| 摘要 |
The invention relates to a power assisted adjustment system for assuming and maintaining a load member, and comprises a force-responsive means operably connected with an adjustment means, for assuming a load, and an actuable load-relieving means for temporarily reducing the load on the adjustment means. Application of force or torque to the force-responsive means actuates the load-relieving means thereby relieving load on the adjustment means, and substantially concomitantly operably effects a desired adjustment of the adjustment means.
