Chair cushion pressure relief control method for adjusting pressure and controlling pressure time according to body weight

The present invention relates to a chair cushion pressure relief control method, in particular to a chair cushion pressure relief control method for adjusting pressure and controlling pressure time according to body weight.

Most modern people use computers in the office, and according to the survey, everyone sits in a chair in the office for at least 6 hours a day. In addition, for example, e-sports players, when they focus on the game, even longer than people sitting in office chairs. However, no matter what, the seat cushions used are all made of sponge or foam of different materials, and then decorated with PU cloth on the exterior packaging. Therefore, when sitting on the seat cushion or seat for a long time, no matter what The buttocks, the back of the thighs or the skin between the back of the seat cushion will be compressed for a long time, which will further reduce the blood fluidity of this part. For long-term sitting for a long time, it will cause poor blood circulation in the lower limbs.

Another example is the well-known Taiwanese patent I524865. Although it discloses an inflatable air cushion body cushion device that provides air permeability, multiple single points of pressure are applied to the part where the hips and thighs are in contact with the cushion seat. Therefore, For sedentary people, it is still unable to improve the problem of poor blood circulation in the stressed parts.

Conventional office seats or gaming seats are all made of polyurethane (PU) sponge or related materials.

. Accordingly, the control method for adjusting the pressure according to the body weight of the present invention can be completed by the above-mentioned method.

Please refer to FIG. 2A and FIG. 2B, which are timing diagrams of controlling pressure according to time according to the present invention. Figure 2A represents the control of inflation and deflation of the A and B airbags with four sets of control times. Figure 2B shows the timing chart of alternating inflation and deflation of the A and B airbags under different pressure values at different levels. In Figure 2A, the airbags of group A are controlled to perform the second control time after the first control time is reached, and the first control time and the second control time are repeated after the second control time is reached; the airbags of group B are controlled to be in the third control time When the fourth control time is reached, the fourth control time will be carried out. When the fourth control time is reached, the third control time and the fourth control time will be repeated. The four groups of control time are continuously carried out, and the two groups of airbags A and B can be continuously controlled. Perform inflation and deflation actions to achieve the effect of releasing and relaxing the pressure on the body and the chair cushion, and further improving the blood circulation of the body.

Furthermore, after the airbags of group B are inflated to the saturation state of the first predetermined pressure at the initial inflation time, when the airbags of group A are depressurized during the first control time, the airbags of group B are maintained at the first predetermined pressure for a delay control time. In the supported state, waiting for the airbags of group A to be inflated during the second control time, and the airbags of group B are deflated. The deflation time is S _B seconds, which is the third control time. When the third control time is reached, that is, when the deflation time is reached, the airbags of group B are inflated, and the airbags of group B are inflated to the supporting pressure saturation state of this step pressure and maintained at the pressure value, and the inflation maintenance time is The fourth control time.

The length of the control time can be set by the user, that is, how long it takes for the two sets of airbags A and B to deflate from the first predetermined pressure value to the second predetermined pressure respectively, and how long it takes to set by the user The time makes the two groups of airbags A and B inflated from the second predetermined pressure value to the second predetermined pressure respectively. In an embodiment of the present invention, the second control time is a percentage relationship of the first control time, and the fourth control time is a percentage relationship of the third control time. In another embodiment of the present invention, the second control time is N times the first control time, and the fourth control time is N times the third control time, where N is a positive number. For example, A first control group airbag relief S _A second time, a second pneumatic control time was S _A N times the second time, the third control group B S _B airbag second relief is inflated The fourth control time is N times the time of _{SB seconds.} For example, the first control time S _A and the third control time S _{B are} between 20 seconds and 120 seconds. If S _A =S _B =30 seconds and N=10 as an example, the second control time and The fourth control time is 10*30=300 seconds. Further, in one embodiment of the present invention, the control delay time may be calculated to determine a time to determine the third control after S _B seconds, for example, the control delay time = 1/2 * N * S B seconds, the above formula is as follows: Airbag pressure relief time of group A = S _A seconds (first control time) Airbag inflation time of group A = S _A seconds * N times (second control time) Airbag pressure relief time of group B = S _B seconds (third control time) Airbag inflation time of group B=S _B seconds*N times (fourth control time)

Please refer to FIG. 3, which is a block diagram of the cyclic control pressure of the present invention. The four sets of control times for inflation and deflation can be set in a cyclic manner, including setting the number of cycles C for continuous cycling for a predetermined number of times or setting the cycle time T for continuous cycling for a predetermined period as settings, which can be set according to the control time of the first to fourth groups The total cycle time increases or decreases according to demand. This additional cycle time T or C, number of cycles, a first set of time S to time _A in seconds and the third set of S _B calculated on the basis of seconds, can be set to a multiple, or by a percentage value for the number of seconds. The independent setting of the cycle time T or the number of cycles C increases the flexibility of time pressure control, and increases or decreases the time according to the user's needs to control the number of times of inflation or decompression of the two sets of airbag tubes. Taking the set number of cycles C as an example, when the airbag A releases the pressure S _A seconds*C in the first control time, the airbag B maintains the pressure value of this step, and the airbag A is inflated when the airbag reaches the second control time, and the second control time The time is maintained for the time of S _A seconds * N * C, the B airbag is depressurized during the third control time, and the pressure relief time is S _B seconds * C. When the B airbag reaches the fourth control time, it is inflated, and the fourth control time is maintained S _B seconds * N * C time, continue to circulate in this order. For example, if C is three times the number of cycles, a first control time is 30 seconds S _A, N 2, second control time to maintain the second SA * N = 30 * 2 = 60 seconds, and the first control time 30 Seconds plus the second control time to maintain 60 seconds and repeat the cycle 3 times. Therefore, the airbag A will alternately inflate and deflate for a total of (30+60)*3=270 seconds. In another embodiment, if the set cycle time T of 240 seconds, a first control time of 20 seconds S _A, N is 3, the second control time to maintain the second S _A * N = 20 * 3 = 60 seconds, and The first control time is 20 seconds and the second control time is maintained for 60 seconds for a total of 80 seconds. Therefore, the airbag A will alternately perform a cycle of inflating and deflating a total of 240/80=3 times. Accordingly, the time control pressure control method of the present invention can be completed by the above-mentioned method.

As shown in Figure 4, when the pressure control device is activated, the pressure control device starts to inflate, and at the same time inflate Group A airbags and Group B airbags. After a period of initial inflation time, the inflation reaches the supporting pressure of this stage pressure (the first predetermined pressure). ) After the saturation state, the airbags of group B are timed for a delay control time to maintain the airbags of group B at the first predetermined pressure, and the airbags of group A first release the pressure for SA seconds to the second predetermined pressure. This pressure relief time is the first control time , Wherein the second predetermined pressure is set in a range of less than 50~200 (mmHg) according to the first predetermined pressure. When the first control time is over, that is, when the deflation time is reached, the airbags of group A are inflated, and the airbags of group A are inflated to the supporting pressure saturation state of this step pressure and maintained at this level.

, And the time that the inflation is maintained is the second control time, and the second control time is maintained for N*S _A seconds. In the second control time when the airbags of group A are inflated, the airbags of group B are depressurized and maintained for S _B seconds, which is the third control time. When the third control time is over, the airbags of group B are inflated and maintained for N*S _B seconds, which is the fourth control time. In addition, the delay control time can be set to 1/2*N*S _B second. According to this, the setting of adjusting pressure and controlling pressure time according to body weight of the present invention can be completed.
