ABSTRACT:
An infant carrier and base are provided with locking features which include a spring-mounted bolt protruding laterally from the base and a hollow or aperture in the carrier which engages the bolt when the carrier is inserted into the base. The upper surface of the bolt is sloped so that the carrier forces the bolt inward (to a retracted position) as the rim of the aperture slides over the protruding end of the bolt. A spring snaps the bolt back into place once the carrier is fully inserted and the aperture is aligned with the bolt. The carrier contains a lever arm whose fulcrum is positioned adjacent to the aperture. A spiral cam protrudes from the fulcrum to engage a knob extending upward from the side of the bolt, so that when the lever arm is rotated the cam urges the knob backward, retracting the bolt and permitting removal of the carrier from the base.
