Abstract: A power actuator for a door lock device comprising an electric motor driving a worm gear, a gear wheel driven by the worm gear, a handling lever driven by an arcuate projection on the gear wheel and a locking arm rotated by the handling lever. The wheel gear has a peripheral groove with a portion of reduced width for supporting opposite ends of an elongate coil spring; which is compressed in a direction corresponding to the rotation of the gear wheel. An arcuate segment projects axially from the gear wheel. The opposite ends of the arcuate segment and the handling lever is shaped to provide point contact with the handling lever upon initial engagement and surface contact as the arcuate projection moves the handling lever to the locking and unlocking position. A contact is disposed on a base plate; and contacts on the handling lever slidably engage the contacts on the base plate to detect the locking and unlocking position of the handling lever.

Abstract: A windshield wiper includes a first pin connected to a drive mechanism, a primary lever supported by the first pin, a second pin mounted to the primary pin, a wiper arm fixedly mounted to the second pin, the primary lever being rotated about the second pin by the drive mechanism to cause reciprocating motion of the wiper arm in an arcuate path, a first cam member rotatable about the first pin, a second cam member rotatable about the second pin, and a secondary lever for connecting the first cam member and the second cam member together. The second cam member is so rotated as to allow a center of the first cam member to move relative to a center of the first pin, thereby changing the effective length of the primary lever such that the arcuate path of the wiper arm is changed. A wheel gear is used to rotate the second cam member through a predetermined angle. The second cam member is rotatably supported by a stationary member. A gear portion is meshed with the wheel gear and rotated by the motor.

Abstract: A vehicle windshield wiper structure has a wiper arm connected to a wiper head and supports a wiper blade which is adapted to be forced onto the surface of the windshield glass. A spring is provided to force the wiper blade into engagement with the windshield glass surface. The spring is engaged at one end with an intermediate portion of the wiper arm and at the other end with an end of a swingable lever which is pivotably mounted on the wiper head. The other end of the swingable lever is provided with a cam follower roller which is adapted to be engaged under a resilient force applied by the spring with a cam provided on a stationary part of the vehicle. The cam has a profile which is slanted at the opposite end portions so that the resilient force depressing the wiper blade into engagement with the windshield glass surface is decreased at each end of the stroke of movement of the wiper to thereby decrease the noise which may otherwise be produced when the wiper movement is inverted.

Abstract: In a door-locking device, an output lever is connected to a release member and other operating mechanisms in order to eliminate a locking lever and a locking link. The elimination of these members decreases the number of connecting portions between members or mechanisms, thereby decreasing loose fittings therebetween. Thus, the generation of noise is lowered resulting in the realization of quietude. Also, the sense of operation of the door-locking device is more comfortable due to the decreased feeling of looseness.
