Abstract
Abstract A self-supporting table infant chair includes back, seat, and sidewall portions integrally formed from thermoplastic resin material by means of injection molding techniques so as to form a one-piece bucket-type chair. An upper set of laterally spaced support arms are secured within armrest portions of the chair, and a lower support arm is centrally secured within the seat portion of the chair. The upper set of arms cooperate with the lower arm so as to define a horizontal channel therebetween within which a projection portion of a dining table is to be disposed and from which the chair will be supported by means of the support arms. The proximal ends of the support arms are crimped so as to define laterally extending, flattened ears which then become embedded within the molded armrest and seat portions of the chair whereby translational and rotational movement of the support arms, along and about three mutually orthogonal axes, respectively, is positively prevented.
