Referring to fig. 4 and 5, the present embodiment provides a method for adjusting the height of an airbag module.

S1, setting any air bag as a fixed inflatable air bag, wherein the fixed inflatable air bag is the air bag which is inflated firstly when the air bag group is opened every time, and setting one air bag with the optimal height as the fixed inflatable air bag according to the habit of a user.

And S2, opening an air valve of the fixed inflatable air bag to inflate the fixed inflatable air bag for X seconds, wherein the X seconds are the filling duration of the fixed inflatable air bag, and it can be understood that the inflation can be stopped at any time in the process from the beginning of inflation to the filling, namely, the bulging position of the air bag group can be the bulging of the fixed inflatable air bag, the bulging height can be adjusted, and the bulging height can be understood as the air bag inflation saturation.

S3, after the fixed inflatable air bag is filled with air, referring to the figure 4, if the air bag group needs to be adjusted to roll upwards, inflating the air bag above the fixed inflatable air bag for Y seconds; referring to fig. 5, if the airbag set needs to be adjusted to roll downward, the airbag located below the fixed inflatable airbag is inflated for Y1 second, where Y second is less than the time period for which the airbag above the fixed inflatable airbag is full, and Y1 second is less than the time period for which the airbag below the fixed inflatable airbag is full. It can be understood that the inflation can be stopped at any time during the process from the inflation of the upper air bag to the inflation of Y seconds or the process from the inflation of the lower air bag to the inflation of Y1 seconds, and at this time, all the air valves are in a closed state.

It should be noted that if the fixed inflatable airbag is the topmost end of the longitudinally arranged airbag group, the airbag group cannot roll upward any more, and similarly, if the fixed inflatable airbag is the bottommost end of the longitudinally arranged airbag group, the airbag group cannot roll downward any more.

And S4, if the air bag group rolls upwards, after the air bag above the air bag is inflated for Y seconds, the air valve of the fixed inflatable air bag is opened to deflate, and meanwhile, the air bag above the air bag is continuously inflated for A seconds. If the air bag group rolls downwards, after the air bag at the lower part is inflated for Y1 second, the air valve of the fixed inflatable air bag is opened to deflate, and meanwhile, the air bag at the lower part is continuously inflated for A1 second. It can be understood that the airbag group can stop inflating at any time in the process of continuously inflating the upper airbag for a second or continuously inflating the lower airbag for A1 second, at this time, all the air valves are in a closed state, and the swelling height of the upper airbag or the lower airbag is adjustable.

In the step, the air valve for fixing the inflatable air bag is opened for deflation, and the whole deflation process does not need any energy-consuming power and is only deflation by natural extrusion during use. For example, the airbag group is mounted on a seat back, the air discharge amount of the fixed inflatable airbag is only extruded by the back of a user, when the upper airbag is filled, the bulging position of the airbag group is adjusted in the longitudinal direction, and meanwhile, the air amount of the fixed inflatable airbag is more suitable for the back curve of the user, so that the experience feeling of the user is improved.

And S5, when the upper air bag or the lower air bag is full of air, all the air valves are closed at the same time, namely the upper air bag or the lower air bag stops inflating, and the fixed inflatable air bag stops deflating.

According to the steps, when the air bag group needs to move upwards, the fixed inflatable air bag firstly bulges normally, then the bulging height of the overlapped part of the fixed inflatable air bag and the upper air bag is increased, meanwhile, the non-overlapped part of the upper air bag also begins to bulge, then, the upper air bag bulges completely, and the air quantity of the fixed inflatable air bag is discharged to the human body and cannot bulge. The state that the bulge rolls from bottom to top is simulated in the process that the bulge position of the whole air bag group moves, a massage effect is achieved on a user, and the experience of the user is greatly improved.

It will be appreciated that if the inflated position is moved to the upper air bag to which the inflatable air bag is fixed, and if it is desired to move up or down, then the upper air bag which is now inflated is treated as the fixed inflatable air bag, and S3 to S5 are repeated. It should be noted that the values of X, Y1, A1 can be adaptively adjusted according to the size of the balloon actually used, the rate of inflation/deflation of the air valve, the personal habit, etc.

When the user felt the height of tympanites too high, when needing to bleed the gasbag promptly, the pneumatic valve of each gasbag all opens simultaneously, and the extrusion through the user is simultaneously bled to suitable height, all pneumatic valves are closed simultaneously to when making the adjustment tympanites the inflation saturation, user's back is laminated more with the shape that back contact one side formed to whole gasbag group, improves use comfort.
