Abstract
The utility model relates to a seat lumbar rest arranged in a backrest of a seat for adjusting arch degrees of the backrest, which comprises an actuating mechanism and a control mechanism, wherein the actuating mechanism comprises a basic frame and an arch assembly; the control mechanism comprises a handle assembly and a drag rope; the handle assembly comprises a handle, a driving wheel and a driven wheel. One end of a steel cable of the drag rope is connected with the driven wheel of the handle assembly, and the other end is connected with the actuating mechanism. When the handle rotates, the driving wheel drives the driven wheel to drive the drag rope to move so that the arch assembly moves; the arch degrees of the backrest of the seat are adjusted by changing the arch degrees of the arch assembly.
Description
One, technical field
The utility model is a kind of parts in the seat, and especially a kind of waist that is installed in backrest inside holds up mechanism.
Two, background technology
The waist holder is a kind of parts in the seat, and it is installed on the backrest inside of seat, and the occupant can regulate the degree that backrest arches upward by regulating the waist holder, to reach the effect of adjusting sitting posture, slowing down lumbar fatigue.
Existing waist holder generally comprises arch upward mechanism and controlling organization, and under the manipulation of controlling organization, the degree of arching upward of the mechanism that arches upward is changed, thereby has regulated the degree that backrest arches upward.
The shortcoming of prior art is the controlling organization troublesome poeration, and the handle of controlling organization need rotate a few could realize arching upward fully of waist holder.
Three, summary of the invention
The technical problems to be solved in the utility model is the problem of the controlling organization troublesome poeration (handle need rotate a few could realize that the waist holder arches upward fully) of existing waist holder.
The technical solution of the utility model is described below:
The utility model comprises executing agency and controlling organization.
Executing agency comprises pedestal and the assembly that arches upward.Pedestal is used for the waist holder is installed on chair framework; The assembly that arches upward is installed on the pedestal, and can move with respect to pedestal.Executing agency can have different version, no matter which kind of version, the degree that arches upward of the assembly that arches upward changes along with the motion of the assembly that arches upward.
Controlling organization comprises handle assembly and drag-line.Drag-line is a kind of part commonly used on the automobile, and it comprises flexible pipe and steel wire rope, in the end of flexible pipe and steel wire rope joint is arranged all.Handle assembly comprises handle, driving shaft, driving wheel, driven pulley, spring and housing and cover plate.Steel wire rope one end of drag-line is connecting executing agency, and the other end is connecting the driven pulley of handle assembly.
The utility model when work, the staff rotary handle, driving shaft and driving wheel by linking together with handle drive the driven pulley rotation, and drive the assembly motion of arching upward by drag-line, and then change the degree that arches upward of the assembly that arches upward.
The utility model compared with prior art has following useful effect:
Because steel wire rope one end of drag-line is connecting the driven pulley of handle assembly, when driven pulley was rotated by handle drives, when little angle (as 0.5 circle) was changeed in one of handle rotation, steel wire rope had a bigger stroke, and drive the mechanism that arches upward and arch upward fully, solved the problem of controlling organization troublesome poeration.

Five, the specific embodiment
Now in conjunction with the accompanying drawings embodiment of the present utility model is elaborated.
Fig. 1 is the schematic diagram of embodiment of the present utility model.1,2,3,4,5,6,7,8 have constituted controlling organization among the figure, and wherein 1 is handle, and 2 is driving shaft, and 3 is driving wheel, and 4 is driven pulley, and 5 is spring, and 6 is housing, and 7 is cover plate, and 8 is drag-line.Wherein part 1,2,3,4,5,6,7 has constituted handle assembly.Handle 1 connects with driving shaft 2 usefulness splines; Driving shaft 2 is fixedly connected with driving wheel 3; Driven pulley 4 and driving shaft 2 matched in clearance; Spring 5 is installed in the cavity of housing 6 and driving wheel 3; Driving shaft 2 relies on the hole of housing 6 and cover plate 7 to support and the location.
On housing 6, there is mounting ear 61,61 to be used to install hose coupling 83 (see figure 2)s of drag-line 8.
Part 9,10,11,12,13,14 has constituted executing agency, and wherein part 9,14 has constituted pedestal, and part 9 is a longeron, and part 14 is a fixed block, and part 9 and 14 is solidly installed; Part 10,11,12,13 has constituted the assembly that arches upward, and part 10 is the arch arm, and part 11 is a support arm, and part 12 is the top back, and part 13 is a slide block.Part 10 two ends connect with part 13 and 12 hinges respectively, and part 11 two ends connect with part 10 and 14 hinges respectively.
The hose coupling 85 of drag-line 8 is installed on fixed block 14, follows the steel cable termina 84 of drag-line 8 at slide block 13 first line of a couplet.
Fig. 2, Fig. 3, Fig. 4 are the supplementary notes to Fig. 1.
Fig. 2 is the schematic diagram of driven pulley and drag-line relation, and among the figure, 81 is the steel cable termina of drag-line 8, and 82 is the steel wire rope of drag-line 8.On driven pulley, have groove G.Steel cable termina 81 is installed in the hole of driven pulley 4, has steel wire trough F on driven pulley, is used to hold steel wire rope 82.
Fig. 3 is the cross sectional representation of driving wheel 3, jagged ABCD on the driving wheel 3 among the figure, and this breach is used to place the plug-in unit E of driven pulley 4.
Fig. 4 is the schematic diagram of driven pulley 4, and plug-in unit E is arranged on the driven pulley 4, is used to be plugged in the breach ABCD of driving wheel 3.
The course of work of the present utility model is such:
When turning handle 1, drive driving shaft 2 and driving wheel 3 rotations by spline, driving wheel 3 makes driven pulley 4 rotations by the plug-in unit E that its breach ABCD drives driven pulley 4; During driven pulley 4 rotations, steel cable termina 81 rotates thereupon, 82 motions of pulling steel wire rope, steel cable termina 84 correspondingly moves, thereby driving slide block 13 moves up and down along longeron 9, make the hinge axis of support arm 11, and then promote arch arm 10 and 12 motions of top back, thereby reach the effect of regulating the degree that arches upward around itself and fixed block 14.
