| Abstract: |
A multi-functional personnel restraint, particularly suited for use by workers in a substantially zero gravity environment comprises a stationary track defined by two rails which are spring biased to a minimum spacing position. The rails respectively carry a pair of parallel, opposed grooves on their inner surfaces. The grooves are engagable by cleats attached to the bottoms of the shoes of the person requiring restraint. The cleats are engagable with the grooves by a pivotal movement in a vertical plane, thus substantially balancing vertical forces imparted on the shoe or shoes during the groove insertion movement.

What is claimed and desired to be secured by Letters Patent is:
1. A restraining system especially suited for a low gravity environment comprising, in combination:
- an elongated base element having means thereon for securement in a desired location, said base element having parallel generally vertical side walls when the base element is horizontally disposed;
- a pair of parallel, restraining plates secured to said side walls and projecting above said base element;
- means for laterally shiftably mounting the top portion of at least one of said restraining plates relative to said base plate, whereby the lateral spacing of the upper portions of said restraining plates may be varied;
- resilient means urging said one restraining plate to a minimum lateral spacing position relative to the other restraining plate;
- said restraining plates respectively having longitudinal grooves in their inner surfaces disposed in opposed parallel relationship to define a restraining track;
- a restraint cleat attachable to the bottom of a shoe when worn by a person; and
- said restraint cleat defining a horizontal flange dimensioned to fit within said restraining track when said restraining plates are disposed in said minimum lateral spacing position and to pass between the top edges of said restraining plates when said one restraining plate is shifted laterally relative to said other restraining plate.
