The clutch includes a probe mounted on the base of a handle mechanism assembly in line with the handle, and a pawl pivotally mounted in the handle and disposed to engage a lug splined to the handle shaft and torsionally coupled to the latch. When the handle is in its "home" or "closed" position, the probe engages a roller on the end of an arm connected to the pawl and rotates the pawl away from the lug so that the handle shaft will not backdrive the handle into the passenger space when the exterior latch handle is operated to unlatch the door. When the handle is moved away from the probe, the pawl engages the lug to establish two-way torsional coupling between the handle and the latch.

Abstract: A one-way clutch apparatus comprising a driving member having a plurality of recesses, a corresponding plurality of biasing members disposed in the recess, a corresponding number of keys or struts disposed over the biasing members in the recesses, and a driven member having a plurality of key-engaging notches formed circumferentially about an inside surface. Each of the keys includes a pair of laterally protruding arm portions and each of the arm portions has a ramp formed thereon which acts as a relief to allow the inside surface of the driven member to be placed to close proximate relationship with the inside surface of a driving member and to overlay portions of the recess.
