Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, and in particular to a massage lumbar support and a seat having the massage lumbar support. Background Technology

[0002] In daily work, maintaining a sitting posture for extended periods can lead to lower back pain and other health problems. To address this, people have invented various types of lumbar supports and cushions for chairs.

[0003] Typical massage lumbar supports are difficult to use quickly and effectively to massage the user's waist, thus reducing the product's massage efficacy and practicality. In particular, existing lumbar supports cannot effectively conform to the human waist, resulting in extremely poor massage effects and significantly affecting the product's functionality. In addition, when the user does not need a massage, the massage head of existing massage lumbar supports remains in a protruding state, so the user's waist is still pressed against the massage head even in a relaxed state, resulting in poor comfort. Summary of the Invention

[0004] The purpose of this utility model is to provide a massage lumbar support and a seat with the massage lumbar support. The position adjustment mechanism can drive the massage device to move back and forth between the extended position and the retracted position. When the massage device is in the extended position, the massage device can fit closely to the human body to improve the massage effect. When the massage device is in the retracted position, the pressure of the massage device on the human waist is eliminated, improving the user's comfort.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a massage lumbar support, comprising... The lumbar support body is equipped with a control module, a power supply module, and a control unit electrically connected to the control module.
