ABSTRACT:
A seatbelt clamp for locking a seatbelt to restrain a vehicle occupant and prevent elongation of the seatbelt due to tightening of loops remaining on a seatbelt retractor is provided. The clamp comprises two operation plates, adjustable relative to each other, which are slidably mounted on a base plate. The base plate has a case on its lower end housing a fixed clamping jaw and a movable clamping jaw, the latter being biased by a spring into a non-clamping position. The two plates also are normally biased by a spring into a non-clamping position. If an emergency results, which throws the passenger against the seatbelt, causing the tension in the seatbelt to exceed a predetermined level of force, the two plates are urged against the biasing force, and a cam provided on the lower end of the lower operation plate drives the movable clamping jaw into the fixed jaw to clamp the seatbelt therebetween.
