Tongue assembly
First Claim
1. A tongue assembly for use in a safety apparatus in which belt webbing restrains movement of an occupant of a vehicle, said tongue assembly comprising:
- a base having a latching portion for engagement with a buckle, a first clamping surface engageable by the belt webbing, and an opening through which the belt webbing extends;
a cover mounted on said base, said cover having an actuator portion engaged by the belt webbing upon tensioning of the belt webbing to move said cover on said base between a first position and a second position; and
a clamping member mounted on said base, said clamping member having a second clamping surface disposed adjacent said first clamping surface on said base, the belt webbing passing between said first clamping surface on said base and said second clamping surface on said clamping member;
said clamping member being movable into a clamping position in which said second clamping surface on said clamping member clamps the belt webbing against said first clamping surface to block movement of the belt webbing through the tongue assembly in a first direction;
said cover having means for moving said clamping member into its clamping position to clamp the belt webbing when said cover moves from its first position to its second position.

Abstract
A tongue assembly for use in a safety apparatus in which belt webbing restrains movement of an occupant of a vehicle includes a base, a cover, and a cam. The cover is mounted for sliding movement on the base. The cover has an actuator portion engageable by the belt webbing to slide the cover along the base between a first portion and a second position. The cover engages and pivots a cam when the cover slides from its first position to its second position. The cam has a clamping surface disposed adjacent a clamping surface on the base. A portion of the belt webbing passes between the clamping surfaces on the base and the cam member. The cam is pivoted by sliding movement of the base into a clamping position in which the cam clamps the belt webbing against the base to block movement of the belt webbing through the tongue assembly.

7. A tongue assembly for use in a safety apparatus in which belt webbing restrains movement of an occupant of a vehicle, said tongue assembly comprising:
-
a base having a latching portion for engagement with a buckle, a first clamping surface engageable by the belt webbing, and an opening through which the belt webbing extends; a movable member mounted on said base said movable member having actuator means engageable by a first portion of the belt webbing for moving said movable member on said base between a first position and a second position; and a clamping member mounted on said base, said clamping member having a second clamping surface disposed adjacent said first clamping surface on said base, a second portion of the belt webbing passing between said first clamping surface on said base and said second clamping surface on said clamping member; said clamping member being movable into a clamping position in which said second clamping surface on said clamping member clamps the second portion of the belt webbing against said first clamping surface at a location spaced from said opening to block movement of the belt webbing through the tongue assembly in a first direction; and said movable member having means for moving said clamping member into its clamping position when said movable member moves from its first position to its second position. - View Dependent Claims (8, 9, 10, 11)

12. A tongue assembly for use in a safety apparatus in which belt webbing restrains movement of an occupant of a vehicle, said tongue assembly comprising:
-
a base having a latching portion for engagement with a buckle, a first clamping surface engageable by the belt webbing, and a webbing opening disposed intermediate said latching portion and said first clamping surface, a first portion of the belt webbing extending through said webbing opening; a cover mounted on said base, said cover having an actuator portion disposed at least partially in said webbing opening in said base and engageable by the first portion of the belt webbing to slide said cover along said base between a first position and a second position; and a cam mounted on said base, said cam having a second clamping surface disposed adjacent said first clamping surface on said base, a second portion of the belt webbing passing between said first clamping surface on said base and said second clamping surface on said cam; said cam being pivotable between a first position and a second position in which said second clamping surface on said cam clamps the second portion of the belt webbing against said first clamping surface to block movement of the belt webbing through the tongue assembly in a first direction; said cover having a surface for engaging said cam when said cover slides from its first position to its second position; said actuator portion of said cover being movable by the first portion of the belt webbing to slide said cover from its first position to its second position to pivot said cam from its first position to its second position to clamp the belt webbing. - View Dependent Claims (13, 14, 15)
