    Detailed description of the inventionClamp and chafing damage to cable harness and / or pipe 5 usually occurs when a bumper beam 1or another type of beam 1 for motor vehicles shall be fitted to a part of the motor vehicle,such as mounting a beam 1 on the motor vehicle chassis. The motor vehicle chassis can on sometypes of motor vehicles (frame-built ones) also include a frame structure, why1015202530the bumper beam 1 in this case is mounted on the frame of the motor vehicle. Beams 1 can also be onepart of the motor vehicle chassis and / or frame construction, which will be well understood by those skilled in the art.
    The inventor has drawn attention to the fact that the damage to the cable trunk and / or pipe almostoccurs exclusively at the area closest to the fastening means 3 with which the bumper beamor other types of beams 1 are mounted on the chassis of the motor vehicle. In the case of Bumperbeams 1, these can be mounted directly on the chassis of the motor vehicle or indirectly by means of a orfl your bumper brackets 7, which are arranged between the bumper beam 1 and the chassis.
    In order to solve the above-mentioned and related problems, the invention therefore relates to abeam 1 for a motor vehicle. The beam has at least one contact surface 2 for at least one associatedfastening means 3 with which the bumper beam 1 is arranged to be mounted at a part of amotor vehicles, such as the chassis of the motor vehicle, so that at least a part of the contact surface 2 comesin contact with the motor vehicle chassis. Furthermore, the beam 1 comprises at least one protective element 4arranged at the contact surface 2 for protecting at least one cable trunk and / or a pipe 5 arrangedat the beam 1.
    The protective element 4 extends substantially along a part of the cable stem and / orthe extent of the tube 5, and comprises at least one wall 6 arranged between the fastening means 3 andthe cable stem and / or the tube 5, against which wall 6 the cable stem and / or the tube 5 is intendedto be locked.
    Figure 3-5 shows a first embodiment of a part of a bumper beam 1 for mounting at the fronton a motor vehicle, such as a truck. Figures 3 and 4 show the bumper beam 1 in perspective viewseen from behind. The bumper beam in this example comprises two fastening means 3 in the form of twolarger mounting holes for receiving mounting bolt, and a third mounting member 3 inin the form of a smaller mounting hole for receiving a guide pin with which the bumper beam1 is guided into the correct position when mounting it on the motor vehicle chassis. Other types offastening means 3 can for instance be recesses, bolts, and guide pins, which will be well understood bythe professional.
    Furthermore, the bumper beam 1 has a contact surface / contact area 2, which is the surface / areaclosest around the fastening means 3 and can be said to constitute the critical area onthe bumper beam 1 where the damage usually occurs when mounting the bumper beam 1 on1015202530chassis. The contact surface 2 encloses one or more of your fasteners 3 and will be in immediatelyor indirect mechanical contact with the chassis of the motor vehicle when the bumper beam 1 ismounted on the same.
    If the bumper beam 1 is mounted on the motor vehicle chassis by means of bumper brackets 7(indirect contact), as shown in Figure 5, the contact surface 2 will be the surrounding surfacethe fastening means 3 which abut against this bumper bracket, i.e. area of the Bumperthe beam 1 under the bumper bracket 7 shown in figure 5. The bumper bracket 7 then functions as aintermediate fitting element between the bumper beam 1 and the chassis of the motor vehicle sothat different models of bumper beams 1 can be mounted on one and the same chassis, or viceVGYSÛ ..
    To reduce or minimize damage to cable harness and / or pipe 5 has a local recessarranged on the lower part of the bumper beam 1 below the fastening means as shown inFigure 3-5. The local recess acts as a protective element 4 for the cable trunkand / or the tube 5 and extends substantially along a part of the cable stem and / orthe extent of the tube 5 and has been given rounded shapes in the embodiments in Figures 3-5avoiding, for example, abrasions.
    Furthermore, the protective element 4 comprises a wall 6 (see Figures 4 and 5) which is arranged betweenthe fastening means 3 and the cable stem and / or the tube 5. The purpose of the wall 6 is to lockthe cable stem and / or the tube 5 so that these cannot be moved or moved, at or aftermounting, closer to the fastening means 3 than the distance between the wall 6 and the fasteningmeans 3. This reduces or eliminates the risk of damage to the cable trunk and / or pipe 5when the bumper beam 1 is mounted on the chassis of the motor vehicle and / or abrasions occurafter mounting.
    The wall 6 can therefore be said to limit the contact surface 2 in the direction from the fastening means towardsthe part of the bumper beam 1 where the cable stem and / or the tube 5 is arranged, i.e. delimitsthe spread of the contact surface 2 in said direction. This separates the contact surface 2 and that part of itthe bumper beam 1 on which the cable stem and / or the pipe 5 is arranged, therefore damagecable harness and / or pipe 5 is avoided or completely eliminated. The wall 6 is for this reason according toan embodiment substantially arranged perpendicular to the area of propagation of the contact surface 2bumper beam 1, as shown in Figure 3-5.1015202530According to an embodiment, the local recess is between 5-50 mm deep, preferably 15-45 mm deep, between 150-350 mm long (horizontal), preferably 200-300 mm long, andbetween 15-45 mm high (vertical), preferably 25-35 mm high. In addition, the distance isbetween the recess and the nearest fastener 3 between 5-25 mm andpreferably 10-20 mm.
    In the embodiments in Figures 3-5, the bumper beam 1 also has two hole recesses 10comprising holes for receiving each suspension member 8 with which the cable stemand / or the tube 5 is held in place in the recess. According to a further embodiment,the suspension means 8 a vertically arranged stop tongue for completely or partially enclosingthe cable stem and / or the tube 5. Such a suspension member 8 is shown in Figures 5-7 where itvertically arranged stop tongue in this example is in the form of a bent / bent sheet metal portion.
    Furthermore, it should be noted that the hole recess 10 also limits the spread of the contact surface 2,which is clearly shown in the embodiment of Figure 4.
    In Figures 3-5, the suspension means 8 in the form of supporting brackets are mounted in the holes.
    These brackets can be, a spring steel bent / bent cable holder, for mounting in the holesfor supporting (fixing) cable harness and / or pipe 5, but also be in the form ofrubber staples mounted in the holes. To further fix the cable stem and / or tube 5 inthe local recess can also be used with cable ties to hold themthe suspension means 8.
    Figures 6 and 7 show an embodiment of a bumper beam 1 without hole recesses 10 as inembodiments in Figure 3-5. Instead, two brackets are set up in the recess for supportof cable harness and / or pipe 5. These can preferably consist of one from the bumper beam 1cut out and bent / bent piece of sheet metal, e.g. in the case that the bumper beam 1 is made of two orseveral welded plates. In this embodiment, the bumper beam 1 is joinedby welding a front and a rear plate, the rear plate having foamand bent sheet metal pieces for the formation of said brackets longer as suspension means 8.
    According to such an embodiment, it is the rear plate that will be mounted onmotor vehicle chassis. However, brackets can also be made of foam and bent / bentpiece of sheet metal from bumper beams 1 consisting of only one sheet.1015202530A further embodiment of the invention is shown in Figures 8 and 9. In this embodiment ofa bumper beam 1, the protective element 4 consists of a portion projecting on the bumper beam 1 inin the form of a protective lip without recess. The protective lip comprises a wall 6 against whichthe cable stem and / or the tube 5 is intended to be locked, whereby the protective lip can be made ofone from the bumper beam 1 cut out and bent / bent sheet. Figure 8 shows the embodimentsillustrated with cable harness and / or pipe 5, and Figure 9 shows the embodiments illustrated withoutsaid cable stem and / or tube 5. A protective lip can also be manufactured by one or fl erapieces of sheet metal with a suitable protective shape are welded to the bumper beam 1. Cable stem and / or pipe5 can for instance be fastened to the protective element 4 by means of cable ties, straps or the likearrangement.
    The protective lip shown in Figures 8 and 9 is between 100-200 mm long, preferably 125-175 mmlong, and protrudes about 15-35 mm, preferably 20-30 mm from the bumper beam 1. Furtherit is set up at a distance between 5-25 mm from the nearest fastener 3 ithe figures, preferably between 10-20 mm from the fastening means 3.
    According to a further embodiment of the invention, the bumper beam 1 comprises one or threeprotective element 4 consisting of a combination of recesses and protective lips.
    Figures 10 and 11 show, in rear view, two different embodiments of a bumper beam 1according to the invention. The two bumper beams 1 in said figures comprise two contact surfaces 2placed at a mutual distance from each other and preferably at each otherend portion of the bumper beam 1.
