[0032] This achieves the technical advantage that the angular, in particular right-angled, extension of the respective first and second guide elements relative to the direction of extension of the respective elongated hole ensures particularly effective guidance of the multi-leg link in the travel position.

[0033] In one embodiment, the guide elements are shaped as elevations, in particular ribs, rectangles, squares, triangles, and / or crescents, which are shaped in particular on a handlebar outer side of the respective handlebar leg.
