Title: Non friction direct drive power system

Abstract: The present invention relates to a power system for extending and retracting a telescopic row seating system, comprising a drum operably anchored to a drum frame, wherein a drum has at least two drum shafts rotatably engaged thereto. Further, it includes a plurality of interconnected drive carriages adapted for connection to a telescopic seating system to extend and retract the telescopic seating system, drive carriages being configured to selectively mateably wind onto and off from the drum as the drum is rotated. The power mechanism comprises a motor, a motor frame, at least two motor shafts extending from each side of the motor. The drive shaft is connected by the plurality of coupling means, a drum shaft one side and a motor shaft on the other providing motion to rotate the drum. The drip means enables the drum to rotate and thereby extend and retract the drive carriages so that an extended portion of the drive carriages is substantially continuously tangentially aligned with a wound portion of the drive carriages on the drum.
