摘要: An improved cable spool arrangement is disclosed for use in powered vehicle door operating systems, or in other cable-actuated devices, having one or more actuating cables. In one form of the invention, a groove, or other open channel-like opening, is formed along a generally helical path on the cable spool, and preferably has a varying groove depth along at least a portion of the helical path in order to take up or pay out at least a portion of a cable at a correspondingly varying rate with respect to cable spool rotation and thus cause movement of a door or other movable member at a correspondingly varying rate with respect to cable spool rotation. A second, constant depth portion of the helical groove can also be optionally provided for generally constant take-up or pay-out of a cable onto or from the constant-depth portion of the helical groove.
