Abstract
The present invention is a child seat detecting apparatus for detecting the presence of a child seat in a vehicle. The child seat detecting apparatus is a tension sensing device that is attached to a vehicle seat. The tension sensing device includes a bracket that is mounted to the vehicle seat. A moveable bar is retained by the bracket. The moveable bar is attached to the child seat. A sensor is mounted between the bracket and the moveable bar. The sensor is adapted to provide an electrical signal that is indicative of a magnitude of tension on the moveable bar. A spring is located between the bracket and the moveable bar. The spring biases the moveable bar away from the bracket.
