Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind can increase relaxing for human lumbar
The soft linkage Lumbar of lumbar fatigue is effectively relieved in adaptive.
To achieve the above object, the utility model provides following technical solution: a kind of soft linkage Lumbar, including installation
Lumbar plate on the chair back and the chassis for installing seat cushion, the lower end of the Lumbar plate are provided with the first fixing seat, and described
One fixing seat is mounted on the chair back, and idler wheel baffle is provided at the upper end of the Lumbar plate, and the idler wheel baffle is mounted on the chair back
On, the upper end rotation of the Lumbar plate is provided with idler wheel, and the idler wheel cooperation is slidably mounted on idler wheel baffle, the Lumbar plate
Upper end be connected with steel cable, one end of the steel cable connects Lumbar plate, and the other end is provided with steel cable connector box, the steel cable connector
Box is fixedly mounted on cushion, is provided with steel wire between the chassis and steel cable connection box, one end of the steel wire is fixed on bottom
On disk, the other end of steel wire is worn in steel cable connector box, and the steel cable wears one end and steel wire position in steel cable connector box
It is connected in one end in steel cable connector box.
The utility model is further arranged to: the lower end of the Lumbar plate is provided with bolt, and the bolt and first are fixed
Seat is cooperatively connected.
The utility model is further arranged to: being provided at one end of Lumbar plate upper end on the steel cable and is mounted on chair
Second fixing seat of back, the steel cable are arranged through the second fixing seat.
The utility model is further arranged to: third fixing seat, the third fixing seat and steel are provided on the chassis
Line is connected close to the one end on chassis.
The utility model has an advantage that the protrusion of Lumbar plate plays the feeling for holding up and embracing to human body waist, can
The comfort for increasing human lumbar, is effectively relieved lumbar fatigue, by being equipped with for idler wheel and idler wheel baffle, makes it possible to improve
The operating function that the upper end of Lumbar plate slides up and down can be avoided steel cable and pulling Lumbar plate by the setting of the second fixing seat
When there is the case where steel cable offset, by the easy installation process of steel wire and chassis of the setting of third fixing seat, pass through first
The setting of fixing seat and bolt improves the efficiency that Lumbar plate is mounted on the chair back.
