Abstract
The utility model relates to a chair back adjuster for seat units. A terminal batten is fixedly connected with the upper ends of a left and a right longitudinal arching battens, a base is fixedly connected with the lower ends of the left and the right longitudinal arching battens, and a plurality of transversal battens are fixedly connected with the middle parts of the left and the right longitudinal arching battens. The upper end of one longitudinal traction batten arranged at the middle part is fixedly connected with the terminal batten, and the lower end is hinged with an eccentric point of a turbine end face arranged on the base through a male pin. A scroll bar driven by a hand wheel through a shaft is engaged with the turbine. The chair back gains arching when the hand wheel is rotated, so a mold surface of the utility model used as a bearing surface for human bodies is changed. Sitting people has comfortable feeling.

Description
The utility model relates to a kind of Adjuster for chair back that is used for a tool, particularly a kind of Adjuster for chair back that is used for driver's seat.
In the prior art, leaning against of driver's seat and bus seat can be regulated elevation angle degree thereafter, but can not regulate the profile that leans against the human body supporting surface, is difficult to adapt to various sitting posture requirements.
The purpose of this utility model is to provide a kind of Adjuster for chair back, can the adjustment seat tool leans against the profile to the human body supporting surface, and is comfortable during seat to adapt to the different sitting postures with it of different people to leaning against the requirement of profile, to increase work efficiency.
In order to achieve the above object, the utility model adopts following technical proposals: lean against in this Adjuster for chair back and the prior art that skeleton is the same to include a grid framework that is made of vertical lath and transverse slats.Be characterized in: two laths are the arch camber lath about in vertical lath, fixedly connected with a root termination lath in their upper ends, and mid portion is fixedlyed connected with each bar transverse slats respectively, and fixedly connected with base in the lower end; A middle vertical lath is fixedlyed connected with the terminal lath for traction lath, its upper end, and the lower end is articulated in an eccentric point place that is installed in the turbine end face of base by pin; Mesh by driven off by shaft scroll bar and turbine by a handwheel.In the overcoat that the present tool of this Adjuster for chair back installation leans against, and handwheel is exposed.During use, the seat person rotates handwheel, then affects the traction lath, makes the arch camber of arch camber lath, thereby changes the profile that leans against seat person supporting surface, and the person sits more comfortablely to make the seat.
The utility model has conspicuous advantage compared with prior art: this Adjuster for chair back can change the profile that leans against the human body supporting surface easily, adapts with the physiologic radian of human spine, and the person sits more comfortablely to make the seat.Be particularly useful for driver's seat, the needs in the time of can driving according to it regulate leaning against its degree of support; Be used for Work seat, make the worker sit comfortablely, increase work efficiency; Also be applicable to the seat of bus seat and daily life and rest.This Adjuster for chair back is simple in structure, and cost is low, and is easy to use.
Fig. 1 is the structural representation of an embodiment of the utility model.
Form schematic diagram when Fig. 2 is the utility model arch camber in use.
An optimum implementation of the present utility model is: referring to Fig. 1, the structure of this Adjuster for chair back is: about the upper end of two arch camber laths 2 fixedly connected with a root termination lath 1, fixedly connected with base 10 in the lower end, mid portion is fixedlyed connected with four reinforcement laths 3,5 with four transverse slats 6 respectively.Fixedly connected with terminal lath 1 in the upper end of a middle traction lath 4, top and transverse slats 6 of being close near the reinforcement lath 3 of terminal lath 1 and its and on reinforcement lath 6 fixedly connected, and the lower end is articulated in the eccentric part of turbine 8 end faces by pin 7.The above-mentioned fixedly connected rivet that all adopts connects.Near the reinforcement lath 3 of terminal lath 1 than other strengthen laths 5 slightly width more greatly, other three reinforcement laths 5 all cover on the corresponding transverse slats 6.The material of arch camber lath 2, traction lath 4, transverse slats 6, terminal lath 1, reinforcement lath 3,5 is spring steel.Base 10 is flat casket bodies that the iron sheet riveted becomes.Two bearings 9 are installed in the base 10 are come bolster 12, scroll bar 11 on the axle 12 and turbine 8 engagements, axle 12 1 ends extend to base 10 outsides, the fixedly connected handwheel 13 of its terminal.
