The storage device stores a computer program, wherein the processor executes the computer program to achieve the above method for determining seat comfort.

In order to enable the reviewing committee to better understand the technical contents of the present invention, specific embodiments are described below.

Referring to FIG. 1 at the same time, the present invention provides a system 99 for determining seat comfort, which includes a pressure pad 2 and a computer main unit 3. The seat pad 2 includes a plurality of sensors 21, and the plurality of sensors 21 are electrically connected to the host computer 3. The plurality of inductors 21 are distributed on the seat pad 2, and the seat pad 2 includes a first region 22 and a second region 24.

Preferably, the plurality of inductors 21 are substantially evenly distributed on the seat pad 2, and the first region 22 and the second region 24 are substantially equal and adjacent to each other. The first region 22 is the thigh region and the second region 24 is the hip region.

Referring also to Figure 2, the system of the present invention primarily provides an assessment of the user's advice and comfort for the seat in which it is seated. When the user 100 sits on the seat 1 having the seat pad 2, the first region 22 and the second region 24 of the seat pad 2 respectively generate a first pressure value and a second pressure value (ie, the user's The pressure in the thigh area and the hip area is transmitted to the host computer 3.

The computer host 3 of the present invention includes a processor 31 and a storage device 32. The storage device 32 stores a computer program 321 and a comparison database 322. The processor 31 executes the computer program 321 to achieve various functions (described in detail below with reference to FIG. 3).

Please refer to the flowchart of FIG. 3, which shows the method for determining the comfort of the seat according to the present invention, which is as follows:

Step S301: Receive a first pressure value and a second pressure value.

As described above, when the user 100 sits on the seat 1 having the seat pad 2, the first region 22 and the second region 24 of the seat pad 2 respectively generate a first pressure value and a second pressure value (also It is the pressure of the user's thigh area and hip area) transmitted to the host computer 3.

Step S302: providing a seat suggestion for the seat to be tested according to the first pressure value and the second pressure value.

The processor 31 executes a computer program 321 to calculate a ratio of the first pressure value to the second pressure value. For example, as shown in FIG. 4, the ratio of the first pressure value to the second pressure value of the first region 22 and the second region 24 of the seat pad 2 is 1:5.1. However, it should be 1:4 according to the usual appropriate standard, so it can be preliminarily judged that the seat is too short, and the seat is recommended to be given to the user 100.

Step S303: Provide an interface to receive at least one parameter information.

The processor 31 executes a computer program 321 to provide an interface 4 (shown in FIG. 5) for inputting parameter information such as the height of the user, the actual height of one of the seats to be tested (seat height), and an actual depth ( Seat depth), an actual back tilt (back tilt), or an actual lumbar height (height height).

Step S304: Determine the comfort of the seat to be tested according to the first pressure value and the second pressure value.

For example, Figure 6A shows an appropriate standard seat pressure distribution with an average comfort of 3.6 points. If the seat cushion 2 of the user is seated, the seat pressure distribution is as shown in Fig. 6B, and there are three levels of excessive pressure, and the comfort is 3.57 = 3.6 - (0.01X3).

Preferably, the comfort C is substantially calculated according to the following formula: when 3.5 ≦ P ≦ 7, C = -P ² +10.1P - 21.51, where P is the first pressure value divided by the second pressure value. When P>7 or 1<P<3.5, C is a fixed value of 0.1.

Step S305: Determine a seat information according to the at least one parameter information, and determine whether the seat information meets the seat recommendation.

According to the parameter information input by the user, the computer host can calculate a seat information. According to the height of the user, the length of the lower leg can be calculated, and the height of the required seat can be estimated according to the length of the lower leg. According to the height of the seat in the parameter information input by the user, it can be known whether the seat 1 is too high. Or too low. For example, according to the parameter information of FIG. 5, the height of the average knee pocket to the ground is 37 cm for a user with a height of 165 cm, and the seat height (40 cm) of FIG. 5 is too high. In step S305, it is judged whether or not the result coincides with the aforementioned seat recommendation calculated by the first pressure value and the second pressure value.

Step S306: If the result of the above determining step is "No", a warning is displayed to inform the user that the data needs to be re-imported or re-measured.

If the determination in the step S305 is "NO", it may be that the posture of the user 100 is deviated when the test is performed, and the test is not accurate. Therefore, a warning is displayed in step S306 to inform the user that the data needs to be re-introduced or re-measured.

Step S307: Transfer the parameter information to a comparison database.

As shown in FIG. 1, the storage device 32 also includes a comparison database 322. Although the illustrated comparison database 322 and the computer program 321 are located in the same storage device 32, the present invention is not limited to the present invention, and the comparison database 322 and the computer program 321 may be located in different storage devices 32, respectively. The parameter information input in step S303 can be transmitted to the comparison database 322.

Step S308: Access the comparison database to update the formula.

The more the testees, the more parameter information is transmitted to the comparison database 322, so the more parameter information that can be collected by the present invention, the adjustment formula of the above C can be adjusted according to the quantity of the collected parameter information, for example, Adjust according to the statistical distribution curve.

The above steps 301-308 do not limit the order. For example, step S303 can also be performed before step S301. Therefore, the above embodiments are not intended to limit the present invention.

Further, although the above embodiment is exemplified by the seat height, it is not limited to the present invention, and the measured portion may be other such as a lumbar support, a seat back or the like. In addition, the seat proposal may also include (please refer to FIG. 1) the seat height H (ie, the height of the seat surface 11 to the ground), the seat depth D, the inclination of the seat back 12, or the waist height h.

To sum up, the present invention, regardless of its purpose, means and efficacy, shows its distinctive features of the prior art. You are requested to review the examination and express the patent as soon as possible. It should be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the invention is intended to be limited by the scope of the claims.
