A seat belt assembly including a seat belt webbing, a buckle, and a connector tongue assembly. The tongue assembly includes a body, a slot in the body for receiving a seat belt webbing, a locking mechanism located proximate the slot, and a spring biasing the locking mechanism towards the slot to frictionally engage the webbing to prevent freefall of the assembly.

A buckle having an adjustable loop end forming a primary plane with opposing side walls. The adjustable loop end has a central bar positioned between a first strap opening and a second strap opening. A pair of slots operable to receive the terminal ends of the central bar are recessed into the interior surface of the opposing side walls with the bottom edges of the slots being longer than the top edges. A pair of tabs on opposite ends of the central bar extend outward from the central bar along a longitudinal axis of the primary plane and towards the second strap or belt opening. Optionally, a protrusion extends from a lower surface of the fixed loop end wherein the protrusion is positioned at a right angle with respect to a vertical axis of the primary plane.

A locking tongue for a seat belt has a deflecting portion for a webbing. The deflecting portion includes a webbing passage and a clamping element. The clamping element is displaceable between a home position in which the webbing is freely movable and a blocking position in which the clamping element is displaced against a wall of the webbing passage so that the webbing is clamped between the clamping element and the wall of the webbing passage. The clamping element includes a clamping surface which in the blocking position clamps the webbing against the wall of the webbing passage. The clamping element is guided along a curved guide path extending in an area of the blocking position substantially perpendicularly to the wall so that in the blocking position the clamping element is moved against the wall substantially perpendicularly with the clamping surface.
