  • Patent number: 8381349
    Abstract: A windshield wiper blade assembly comprises: a middle housing having a middle frame segment that defines an accommodating recess; an elastic wiper blade; and a bridging member fitted in the accommodating recess. The bridging member has two end parts, a middle part and a pivot part. The pivot part protrudes upwardly from a top wall of the middle part. Each of the end parts has a top edge extending upwardly from the top wall so as to cooperate with the pivot part to define an extension recess. At least one of the end parts engages the middle frame segment in a tongue-and-groove engaging manner and at least one of the end, parts and the middle part engages the middle frame segment in a snap-fit engaging manner.
