Abstract
A wiper system (10), comprising a wiper arm (12) having a geometrical axis of rotation (x), a connecting arrangement (14) configured to connect the wiper arm to a motor-driven rotating shaft (100), wherein the connecting arrangement is configured to transfer the rotating motion of the shaft into a rotating motion of the wiper arm about said geometrical axis of rotation, a spring arrangement (24) configured to resiliently press the wiper arm against the connecting arrangement in the axial direction, and a tilting arrangement (30) configured to vary the inclination of the pressed wiper arm relative to said geometrical axis of rotation based on the rotational position of the wiper arm about said geometrical axis of rotation. There is also provided a vehicle comprising such a wiper arm system.

A wiper system, comprising:
- a wiper arm having a geometrical axis of rotation, the geometrical axis of rotation extending in an axial direction,
- a connecting arrangement configured to connect the wiper arm to a motor-driven rotating shaft, wherein the connecting arrangement is configured to transfer a rotating motion of the shaft into a rotating motion of the wiper arm about the geometrical axis of rotation,
- a spring arrangement configured to resiliently press the wiper arm against the connecting arrangement in the axial direction, and
- a tilting arrangement configured to vary an inclination of the pressed wiper arm relative to the geometrical axis of rotation based on a rotational position of the wiper arm about the geometrical axis of rotation.
