[0028] The first connecting structure is connected to the mounting plate 1, and the second connecting structure is connected to the fan 4. The connection between the first connecting structure and the second connecting structure is used to connect the mounting plate 1 and the fan 4.

[0029] Specifically, in use, the air bag 3, fan 4, and mounting plate 1 are installed inside the backrest of the vehicle seat. The mounting plate 1 is fixed to the backrest, and the end of the first ventilation hole 5 on the mounting plate 1 away from the air bag 3 faces the ventilation hole provided on the backrest. The bottom wall of the mounting groove 2 is provided with a first ventilation hole 5 that communicates with the ventilation hole on the backrest of the vehicle seat. This means that the first ventilation hole 5 does not directly contact the ventilation hole on the backrest, but the airflow entering the backrest through the ventilation hole can enter the first ventilation hole 5 through the gap between the backrest and the mounting plate 1. The air bag 3 is installed in the mounting groove 2 of the mounting plate 1. The fan 4 is connected to the mounting plate 1 through a first connecting structure and a second connecting structure, so that the air bag 3 is sandwiched between the mounting plate 1 and the fan 4, so that the side of the air bag 3 facing away from the fan 4 contacts the bottom wall of the mounting groove 2, connecting the first ventilation hole 5 and the second ventilation hole 14, so that the side of the air bag 3 facing the fan 4 contacts the fan 4, connecting the third ventilation hole 9 with the air inlet 19 of the fan 4.

[0030] When fan 4 is activated, airflow enters through the gap between the backrest and the passenger, passes through the ventilation holes on the backrest, and then sequentially enters the air bag 3 through the first ventilation hole 5 and the second through hole 16. From there, air flows through the air bag 3, the third through hole 16, and the air inlet 19 into fan 4, finally exiting through the air outlet 20 of fan 4. This creates a flowing airflow between the passenger and the backrest, providing a cooling sensation. The elimination of the need for additional air ducts reduces the overall size of the seat ventilation assembly, thereby minimizing the internal space occupied by the seat ventilation assembly within the vehicle seat backrest and facilitating the placement of other electrical components within the seat backrest.

The line connecting the three second connecting holes 12 forms an equilateral triangle, which makes the connection between the connecting plate 10 and the mounting plate 1 more stable.

[0038] In one embodiment, the side of the boss 6 facing the fan 4 is flush with the side of the air bag 3 facing the fan 4. Specifically, the flush alignment of the side of the boss 6 facing the fan 4 with the side of the air bag 3 facing the fan 4 facilitates the installation of the connecting plate 10, reduces the gap between the connecting plate 10 and the air bag 3, and further reduces the overall size of the seat ventilation assembly.
