A multi-functional apparatus (43) employs a plurality of intermittent motion mechanisms. A single electromagnetic device selectively causes movement of intermittent motion mechanisms thereby moving mechanical devices coupled thereto. In a specific embodiment of the invention, the armature shaft (59) of an electric motor (51) rotates a worm gear segment (65) which then drives a helical gear (73) mounted in a gear housing (71). Via a series of pins, cams and gears, also mounted in the housing (71), this input can be made to drive selectively two or three intermittent rotary motion mechanisms (125,107,105) according to the rotary position of the helical gear (73). Mechanical devices which are coupled to the intermittent rotary motion mechanisms, e.g. a rear window wiper, a liftgate lock and a liftgate window release lock, are therefore operated according to the position range of oscillation or movement of the helical gear (73). In this way, the number of electromagnetic devices, or motors, required to be fitted a vehicle liftgate is reduced. <IMAGE> |
