With Flexible Shaft Coupling Permitting Limited Relative Rotation Patents (Class 192/55.2)
  • Patent number: 8985296
    Abstract: A clutch unit includes lever-side clutch portion for controlling transmission and interruption of rotational torque to an output side through lever operation and a brake-side clutch portion for transmitting torque input from the lever-side clutch portion to the output side and for interrupting torque reversely input from the output side. The lever-side clutch portion has an outer centering spring provided between a lever-side outer ring to be rotated through the lever operation and a cover restricted in rotation, for accumulating an elastic force obtained by torque input from the lever-side outer ring and for restoring the lever-side outer ring to a neutral state with the accumulated elastic force through releasing of the torque input from the input-side member. The outer centering spring has a band plate-like spring member having a C-shape.

  • Patent number: 6449798
    Abstract: A multi-function apparatus for controlling various functions of a liftgate of an automotive vehicle. The apparatus includes an elastomeric member which is operably disposed in connection with a gear which imparts a driving force to a drive shaft of a window wiper member. The elastomeric member, in one embodiment, is a coiled spring which allows movement between the drive shaft and the gear driving the drive shaft in the event the wiper becomes frozen to the window of the vehicle or otherwise immovable. In this manner various other functions can be carried out by the apparatus regardless if the wiper becomes temporarily immobilized.
