A safety harness on/off switch assembly for a motorized treadmill comprises a support positioned over the treadmill, and a safety harness including a pair of spaced laterally interconnected straps at their upper ends yieldably and flexibly suspended from the support and at their lower ends including a pair of loops to receive portions of the body of a user upon the treadmill. A normally closed safety switch is mounted upon the support and is located in the electrical circuit of the treadmill. When the user faints, falls, or trips, or is injured, his or her body rests upon the straps and opens the safety switch thereby automatically shutting down the motorized treadmill. |

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION Referring to the drawings, FIGS.
1 through 10, a motorized treadmill assembly is generally indicated at 11, FIG.
1, including a frame or base 13 and a power driven endless belt 15 located between a pair of opposed spaced side rails 17.
Belt 15 is in the form of a continuous loop which is driven by a variable speed electric motor 19, FIG.
2, 3 and 7.
Drive roller 21 is connected to the motor 19 and supports one end of the belt 15.
Idler roller 23 supports the opposite end of the belt 15, with both rollers 21 and 23 being journaled upon the frame 13 and between the side rails 17.
The present frame or base 13 includes the upright pedestal 125 at the forward end thereof within which is housed the electric motor 19.
Across the rear face of an upper portion of the pedestal 25 is a U shaped handle 27 for providing assistance to the user, such as shown in FIGS.
2 and 3.
Power conduit 29 is connected to motor 19 and at one end has a male socket 31 connectible to the female power socket 113, FIG.
1.
An overhead support means is generally indicated at 33, FIG.
1, normally spaced above treadmill 11, and in the illustrative embodiment includes the elongated tubular support 35 which is suitable secured to ceiling 37, FIGS.
2 and 3.
A pair of longitudinally spaced extension arms 39 depend from support 35.
A pair of transverse harness support bolts 41 extend across the extension arms 39 and are secured thereto by nuts 43.
The safety harness, generally designated at 45, includes a pair of laterally spaced straps 47, made of a suitable fabric similar to seat belt material.
Each strap includes an upper strap portion 49 and a lower strap portion 51.
Each strap upper portion 49 terminates in the loop 53 which extends over a portion of S hook 55 which is located within extension arm 39.
The upper portion of S hook 55 extends over and is supported upon the transverse harness support bolt 51, FIGS.
4 and 5.
The strap upper portion 49 includes the adjustable female seat belt or locking member 57 providing a means for shortening or lengthening upper portion 49 in a conventional manner
