  • Patent number: 7836541
    Abstract: A lever of a wiper blade holds a blade rubber. A cover accommodates at least a part of the lever from an opening. A nozzle mechanism has a connecting portion connected to a supply passage. A nozzle portion receives washer liquid that has been sent from the supply passage under pressure and passed the connecting portion, and supplies the washer liquid to a surface to be wiped. An attachment member is integrated with the nozzle mechanism. In a state where the cover accommodates the nozzle mechanism, the attachment member is attached to the lever or the cover. Therefore, the wiper blade is capable of stably supplies washer liquid to the surface to be wiped for an extended period of time.

  • Patent number: 7757337
    Abstract: A pipe member is arranged along a wiper arm. A wiper blade has a lever rotatably coupled to the wiper arm and a blade rubber for wiping a surface to be wiped. A nozzle mechanism has an attachment member attached to the wiper arm, a nozzle member for supplying the washer liquid sent under pressure from the pipe member to the surface to be wiped, and an engaging portion provided in the nozzle member. The attachment member rotatably supports the nozzle member. The engaging portion engages with the wiper blade such that the nozzle member follows rotation of the wiper blade. Therefore, a vehicle wiper device facilitates replacement of the wiper blade, and allows washer liquid to be stably received by the surface to be wiped.

  • Patent number: 7615955
    Abstract: A washer controller controls a washer motor in accordance with a manipulation of a washer switch. A washer switch detector determines whether a manipulation of the washer switch is performed within a predetermined time period of a last manipulation of the washer switch. A spray time controller sets a spray time to a first set time when the manipulation of the washer switch is performed within the predetermined time period of the last manipulation, and to a second set time when the manipulation of the washer switch is performed after the predetermined time period, the second set time being greater than the first set time. A washer motor controller operates the washer motor for a time period corresponding to the spray time set by the spray time controller.

  • Patent number: 7603742
    Abstract: A lever assembly holds a wiper strip, which directly wipes a wiping surface. The lever assembly includes a plurality of levers, which are connected together in tournament style. An axial length of the lever assembly is shorter than an axial length of the wiper strip. A cover member receives the lever assembly, and opposed ends of the cover member hold the wiper strip. The cover member includes a plurality of cover portions, which are formed separately from one another.
