  • Patent number: 9862356
    Abstract: A wiper blade having a spoiler-integrated lever assembly. The lever assembly of the wiper blade includes a connector seat to which a connector assembly for connection to a wiper arm is detachably connected. The connector assembly is detachably joined to the connector seat by inserting an insertion protrusion of the connector assembly to an insertion slot of the connector seat and then rotating the connector assembly towards the connector seat and thus bringing snap protrusions of the connector seat into snap-engagement with snap slots of the connector assembly.
    Type: Grant

  • Patent number: 9855923
    Abstract: A wiper blade suitable to six types of wiper arms. A connector assembly of the wiper blade is detachably joined to a lever assembly and is detachably connected to wiper arms having first to sixth coupling units at a distal end respectively. An adaptor of the connector assembly is rotatably attached to the lever assembly. A slide cover of the connector assembly is slidably joined to the adaptor. A side lock cover of the connector assembly is detachably joined to the adaptor. The slide cover is moved to the adaptor in a first movement direction parallel to a longitudinal direction of the lever assembly to cover top contact surfaces of the first to third coupling units. The adaptor is fitted to the fourth coupling unit. The adaptor is connected to the fifth and sixth coupling units by a side pin passing through the side lock cover.

  • Patent number: 9845074
    Abstract: A wiper blade suitable to three types of wiper arms. A connector assembly of the wiper blade is detachably connected to wiper arms having first to third coupling units at a distal end respectively. The connector assembly has an adaptor and a slide cover slidably joined to the adaptor. The slide cover is moved to the adaptor in a first movement direction to fix the first to third coupling units to the adaptor and is moved from the adaptor in a second movement direction opposite to the first movement direction to release fixation between the coupling units and the adaptor. The adaptor has a support protrusion supporting support surfaces of the first to third coupling units. The slide cover has a push surface contacting the contact surfaces of the first to third coupling units to push the first to third coupling units towards the support protrusion of the adaptor.

  • Patent number: 9669803
    Abstract: A wiper blade wherein a spoiler is integrated in a lever assembly. The wiper blade has a wiper rubber and the lever assembly holds the wiper rubber and connects to a wiper arm. The lever assembly has a plurality of rotatably connected levers. A longitudinally extending partial spoiler is formed in at least one of the plurality of levers. The lever assembly includes a lever joint rotatably interconnecting adjacent levers. The lever joint is interposed between one of adjacent levers and the other of the adjacent levers. The lever joint is fitted to the one of the adjacent levers through insertion in the longitudinal direction of the lever assembly and is rotatably coupled to the other of the adjacent levers through pressing.
