Abstract

Capteur anti-pincement (100) destiné à un élément de fermeture d'un véhicule à moteur, mobile entre une position d'ouverture et une position de fermeture. Le capteur anti-pincement (100) comprend un circuit (20) conçu pour générer un signal de mesure. Le circuit (20) présente un élément de détection (21) et un élément de mesure (22). L'élément de détection (20) permet de détecter un objet dans la zone de déplacement de l'élément de fermeture. Pour générer le signal de mesure, l'élément de mesure (22) coopère avec l'élément de détection (21). L'élément de détection (21) et l'élément de mesure (22) sont reliés par voie électrique. Le capteur anti-pincement (100) peut simultanément détecter un cas de pincement et effectuer une signalisation optique, notamment aux fins d'indication d'un cas de pincement ou du mode de fonctionnement de l'élément de fermeture.
