Abstract: A connecting unit for a flat wiper blade is provided. The connecting unit separably connects the flat wiper blade to a wiper arm having one of the following: a first coupling element including a top plate and a pair of side plates having a concave portion at a rear end; a second coupling element including a top plate and a pair of side plates; and a third coupling element including a side pin and a clip arm. The connecting unit has a bracket fixed to a frame of the flat wiper blade and an adaptor. The adaptor is pivotally mounted on the bracket via a pivot shaft of the bracket. The adaptor has first to third fixing devices separably fixing the adaptor to the first to third coupling elements respectively. The flat wiper blade is connected to the wiper arms via the adaptor.

Abstract: A connecting unit for separably connecting a flat wiper blade to a hook wiper arm is provided. The connecting unit has a bracket fixed to a frame of a flat wiper blade, an adaptor pivotally mounted on the bracket and a cover pivotally attached to the adaptor. The adaptor and a linear section of a hook wiper arm are fixed via a first fixing element of the adaptor in a lateral direction of the linear section. The adaptor and a curved section of the hook wiper are fixed via a second fixing element of the adaptor and a third fixing element of the cover in a longitudinal direction of the linear section. When a first locking element of the adaptor and a second locking element of the cover engage each other, the third fixing element fixes the curved section relative to the second fixing element.
