摘要

Improvements introduced in the object of patent 9800393 for No. improved anti-pinching system based on the modification of the light conductivity of a fiber optic raiser for the car. The invention relates to modifications to the object of the consistent main patent have a means based on measuring light conductivity to design the limit switches in the raiser systems for the automobile, so that at the top frame corresponding window has embedded or not inside the inner seal of said frame, a fiber optic conductor which when pressed by the upper edge of the glass, modify the value of light conductivity and is detected such modification by opening the corresponding electronic supply circuit of the motor and immobilizing the same, achieving a smooth stop.
