ABSTRACT:
BACKGROUND
A conventional child seat includes a harness which is releasably securable around the child with the harness passing over the child's shoulders and having a front end releasably locked with a buckle or similar fastening device. The harness passes over the child's shoulders and through the seat and has an opposite end frictionally engaged by a web adjuster mounted to the seat. Conventional web adjusters have a pivotally mounted cam member which may be released to facilitate sizing of the harness relative to the child. Examples of conventional web adjusters incorporating pivotally mounted cams with gripping surfaces for holding webs are shown in U.S. Pat. Nos. 3,434,186 (Rennert) and 3,872,550 (Yang).
SUMMARY OF THE INVENTION
The present invention is drawn to a web adjuster for securing straps, webs, or belts. The web adjuster can lock a web used for adjusting a harness for a child seat. The adjuster can limit longitudinal movement of an elongated web with respect to a base. The web adjuster includes a mounting plate, a sliding plate, and at least one resilient element biasing the sliding plate with respect to the mounting plate. The mounting plate, which is fixed to the base, includes first and second major faces generally lying in parallel spaced planes and a bridge rising above the second major face. The mounting plate is penetrated by a first aperture. The sliding plate, which is displaceable in shear with respect to the mounting plate, includes first and second major surfaces generally lying in a parallel spaced planes that are also parallel to the first and second major faces of the mounting plate. The sliding plate also includes at least one finger retaining the sliding plate with respect to the mounting plate, a plateau rising above the first major surface, and a neck extending transversely under the bridge. Each finger confronts and slidingly engages the first major face of the mounting plate. The sliding plate is penetrated by a second aperture.
The present invention is also drawn to a child seat having a harness and including the web adjuster.
