Abstract
A safety interlock for an electric exercise treadmill having an electric powered tilt motor for varying the inclination of the exercise surface. The interlock protects the area below the treadmill frame when the treadmill is being used in an inclined position. Perimeter switches around the bottom of the frame are actuated by objects or body members moving under the frame to interrupt power to the treadmill and tilt motors. A safety restarting sequence assures the safety of the user.
