A resiliently biased seat panel for a seat frame associated with an end gate of a push-cart. The end gate has leg holes to permit the legs of a child seated on the seat frame to extend therethrough. The seat panel comprises a hinge along an edge thereof to hingedly retain the panel for displacement to and away from the seat frame. A spring biases the seat panel away from the seat frame in a position against the leg holes to obstruct at least a substantial portion of the leg holes when the seat panel is not utilized for seating a child. Thus, articles positioned on the seat frame cannot fall through the leg holes as it is obstructed by the seat panel.

A resiliently biased seat panel for a seat frame associated with an end gate of a push-cart, said end gate having leg holes, said panel comprising hinge means to hingedly retain said panel for displacement to and away from said seat frame, spring means biasing said seat panel away from said seat frame in position against said leg holes to obstruct at least a substantial portion of said leg holes, said spring means having a spring biased displaceable portion engaged by said seat panel and displaceable towards the plane of said seat frame when continuous pressure is applied and maintained against said displaceable portion by a sustained load on a seating surface of said seat panel and exceeding the spring restoring force of said displaceable portion, said panel automatically returning to its position against said leg holes when said sustained load is removed, an attachable portion immovably being secured with respect to said displaceable portion, said spring means being a coil spring formed of metal spring wire, said coil spring having a helically wound portion between said displaceable portion and said attachable portion, said displaceable portion being a U-shaped end portion of said metal spring wire extending in a plane tangent to the circumference of said helically wound portion, said attachable portion being formed in an opposed end portion of said metal spring wire.
