A windscreen wiper blade (1) comprises a harness (3, 5, 7) carrying a blade rubber (23) for wiping contact with the windscreen and having means (17) for connection with a wiper arm (11) for driving the blade (1) across the screen, in which the longitudinal central plane (.alpha.) through at least a part of the harness (3, 5, 7) lies at an angle (.theta.) to the longitudinal central plane (.beta.) of the blade rubber (23).

There is described the combination of a connector, which is an elongate element having parallel side faces and penetrated by a bore perpendicular to the side faces, and a pivot pin which is, in use, received in the bore and protrudes from both ends thereof, the pivot pin being retained in the bore by means of a resiliently supported projection extending either radially into the bore or radially outwardly from the pin, the resilient projection engaging the side walls of either a groove formed in the pin, or of a recess formed in the connector and communicating with the bore. The connector is situated, in use, in an elongate opening in a wiper blade harness, parallel side walls of the opening being formed with holes into which the ends of the pin project to mount the connector pivotally to the wiper blade harness, and the connector is adapted to engage and retain an end of a windscreen wiper arm to effect a pivotal connection between the arm and the blade harness.

Wiper blades

A windscreen wiper blade harness comprising a plurality of metal yokes of channel cross section having at least one secondary yoke nested within and pivotally secured to primary yoke adjacent its end includes a plastic spacer of channel cross section disposed between the primary and secondary yokes for preventing metal to metal contact and providing the pivotal connection, the spacer being formed with a pair of internally extending aligned trunnions, one on each cheek which pivotally engage corresponding holes in the flanges of the secondary yoke, externally extending projections aligned with the internal trunnions which engage in corresponding holes in the flanges of the primary yoke and a radially extending flange which abuts the end of the primary yoke.
