Problems solved by technology

[0007] However, the wiper strip 2 tends to shrink and become stiff in the cold winter months
After losing its elasticity, the wiper strip 2 cannot make close contact with the windshield surface
Specifically, the ends of the wiper strip 2 are slightly separated from the windshield surface, which results in a reduced contact area between the wiper strip and the windshield surface

Abstract

A wiper blade is provided capable of wiping a windshield of a vehicle in a suitable operating condition even in a cold winter season. The wiper blade includes a wiper strip configured to contact and wipe a glass surface of the windshield, a frame coupled to the wiper strip, an adapter disposed at a center of the frame and configured to be joined to the wiper arm, and a heating unit attached to the frame to heat the wiper blade. The heating unit includes a power source and a heating element heated by power supplied from the power source.

Description

technical field [0001] The present invention relates to a wiper blade coupled to a wiper device for wiping the windshield of a vehicle, and more particularly to a wiper blade incorporating a heating element to allow the wiper blade to Wipe the windshield of the vehicle under suitable operating conditions in cold winter. Background technique [0002] see figure 1 , a conventional wiper device includes: a wiper arm 9, which is pivoted in the left and right direction by a motor (not shown) provided in the vehicle; and a wiper blade 1, which is coupled to the wiper arm 9, so as to move along the wiper arm 9 . The wiper blade 1 includes a wiper strip 2 that wipes a glass surface of a vehicle windshield (not shown) while reciprocating on the windshield in a state of close contact. [0003] The wiper blade 1 is coupled to the wiper arm 9, and pivots at a predetermined angle by operation of a motor. Conventionally, a wiper blade 1 comprises: a first link part 3, which is joined ...
