<p>A roll-bar structural arrangement comprises symmetrical shells that can be mounted both inside and outside of the structure of the accessory, on both sides, without the need for separate parts. The shell (30) is attached to the extension (11) of the roll-bar, has ends fitted onto the central bar (10), and comprises two symmetrical parts (301) and (302) that form a single body and are joined together by a (non-depicted) male-female joint at the edges thereof. The shell (30) further has a hollow inside zone, a main segment (31) with a curvature that matches the curvature of the end portion of the central bar (10), and a secondary segment (32) that starts near the end of the main segment (31) and follows the curvature of the roll-bar extension (11), the ends of the main segment (31) and of the extension (32) having an aperture (33) with a cross-section that matches the diameter of the central bar (10) and of the extension (11) of the roll-bar, and a hollow inside zone in which a metallic structure (40) is arranged.</p> |
