Figure 5 Specifically, six groups are arranged here; when the massage mechanism is arranged, the housing of the driving source (generally a driving motor) of the massage mechanism can be fixedly installed at a suitable position on the internal framework of the seat, and the six groups of massage mechanisms are arranged in two rows with three groups as one row; the automobile seat can achieve a better massage effect, is simple in structure, and is beneficial to reducing production cost.

[0040] The automobile seat can be implemented according to the following working principle when in use:

[0041] When the passenger leans on the seat back, the air pump can be controlled to start and stop by the seat controller, the air bag body 401 is inflated through the air pipe, the massage assembly 3 is pushed to make the ejection action, and the return spring 5 is compressed. When the passenger leaves the seat back, the air pump opens the exhaust valve, the air bag body 401 is deflated, the return spring 5 returns under the guidance of the rotating rod 2, and the massage assembly 3 is pushed to retract. The strength of the mechanical massage head to push out can be detected by the pressure sensor pad to detect the pressure of the passenger leaning thereon, so that the set program of the controller is realized. Under the action of the driving motor, the rotating rod 2 is driven to rotate, so that the massage assembly 3 is driven to rotate. The controller can also control the driving motors of the multiple groups of massage mechanisms to make independent forward and reverse rotation, so as to provide more massage modes and more directly and effectively massage the muscle groups.
