Embodiment 3

[0113] The difference between Embodiment 3, Embodiment 4, Embodiment 5, Embodiment 6 and Embodiment 1 is mainly that the specific structure of the transmission part 40 is different.

[0114] Specifically, embodiment 3, such as Figure 16 with Figure 17 As shown, the gas spring 12 can be directly installed under the seat cushion 3, or can be indirectly assembled under the seat cushion 3 through a connecting part such as a bottom plate, and this technical solution is not limited. Achieving transmission through a rack and pinion is a form of realization of the transmission part 40. Specifically, the gas spring 12 is stretched to drive the connecting arm 41 forward, and the end of the connecting arm 41 is connected to the connecting rack 42, which drives the connecting rack 42. Pushing forward, the swing tooth 43 naturally rotates under the forward drive of the connecting rack 42, driving the swing of the lumbar support 5. The slotting direction of the long groove 11 is also th...
