Abstract: A powered rocking base for a typical molded plastic infant car seat to allow the infant car seat to attach to the rocking base and facilitate a rocking motion of the base and infant car seat. The rocking base attaches to typical molded plastic infant car seats currently in production. The rocking base provides side-mounted friction knobs that allow for secure attachment of a typical molded plastic infant car seat. A power unit is mounted within a housing on the underside of the rocking base. The rocking motion is provided by a mechanical rotating weight inside the housing that is weighted eccentrically and rotates in a horizontal plane, creating a fore and aft rocking motion.
