"Bumper fitting_an experience vehicles"

The innovation befa.sst to a device for accommodating impact loads in particular .Kraftfahrzeugen · It is an object _s improved protection for ,, to achieve! Vehicle's bodywork and in particular for the occupants »

The hiring is based on the bumper assemblies known per se on motor vehicles * It is characterized by a hollow profile made of elastic, especially cushioning. Material like grummi, art " fabric or the like that are inserted into a retaining profile, preferably made of metal, along this retaining profile for attachment can a

The new bumper arrangement has the advantage that it is lightweight can be mounted «it is» as explained «· laterally in the profile of the retaining element pushed in »If the elastic profile is defective due to a collision, it can easily be replaced» The new one The bumper arrangement is on both the front and the rear of the vehicle to attach tools »Retrofitting is also possible»

Since the holding profile and said elastic profile a certain weight own ₅ and since the corresponding compounds are relatively deep ^ x * rird the center of gravity of the vehicle in the direction of the roadway shifted Hereby, the well-known door sections of an assembly of the vehicle center of gravity in the Fähe the roadway achieved «Bs should be pointed out, for example, to the reduced risk of skidding

In a further embodiment of the control is the retaining profile essentially a C-profile - seen from the center of the car is open to the front or back * This makes a cheap one Gate suspension for the sliding in of the elas described in more detail above « tables with a hollow profile

The Ealteprofil may further be mounted on support members such as rods or profile bar and with the interposition of a ICegelfedex the vehicle * The conical spring serves for receiving relationship ** as Ter-destruction that energy _9, the hollow by the elastic profile and / or the O-jprofil not destroyed - was _e - Instead of the above-mentioned conical spring, one or more rubber buffers can be placed between fixed parts of the vehicle and those parts _? which are acted upon by the bumper ^ are switched o

To further stiffen the retaining profile, which is essentially designed as a C profile, this C profile is parallel in one plane curved to the road surface * To increase the resistance «-, moments, the retaining profile can also be provided with webs and, in particular, be designed in a honeycomb shape *

Further details of the firing are an illustrative example to be found ^ the following is described in more detail with the help of two figures «

Figure 1 shows schematically the front half of a motor vehicle *

FIG. 2 shows the details according to a section II- »II of FIG of the new bumper

On the vehicle body 10, the bumper 11 is supported by holding members 12 and 13 attached, \.

Such a holding member is shown in detail in FIG.

Starting from the left in FIG. 2, the bumper is made up of an elastic profile I4 * which encloses a cavity I5. The cavity has a special suspension and damping characteristic that can be adapted to the size of the vehicle or the performance of the vehicle. The hollow profile I4 is laterally inserted into the C-shaped profile 16 "Lateral insertion is to be understood ₉ as the profile I4 τ.oh one end face. 27 of the profile 16 in the direction of the arrow 28 "see FIG. 1", the parts 17 and -18 <- see FIG with elastic dampening & m material,

position information 29s can also be filled in or webs can be arranged which, together with the Q-profile 16, result in a honeycomb structure * over the part 20 and the bolt 21, the bumper is «■■ - catcher attached to the connecting rod 22, preferably detachably»

A stop 23 is fastened to the connecting rod 22 «Between 23 and the part 24 ₉ which is firmly connected to the vehicle ₉ there is an Eegelfeder 25® Instead of the Eegelfeder a rubber buffer between 23 and 24 *

The Peder characteristics of the elastic hollow body 14? possibly of the second elastic body 29 and finally the conical spring are coordinated so that you see a progressive suspension resultsa With slight bumps it is deformed due to the hollow design only the body I4 · Deformed when pushed harder also the body 22 and possibly the spring 25 *

The body I4 can e be provided in area 26 with a decoration means, for example a metalized plastic strip (decor strip) *
