Abstract: The invention relates to a lidar device (10a-10l) having a cleaning unit (12a-12l) which has at least one wiper unit (14a-14l) having at least one wiper blade (16a-16l) for mechanically cleaning a cover element (18a-18l) of a lidar unit (20a-20l), and having at least one pressing element (22a-22l) which in a mounted state provides a pressing force for the wiper blade (16a-16l).

Abstract: A wiper device (10a-10f) for wiping a sensor system (30a-30f), in particular a lidar system, with at least one wiper unit (12a-12f), which comprises at least one wiper lip (16a-16f) for wiping a surface (38a-38f) of the sensor system (30a-30f) and with at least one pressing unit (14a-14f). It is proposed that the pressing unit (14a-14f) comprises at least one spring element (24a; 52b; 54c, 56c; 58d; 60e; 62f, 64f) for pressing the wiper unit (12a-12f) against the surface (38a-38f).

Abstract: A wiper device having a wiper arm (20a; 20b; 20c), having at least one wiper blade (18a, 18a?, 18a?) which is coupled to the wiper arm (20a; 20b; 20c), which includes at least one wiper lip (22a, 22a?, 22a?) for wiping a surface (16a; 16b; 16c) of a protective element (14a; 14b; 14c) of a sensor device (12a), in particular of a Lidar device, and having a wiper arm guide unit (24a) which is provided for moving the wiper arm (20a; 20b; 20c) in an at least substantially translatory manner along a guide path (50a). It is proposed that the wiper device has a rotary joint (26a) by means of which the wiper blade (18a, 18a?, 18a?) is pivotably mounted on the wiper arm (20a; 20b; 20c).

Abstract: A wiper arm and a windscreen wiper system, wherein the wiper arm comprises a joint part and a lever part and a spring, wherein the parts form a common joint. The spring is embodied here as a torsion spring.
