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.

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.
