Problems solved by technology
[0005] However, this type of traditional manual lacing driver usually uses an adjustment handle to drive the lacing drive gear to rotate, which is affected by the large rotational torque of the handle, making manual operation more laborious
For this reason, some manufacturers adopt the form of gear sets to reduce the rotational moment. However, when the frame side plates inside the relatively narrow seat back are arranged, it is not easy to arrange because of the large structure and cumbersome installation operations. chair factory complained

The invention discloses a manual tiepiece actuator. The manual tiepiece actuator includes a shell, a driven internal gear, a driving external gear, a handle and a tiepiece, wherein the driven internal gear is rotatably arranged in the shell, a tiepiece hanging structure for fixing the tiepiece is arranged on the driven internal gear, the driving external gear meshes with the driven internal gear, the handle is used for driving the driving external gear, one end of the tiepiece is fixed to the tiepiece hooking structure, and the other end of tiepiece is used for being connected with a lumbar seat-adjusting supporting device. According to the manual tiepiece actuator, by the adoption of a form of an internal and external gear set, not only is labor saving achieved through the internal and external gear set, but also through a nesting mode, the internal and external gear set only occupies space for one driving external gear, and structural facilitation and miniaturization and an integrated structure form are achieved.
Description
technical field [0001] The invention relates to the technical field of seat lumbar support, in particular to a manual tension driver. Background technique [0002] With the development of science and technology in the field of vehicle transportation, people have higher and higher requirements for vehicle ride comfort. A simple manual adjustment support technology for the waist and back of the seat in the vehicle field has also emerged as the times require, and has gradually been applied in the market. [0003] In the past, this kind of manually adjusted seat lumbar support technology usually used gears coaxial with the handle to drive the traction wire rope to adjust the position of the spring frame used to support the backrest sponge cushion to realize the local convexity of the seat backrest surface. Up or down, so as to realize the support effect on the lower back of the human body. By turning the handle, the gear that rotates coaxially with the handle is driven. The ge...
