Windshield for two-wheelers, especially motorcycles

The present innovation relates to a windshield for two-wheelers, in particular for motorcycles according to the preamble of claim 1.

Most of today's two-wheelers, especially motorcycles, are equipped with windshields. Depending on their shape and size, windshields are designed to keep the wind and rain away from the rider. Some windshields are positioned within the rider's field of vision, which offers relatively good wind and weather protection. However, with such windshields, the rider has to look through the windshield, which can impair driving safety, especially in rain and when the windshield is dirty. Sportier motorcycles usually have lower windshields. The rider can look over these windshields, but the disadvantage is that they offer relatively little wind and weather protection.

Conventional windshields usually have a straight or slightly convex curved upper edge.

The aim of the innovation is to create a windshield for two-wheelers, especially motorcycles, that offers good wind and weather protection and does not or hardly impair the driver's vision.

This problem is solved by the features of claim 1. Advantageous embodiments and further developments of the innovation can be found in the subclaims.

The innovation is based on a windshield for two-wheelers, particularly for motorcycles, which has a front, lower edge and side edges that merge into an upper edge that acts as a flow separation edge. The core of the innovation consists of a "retracted" upper edge. To be more specific, the distance between a central area of the upper edge and the lower edge is smaller than the distance between the outer areas of the upper edge and the lower edge.

Preferably, the upper edge has the shape of a concave indentation in its central region.

According to a further development of the innovation, the windshield is dimensioned and arranged on a two-wheeler, particularly a motorcycle, in such a way that the driver can look at the road over the middle area of the upper edge of the windshield. This has the advantage that even if the windshield is dirty, the driver's view is not impaired.

The windshield is advantageously dimensioned and positioned on the two-wheeler or motorcycle in such a way that the outer areas of the upper edge of the windshield are raised to the height of the rider's shoulders. This has the advantage that the shoulders of the rider and the pillion passenger are protected from direct

Another advantage is that, compared to conventional windshields, the extremely annoying wind noise is significantly lower, as the driver's head is no longer in the so-called "shear layer". Overall, this results in significantly less "helmet excitation" as the flow in the helmet area is less turbulent than with conventional windshields. In other words, the helmet is not shaken as much by the wind flow when driving fast as it is with conventional windshields.

&iacgr;&ogr; In the following, the innovation is explained in more detail using an example in conjunction with the drawing. It shows:

seeks; and

Figure 2 shows the windshield of Figure 1 in frontal view.

Figure 1 shows a windshield 1 that has a front lower edge 2, side edges 3, 4 and an upper edge 5. The upper edge 5 functions as a flow separation edge. The upper edge 5 has a central region 6 and outer regions 7, 8. The outer regions 7, 8 merge into the side regions 3, 4.

It is essential that the distance a between the central region 6 of the upper edge and the lower edge 2 is smaller than the distance b between the outer regions 7 and 8 and the lower edge 2.

In the embodiment shown in Figures 1 and 2, the windshield 1 has the shape of a concave recess in its central region 6 of the upper edge 5. The recess provides a good view of the
