Abstract: A skid plate for a robotic lawnmower, comprises an approximately circular plate with a central opening (13), for a hub (6b), and means of attachment (14, 15). The skid plate (2b) is attachable to the robotic lawnmower. An edge portion (7) of the circular plate is bent to extend transversally to a main plane (8) of the circular plate. An outer peripheral edge (11) thereof extends in a single plane. A robotic lawn mower comprises an electric motor connected to a rotatable cutting head (1b). The cutting head is connected to a cutting disk (3b) with at least one knife (4b) at its periphery. A skid plate (2b) as above is arranged below the cutting disk (3b).

Abstract: An underrun protection arrangement for a vehicle includes a frame, an impact element for receiving impact in case of a collision, and a first energy absorbing element arranged between the frame and the impact element for absorbing energy in case of a crash while allowing a first displacement of the impact element in relation to the frame. A second energy absorbing element is arranged between the first energy absorbing element and the frame for absorbing energy while allowing a second displacement of the impact element in relation to the frame.
