[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Reference Figure 1 and Figure 2 , an embodiment of the lumbar pillow of the present invention is proposed:

[0022] A lumbar pillow comprises a lumbar pillow body 1, a fixed connector 2, a first pin 6, a second pin 7, a third pin 8, a reset torsion spring 5, a telescopic member 4 and a rotating connector 3.

[0023] A plurality of fixing connector fixing holes 21 are provided on the rear side of the fixing connector 2, and the fixing connector 2 is screwed to the external structure through the fixing connector fixing holes 21. Two oppositely arranged first fixing connector holes 23 are provided on the top of the front side of the fixing connector 2, and a fixing connector connecting seat 22 is provided on the bottom of the front side of the fixing connector 2, and two oppositely arranged second fixing connector holes 24 are provided on the fixing connector connecting seat 22.

[0024] The rotating connector 3 is provided with four rotating connector fixing holes, and the lumbar pillow body 1 is provided with four body fixing holes. The rotating connector fixing holes and the body fixing holes are connected by screws, thereby fixedly connecting the lumbar pillow body 1 and the rotating connector 3. Two oppositely arranged rotating connector first connecting holes 32 are provided on the top of the rear side of the rotating connector 3. The first connecting hole 23 of the fixed connector and the first connecting hole 32 of the rotating connector are connected by a first pin 6, thereby rotatably connecting the top of the rotating connector 3 and the top of the fixed connector 2. A rotating connector connection seat 31 is provided on the bottom of the rear side of the rotating connector 3, and two oppositely arranged rotating connector second connecting holes 33 are provided on the rotating connector connection seat 31.

[0025] The return torsion spring 5 is sleeved on the first pin 6, and one side of the return torsion spring 5 is pressed on the fixed connection part 2, and the other side of the return torsion spring 5 is pressed on the rotating connection part 3. The return torsion spring 5 can make the lumbar pillow elastically follow the waist.

[0026] The bottom of the telescopic member 4 is provided with a first telescopic member connection hole 41. A second pin 7 connects the first telescopic member connection hole 41 with the second connection hole 24 of the fixed connector, thereby rotatably connecting the bottom of the fixed connector 2 to the bottom of the telescopic member 4. The top of the telescopic member 4 is provided with a second telescopic member connection hole 42. A third pin 8 connects the second telescopic member connection hole 42 with the second connection hole 33 of the rotating connector, thereby rotatably connecting the top of the telescopic member 4 to the bottom of the rotating connector 3. The telescopic member 4 is a telescopic pneumatic rod and is equipped with a locking switch that can be used to lock the telescopic member 4 in its extended or retracted state.

[0027] When in use, the locking switch is used to release the lock of the telescopic part 4, so that the lumbar pillow body 1 is completely unfolded under the action of the reset torsion spring 5. When the user uses it, the lumbar pillow body 1 is moved to the appropriate position and the telescopic part 4 is locked by the locking switch, so that the lumbar pillow can meet the usage needs of customers with different body shapes and different sitting postures.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
