ABSTRACT:
The wiper blade apparatus includes an elongate blade element for wiping a surface. The blade element has opposite end portions. First and second attachment mechanisms are attached to the end portions of the blade element. The first attachment mechanism is disposed a blade distance from the second attachment mechanism. A holding member is in operative engagement with the blade element and the holding member has opposite end portions. The holding member is bow shaped and has a bendable and spring biased segment. Third and fourth attachment mechanisms are attached to the end portions of the holding member and the third attachment mechanism is disposed a holder distance from the fourth attachment mechanism. The first attachment mechanism is in operative engagement with the third attachment mechanism and the second attachment mechanism is in operative engagement with the fourth attachment mechanisms so that the blade element is removably attached to the holding member. The holder distance is greater than the blade distance so that the blade element is subjected to a tensile force when the first attachment mechanism of the blade element is attached to the third attachment mechanism of the holding member and the second attachment mechanism of the blade element is attached to the fourth attachment mechanism of the holding member.
