Provided is a wiper blade wherein: a pair of accommodation sections are disposed in both sides in the short direction of a holder main body () so as to sandwich a holding section () therebetween; a pair of vertebrae that elastically deform a blade rubber () to match the curvature of a front glass are accommodated in each accommodation section; an insertion opening (O) capable of inserting a main body section () is disposed between an end cap () and the holder main body (); and a guiding section () that guides the main body section () towards the holding section () is disposed on the end cap () side where the insertion opening (O) is formed.

Wiper blade and method of assembling the same

Provided is a wiper blade wherein: a pair of accommodation sections () are disposed so as to sandwich therebetween a holding section () that holds a main body section (); a vertebra () is accommodated in each of the accommodation sections (); an arm connection member () to which a wiper arm is connected is fixed to each vertebra (); a rubber pressing section () that presses the main body section () towards a front glass is disposed in a section of the holding section () that faces the front glass; and a holder pressing section () that presses a holder member () towards the front glass by the elastic force of each vertebra () is disposed in the section of each accommodation section () that faces the front glass, further on the front glass side than the rubber pressing section ().

Wiper blade

A fin part () is provided on a side opposite to a wiping surface side of a rubber holder () to press a blade rubber () toward the wiping surface side by receiving a wind (W) flowing along a moving car, and covering parts () protrude from both lengthwise ends of the blade rubber () toward the wiping surface side so as to partially cover lateral parts of the blade rubber (). Owing to the fin part (), liftoff of a wiper blade () can be prevented. A wind (W) flowing from the front side to the rear side at an end part of a swing center side of the blade rubber () can be rectified by the covering part (), and the wind (W) can flow along the rear side of the wiper blade () in the length direction of the wiper blade ().

The wiper system with translational motion is additionally capable of moving the wiper arm in angular motion at an auto stop position so that the wiper blade may be stowed away from the view of the vehicle operator when the wiper system is not in use. The retracted position may be defined immediately below the lower edge of the windshield. When a mist switch is turned on so as to effect a quick wiping action, the wiper arm can angularly move from the retracted position to the upright position. When the wiper arm is already in the translational motion, turning on of the mist switch may increase the speed of the translational motion. To prevent the wiper blade from obstructing the view of the vehicle operator in an intermittent mode, the position of the temporary stop of the wiper blade may be selected at the reversing position which is remote from the vehicle operator. If the interval of the intermittent operation of the wiper arm is relatively short, the position of the temporary stop may then be selected at the auto stop position because the duration of the temporary stop is so short that the obstruction of the view of the vehicle operator is insignificant.

In a washer nozzle assembly, the upper lip portion defining a nozzle opening extends more forwardly than the lower lip portion so that the part of the washer liquid directed upward is blocked by the longer upper lip portion, and the upper part of the spray pattern includes more liquid droplets of larger sizes as compared to the prior art. Thus, the loss of washer liquid by being flown above the windshield at high speed can be reduced, and the spray pattern of the washer nozzle assembly can be optimized for all speeds.
