INTERMITTENT ROTARY MOTION MECHANISM FOR USE IN AN AUTOMOTIVE VEHICLE

摘要

An intermittent rotary motion mechanism for use in an automotive vehicle includes an electromagnetic device (71), a member (73) moving in response to selective energization of the electromagnetic device (71), an intermittent motion mechanism (75) and a window wiper shaft (81) coupled to the intermittent motion mechanism (75). The intermittent motion mechanism (75) moves the wiper shaft (81) in a first wiping positional range when the electromagnetic device (71) moves the member (73) a first predetermined amount. The intermittent motion mechanism (75) further moves the wiper shaft (81) to a park position when the electromagnetic device (71) moves the member (73) a second predetermined amount in a first direction. The wiper shaft (81) is mechanically deterred from movement from the park position concurrently with the electromagnetic device (71) further moving the member (73) past the second predetermined amount in the first direction.
