Title
(EN) OCCUPANT DETECTION SYSTEM
(FR) SYSTEME DE DETECTION D'OCCUPANT
Abstract
(EN)
An occupant detection system (10) comprises an electric field sensor (100) in the seat bottom (42) of a vehicle seat (3) for discriminating objects on the seat (3), and a seat weight sensor (200) for sensing the force upon the seat (3). The electric field sensor (100) discriminates normally seated occupants (5) from other seating conditions, and disables a restraint actuator (39) unless a normally seated occupant (5) is present. The seat weight sensor (200) disables the restraint actuator (39) if the force upon the seat is less than a threshold.
(FR)
La présente invention concerne un système de détection d'occupant (10) comprenant un détecteur de champ électrique (100) placé dans le fond du siège (42) d'un siège d'automobile (3) de façon à distinguer les objets posés sur le siège (3) et un détecteur de poids sur le siège (200) capable de détecter la force s'exerçant sur le siège (3). Le détecteur de champ électrique (100) fait la distinction entre des occupants normalement assis (5) et les autres conditions d'occupation du siège, et met hors fonction un actionneur de sangle (39) à moins qu'un occupant normalement assis (5) soit présent. Le détecteur de poids sur le siège (200) met hors fonction l'actionneur de sangle (39) si la force s'exerçant sur le siège est inférieure à un seuil.
