Wiper blade

A wiper blade, comprising:

• a wiper rubber;
• a lever assembly holding the wiper rubber, the lever assembly comprising a plurality of levers, adjacent levers of which are rotatably connected;
• and
• a connector assembly detachably connected to a wiper arm, the wiper arm including one of first to third coupling units at a distal end, each of the first to third coupling units having:
• a receiving portion extending in front and rear directions;
• a contact surface and a support surface for fixation in the front and rear directions;
• and a tongue for fixation in a vertical direction vertical to the front and rear directions,
• wherein the connector assembly includes:
• a bracket detachably joined to the lever assembly and having a rotation shaft;
• an adaptor rotatably mounted to the bracket through the rotation shaft;
• and
• a slide cover slidably joined to the adaptor, the slide cover being moved to the adaptor in a first movement direction parallel to a longitudinal direction of the lever assembly to fix one of the first to third coupling units to the adaptor, the slide cover being moved from the adaptor in a second movement direction opposite to the first movement direction in the longitudinal direction of the lever assembly to release fixation between the one of the first to third coupling units and the adaptor,
• wherein the adaptor includes:
• an insertion portion having a pair of lateral walls rotatably coupled to the rotation shaft, the insertion portion being inserted into the receiving portion of the one of the first to third coupling units;
• a first support protrusion formed at an end of the insertion portion in the first movement direction and supporting the support surface of one of the first and second coupling units when the one of the first and second coupling units is connected to the adaptor;
• and
• a second support protrusion formed at the end of the insertion portion in the first movement direction and supporting the support surface of the third coupling unit when the third coupling unit is connected to the adaptor, and
• wherein the slide cover includes:
• a first push surface contacting the contact surface of the one of the first and second coupling units when the one of the first and second coupling unit is connected to the adaptor to push the one of the first and second coupling units towards the first support protrusion in the first movement direction;
• a second push surface contacting the contact surface of the third coupling unit when the third coupling unit is connected to the adaptor to push the third coupling unit towards the second support protrusion in the first movement direction;
• a hood covering the tongue of the one of the first and second coupling units when the one of the first and second coupling units is connected to the adaptor;
• and
• a latch surface covering at least a portion of a top surface of the tongue of the third coupling unit when the third coupling unit is connected to the adaptor.
