Abstract
A power system is provided for extending and retracting a telescopic seating structure. The power system includes a frame, a drum operably mounted on the frame for rotational movement, and a plurality of slidably interconnected telescoping members having a terminal telescoping member operably attached to the telescopic seating structure. A cable is wound about the drum and the plurality of telescoping members. Upon rotation of the drum in a selected direction, a tensional force is exerted upon the telescoping members causing their selective extension or retraction to thereby extend or retract the telescoping seating structure. A control assembly is operably connected to the drum shaft to thereby deactivate the power mechanism when the telescopic seating structure is filly extracted or retracted. A cable guide assembly is positioned below the drum to thereby ensure that the cable is properly wound upon the drum during rotation to thereby assure maximum efficiency of the power system.
