Abstract

The invention relates to a trailer coupling for a motor vehicle, with a coupling arm (11, 111, 211), on the free longitudinal end region (12) of which a coupling body (13), in particular a coupling ball (14), for the coupling of a trailer (190) or a load carrier (290) is arranged, and the other longitudinal end region (15) of which forms a holding end (16) for holding and/or movable mounting on a supporting structure (70) of the motor vehicle (90), wherein the coupling arm has supporting straps (20, 21) which extend along a longitudinal extent of the coupling arm at a transverse distance (22) to each other between the longitudinal end regions (12, 15). It is provided that the supporting straps (20, 21) are connected to each other by a plurality of connecting struts (26-31) in the manner of a lattice structure (24) or rib structure (25).
