Abstract

The present invention discloses a seat adjusting method and a seat adjusting system capable of actively adjusting a user'"'"'s sitting posture and comfort according to the body weight of different users. Stress sensors are provided for detecting a stress distribution situation of a seat support surface. Airbags are buried into the support surface for actively changing the level of the support surface in order to increase a contact area between the support surface and the user, and the stress distribution situation can be matched with an expected ratio to provide the best ergonomic support effect to users.

Claims

1. A seat adjusting method, comprising the steps of:

burying a plurality of airbags into an internal side of a support surface, wherein an inflated or deflated state of each airbag is controlled by an inflation/deflation control device;

detecting a stress distribution situation of a seat support surface by a plurality of stress sensors;

outputting a detected stress of each stress sensor to a control unit to produce a corresponding stress parameter, wherein the control unit is connected to a built-in memory for preloading an optimal stress parameter ratio;

using the control unit to compare an actual stress parameter ratio obtained by the stress sensor with an optimal stress parameter ratio, when a user sits in a seat; and

performing an adjusting procedure for inflating or deflating each airbag by the inflation/deflation control device according to a comparison result, wherein the comparison procedure and the adjusting procedure are carried out in cycle, and stopped until the actual stress parameter ratio is matched with the optimal stress parameter ratio.

2. The seat adjusting method of claim 1, wherein after the actual stress parameter ratio is matched with the optimal stress parameter ratio, a corresponding stress parameter of each stress sensor is recorded in the built-in memory, such that if the same user sits in the seat again, the control unit will not perform the comparison procedure, but will directly drive the inflation/deflation control device to perform the adjusting procedure for inflating/deflating the airbags, and will stop the adjusting procedure when the inflated/deflated mode of each airbag corresponds to the recorded stress parameter.

3. The seat adjusting method of claim 1, wherein the control unit is connected to a portable storage device, such that after the actual stress parameter ratio is matched with the optimal stress parameter ratio, the corresponding stress parameter of each stress sensor is recorded into the portable storage device and provided for a convenient carry for the user.

4. The seat adjusting method of claim 1, wherein the inflation/deflation control device further performs a continuous or intermittent dynamic inflation/deflation control to specific airbags.

5. A seat adjusting system, comprising:

a plurality of airbags, buried into an internal side of a seat support surface;

a plurality of stress detectors, for detecting a surface stress distribution situation of a seat support and outputting a stress parameter;

an inflation/deflation control device, connected to each stress detector for actively controlling an inflation or a deflation of each airbag according to the stress parameter, and the inflation/deflation control device comprising a control unit connected to each stress detector for obtaining the stress parameter, a pump connected to the control unit, an air valve assembly connected to the control unit, an operating interface connected to the control unit, a built-in memory connected to the control unit for preloading an optimal stress parameter ratio; and

a power supply device, for supplying electric power required for the operation of the seat adjusting system.

6. The seat adjusting system of claim 5, wherein the inflation/deflation control device further comprises a portable storage device connected to the control unit.

7. The seat adjusting system of claim 5, wherein the stress sensor is installed between each airbag and the support surface.

8. The seat adjusting system of claim 5, further comprising a ventilation pipeline between each airbag and the inflation/deflation control device, and the stress sensor is installed on the ventilation pipeline.

9. The seat adjusting system of claim 5, wherein the inflation/deflation control device includes an electric port connected to the control unit for performing a data transmission.

10. The seat adjusting system of claim 5, wherein the inflation/deflation control device includes a wireless transmission interface connected to the control unit and provided for a data transmission.

11. The seat adjusting system of claim 5, wherein the support surface has an electrothermal component installed at an internal side of the support surface.

12. The seat adjusting system of claim 5, wherein the support surface includes a plurality of ventilation holes disposed thereon, an air passage disposed inside the seat for circulating an air flow and connecting the air passage with an air blower, such that when the air blower produces an air flow, the air flow passes through the air passage and the ventilation holes on the support surface for achieving a ventilation effect.

13. The seat adjusting system of claim 5, further comprising an auxiliary medical detector, and the auxiliary medical detector includes a cushion laid on the seat and a plurality of precision stress detectors densely distributed on the cushion.
