A wiper arm device comprising a wiper arm unit (10a;
- 10b;
- 10c;
- 10d;
- 10e;
- 10f;
- 10g;
- 10h;
- 10i;
- 10j;
- 10k) which has at least one wiper rod (12a), and at least one nozzle unit (14a;
- 14c;
- 14i) which is provided for applying washer fluid onto a vehicle window, and which, in an installed state, is arranged at least substantially laterally on the wiper arm unit (10a;
- 10b;
- 10c;
- 10d;
- 10e;
- 10f;
- 10g;
- 10h;
- 10i;
- 10j;
- 10k), characterized in that the at least one nozzle unit (14a;
- 14c;
- 14i), in an installed state, is arranged at least substantially as an extension of the wiper rod (12a) of the wiper arm unit (10a;
- 10b;
- 10c;
- 10d;
- 10e;
- 10f;
- 10g;
- 10h;
- 10i;
- 10j;
- 10k) and is fastened to the wiper arm unit (10a;
- 10b;
- 10c;
- 10d;
- 10e;
- 10f;
- 10g;
- 10h;
- 10i;
- 10j;
- 10k) by a latching connection, wherein the wiper arm unit includes at least one substantially rigid first holding element (20a;
- 20b;
- 20c;
- 20d;
- 20e;
- 20f;
- 20g;
- 20h;
- 20i;
- 20j;
- 20k) on which the at least one nozzle unit is fixed in the installed state, and at least one substantially rigid second holding element (28a;
- 28b;
- 28c;
- 28d;
- 28e;
- 28f;
- 28g;
- 28h;
- 28i;
- 28j;
- 28k) on which the at least one nozzle unit is fixed in the installed state, wherein the at least one second holding element is longitudinally spaced apart from the at least one first holding element along a main direction of extent (46a;
- 46b;
- 46c;
- 46d;
- 46e;
- 46f;
- 46g;
- 46h;
- 46i;
- 46j;
- 46k) of the wiper rod (12a), wherein a main plane of extent of the at least one first holding element and a main plane of extent of the at least one second holding element enclose an angle of approximately 90°, wherein the at least one nozzle unit (14a, 14c, 14i) has at least two first spring elements (38a, 40a) which are deflected by the at least one first holding element, and between which the at least one first holding element (20a, 20b, 20c, 20d, 20e, 20f, 20g, 20h, 20i, 20j, 20k) is latched in the installed state.
