Windscreen wiper blade-setting angle measurer - has mutually movable parts with rotation angle markings enabling measurement without blade removal

摘要

An arrangement for measuring the setting angle of a wiper blade (2) contains a first part with a three-point support resting on the windscreen, a second part (16) rotatably mounted on the first part and markings for indicating the angle of rotation between the two parts. The second part has a support surface (18) which can be applied to the blade's suspension box (7). The rotation axis (17) on which the two parts are linked together lies in the blade's longitudinal direction.
