Definitions

  • the invention relates to a vehicle restraint system according to the features in the preamble of claim 1.
  • a protective barrier consists of juxtaposed, a trapezoidal longitudinal channel and flat legs comprehensive guard rails. Between the guard rail and the posts trapezoidal reinforcing profiles with diverging legs are incorporated in cross section. The webs of the stiffening profiles are located on the protective plank strand facing legs of the posts. The ends of the diverging legs grasp in the throats of the guard rails, which are formed by the flat legs and the ends of the flat legs bent flanges.
  • the vehicle restraint system described above is intended in particular to be used along roads lined with obstacles, in particular trees, so that an impacting motor vehicle is reliably deflected or no bagging occurs.
  • the prior art also includes the vehicle restraint system of DE 201 06 675 U1 ,
  • a stiffening of a protective barrier strand takes place in that reinforcing profiles are incorporated between the protective barrier strand and fixed to the ground post.
  • These reinforcing profiles have a C-shaped cross-section, wherein the mutually facing flanges of the reinforcing profiles bear against the inner sides of the flat limbs of the guard rails and are screwed thereto.
  • the effective range W is a characteristic variable for the evaluation of a vehicle restraint system.
  • the effective range W is the distance between the traffic-facing side of the vehicle restraint system and the maximum dynamic lateral position of each essential part of the vehicle restraint system.
  • the invention is - based on the prior art - the object of the restraint of a vehicle restraint system generic type while avoiding bag formation to further improve.
  • the ends of the legs of the reinforcing profiles facing away from each other are provided on the inner sides of the flat leg of the guard rails fitting flanges.
  • the flat legs are based on a large area at a comparatively large vertical distance from each other having flanges of the reinforcing profiles.
  • the guard rails overlap in the area of a post and are screwed here at least indirectly with the posts and their flanks with the flanges of the reinforcing profiles under fixation of the reinforcing profiles on the bottoms of their longitudinal channels. In this way, care is taken that the reinforcing profiles can not spread inadmissible in a vehicle crash and thus affect the functionality of the vehicle restraint system.
  • the overlapping areas of the reinforcing profiles are provided in the areas between two successive posts and thus arranged offset in the longitudinal direction of the vehicle restraint system to the overlapping areas of the protective barriers.
  • the reinforcing profiles are bolted together over their bottoms and over their legs. In this way, sufficient longitudinal, transverse and torsional stiffness is given even in the overlapping areas of the reinforcing profiles.
  • the invention now makes it possible to bring about targeted stiffening of a vehicle restraint system in special danger spots, for example in the area of trees. An inadmissible bagging of the protective barrier string is prevented. The occupants of a vehicle are better protected. But too much damage to a vehicle involved in a crash vehicle are avoided.
  • the vehicle restraint system achieves the containment stage H2 and an effective range W5 with an ASI value (Acceleration Security Index) of less than 1.
  • the reinforcing profiles can be provided with a row of holes, in the factory or manufacturer side every 30 cm to 40 cm a hole is provided.
  • the bores can also be produced on site at the construction site in order to fix the reinforcement profiles to the posts.
  • the posts can then according to local conditions in the ground be rammed, for example, to avoid roots or stones in the ground.
  • the spacers can be made of steel or plastic.
  • the stoppage of the vehicle restraint system is further improved with the features of claim 5.
  • the training according to the invention has to Foge that according to claim 6, the protective barriers can be made thinner than the reinforcing profiles.
  • the larger game of bolts in the holes (claim 7) can contribute to the reduction of energy in an impact.
  • the mounting relief of the vehicle restraint system serve the features of claim 8.
  • the posts have a sigmoidal cross-section.
  • Holes for receiving a mounting tool are provided in the legs of the posts or in the sections of the spacers facing the guardrails.
  • This assembly tool can consist of a simple round rod, which is inserted through the holes during assembly of the reinforcing profiles.
  • the assembly tool protrudes beyond the posts or the spacers so that the reinforcing profiles can first be threaded onto these round bars without the fitters manually setting the reinforcing profiles at a specific height during the further assembly have to hold.
  • the successive reinforcing profiles can then be screwed together.
  • the guardrails are bolted to the posts or the spacers and the flanges of the reinforcing profiles.
  • FIGS. 1 and 2 denotes a vehicle restraint system, which is used in particular where along the roadways 2 obstacles, eg in the form of trees B, are present in the immediate vicinity.
  • a tree B is in the FIG. 9 indicated.
  • the vehicle restraint system 1 comprises at first at a distance of, for example, 2 m at the bottom 3 fixed, in particular rammed into the ground 3, post 4 with a sigma-shaped cross section.
  • post 4 with a sigma-shaped cross section.
  • FIG. 8 can recognize, extend the legs 5 of the posts 4 largely parallel to the roadway.
  • the distance between the posts 4 may be less than 2 m in the area of trees B or in other problem areas.
  • a guard rail 7 from each other with their end sections juxtaposed guard rails 8.
  • the guard rails 8 have the embodiment a length of 4 m. Their overlapping areas 9 are in the area of a post 4.
  • the guard rails 8 a trapezoidal longitudinal channel 10, which is bounded by a bottom 11 and two in the direction of the lane 2 diverging legs 12. With the legs 12 upwardly and downwardly directed flat leg 13 are connected, which are bounded at the ends by short flanges 14, which are directed away from the roadway 2.
  • FIGS. 5 to 7 From the FIGS. 5 to 7 is also apparent that in the bottoms 11 of the longitudinal channels 10 and in the flat legs 13 holes 15 for the passage of from FIG. 3 recognizable bolt 16 are provided. In addition, 15 elongated holes 18 in the floors 11 extend between the holes.
  • FIGS. 1 to 4 show that between the guard rail 7 and the post 4 in cross-section trapezoidal reinforcing profiles 19 are incorporated with in the direction of the guard rails 8 diverging legs 20. End of the legs 20 are provided facing away from each other flanges 21. The flanges 21 are located on the inner sides 33 of the flat legs 13 FIG. 5 recognize that at one end of each reinforcing profile 19, ie in the overlapping region 22 of two reinforcing profiles 19, a cranked portion 23 is provided. The size of the offset is equal to the wall thickness of the reinforcing profiles 19 dimensioned.
  • the overlapping areas 22 of the reinforcing profiles 19 are, in particular the Figures 2 . 5 and 6 can recognize each in the area between two consecutive posts 4.
  • a plurality of holes 25 and in the legs 20 each have a bore 26 for the passage of from FIGS. 2 to 6 recognizable bolt 27 is provided.
  • guard rails 8 are set by means of predetermined breaking screws 16 to the post 4, wherein the Sollbruchschrauben16 oblong holes 18 in the floors 11 of the guard rails 8, spacers 32 between the floors 11 and the bottoms 24 of the reinforcing profiles 19 and holes in the legs 5 of the posts 4 enforce.
  • the flanges 21 of the reinforcing profiles 19 are connected via bolts 34 with flat-curved heads 17 with the flat legs 13.
  • the assembly tools 29 in the form of round rods can also be used.
  • FIG. 9 shows a vehicle restraint system 1 of a guard rail 7, reinforcing profiles 19 and post 4, which is preferably arranged in the region of a tree B. It can be seen that the posts 4 in the vicinity of the tree B have a smaller distance from each other than in more remote from the tree B sections of the protective barrier 7. For this purpose, in the floors 24 of the reinforcing profiles 19 a plurality of spaced apart holes 35 are provided , over which and bolts the reinforcing profiles 19 are attached to the post 4.
  • FIG. 10 an embodiment is illustrated in which the guard rails 8 and the reinforcing profiles 19 on the one hand on the flange legs 13 and the flanges 21 with each other and on the other hand held by spacers 32 spaced floors 11, 24 by means of bolts 16 and nuts 27 both together and with the post 4 fixed spacers 36 are connected.
  • the thickness D of the reinforcing profiles 19 is greater than the thickness D 1 of the guard rails 8 dimensioned.
  • the bolts 16 pass through holes 15, 25, 30 in the flange legs 13, in the flanges 21 and in the floors 11, 24 with play.
