  • Patent number: 5547205
    Abstract: A wheeled luggage cart comprising a folding seat and a handle that, through a simple rotation by the user, releases said seat and rotates it down from a folded up compact stowed position to a horizontal level position for seating the traveler. The seat is attached to the cart by means of a hinge assembly that engages the vertical posts of the cart and permits rotation of the seat to the two positions; in the deployed seating position, dual legs extend downward from the center of the seat to the floor to support the user's weight. To position these legs correctly, a connection guide link, attached to the luggage cart, guides the legs to their correct load bearing position. In addition to support this load, there is a diagonal compression link attached to the seat, and attached to the base of the luggage cart, to provide a truss structure to share the imposed weight. A sliding bracket on the cart allows the diagonal link to be compactly stowed with the seat flatly against the back of the cart.
