Abrégé

The present invention relate to a self-heating, automotive wiper blade and a wiper system, which use the heat generated by the exothermic reaction of a material with exothermic reactivity to maintain optimal performance of a wiper blade by maintaining optimal operation temperature using the heat from the exothermic material even in winter when external temperatures drop. The chemical reaction Induced type, self-heating wiper blade and wiper system according to the present invention, comprises: a first exothermic material located on a medial or lateral side thereof; and a second exothermic material located on the exterior thereof which comes into contact with first exothermic material to create an exothermic reaction and elevate the temperature.

Abrégé

According to the present invention, when a wiper blade is rotated to wipe a glass surface according to an operation of a wiper, the particles of a heat generating substance in the form of a liquid or a solid powder collide with each other to generate heat that is transferred to a wiping part of the wiper to increase the temperature of the entire wiper, thereby preventing the glass surface from becoming frosted. The wiper for a vehicle according to the present invention comprises a wiper blade formed of rubber and including: a wiping part at one side thereof to contact a glass surface of the vehicle; and a head part at the other side thereof. Further, the wiper comprises a hollow part formed within the wiper blade, and first heating reactants as liquid or solid powder type materials for generating heat. The hollow part is filled with the first heating reactants, and is sealed. When the wiper blade is rotated to wipe a glass surface, the first heating reactants collide with each other to generate heat that is transferred to the wiping part to increase the temperature of the wiper.

Abrégé

The present invention relates to a pressure-distributing variable type vehicle wiper blade in which a wiping member tightly contacts a glass surface to thoroughly clean the glass surface, and in which the curvature of an elastic body can be adaptively adjusted in accordance with the curvature of the glass surface, and the distribution of the pressure of the elastic body can be adjusted to enable the wiper blade to be easily used in glass surfaces having different curvatures. According to the present invention, provided is a pressure-distributing variable type vehicle wiper blade (100) comprising: a wiping member (110) for wiping a glass surface (1); a main elastic body (120) to which the wiping member (110) is fixed, and which is pressed by a wiper arm (200) so as to press the wiping member (110) tightly onto the glass surface; and an auxiliary elastic body (130) which applies pressure to the main elastic body (120) to permit the main elastic body (120) to press the wiping member (110).
