Referring to FIG. 4 , the racing seat 400 includes a seat body 410 , a plurality of pressure sensors 420 , a plurality of air bags 430 , and an air bag control system 440 . The pressure sensor 420 is disposed on the seat body 410 for detecting a load applied to the seat body 410. The load is applied to the seat body 410, for example, by an occupant or a driver. Load. The air bag 430 is disposed in the seat body 410, and the air bag control system 440 is coupled to the air bag 430.

The above-mentioned racing seat is summarized as an actuating method, and FIG. 5 is the FIG. Flow chart of the method of operation of the racing seat. Referring to FIG. 5, when the pressure sensor 420 detects the load applied to the seat body 410, a sense signal is output correspondingly, and the airbag control system 440 receives the sensing signal, and then interprets the sensing accordingly. Signal to inflate or vent the air bag 430.

The racing seat 400 of the present invention is used to detect the load applied to the seat body 410 by the ride on the racing seat 400 by the pressure sensor 420 disposed on the seat body 410. Then, after the pressure sensor 420 detects the load, a sensing signal is transmitted to the airbag control system 440. After receiving the sensing signal, the airbag control system 440 will accordingly configure the air disposed in the seat body 410. The bag 430 is inflated or vented to support driving on the seat body 410.

For example, when the traveling direction of the car suddenly changes to the right, the center of gravity of the driving will move to the left side of the racing seat 400, and thus the partial load on the left side of the seat body 410 will increase. At this time, the pressure sensor 420 detects the increase amount of the left load, and inflates the air bag 430 on the left side to resist the centrifugal force caused by the car to the driving, and maintains the center of gravity of the driving. For driving in driving, the utility model has the function that the conventional technology cannot provide, that is, the load on the seat body 410 is detected by the pressure sensor 420 at any time to control the air bag 430 to provide corresponding support for driving. In order to avoid moving the center of gravity of the driving body away from the seat body 410 due to centrifugal force when the direction of travel of the vehicle changes. Therefore, the racing seat 400 of the present invention allows the driving to comfortably and safely operate the vehicle.

It should be noted that the pressure sensors 420 may also be arranged in an array of different densities for the surface topography of the seat body, for example, where the load on the seat body 410 is relatively dense, and then disposed in a denser manner. An array of pressure sensors 420. Conversely, where the seat body 410 is not subjected to loads or loads, an array of sparse pressure sensors 420 is configured. This allows the pressure sensor 420 to have the most effective area detection distribution on the seat body 410, so that the transmitted sensing signal can more accurately reflect the load on each part of the seat body 410. Get the most effective detection results. The air bag control system 440 also thereby precisely controls the amount of inflation and the amount of exhaust of each air bag 430, so that the air bag 430 produces a corresponding supporting effect for the load distribution on the seat body 410.

Between 442 and the air bag 430. When the controller 446 receives the sensing signal, the air bag 430 is inflated or vented via the main air passage 448 and the air passage 449 by controlling the air valve assembly 442 and the air pump 444. In the present embodiment, the configuration and operation mode of the air bag control system 440 are described by only one air passage 449 and one air bag 430. However, the present invention does not limit the number and configuration of the air bag 449 and the air bag 430, and the designer can The configuration and number of air ducts 449 and airbags 430 are varied as a function of the racing seat 400.

The check valve 442b and the sealing valve 442c are located in the air passage 449, wherein the check valve 442b is used to prevent the gas from flowing back from the air passage 449 to the main air passage 448, and the sealing valve 442c is used to discharge the gas of the air passage 449. Sealed. When the support valve 442a is opened, the seal valve 442c is closed, and the air pump 444 is actuated, gas can enter the air bag 430 via the main air passage 448 and the air passage 449. When the sealing valve 442c is opened, the gas in the air bag 430 flows to the sealing valve 442c via the air passage 449 and is discharged to the outside.

Figure 7 is a front elevational view of the racing seat of Figure 4. Referring to FIG. 7, the figure shows the distribution of the pressure sensor 420 and the air bag 430 on a bearing surface S in blocks.

Area 414. The pressure sensor 420 can also be divided into a left sensing group 422 and a right sensing group 424 in corresponding regions. Similarly, the air pockets 430 disposed in the seat body 410 can also be divided into a left airbag group 432 and a right airbag group 434.

When driving on the seat body 410, both the left and right sensing groups can detect the load applied to the seat body 410, and the airbag control system 440 transmits the pressure sensor 420 according to the pressure sensor 420. The sensing signal is emitted to inflate or vent the air bag 430 to maintain the center of gravity of the driving body. When the driving direction changes to the right momentarily, the driving body will tilt to the left side due to the centrifugal force. At this time, the load detected by the left sensing group 422 on the left sensing area 412 is greater than the right sensing. The load detected by group 414. Therefore, the airbag control system 440 inflates the left airbag group 432, and the airbags 430 of the left airbag group 432 are simultaneously inflated to support the driving of the body tilted left by the centrifugal force, thereby balancing the driving direction. The center of gravity of the driving body caused by an instantaneous change.

In summary, the racing seat of the present invention has a pressure sensor for detecting a load and an air bag for supporting the load after being inflated, so that the racing seat can detect the driving caused by the seat body at any time while the vehicle is running. The air bag is appropriately inflated or vented by the load to avoid the shift of the center of gravity of the driving body due to the change of the driving direction, so that the driving can comfortably and safely control the vehicle. Moreover, the pressure sensor has a flexible characteristic, and thus can be based on the seat body The shape is attached to the surface of the seat body without taking up extra space. In addition, the pressure sensor can be arranged on the bearing surface in an array or most effective area detection distribution, thereby analyzing the load distribution on the seat body, so that the racing seat can more accurately control the air bag inflation or exhaust. .

On the other hand, the present invention can also distinguish the bearing surface on the seat body into different sensing regions according to the relative position of the seat body, and the pressure sensor and the air bag can be distinguished into corresponding sensing. Groups and airbag groups. Therefore, the controller can be analyzed for the load conditions of different sensing areas, so that the air bag control system can inflate or row the corresponding air bag group according to the load detected by different sensing areas. gas.
