Problems solved by technology

[0009] However, in the stopped state of the above-mentioned wiper system, the wipers can be clearly identified as separate wipers, giving the impression that the wipers are not integral and thus conspicuous
Therefore, the appearance of the portion of the vehicle where the wiper is provided is deteriorated and degraded

[0041] A first embodiment of the present invention will be described below with reference to FIGS. 1-9C.

[0042] As shown in Figures 1-3, the wiper system W of the present invention is an opposed wiper system for reciprocally wiping the wiping surface 1a of the windshield 1 (hereinafter referred to as glass 1) of the vehicle, and the wiper system of the present invention The system W includes two wiper mechanisms W1, W2. The wiper mechanisms W1 , W2 are arranged one after the other in the lateral direction of the vehicle, indicated by a double-headed arrow T in FIGS. 1-3 .

[0043] The wiper mechanism W1 includes a wiper motor 10 , a wiper arm 20 , a wiper blade 30 and a cover (also referred to as a cover portion) 40 . The wiper motor 10 is mounted on the lower right corner of the glass 1 and is configured in a substantially rectangular shape. The wiper arm 20 is fixed to a base end portion of the wiper motor 10 . The wiper blade 30 is rotatably connected to an end portion...

[0107] Next, a second embodiment of the present invention will be described with reference to FIG. 12A, and variations thereof will be described with reference to FIGS. 12B and 12C. Here, please note that in the second embodiment and subsequent embodiments, elements similar to those of the first embodiment will be denoted by the same symbols, and further description will not be given for simplification.

[0108] In a first embodiment, the wiper system W is an opposed wiper. However, the present invention is not limited thereto. In particular, as shown in FIG. 12A , the wiper system according to the second embodiment is a tandem wiper system, and two wiper mechanisms start reciprocating and swinging in a common direction to wipe from corresponding storage positions.

[0109] Referring to FIG. 12A , two wiper mechanisms are respectively arranged on the right side of the vehicle and at or around the lateral center of the vehicle. The right side wiper mechanism provided to the r...

[0116] Now, a third embodiment of the present invention will be described with reference to FIGS. 13-16.

[0117] In the first embodiment, the wiper arms 20, 60 are independently driven by independent wiper motors 10, 50, respectively. However, the present invention is not limited thereto.

[0118] As shown in FIGS. 13-15 , the wiper system W according to the third embodiment includes two wiper arms 20 , 60 , two wiper blades 30 , 70 , two covers 40 , 80 and a moving mechanism 100 . As an alternative to the wiper motors 10 and 50 , the wiper system W of this embodiment includes a wiper motor 200 and a link mechanism 210 .

[0119] The wiper motor 200 is an electric motor that rotates unidirectionally to reciprocally swing the wiper arms 20 , 60 . Alternatively, the wiper motor 200 may rotate forward and backward to reciprocally swing the wiper arms 20 , 60 .

[0120] Linkage mechanism 210 includes crank arm 211 , rod 212 , crank 213 , rod 214 , rod 215 , lift motor 216 , cr...

Abstract

Wiper blades are connected to wiper arms, respectively, to wipe a wiping surface of a vehicle front window glass. One of the wiper arms includes a cover portion, which at least partially covers at least one of the other wiper arm and the wiper blade connected thereto to continuously arrange the wiper arms one after the other along a lower edge of the wiping surface when each of the wiper blades is placed in a corresponding storage position thereof.

Description

technical field [0001] The invention relates to a wiper system. Background technique [0002] In a known type of wiper system, for example, two wiper blades reciprocally wipe the wiping surface of the windshield of the vehicle. When each wiper blade is placed in their swinging rotational position (hereinafter simply referred to as "rotational position"), the wiper blades are arranged parallel to each other so that overlapping portions of the wiper blades overlap each other to form an overlapped portion. Specifically, in an opposed pattern wiper system, two wiper arms (more specifically, the wiper arm and the wiper blade attached thereto) respectively swing reciprocally in opposite directions to wipe the wiper surface. . Thus, in one rotational position, the wiper blades are arranged parallel to each other and form longitudinally overlapped portions. [0003] When the above-mentioned wiper system is arranged on the lower part of the vehicle windshield, the overlapping part...
