Vehicles equipped with the Occupant Classification System (OCS) include a belt tension sensor. See Fig 1. This sensor is integral to the passenger side front seat belt lower anchor which is secured to the lower B-pillar, on the passenger side. See Fig 2. The belt tension sensor consists of a molded plastic housing, a metal seat belt anchor loop, and a short pigtail wire. The electronic circuitry of the belt tension sensor is concealed and protected within the molded plastic housing.
