ABSTRACT:
A guide loop assembly for deflecting a restraint belt from a retractor to a diagonal position across the occupant torso includes a guide loop frame having a slot defined by an anvil surface over which the belt slides during winding and unwinding of belt from the retractor. The guide loop frame also has an elongated aperture which receives an anchor bolt to mount the guide loop frame on the pillar for pivotal movement and as well as limited vertical movement. A support frame is pivotally mounted by the anchor bolt and has a clamping bar pivotally mounted thereon for movement between a normal position spaced away from the anvil surface of the guide loop frame and a clamping position clamping the belt against the anvil surface. A spring biases the clamping bar to the normal position spaced away from the anvil surface and also urges the clamping bar against the guide loop frame to position the guide loop frame at the upward limit of its vertical movement. The imposition of an occupant restraint load on the belt moves the guide loop frame vertically downward and pivots the clamping bar downwardly to clamp the belt against the anvil surface of the guide loop frame with a clamping force increasing as a function of the increasing load on the belt.
