Abstract: A variable length crank arm in a windshield wiper system provides a depressed park position for an associated wiper blade when the direction of rotation of a drive motor is reversed. The crank arm relies on an eccentric driver to vary its length and between a first length a longer second length. When the eccentric driver is rotated in a first direction to wipe the windshield, a spring loaded pin keeps the eccentric driver rotatably fixed to an output arm with the crank arm consequently at the first length. The spring loaded pin also engages a cam slot in a cam plate, the cam plate rotating freely with the output arm and the eccentric driver in the first direction. To move the blade to the depressed park position, the direction of rotation of the drive motor is reversed. This causes the cam plate to become rotatably stopped, with the now stationary cam slot forcing the pin out of engagement with the output arm.

Abstract: The operation device of a transmission in accordance with the present invention has a lock mechanism which can lock a shift rod in either a high speed range or a low speed range in a transfer in response to a detection signal when a control lever is positioned at a parking range, and has also alarm means for raising an alarm in response to a detection signal when the transfer is at a neutral position. When a vehicle is parked with the control lever being in the parking range, a driver can recognize the state of the transfer by the alarm if the transfer is at the neutral position, and shifts the shift rod to the high or low speed range by operating the transfer lever. The lock mechanism operates in the high or low speed range and a full driving system is connected so that the vehicle can be kept stopped and self-run of the vehicle on a slope or the like can be prevented.

Abstract: A starter motor construction including a drive shaft and a spline having an external helical thread is disposed concentrically of the shaft and rotates therewith. An internally threaded pinion is engaged with the spline and moves axially outward on rotation of the drive shaft against the force of a biasing spring to effect engagement of the pinion with a ring gear on the flywheel of the engine. A cushioning mechanism is incorporated between the drive shaft and the spline and includes a pair of metal plates, one of which is secured to the drive shaft and the other to the spline. A resilient disc composed of a rubber-like material is bonded to the opposed faces of the plates and is provided with a continuous peripheral groove. The cushioning mechanism acts to absorb radial torque and axial force as the pinion is moved into engagement with the ring gear.

Abstract: A shifting arrangement of an automatic transmision of a motor vehicle has a selector lever which can be pivoted in two shifting paths. In the first shifting path of the selector lever, various operating positions and automatically shifting gears of the transmission may be selected via a transmitting device. The selector lever can be changed over into a second shifting path in which, by a one-time pivoting of the selector lever from a center position, an upshifting or return shifting may take place by one gear respectively. A locking device interacts with the transmitting device so that the transmitting device, from which the selector lever is separated in the second shifting path, is held in its intended position.
