<p>A collapsible seat pivotally secured to an end gate of a nestable shopping cart. The seat has a seating surface and is slidingly attached to a collapsible secondary gate which is hinged to the end gate and which provides a back rest for the seat. The improvement in the collapsible seat structure comprises the seat having opposed side end members pivotally secured at one end to the end gate and each having a free inwardly facing hook end. The side end members extend substantially parallel to one another. A connecting rod is secured to each of the side end members and extends adjacent to the hook ends to define an open ended guide channel between the hook end and the connecting rod. The secondary gate has opposed side end edges received in a respective guide channel. Each guide channel is restricted for sliding displacement along its respective end edge in the area of the back rest. Each hook end lies behind an outer surface of the back rest when the secondary gate is collapsed in the direction of the end gate.</p> |
