ABSTRACT:
A child's seat comprising a plastic seat panel and a plastic leg opening cover both of which are pivotally mounted at their rear edges on a transverse support wire, that itself is slidably mounted upon the cart rear frame. The forward edge of the seat panel has a plurality of curved flanges that engage a support wire mounted on the seat back frame. Interaction between the flanges, the wire, and the edges of a recess in the seat back frame adjacent to the wire holds the components interlocked, while allowing the pivot movement of the seat panel with respect to the seat back frame. A reinforced plastic seat back frame has two leg portions each terminating at its bottom in an S-shaped portion that fits into an opening in the cart rear panel to support the seat back frame and allow pivotal movement thereof. The plastic seat back frame is reinforced by a pattern of integrally molded ribs. Additional reinforcement is obtained by utilizing metal inserts placed in channels between adjacent ribs. The rear side of the seat back contains a molded recess section in which advertising material can be placed. The material is protected by a plastic window which snaps into a locked position in the recess section.
