[0102] Example 2, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, including chair foot assembly 1, seat cushion 3, armrest assembly 4 and backrest 5, the sleeve pipe 6 top of armrest assembly 4 is provided with rocker 8, and the front end portion of rocker arm 8 is provided with revolving pin 32 and the rear of backrest 5. The lower part of the seat cushion 3 is fixed with the base plate 13, the lower part of the base plate 13 is fixedly connected with the upper part of the chair foot assembly 1, the fixed control frame 31 at the rear of the base plate 13 is connected with the front part of the air rod 12, and the air rod The afterbody of 12 is provided with connecting pin 33 and is connected with one end of connecting arm 9, and the other end of connecting arm 9 is provided with swinging pin 17 and movably inserts in the swinging groove 18 of sleeve pipe 6 bottoms...

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 and 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 the...

Abstract

The invention relates to the field of design and manufacture of seats, in particular to a lumbar support seat. The lumbar support seat is characterized by comprising a lumbar support and a gas spring,wherein the lumbar support realizes a close fit with a waist and a back of a human body during the movement of the waist and the back through the expansion and the contraction of the gas spring so asto provide continuous uniform force. The invention aims to overcome the defects in the prior art and provides the lumbar support seat. When a user moves back and forth on the seat, the lumbar supportcan be in close fit with the waist and the back of the human body to do synchronous movement and is in real-time fit with the waist, so that the supporting force to the waist position of the human body is increased.
