Abstract: A rowing simulator which provides an oarsman with realistic resistance, motion, and feel. A curved frame supports and guides a freely sliding seat and a freely sliding energy dissipation unit. An oarsman, positioned on the seat, places his or her feet on a footrest that is part of the energy dissipating unit and pulls on a handle that simulates an oar. A chain connected to the handle causes a geared, resistance-producing flywheel to spin and a take-up device, having a series of pulleys and an elastic element, controls chain tension. During exercise, the independent seat and energy dissipating unit move apart and then together in a coordinated manner as a function of the stroke cycle of the oarsman. The curvature of the frame allows gravity to keep the oarsman in a central portion of the frame.

Abstract: An exercise device for people with lower body paralysis. The exercise device guides and resists the motion of the hands and feet away from and towards the trunk. The exercise device holds the feet at a nearly constant angle in relation to a line drawn between the ankles and hips. The arm motion is constantly mechanically linked to the leg motion so that voluntary arm motion causes motion of paralyzed legs. A knee guide keeps paralyzed legs in proper alignment. Arm motion controls the application of electrical stimulation to leg muscles. Electrical stimulation of leg muscles causes the generation of leg forces that contribute to the overcoming of the resistance to the movement of the hands and feet in relation to the trunk.

Each of the levers has a lower end adapted to support at least one removable weight and a handle at an upper end adapted to be grasped by an exerciser supported on the seat. During the performance of a rowing exercise, the exerciser pulls the handles upwardly and rearwardly to pivot the levers against the weight resistances held by the lower ends. The levers move along two outer vertical planes that converge with respect to the forward direction of the seat, and each of the levers pivots independently with respect to the frame.

Each set of travellers is selectively coupled to the endless chain.

Abstract: A seat (12) for an exercise apparatus is disclosed. The seat (12) includes a seat member (40), a back member (60), and a pair of wing members (67) that form an integral part of the back member (60).

The back member (60), including an pair of wing members (67), is designed to deflect backward during the drive portion of the rowing motion. The pair of wing members (67) are designed to additionally deflect in such a manner that they cup the rower's back during the drive portion of the rowing motion. A supportive insert (80), which extends into the seat member (40) and the back member (60), affects the flexibility of the back member (60) and the pair of wing members (67). The seat (12), including its foam exterior (90), is configured to maximize the comfort of the rower.

Abstract: Disclosed is an exercise device providing mechanical actions for independent or simultaneous exercise of the upper and lower body of a human user. Each action incorporates a mechanical movement converting output of the user to rotational motion and thereby powering one of two electrical generators. An exercise controller selects loads to be applied to the generators. The loads are coupled by the mechanical movements back to the user to provide resistance to the exercise effort. The exercise controller drives an electronic display which informs the user of his or her intensity of effort as well as the proportion of that effort being met through exercise of the upper body and the part being met through exercise of the lower body.

Abstract: Methods and apparatus for determining the effective force generated by an athlete acting upon a rowing apparatus are disclosed. A flexural member attached to the rowing apparatus and a footboard hingably attached to the flexural member at its upper end and slidably attached to the rowing apparatus at its lower end are provided. The flexural member is fitted with strain gauges which produce a signal indicative of the strain in the flexural member, this signal can then be converted to a measure of the effective force applied to the oars. Most preferably, apparatus of the present invention substantially eliminates the effects of residual torque friction, thermal deformation and the like by isolating the flexural member from which strain data is taken.
