Abstract
A handle adjustment mechanism for an infant car seat includes a pair of symmetrically similar, axially aligned, hollow first cylinders positioned on each side of an infant carrier and at respective handle arms. The first cylinders have a common axis coextensive with the axis of rotation and formed with a circumferential slot adjacent to the lower ends of the arms of the carrier. A pair of reduced second cylinders integrally formed on the infant carrier on the opposite sides thereof are located within the first cylinders. The second cylinders have a common central axis coincident with the axis of rotation for rotation movement of the first cylinder and arms therearound. The exterior surface of each second cylinder are formed with a plurality of radial recesses. A pair of releasable locking mechanisms are provided, each locking mechanism including a plate with a pivot pin rotatably securing the plate interior of an associated arm, a finger extending downwardly through the slot and positionable into a preselected recess in the second cylinder, and a spring having opposes surfaces in contact between a surface of the plate and an adjacent wall of an arm. Each of the plates has an expose…
