<p>A car windscreen wiper with a frame (1) on the centre part of which is pivoted one or more end pieces (1a, 1b). The frame is partly flexible to push the end pieces towards the glass. This is done by a leaf spring (3b), made by moulding and fixed to one frame end. The leaf spring cross section diminishes from the frame to its free end, which has a fork pressing on the frame end. The spring cross-section is lozenge shaped, the larger diagonal parallel to the windscreen. The mouldings are of plastics.</p> |
