.
The adjusting device (7) at described adjusting back bracket angle of inclination is one to be installed in the backguy adjusting device on the handrail (9).
Good effect of the present invention is: connector rotatably is hinged on respectively the rear portion of cushion body and the below of backrest, backrest hypsokinesis angle changes and the cushion body moves forward and backward when forming interlock, the variation that produces aspect height just can be passed through the rotation flexible modulation of connector, rather than relies on the elastic deformation of connector or cushion body.Adopt the seat of this structure, the hypsokinesis angle of backrest can be regulated by mobile cushion body, also can realize by the rotation of connector regulating, angular adjustment is more flexible, and when cushion body front and back position locks, backrest can also carry out separately angular adjustment, improves the flexibility of the use of backrest, and comfortableness is better.
As a further improvement on the present invention, in the mount pad at cushion body rear portion, be provided with the torsion spring that the cushion body is moved forward by twisting force when the stressed hypsokinesis of backrest, the convenient position of regulating the cushion body, in the adjustment process, the release of positioner elder generation when the stressed hypsokinesis of backrest is regulated, utilizes the torsional force urges cushion body reach of torsion spring, when backrest resets, reset by moving behind the connector drive cushion body again.
