Abstract: A windshield wiper drive mechanism having a hypocycloidal input and an oscillating crank output. A multiple component linkage is disposed between the input and output to convert the linear motion from the input to oscillating motion for the output. The linkage includes one member having a gear segment portion thereon, another member having an abutment surface thereon and a lost motion connection between the members. A parking mechanism including a gear rack and a stop member is operable, during parking of the wipers, to engage the gear segment and the abutment surface respectively thereby enforcing relative rotation between the members, as permitted by the lost motion connection, so that the output is oscillated through an extended arc to facilitate depressed parking of the wipers.
