Abstract: A roof for vehicles, particularly convertibles: A roof material including an upper fabric layer, a lower fabric layer, a rubberizing layer arranged between the upper and lower fabric. Possibly a ceiling inner lining is arranged below the roof material. A protective layer is arranged on the lower fabric layer and/or on the top side of the ceiling inner lining. The protective layer consists of a cut resistant material of cut-proof fibers such as aromatic polyamide fibers, polyethylene fibers spun by the gel-spinning process, or glass fibers. A wire is in at least one system of the threads of the cut resistant material. A textile nonwoven layer is applied, by needling, on at least one side or both sides of the protective layer.

Abstract: A press-button device is provided that includes an upper part and lower part for fastening together fabric and other materials. The upper part has a hollow main part that includes a disc and a hollow central sleeve. Arranged within the main part are a compressible gripping connector within an outer gripping sleeve. A spring is positioned between the outer gripping sleeve and hollow central sleeve. A rivet secures the tops of the outer gripping sleeve and gripping connector to a button. A seal is provided between the button and the main part that protects the inside of the main part and permits axial movement of the button. The upper part also includes a plate positioned in the main part that carries a rigid annular sleeve with a conical-shaped interior surface that abuts against the end of the gripping connector. A washer secures the upper part to fabric or other material. The lower part includes a spherical undercut head for engaging the upper part gripping connector.
