Shoulder Harness
The shoulder harness webbing is attached to a retractor which is located on the B-pillar post for the front seat and on the rear package tray for the rear seat. This retractor is designed to let the webbing freely move in or out at all times, except during vehicle deceleration, when it is automatically locked by a mechanically actuated inertia sensor. The center lap safety belts do not have retractors.
The front shoulder harness is guided through the web guide which is mounted on the B-pillar and inside of the scuff plate/center pillar trim panel.
The webbing then passes through a guide above and behind the occupant's shoulder which directs the webbing at the proper downward angle over the occupant's shoulder and chest and attaches to the lap safety belt buckle.
