Abstract: A wheeled chair for transporting patients includes a plurality of footrests for supporting a patient's feet thereon. Each footrest is pivotable between an up position and a down position, and includes a biasing mechanism for biasing the footrest toward the up position, or the down position, or whichever of the two positions the footrest is currently closer to.

Abstract: A wheeled chair for transporting patients includes a frame, a seat, a plurality of wheels, and a plurality of armrests. The armrests are pivotable about a common pivot axis that is oriented generally horizontally and that is positioned underneath the seat and forward of a back support. Each armrest may include a locking mechanism for holding the armrests in a use position. When locked in the use position, a user may apply an upward force on the armrests to lift the chair upwardly that does not cause pivoting of the armrests. The chair is designed to allow nesting with other chairs of similar design. The front wheels may be positioned laterally apart a greater distance than the rear wheels to allow a first chair to nestingly receive a rear portion of a second chair. Foley hooks may also be included on the chair for hanging a Foley catheter bag.

Abstract: An all terrain vehicle is disclosed having a frame and ground engaging members supporting the frame. A driver's seat is supported by the frame, and extends along a first longitudinal axis. A passenger's seat is supported by the frame and extends along a second longitudinal axis, where the first and second longitudinal axes are laterally spaced apart. The passenger seat may also be movable to a second location to allow for the vehicle to support a gurney, which extends in a front to back orientation.
