INVENTION: IMPROVED SAFETY BELT CLAMP APPARATUS AND OCCUPANT RESTRAINT SYTEM INVENTORS: R. PFEIFFER, R. L. STEPHENSON AND P. O. WEMAN An improved belt clamp apparatus in combination with a seat belt for a vehicle occupant safety restraint system comprising: a housing; a lever pivotably mounted in said housing, said lever having a clamping position and a non-clamping position with respect to a seat belt which is movable through said clamp apparatus; means biasing said lever to its non-clamping position, said lever being movable towards said belt to its clamping position .an response to a force above a predetermined amount applied to said belt in a first direction; clamping means provided on said lever for clampiny said belt to resist movement of said belt in said first direction in response to said force above a predetermined amount; first and second opposite surfaces on said clamping means; means on said first surface of said clamping means defining a planar contact area for contacting said belt, said first surface normally being out of contact with said belt; and pivot means associated with said second surface of said clamping means for directing pivotal movement of said clamping means with respect to said lever about a pivot axis directly opposite to said contact area, whereby said contact area is moved into substantially parallel engagement with the major plane of said seat belt in response to said force above a predetermined amount, thereby resising movement of said belt in said first direction. |
