Abstract

This invention discloses a lumbar cushion includ ing a lumbar cushion front panel, a lumbar cushion back shell, an airbag module, a control panel, a fixing clip, and a vibration module. By providing a hook body, a hook slot, a latch slot, and a latch hook body, the front panel can be conveniently fixed to one side of the back shell. Reverse operation allows the front panel to be separated from the back shell, facilitating maintenance of equipment or components between the front panel and the back shell. By incorporating an air pump body, an airbag module, and a vibration module, the air pump body can inflate the airbag module to support the lumbar and back area of the driver. Vibrations generated by the vibration module can provide massage of varying intensities to the lumbar and back area of the driver, thereby improving the comfort of the driver.
