Paper outlines the design of a replacement for common single rider golf cart seats that safely positions a person with mid-level paralysis in an effective golfing stance. The prototype comprises a pivoting three piece seat with a dynamic torso support and harness designed to enable a golfer without back muscles to rotate the upper body through a golf swing. It consists of a bottom piece that is rigidly attached to a set of parallel links on each side. These links are connected to the back support at one end and to the foot support at the other. An electromechanical linear actuator is attached to the back support and moves the golfer from the seated position to a partially standing golf stance. The seat operates in two stages of motion: the range of motion between horizontally seated and 30 degrees tilted forward, and the seat motion between 30 and 70 degrees from the seated position. The linear actuator is controlled via a jog switch. For golfers without back muscles, a removable flexible spine support has been implemented into the design. This rod works with a chest harness in opposition to the abdominal muscles of the golfer and allows leaning forward and rotating the upper body to golf. The rod then returns the golfer’s torso to the upright seated or standing position after play. User testing verified that the sitting surface was capable of tilting forward from 0 to 70 degrees and determined a personal comfort range between 0 and 55 degrees. The adaptive golf cart seating was designed by engineering students at California state University, Chico and entered in the RESNA 2010 Student Design Competition.
