<p>The longitudinal strips (12, 13) of the rail are applied to the side of the support post (11) which is facing the roadway and the web members (15) are secured on the roadway side to the longitudinal strips (12, 13). The web members (15) - oval-sectioned tubes arranged with the major cross-sectional axis at right angles to the rail - are so clamped by internal retaining elements (151) to the longitudinal strips (12, 13), that, when undergoing a determined lateral impact force, they can pivot around the retaining elements (151) against the longitudinal strips (12, 13). Thus the web members (15) can lie upon another like tiles on a roof. A safety cable (16) can be inserted in each of both the lower and the upper longitudinal strips (13, 12), whereby eyelet screws (142, 144) clamp the cable (16) against strip securing elements (14) and the latter clamp the longitudinal strip (12, 13) against the support posts (11).</p> |
