A reinforcement part for reinforcing a vehicle component, comprising a structural wall extending along a longitudinal axis (X) of the reinforcement part, wherein the structural wall at least partly encloses walls of a ribbing structure for supporting structural strength of the reinforcement part, the reinforcement part, when viewed in cross-section, having a first side region configured for allowing a first load portion to pass through and a second side region configured for allowing a second load portion to pass through, wherein the first load portion represents the largest load portion occurring at the cross-section, wherein the ribbing structure is at least provided at the first side region and the second side region, characterized in that at the second side region, when viewed along the longitudinal axis, the walls of the ribbing structure are provided with cut-outs, the structural wall at the second side region being shaped to at least partially cover the contours of the cut-outs, in such a way, that a continuously shaped cut-out is formed in the structural wall for routing cabling, whereas the walls of the ribbing structure at the first side region are free from cut-outs to keep the ribbing structure at the first side region intact, wherein the second load portion represents the smallest load portion occurring at the cross-section, and wherein, when viewed in cross-section, the structural wall has an open side, the first side region comprising the open side, the walls of the ribbing structure at the open side being free from cut-outs.
