A spring including helical portion (1) with an open U-shaped hook (6, 8, 10 and 7, 11, 2) at each end. The helical portion (1) is formed in the region of the pivot (9) of the wiper support arm (3) at the base portion (4) retaining said support arm (3). One hook (7, 11, 2) extends over and is hooked under the support arm (3) while the other hook (6, 8, 10) extends under and is hooked over the base portion (4). The spring substantially increases the pressure exerted on the windscreen by the rubber wiper blade and remains correctly hooked even when the support arm (3) is pivoted away from the windscreen.
Le ressort comprend une portion hélicoïdale intermédiaire (1) avec un crochet ouvert en forme de U (6, 8, 10 et 7, 11, 12) à chaque extrémité. La portion hélicoïdale (1) est disposée dans la région du pivot (9) du bras de soutien (3) d'essuie-glace à la partie de base (4) qui retient le bras de soutien (3). Un crochet (7, 11, 2) entoure le bras de soutien (3), passant au-dessus et s'accrochant sous celui-ci et l'autre crochet (6, 8, 10) entoure la partie de base (4), passant sous et s'accrochant sur le dessus de la partie de base. Le ressort accroît considérablement la pression exercée par la lame de caoutchouc contre le pare-brise. Le ressort demeure accroché correctement même si le bras de soutien (3) est pivoté de façon à s'éloigner du pare-brise.
