are approximately located in a plane e v which extends approximately vertically wherein the term approximately vertically comprises an angular deviation of plus minus 30 u00b0 in relation to the exactly vertical direction the plane e v is located transversely to a plane e h in which the cover parts 60 and 62 are located in the functional position of the wind stop device wherein the plane e h extends approximately parallel to the belt line 14 of the body 10 in the section 18 in order to fold the inventive wind stop device together the wind blocker 12 and the cover 16 may be folded towards one another about the connection folding axis 90 such that a rear side 92 of the wind blocker 12 is located on an upper side 94 of the cover 16 wherein for this purpose no folding about either the wind blocker folding axis 44 or the cover folding axis 64 need have taken place fig3 moreover as illustrated in fig4 it is possible to fold one of the wind blocker parts 50 or 52 for example the wind blocker part 52 about the wind blocker folding axis 44 such that a front side 96 of the wind blocker part 52 is located on a front side 98 of the wind blocker part 50 as illustrated in fig5 in order to configure this folding as simply as possible the web of flat material 42 is located each time in.
