Occupant detection system

摘要

An occupant detection system comprises an electric field sensor in the seat bottom of a vehicle seat for discriminating objects on the seat, and a seat weight sensor for sensing the force upon the seat. The electric field sensor discriminates normally seated occupants from other seating conditions, and disables a restraint actuator unless a normally seated occupant is present. The seat weight sensor disables the restraint actuator if force upon the seat is less than a threshold.
