The expansion unit 142 may be configured to operate more closely (pressurized) to the upper body side of the occupant during the collision of the vehicle, through this configuration can minimize the injury of the occupant with the operation of the airbag.

On the other hand, the drive of the upper body fixing device 100 as described above may be controlled by the following method.

The control method of the upper body fixing device 100 senses the speed of the vehicle and supplies a different degree of pressure supplied to the expansion unit 142 according to the set driving speed of the vehicle to press (close) the upper body side of the occupant. It may be made to be determined. In this case, the supply of pressure may be controlled by detecting the degree of expansion of the expansion part 142 so as to be pressed (closely) according to the body shape of the occupant, that is, whether the expansion part is in close contact with the pressure set at the side of the upper body.

An example of a method for controlling the pressure supplied to the expansion unit 142 will be described with reference to the flowchart illustrated in FIG. 5A. The process S1 of fixing the upper body of the occupant according to the traveling speed of the vehicle 1 may be performed by the following process.

First, when the driving of the vehicle 1 starts, it is checked whether the driving is performed at the set initial speed (S11). When the vehicle is driven at the set initial speed, the controller 110 may be controlled to supply the pressure set from the pressure providing unit 141 to the expansion unit 142 (S12). If the set initial speed is not reached, it can be controlled so that pressure is not provided.

Thereafter, the volume of the expansion part 142 is increased by the pressure provided to sense the degree of one area of the expansion part 142 is in close contact (pressurization) to the upper body side of the occupant (S13). That is, it may be controlled to detect the repulsive force (S13) that the expansion unit 142 receives by the upper body side of the occupant. The repulsive force may be measured by using a pressure sensor or by detecting an overload occurring in the pressure providing unit 141. On the other hand, it may be configured to detect the repulsive force generated in the expansion unit 142 by using a generally known detection means. In this case, when the repulsive force does not reach the set value, it can be controlled so that the provision of pressure is continued.

When it is confirmed that the pressure is provided at a value equal to or more than the set repulsive force, the operation of the pressure providing unit 141 is stopped to control the supply of pressure (S14).

Then, it is checked whether the running speed of the vehicle increases above the set initial speed (S15). In this case, when the running speed of the vehicle is increased, it is controlled to provide more pressure by operating the pressure providing unit 141 (S12). Then, in the case of maintaining the range of the set initial velocity, it is controlled to maintain the state where the supply of pressure is stopped (S14). On the contrary, when the driving speed of the vehicle is slowed down than the set initial speed, the vehicle is controlled to discharge the pressure supplied to the expansion unit 142 (S16).

Meanwhile, as illustrated in FIG. 5B, the vehicle 1 may be configured to detect a boarding state of the occupant before the vehicle 1 is operated and to control the pressure supplied to the expansion unit 142 (S2).

Check whether the occupant is seated through the sensing unit 120 provided in the seat 11 (S21), if it is confirmed that the boarding is made, the pressure is provided from the pressure providing unit 141 to the expansion unit 142 It is controlled to be (S22).

As described in the upper body fixing step (S1) according to the above described driving speed, the volume of the inflation section 142 is increased by the pressure provided thereafter, so that one region of the inflation section 142 is the upper body of the occupant. The degree of close contact (pressure) is detected (repulsive force) (S23). In this case, when the repulsive force does not reach the set value, it can be controlled so that the provision of pressure is continued.

Then, when it is confirmed that the pressure is provided at a value equal to or more than the set repulsive force, it is controlled to stop the operation of the pressure providing unit 141 to stop the provision of pressure (S24).

Thereafter, the upper body fixing step (S1) according to the above described traveling speed may be controlled to be further performed.

By the above process, the seat 10 provided with the upper body fixing device 100 which fixes the upper body of the occupant may be controlled to fix the upper body of the occupant through various steps as shown in FIG. 6.

For example, when the vehicle travels at a speed of about 80 km / h, the volume of the expansion unit 142 increases to the same degree as in FIG. 6 (a), and when the vehicle runs at a speed of about 100 km / h, It may be controlled to increase the volume of the inflation portion 142 to the same extent as b). When the vehicle travels at a speed of about 130 km per hour, the volume of the expansion unit 142 increases to the same degree as in FIG. 6C, and when the vehicle runs at a speed of about 150 km per hour, FIG. 6D. It can be controlled to increase the volume of the inflation portion 142 to the same degree.

In this case, when the inflation portion 142 is positioned inside the guard 12a, the guard 12a may press the upper body side of the occupant by increasing the volume of the inflation portion 142.
