Abstract

A windshield wiper blade assembly includes an arched casing having an intermediate portion provided with a seat provided a rod, the arched casing having two arms each provided with a pair of opposite first pins, a pair of master blade holders each having a spoiler with two gradually decreasing ends each formed with a recess and provided with two aligned holes, the spoiler having two turbulent holes and a through hole between the two turbulent holes, the arched casing being engaged with the master blade holders with the pins engaged with the aligned holes, the master blade holders having a bottom formed with two longitudinal grooves, a pair of assistant blade holders each having an intermediate portion provided with a protruded end configured to engage with the recess of the spoiler, two second pins arranged under the protruded end adapted to engage with the aligned holes of the master blade holder, and a bottom provided with two protuberances each having a longitudinal groove, and a rubber blade fitted in the longitudinal grooves of the master and assistant blade holders, whereby a high downward pressure will be provided to the rubber blade against a windshield upon bearing of force of wind.

Claims

1. A windshield wiper blade assembly comprising:

an arched casing having an intermediate portion provided with a seat provided a rod, said arched casing having two arms each provided with a pair of opposite first pins;

a pair of master blade holders each having a spoiler with two gradually decreasing ends each formed with a recess and provided with two aligned holes, said spoiler having two turbulent holes and a through hole between said two turbulent holes, said arched casing being engaged with said master blade holders with said pins engaged with said through holes, said master blade holders having a bottom formed with two longitudinal grooves;

a pair of assistant blade holders each having an intermediate portion provided with a protruded end configured to engage with said recess of said spoiler, two second pins arranged under said protruded end adapted to engage with said aligned holes of said master blade holder, and a bottom provided with two protuberances each having a longitudinal groove; and

a rubber blade fitted in said longitudinal grooves of said master and assistant blade holders;

whereby a high downward pressure will be provided to said rubber blade against a windshield upon bearing of force of wind.

2. The windshield wiper blade assembly as claimed in claim 1, wherein said seat is formed with an elongated cavity and a curved rib under said rod for reinforcing structure thereof.
