Abstract

L'invention concerne un dispositif de détection (1) de position d'un siège (70) par rapport au châssis (60) d'un véhicule, qui comprend un rail solidaire de l'un du siège ou du châssis, un support (20) qui est solidaire de l'autre du siège (70) ou du châssis (60), et une roue (30) qui est libre en rotation par rapport au support (20) et qui est en liaison de roulement sans glissement avec le rail (20). Le dispositif (1) comprend en outre un capteur (40) qui est apte à mesurer la position angulaire de la roue (20), et un microcontrôleur (50) connecté au capteur (40) et apte à calculer le nombre de tours et la position angulaire de la roue (20) depuis une position de référence par rapport au rail (10), à partir des mesures fournies par le capteur (40).The invention relates to a device (1) for detecting the position of a seat (70) relative to the chassis (60) of a vehicle, which comprises a rail integral with one of the seat or the chassis, a support ( 20) which is integral with the other of the seat (70) or the frame (60), and a wheel (30) which is free to rotate relative to the support (20) and which is in rolling connection without sliding with the rail (20). The device (1) further comprises a sensor (40) which is able to measure the angular position of the wheel (20), and a microcontroller (50) connected to the sensor (40) and able to calculate the number of revolutions and the angular position of the wheel (20) from a reference position relative to the rail (10), from the measurements provided by the sensor (40).
