ABSTRACT:
A tarpaulin bow cover system for vehicle such as lorries or trailers includes a number of U-shaped bow members which cover the width of a loading platform of the vehicle and for opening or closing the cover by means of rollers or roller trolleys can be displaced in the longitudinal direction of the loading platform along running or guide rails positioned along the two lateral sides of the loading platform. When the cover system is closed the bow members on their bow elements, which define an upper limit, support a tarpaulin which covers the loading platform or the loading area of the vehicle. A first terminal bow member is immovably fixed to a face end of the loading platform and a second mobile terminal bow member is assigned to at least one fixing or locking device which is positioned at the other end of the loading platform. At least one U-shaped auxiliary bow member, which can be pivoted in a limited angular area about an axis of articulation parallel to the plane of the bow member, is arranged at the level of the bow member and the length of the legs of the auxiliary bow member is greater than the distance between the axis of articulation and the bow element of the corresponding bow member.
