A collapsible child seat assembly for a shopping cart has a plastic seat panel and a plastic leg opening cover, both of which are pivotally mounted on a horizontal hinge wire that itself is fixedly mounted on a swingable rear gate of the cart. The forward edge of the seat panel is slidably mounted to a seat back pivotally attached to the rear gate. The rear edges of the seat panel and leg opening cover have interdigitated hinge extensions forming slots that accept therein the horizontal hinge wire for pivotal motion thereon. The hinge wire has protuberances corresponding to the locations of the hinge extensions of the leg opening cover. These protuberances cooperate with cantilevered leaf springs extending into the slots of the hinge extensions of the leg opening cover to frictionally retain the leg opening cover in its upright position covering the leg openings until it is manually folded against the seat panel. When the seat back is folded against the rear gate, the leg opening cover can remain stationary in the covering position. As a result, when the seat back is swung back open for the storage of merchandise in the seating compartment, the leg opening cover is already in its upright position covering the leg openings. This avoids the problem of merchandise falling from the cart as a result of shoppers forgetting to pivot the leg opening cover to the upright position before placing items in the seating compartment. |
