1. A wiper device having a wiper arm (20c), having at least one wiper blade which is coupled to the wiper arm (20c), wherein the wiper blade extends along a longitudinal axis, wherein the wiper blade includes at least one wiper lip (22c) for wiping a surface (16c) of a protective element (14c) of a sensor device, wherein the wiper device includes a wiper arm guide unit (24c) which is provided for moving the wiper arm (20c) in an at least substantially translatory manner along a guide path, characterized by a rotary joint by means of which the wiper blade is pivotably mounted on the wiper arm (20c) about a rotation axis (28c), wherein the rotation axis is perpendicular to the longitudinal axis and is configured to be parallel to the surface, wherein the wiper arm (20c) is linearly adjustable along an adjustment axis (64c), wherein the wiper device further includes a contact pressure unit (44c) having a spring element (74c) which is provided for generating a contact pressure force (47c) for pressing the wiper lip (22c) onto the surface (16c) of the protective element (14c), wherein the spring element is a tension spring that extends parallel to the adjustment axis (64c) when the wiper lip (22c) is pressed onto the surface (16c).
