1. A web adjuster device comprising:
- a frame comprising a pair of spaced apart side walls, and a first web engaging surface extending transversely between the side walls;
a web clamping member movably mounted to the frame between the pair of side walls, the web clamping member defining a second web engaging surface and a third web engaging surface separate from the second web engaging surface;
wherein the frame is configured to receive a web extending between the side walls, at least partially around the web clamping member, and between the first and second web engaging surfaces and adjacent to or in contact with the third web engaging surface; and
wherein the third web engaging surface is configured to be responsive to a first direction of web travel through the web adjuster device to urge the second web engaging surface toward the first web engaging surface to trap the web therebetween.

Abstract
A web adjuster for use with a web. A clamping member and a bearing member are mounted to a web adjuster frame and movable relative to the frame about a common axis. The web extends at least partially around the bearing member. Applying tension to the web moves the clamping member toward a web stop on the frame to trap the web between the clamping member and the web stop.

19. A web adjuster device comprising:
-
a frame with a pair of spaced apart side walls and having a coupling portion and a web stop extending across the frame;
an elongate member mounted between the spaced apart side walls;
a bearing member movably mounted on the elongate member which extends through the bearing member, the bearing member having a longitudinal axis of rotation;
means for clamping movably mounted to the frame;
a web extending at least partially around each of the bearing member and the means for clamping and passing between the means for clamping and the web stop;
the web clamping member responsive to a first direction of travel of the web relative to the frame to urge the means for clamping toward the web stop to trap the web therebetween. - View Dependent Claims (20, 21)

22. A web adjuster device configured to clamp a web having a free end and a tension end when tension is applied to the tension end of the webbing, the adjuster device comprising:
-
a webbing guide;
a pin mounted to the webbing guide;
a web clamping member mounted by the pin to the webbing guide and movable with respect to the webbing guide;
a bearing member mounted by the pin to the webbing guide and movable with respect to the webbing guide, the bearing member extending radially beyond the web clamping member;
a coupling portion extending from the webbing guide;
a locking portion on the web clamping member which in a locked position clamps the webbing between the locking portion and the webbing guide to prevent movement of the webbing through the adjuster when tension is applied to the tension end;
a release actuator to cause movement of the webbing guide relative to the web clamping member to separate the webbing guide and the web clamping member wherein the webbing is released to allow it to move in either direction through the adjuster device; and
a projection on said web clamping member that abuts against the webbing between the locking portion and the tension end thereof so that the webbing when tensioned exerts a force against the projection which urges or causes rotation of the clamping element in a direction that holds or moves the locking portion in or into a locked position.
