<p>A window regulator assembly comprising a window panel (12), a track (18), a slider member (17), a slider moving assembly (21), including a drive assembly (20) and a coupling assembly (23). The coupling assembly (23) of the slider moving assembly (21) is constructed and arranged to couple an output movement of the drive assembly (20) to the slider member (17). The drive assembly (20) includes a drivable input structure (112) and a driven output structure (114), which structures are rotatable about a common axis. The drive assembly includes roller (128) and spring (130) members disposed within a housing (126) and constructed and arranged to prevent movement of the output structure (114) upon predetermined external force being applied thereto via the coupling assembly (23). The output structure (114) has ramp surfaces (149) each converging toward the housing (126). Each of the ramp surfaces (149) frictionally engages an associated one of the rollers (128), the rollers (128) being biased by the spring members (130) in a converging surface direction towards the converging surfaces between the ramp surfaces (149) and the housing (126). The wedging relation of the rollers (128) between the ramp surfaces (149) and the housing (126) prevents movement of the output structure (114) upon application of the predetermined external force being applied thereto. The input structure (112) is rotatable to engage the rollers (128) upon application of the external driving force and thereby move the rollers (128) against the bias of the spring members (130) and away from the converging surface direction, so that continued driven movement of the input structure (112) is received by the output structure (114) so that the output structure (114) is thereby driven to move the slider member (17) and thus the window panel (12) via the coupling assembly (23).</p> |
