Abstract (en)
[origin: WO9936631A1] The guardrail (1) has a rail (5) connected to each post (3) by a spacer (13) and an energy dissipator (21), in which the spacer (13) carries two cam slots (27, 28) engaged by two pins (29, 30). The spacer (13) has a horizontal rib (20) located between the two slots (27, 28) and housed inside a rib (35) on the dissipator (21), which also has a further two horizontal ribs (33). The pins (29, 30) are of equal diameter and also engage two identical openings (11, 12) in a release body (41) movable telescopically inside the post (3). The openings (11, 12) are defined by two partitions (14, 49) which are sheared simultaneously by the pins (29, 30). And the guardrail (1) also has a wheel rail (50) carried by a spacer element (51) having an opening (56) of constant width, by which the spacer element slides over a pair of different-diameter bolts (57, 57') fitted to the post (3).
