Abstract
Movable sun visor (10) which is supported in a carriage shape via front and rear pair of bearing points (12, 13) in lateral guide grooves. The length and the curvature pattern of the guide grooves is selected such that the sun visor (10) can be rapidly transferred from the out-of-use position to the in-use position. However, a shock effect on the drive can be caused thereby. It is therefore proposed that the guide curve for the front pair of bearing points (12) has an S-shaped course, the guide curve has a convex curvature in the first path segments and a concave curvature in the last path segments, and the guide curve for the rear pair of bearing points (13) has a convex curvature over the entire length of the curve.
