A seat with linkage attachable on either side of conventional luggage carts, on both sides, or to the backside, and once the push/pull handle rotates upward, positions itself vertical, for headroom clearance, and simultaneously deploys the seat to horizontal level, for seating, with an extension arm
A seat with linkage attachable on either side of conventional luggage carts, on both sides, or to the backside, and once the push/pull handle rotates upward, positions itself vertical, for headroom clearance, and simultaneously deploys the seat to horizontal level, for seating, with an extension arm attached to, or part of, the bent projecting arm of the push/pull handle. The seated user's weight transfers directly to the floor by a U-shaped underseat support, preventing the cart from moving, and when the handle is down, for cart movement, the downward rotation retracts the seat up to stowed position with a torsion spring. The seat can be installed on a corner post of the cart structure, manually rotated to level position around the cart's corner, providing seating at either side, or back of the cart, and in stow position rests against cart structure. In all embodiments multiple stacking of carts is allowed.

1. A folding seat attached to a luggage cart, comprising: a seat pivotally attached to structural support members that frame the luggage cart, said seat attached with interface hinge fittings that can be clamped, bolted, riveted or welded to the structural support members of the luggage cart, said seat, when pivoted to a stowed position, will stand upright against the frame of said cart and when pivoted to a deployed position will extend horizontally; a U-shaped support member attached at or near the center of the seat that can rotate from a supporting position depending perpendicular under said seat when said seat is in the deployed position, to a retracted position flat against the seat when the seat is in the stowed position; a pair of guide links that guide the U-shaped support member during rotation from the supporting position to the retracted position; a torsion spring at said interface hinge fittings biasing said seat to the stowed position; a linkage that rotates said seat from said stowed position to said deployed position, wherein said linkage comprises: a U-shaped push/pull handle having a cross bail and two legs, a pair of extension arms, each having two ends, attached to each leg of said push/pull handle at one of the ends, a pair of long connecting links, each with pivot joints at each end, wherein one end of each long connecting link is pivotally attached to the other end of the respective extension arm, and the other end of each of said long connecting link is pivotally attached to said seat; and wherein rotation of the push/pull handle from a horizontal position to a vertical position provides head room for a seat occupant, and automatically deploys said seat from said stowed position to said deployed position. 2. A folding seat for a luggage cart wherein said seat can be actuated from a vertical stowed position to a horizontal deployed position, wherein in the stowed position multiple carts can be nested in tandem; said seat is attached to a corner post of said luggage cart, and can be rotated around said corner post to a deployed position to the side or the rear of the luggage cart; a multiple hinge that at one end is rotatably clamped to and around said corner post, and at another end is attached to the center of the underside of said seat; a support fitting fixed to said multiple hinge, wherein said support fitting flanges out to support an underside of said seat, and contains a hinge to permit said seat to rotate vertically to said stowed position; and a torsion spring biases the seat to the stowed position, and wherein in the stowed position multiple carts can be nested in tandem.
