Abstract
An anti-pinch system for an electric seat includes a plurality of infrared sensing modules, a seat cushion hose, a footrest hose, a pressure sensor, at least one linear actuator, a central processing unit, a power module and a control module. When the user operates the electric seat to act, the plurality of infrared sensing modules and the pressures sensor synchronously sense whether an obstacle is under the electric seat. If an obstacle exists under the electric seat, the central processing unit will control the at least one actuator to stop or to reversely act. When the user cannot perceive obstacles by themselves, the electric seat can be automatically prevented from pinching obstacles, thus avoiding damaging the obstacles or the electric seat.
