ABSTRACT:
A windshield wiper construction having an armature comprising a main support element adapted to be an actuator arm, the main support element carrying a pair of rocker elements which mount a lodging element for a flexible wiper blade, the principal feature of the construction comprising the use of first coupling means for detachably connecting the rocker elements to the opposite ends of the main support element for rotational movement relative thereto, the first coupling means permitting the rocker elements to be disengaged only when they are rotated to a predetermined position relative to their normal position of use, and second coupling means for connecting the lodging element to each of the rocker arms for both limited axial and transverse movement of the lodging element relative to the rocker elements, the arrangement permitting limited rotational movement of the rocker arms relative to the main support element during normal use preventing their movement to a position in which they may be disengaged from the main support element.
