A support component for a motor vehicle which defines a support plane and defines two opposed side faces for an arrangement of functional components of a motor vehicle window lifter, wherein the support component includes at least one reinforcing structure for reinforcing the support component, which on both a first and a second side face extends along the support plane and along a direction of extension, wherein the support component forms at least two surface segments which on both the first and second side faces are arranged in the direction of extension of the reinforcing structure along the support plane, wherein the reinforcing structure is formed such that, on the first side face, the reinforcing structure extends in a manner protruding with respect to both surface segments transversely to the support plane (xz-plane) and, on the second side face, extends in a manner set back with respect to one surface segment of the at least two surface segments and protruding with respect to another surface segment of the at least two surface segments.
