ABSTRACT:
An apparatus for controlling the distance between a vehicle to which it is attached and a surface over which the the vehicle may be moving. The apparatus includes a cable and a sheet member which in a first mode is in contact with the surface but in a second mode is out of contact with the surface. Because of design, the sheet member induces a greater tension in the cable when in the second mode than when in the first mode; the increase in tension may be used to actuate a control or indicating devices on the vehicle to maintain the distance within desired limits.
