Abstract

A window shade arrangement for a motor vehicle is provided that contains a housing in which a winding shaft is rotatably supported. A strip shaped shade element is fixed on the winding shaft. The cover of the window shade housing is formed by a spring housing. A coil spring for tensioning the winding shaft in the wind up direction of the strip shaped shade is seated in the spring housing. The spring housing, the spring seated therein and a coupling shaft form a preassembled unit.
