ABSTRACT:
An improved infant carrier seat rocker is provided for a typical molded plastic type infant carrier seat embodying a rounded bottom to facilitate a fore and aft rocking motion. This type of seat is currently in production. The rocker is comprised of a housing from which a lifting member protrudes. A power unit is mounted within the housing. This power unit provides rotational energy. A drive means consisting of an eccentric mounted to the output of the drive unit and slidably connected to the lifting member to convert rotational energy to vertically reciprocating motion is employed to impart the vertical motion to the lifting member. The lifting member in turn imparts this motion to a suitable feature of the carrier seat, typically the lower edge of the seat, and the seat then rocks as the lifting member oscillates vertically.
