Abstract
(DE)
Die Erfindung geht aus von einer Wischleisteneinheit mit zumindest einer Wischlippe (12a; 12b) und mit zumindest einem Wischgrundkörper (14a; 14b), welcher zumindest eine Federschienenaufnahme (16a; 16b) zu einer Aufnahme einer Federschiene (17a; 17b, 19b) und zumindest einen von der Federschienenaufnahme (16a; 16b) verschiedenen, in Umfangsrichtung geschlossenen, Längskanal (18a; 18b) aufweist. Es wird vorgeschlagen, dass die Wischlippe (12a; 12b) zumindest eine wesentliche Ausnehmung (20a; 20b) aufweist, welche den zumindest einen Längskanal (18a; 18b) in Richtung der Wischlippe (12a; 12b) erweitert.
(EN)
The invention relates to a wiper strip unit having at least one wiper lip (12a; 12b) and at least one wiper body (14a; 14b) which comprises at least one spring rail holder (16a; 16b) for receiving a spring rail (17a; 17b, 19b) and at least one longitudinal channel (18a; 18b) which is closed in the circumferential direction and differs from the spring rail holder (16a; 16b). According to the invention, the wiper lip (12a; 12b) has at least one substantial recess (20a; 20b) which extends the at least one longitudinal channel (18a; 18b) towards the wiper lip (12a; 12b).
(FR)
L'invention concerne une unité formant lame d'essuyage comprenant au moins une raclette (12a ; 12b) et au moins un corps de base d'essuyage (14a ; 14b), lequel comporte au moins un logement (16a ; 16b) pour rail élastique servant à loger un rail élastique (17a ; 17b, 19b) et au moins un conduit longitudinal (18a ; 18b) différent du logement (16a ; 16b) de rail élastique, fermé dans la direction périphérique. L'invention propose que la raclette (12a ; 12b) comporte au moins un évidement (20a ; 20b) principal, lequel élargit le ou les canaux longitudinaux (18a ; 18b) en direction de la raclette (12a ; 12b).
