ABSTRACT:
An energy absorbing wiper system for a vehicle, including: a pivot shaft to which a wiper arm is fixed; a pivot shaft holder into which the pivot shaft is rotatably inserted; an impact absorbing portion provided between the pivot shaft and the pivot shaft holder, the impact absorbing portion being adapted to be broken or deformed when a certain load is applied thereto to thereby permit the movement of the pivot shaft in a sinking direction relative to the pivot shaft holder; and, an energy absorbing member interposed between the wiper arm and the pivot shaft holder, the energy absorbing member adapted to be broken or deformed while permitting the sink of the pivot shaft when the pivot shaft moves in the sinking direction after the impact absorbing portion has been broken or deformed, to thereby absorb the moving energy of the pivot shaft.
