Wiper blade

A wiper unit comprises a wiper motor provided with a motor yoke and a gear case screwed to the motor yoke, a motor arm, a wiper frame, a pivot shaft, a pivot arm and a link connecting rod. The gear case of the wiper motor is formed with a frame-holder portion having a semi-circular cross section to be fitted with the wiper frame for supporting the wiper frame, and the wiper frame is secured to the frame-holder portion of the gear case by, for example, tightening a screw.

A link connecting rod for wiper apparatus is provided with a tubular rod body, a plate portion with a first and a second plane flattened by compressing an end of the rod body, a semicylindrical portion with a third plane having a semicircular cross section and disposed between the rod body and the plate portion, a first brim portion with a fourth and a fifth plane flattened by compressing one side of the semicylindrical portion and a second brim portion with a sixth and a seventh plane flattened by compressing another side of the semicylindrical portion. The plate portion, the semicylindrical portion, the first and second brim portions are formed by pressing the end of the rod body on the base level of the second, the third, the fifth and seventh planes which are all in one plane.

Link connecting rod for wiper apparatus

A ball joint, which is composed of a ball pin, a retainer connected with the ball pin and an elastic joint seal having first and second apertures for covering the ball pin and the retainer. The ball joint is assembled very easily by pressing the ball pin against the second aperture of the joint seal which has been previously set on the retainer, at a predetermined relative speed higher than 20 cm/s after applying lubricant on the inner peripheral face of the second aperture of the joint seal.

A vehicular windshield washer system in combination with a windshield wiper having a wiper arm. The washer system is comprised of a pair of washer nozzles mountd on the wiper arm and so directed to eject washer fluid to opposite sides of the wiper arm upon being supplied with washer fluid. The washer fluid from a washer fluid source is selectively supplied to the washer nozzles in accordance with movement of the wiper arm. The washer fluid is suppliable to one of the washer nozzles upon rotational movement of the wiper arm in one direction and to the other washer nozzle upon rotational movement of the wiper arm in the other direction. The rotational movements turn at a turning position of the wiper arm. Additionally, the washer fluid is supplied to the one washer nozzle until the wiper arm reaches a position slightly forward of the turning position and stopped to be supplied to the same washer nozzle for a duration of rotational movement of the wiper arm from the slightly forward position to the turning position, thereby saving washer fluid and preventing washer fluid from scattering sideward of a vehicle body.

Herein disclosed is a wiper which can selectively assume a 'semi-concealed mode' and a 'full-concealed mode'. The wiper comprises an output gear housed in a case, an output shaft having one end to which a motor arm is secured, a wiper arm assembly including a connecting rod which is pivotally connected to the motor arm, a first mechanism for transmitting rotation of the output gear to the output shaft, a bushing rotatably housed in the case and having an eccentric bore through which the output shaft is rotatably passed, a second mechanism for locking the bushing to one of the case and the output gear while changing relative angular positioning between the bushing and the output gear, and a push button arranged on the case and actuating the second mechanism when manipulated.

A control lever is driven by a driving unit to cause variation in tension of a coil spring and therefore variation in force with which a wiper blade is pressed against a windshield. The driving unit is disposed in an arm head and includes a geared motor, a male screw member in the form of a bolt and secured to an output shaft of the geared motor and a female screw member having an internally threaded socket portion screwed onto the male screw member and a sliding portion in the form of a rectangular bar and installed in a guide member for longitudinal movement but against rotation. The output shaft of the geared motor, male screw member and the female screw member are so arranged as to have axes in line with each other and exending longitudinally of the arm head.

Windshield wiper with means for adjusting force with which wiper blade

A novel and useful automotive wiper device, of which the depression force can be adjusted with a compact mechanism for adjusting the depression force of the wiper blades. The automotive wiper device employes a plurality of springs exerting a biasing force on a wiper arm and a wiper blade against a vehicular window surface. At least one of the springs has an adjustable spring force. The adjustable spring is associated with an adjusting means which allows adjustment of the spring force thereof.

An air conditioner of an automatic temperature adjusting type used particularly for controlling the air temperature within a passenger compartment of an automotive vehicle. According to the present invention, the air conditioner controls simultaneously the air flow rate of a fan providing the air supply, and an air mixing door which controls the flow of air through either a heater or a bypass around the heater. The control is such that over an intermediate portion of the adjustment range the fan and air mixing door are operated together whereas at end portions of the adjustment range the fan is adjusted without moving the air mixing door. This is achieved by use of a particularly convenient gear mechanism of novel design.
