Abstract
Belt adjusting apparatus for use on an infant or toddler seat is disclosed which comprises an interlocking assembly of geometrically-configured metal plates, each having at least one slot therein, with a belt passing through the slots in a specific path so that the belt is freely moved in one direction when in a locked position so as to tighten said belt, but cannot be moved in the other direction without manually adjusting the relative position of the metal plates. A spring return may be used to maintain the position of the plates in a locked position.
