Claim Text:
1. A treadmill body support system for gait training exercise of a user on a treadmill, the treadmill body support system comprising: a stationary support frame; a lateral displacement rotational means vertically oriented and rotationally connected about a vertical axis to the stationary support frame; a support lever extending between the lateral displacement rotational means and a front body support post, the support lever connected rotationally at a first support lever end to the front body support post and connected rotationally at a second support lever end to the lateral displacement rotational means; a front body support mounted on the front body support post by a swivel joint so that the front body support is configured to be tilted and adjustably positioned along the front body support post upward or downward, the front body support having a front planar surface; a seat having a front seat end and a back seat end for supporting the user, the seat mounted on a seat support extension connected to the front body support post and wherein the front seat end is positioned in a direction facing the front body support and the lateral displacement rotational means so that the seat positions the user to face the lateral displacement rotational means to enable the user's body freedom of a lateral gait movement when the stationary support frame is positioned over a treadmill surface and wherein the seat is configured to be adjustably positioned along the seat support extension closer toward or further away from the front body support and wherein the seat is adjustably tilted downward so that the user supported by the seat will be wedged between the seat and the front body support with the user's abdominal region in contact with the front body support; a position stabilizing arm positioned at an elevation higher than the support lever and parallel to the support lever, the position stabilizing arm extending between the front body support post and the lateral displacement rotational means and being rotationally connected at a first position stabilizing arm end to the front body support post and rotationally connected at a second position stabilizing arm end to the lateral displacement rotational means so that the seat and the front body support are maintained at a constant angle with respect to the treadmill surface as the position stabilizing arm and the support lever move rotationally about the lateral displacement rotational means and the front body support post for the lateral gait movement of the user; an adjustable body weight support spring means rotationally connected to the lateral displacement rotational means for applying an adjustable full or partial weight-bearing supporting force to the support lever so that the seat, the front body support and the user wedged between the seat and the front body is configured to move up or down and laterally responsive to a variable body force supplied by the user as the user walks, stands or sits over the treadmill surface in the treadmill body support system; and a control lever mounted on the adjustable body weight support spring means so that upon movement of the control lever an off-center circular disk is turned to a static mode position which releases a gas control pin to limit the movement of a pressurized gas within the adjustable body weight support spring means so that the movement of the seat and the front body support is configured to be locked at variable fixed elevations including a treadmill body support sitting height position to allow the user to enter or exit the treadmill body support system from a wheelchair sitting position and hold the seat, the front body support and the user in a continuous treadmill body support sitting position without the application of the user's body weight force or an external force and so that upon further movement of the control lever the off-center circular disk is turned to a dynamic mode position to activate the gas control pin to release the movement of the pressurized gas within the adjustable body weight support spring means so that the seat, the front body support and the user are not restrained to the treadmill body support sitting height position or a treadmill body support fixed elevational position and is configured to move to a treadmill body support standing or a treadmill body support walking position on the treadmill surface with the user supported by the adjustable full or partial weight-bearing supporting force applied by the adjustable body weight support spring means to allow the user's body freedom of a vertical gait movement.
