摘要

Improvements in the object of the patent nº9800393 by an improved anti-pinching system based on the modification of light conductivity in the optical fiber intended for automobile raiser.; The improved anti-pinching system (4) is based on the modification of the light conductivity of an optical fiber for raiser for the car and comprises a coating (5) arranged on the inside (6) of the frame (1) of the door (2 ) incorporating a second coating (10) and a sensor (7) comprising at least one optical waveguide (8) extending through the profile (9) of the casing (10). The conductor (8) extends helically around the outside of the profile (9) and can be said profile (9) of circular section or a tubular profile provided with a second circular profile coaxial (12) or be configured for wire bundle (11) which can be arranged twisted with the conductor (8).
