Abstract

A differential motion machine for closely simulating natural human motion is provided. A user mountable carriage is designed to slide freely, in the fore and aft directions. The carriage contains a power transfer element, such as pedals, arm levers or the like, which convert the user's motions into a means for propelling the carriage relative to a dynamic element. A dynamic element generally consists of an endless belt or the like driven by a motor or by a slight incline to a base frame which engages the power transfer element. Additionally, a force element causes a force against the carriage preferable relative to the dynamic element. This force to the carriage simulates the drag and other resistances encountered in nature.

Claims (6)

1 - 31 . (canceled)

32 . A human motion device, comprising:

a frame having a front end and a rear end;

a carriage supported on said frame and adapted to user engagement, said carriage further adapted for generally reciprocating movement between said ends;

a dynamic element capable of movement in a first direction, and further capable of providing a force against said carriage thereby urging said carriage in said first direction; and

wherein said carriage further comprises foot pedals enabling the user to propel said carriage in a second direction.
