Abstract: A removable seat assembly for mounting on an all-terrain vehicle, which seat assembly is characterized by a base plate frame for mounting on an ATV and receiving a fixed or rotatable pedestal or a pedestal having a rotatable pedestal flange, and a seat attached to the pedestal or the pedestal flange. The base plate frame is designed to permanently or removably weld, clamp or bolt on the utility rack of an all-terrain vehicle or mount on a seat slide, and a swivel mechanism may be interposed between the seat pedestal and the seat or between the seat pedestal and the base plate frame or seat slide to facilitate rotation of the seat with respect to the base plate frame and the all-terrain vehicle. In another embodiment a pair of support arms extend upwardly from a support arm mount secured to the rotatable seat, pedestal or pedestal flange and terminate in a top frame carrying a cover to protect and camouflage the occupant of the seat.

Abstract: A braking mechanism to control rotational movement of a seat is disclosed. The braking mechanism may comprise a circular member (e.g., a disc or ring) that is coupled to a base assembly and a caliper, coupled to a seat assembly, to engage the circular member. In a biased position, a braking element of the caliper applies a braking force to the circular member. A user can reduce the braking force by increasing the tension on a cable coupled to the caliper. Once the braking force is sufficiently reduced, the user may rotate the seat until the desired rotational orientation is attained. Upon release of the cable, the braking mechanism re-engages to prevent further rotational movement.

Abstract: 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.
