BGD&R 23727B ABSTRACT A belt clamp for use in a vehicle passenger restraint belt system comprises a pair of jaws, one of which is movable relative to the other, such as by a lever, is normally held away from the other by a spring, and is moved toward the other in response to an abnormally high pull-out force on the belt to engage a restraint belt guided between the jaws. A multiplicity of spaced-apart, elongated straight teeth oriented widthwise of the belt and of uniform, smoothly curved cross section frictionally clamp the belt against pulling out by tucking loops of the belt into complementary recesses in the other jaw. Preferably, both jaws have substantially identical teeth and substantially identical recesses which are generally complementary to the teeth, the shapes of the teeth and recesses being such as to produce a smoothly corrugated clamping section in which several loops of the belt are formed and by which frictional holding forces are developed without any cutting or abrading of the belt. Advantageously, small variations in gripping faces of the jaws compensate for variations in the properties of the belt (e.g., thickness, density and elasticity) and for deformation of the jaws.
