Abstract
A protection device (5a) for motorcyclists, adapted to be secured to a road safety barrier (1) with a plurality of poles (3) regularly spaced out, the protection device (5a) including a longitudinal beam (6a) and a spacer (7a) extending longitudinally alongside the rear side of at least one part of the beam (6a) and adapted to be secured to the poles, wherein the beam (6a) and the spacer (7a) are assembled together so as to define, in the part of the beam, a longitudinal damping volume (V) with a closed cross-section.
Claims31
A protection device for a motorcyclist, adapted to be secured to a road safety barrier with a plurality of poles regularly spaced out, the protection device comprising:
- a longitudinal beam, wherein the beam is inclined relative to a pole axis of the poles, and wherein the beam includes upper and lower end parts;
- and
- a spacer extending longitudinally all along a rear side of the beam and adapted to be secured to a respective one of the poles, the beam and the spacer assembled together so as to define a longitudinal damping volume with a closed cross-section, wherein the spacer includes:
- a central fastening section fastened to the poles, and
- a superior leg and an inferior leg extending from the central fastening section and each having an open end fastened to the upper and lower end parts of the beam, respectively, the inferior leg and the superior leg being at an angle a between 60° and 100° and the inferior leg and the central fastening section being at an angle B between 105° and 145°.
A kit for the assembling of a protection device for a motorcyclist, adapted to be secured to a road safety barrier with a plurality of poles regularly spaced out, the kit comprising:
- a first profiled sheet forming a longitudinal beam, wherein the beam is inclined relative to a pole axis of the poles, and wherein the beam includes upper and lower end parts;
- a second profiled sheet forming a spacer, the spacer extending longitudinally all along a rear side of the beam and adapted to be secured to a respective one of the poles
- wherein the beam and the spacer are adapted to be assembled together, so as to define a longitudinal damping volume with a closed cross-section,
- wherein the spacer includes a central fastening section fastened to the poles from which extend a superior and an inferior leg with open ends that are adapted to be fastened to the upper and lower end parts of the beam, respectively, the inferior leg and the superior leg being at an angle a between 60° and 100° and the inferior leg and the central fastening section being at an angle B between 105° and 145°.
