- the connecting rod 61 has a stiffening rib 66 between the two joints 64 in order to avoid kinking of the connecting rod 61. Between the stiffening rib 66 and the joints 64, an opening 65 is provided on each side of the connecting rod 61.
- the opening 65 may serve to pivot the hinge 64 at an alternative point of the connecting rod 61, so as to change the gear ratio of the crank mechanism 60 and adapt, so that the crank mechanism 60 is flexible for different wiping angle or vehicle types used.
- the joint 64 on the first crank 63 is located radially further inwardly on the crank 63 than the joint 64 on the second crank 62.
- the first crank 63 is rotated by a uniform rotational movement of the output shaft 12 , so the first crank 63 can rotate completely around the drive axis.
- the second crank 62 which couples the wiper arm in the through the crank drive 60 is formed longer than the first crank 63, so that the second crank 62 sets the Schwschwinkel and alternately oscillates back and forth only in this area causes the wiping angle of the wiper arm due to the translation and this moves by means of the Wscherwelle 20.
- the support member 5 is formed in one piece and of the same material in the embodiment.
- a material for the carrier element 5 is particularly suitable an aluminum or an aluminum alloy.
- the carrier element can be produced here in an injection molding process or a forging process.
- the carrier element 5 is formed substantially trough-shaped and comprises three legs 50, 51, 52.
- a first leg 50 is arranged on the right side of the output shaft 12 in the figures.
- a second leg 51 and a third leg 52 are arranged substantially opposite to the first leg 50.
