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.
Claims14
A movable sun visor consisting of a sun visor body, which is supported in a carriage in lateral side guide curves via a rear pair of bearing points which are oppositely formed at the lateral edges in the area of a rear edge of the sun visor body, and a front pair of bearing points, which are oppositely formed at the lateral edges between the rear pair of bearing points and a front edge of the sun visor body, there being two equal guide curves for the front pair of bearing points which differ in the pattern of curvature of and being longer than two equal guide curves which are provided for the rear pair of bearing points, and the first pair of guide curves (A) for the front pair of bearing points follows an S-shaped course with a convex curvature in a first set of path segments (A0, A1 and A2), and a concave curvature in a second set of path segments (A3, A4, A5 and A6), and the second pair of the guide curves (B) for the rear pair of bearing points has a convex curvature over the entire length of the curve, wherein the greatest curvature of the guide curve (B) for the rear pair of bearing points is formed in a set of path segments (B3, B4, B5 and B6), which correspond to the second set of path segments (A3, A4, A5 and A6) on the guide curve (A) for the front pair of bearing points.
Movable sun visor consisting of a sun visor body, which is supported in a carriage shape in lateral side guide curves via a rear pair of bearing points, the two bearing points of which are formed opposite at the lateral edges in the area of the rear edge of the sun visor body, and a front pair of bearing points, the two bearing points of which are formed opposite at the lateral edges between the rear pair of bearing points and the front edge of the sun visor body, the two equal guide curves for the bearing points of the front pair of bearing points differing in the pattern of curvature and the length of the two equal guide curves for the bearing points of the rear pair of bearing points, and the guide curve for the front pair of bearing points being longer than the guide curve for the rear pair of bearing points, characterised in that the guide curve (A) for the bearing points (12) of the front pair of bearing points follows an S-shaped course, that the guide curve (a) has a convex curvature in the path segments (A0, A1 and A2), that the guide curve (A) has a concave curvature in the path segments (A3, A4, A5 to A6), that the guide curve (B) for the bearing points (13) of the rear pair of bearing points has a convex curvature over the entire length of the curve, and that the greatest curvature of the guide curve (B) is formed in the path segments (B3, B4, B5 to B6), which correspond to the associated path segments (A3, A4, A5 to A6) on the guide curve (A).
