ABSTRACT:
The sunshade has several carrying bars (1) which can be spread in radially directed manner away from a central headpiece and several screening surface structures (17), which are in each case fixed between two carrying bars (1). In order to prevent a sag of the surface structure (17) in the case of incomplete spreading of the sunshade and in order to permit an easy closure to give a compact shape, it is made from pleated awning material, which in the relaxed state and with the sunshade collapsed assumes a pointed, zig-zag cross-sectional shape. In addition, with spring pulls cords (35) extend between the carrying bars (1) in the circumferential direction of the sunshade. Stiff envelope surfaces (14, 15) provided on either side of the carrying bars (1) give a columnar shape to the compact, collapsed sunshade.
