A sun visor for motor vehicles comprising an integrally moulded substantially flat, generally rectangular unitary body comprising two substantially rectangular half shells integrally joined along one of their longer edges, with a longitudinal reinforcing rib extending along this edge between the two half shells. Projecting from the longitudinal rib there are a plurality of transverse ribs, also integrally formed with the half-shells. A method of manufacturing the sun visor is also disclosed. This involves the use of a mould having a central mandrel and two outer dies. The mould is shaped such that the body is initially moulded with the two half-shells divergent from one another in the region of the long edge opposite the edge having the longitudinal reinforcing rib, the edges of the half shells are welded together to complete the body after removal from the mould.
