[0015] Preferably, one end of the take-up wheel is fixedly connected to a spring, and the other end of the spring is fixed to a lumbar pillow.

[0016] The effect achieved by the above components is: the belts on both sides are pulled out, so that the belt-receiving wheel rotates, thereby the spring contracts.

[0017] Preferably, the spring sleeve is arranged on the surface of the rotating shaft, and the two belts pass through the lumbar pillow.

[0018] The effects achieved by the above components are: the Velcro is separated from the bed, the spring is reset, and the belt is driven to reset.

[0019] Preferably, rectangular grooves are provided on both sides of the lumbar pillow, and the belt is located on the inner wall of the rectangular grooves.

[0020] The effect achieved by the above components is that the belt is conveniently taken out by setting the rectangular groove.

[0021] The beneficial effects of the utility model are:

[0022] The utility model provides an adjustment component. When the hardness of the lumbar pillow needs to be adjusted, the U-shaped rods on both sides are retracted through the adjustment mechanism, so that the steel bars are bent and then close to the top of the inner wall of the air cavity, so that the user can feel the different hardness. The user can adjust the distance of the steel bars close to the top of the inner wall of the air cavity to adjust the hardness to meet the usage habits of customers. This solves the problem that when using the lumbar pillow, some users are accustomed to a harder lumbar pillow, while some users are accustomed to a softer lumbar pillow. The lumbar pillow only makes the lumbar pillow bulge by injecting gas into the air cavity, so that the hardness cannot be adjusted, and thus cannot meet the usage habits of users.
