A tensioning unit for pull elements such as cables includes a tensioning element and a spring element, wherein the tensioning element and the spring element are arranged in a row, a length of the tensioning element is shortened in such a manner that the tensioning element has a pretension, the pretension is designed to increase the length of the tensioning element, and wherein the direction of the length enlargement of the tensioning element is directed away from the spring element.

A support arm having a proximate support arm segment, a distal support arm segment, a hinge system; and at least one rotation limit stop secured to the hinge system to limit the extent of angular motion of the proximate support arm segment, the distal support arm segment or both, with respect to the hinge system. The rotation limit stop includes a first stop component and a second stop component slidable with respect to the first stop component. When the second stop component encounters a contact point on one of the support arm segments, the angular motion of the arm segment with respect to the hinge system is at a maximum. The second stop component can be secured in a plurality of positions with respect to the first stop component by an adjustment component.

The present invention relates to a windscreen wiper strip support and a windscreen wiper blade having the windscreen wiper strip support. The windscreen wiper strip support includes a longitudinal slot for housing a windscreen wiper strip. The windscreen wiper strip support has a back plate, a plurality of first lugs and a plurality of second lugs. The longitudinal slot is formed by the space encircled by the back plate, the plurality of first lugs and the plurality of second lugs. The back plate, the plurality of first lugs and the plurality of second lugs are all made of a metallic material to ensure that the entire windscreen wiper strip support has better strength and the production cost is reduced.

A floating joint includes a driving side coupling portion and a driven side coupling portion serving as first and second connections. A pressure adjusting structure in the floating joint is provided between the bottom surface exposed region of the spherical portion for contact and the bottom surface facing region of a fixing ring without a gap, and has elasticity. Therefore, the floating joint relatively firmly maintains the one-side spherical contact relationship, in which the top region of the spherical portion for contact contacts a part of the bottom surface portion of the frame body by the elastic force of the pressure adjusting structure.
