Abstract
A muscle-powered drive mechanism for vehicles or other equipment with at least one drive component, the drive movement of which is adapted to be transmitted to a drive shaft using a movement transmission system. By means of the mechanism, a user can selectively exercise a variety of muscles in the arms, legs or other parts of the body (e.g., back or abdominal regions), separately or together in many harmonious ways. For example, the system includes a set backrest drive mechanism whose drive movement is generated by a movement of a seat backrest relative to a seat surface independently of the movement of the seat surface. The system also includes a pair a freewheels mounted to a drive shaft. The movement of a mounted crank in either a forward or a rearward direction generations a single directional rotational movement of the shaft by means of one of the freewheels.
