Definitions

  • the present invention relates to a bumper assembly for a motor vehicle.
  • Bumpers and radiator grilles have previously been generally considered, developed and used as separate components.
  • the bumper is usually mounted on a corresponding motor vehicle and only then installed the grille as a separate component on the bumper.
  • the radiator grille has hitherto consisted of a visually high-quality material, since it significantly contributes to the appearance of the corresponding motor vehicle due to its hitherto known structure and installation position.
  • the material from which the grille is to be made must have sufficiently high UV resistance and physical properties due to the grille being exposed to environmental effects such as sunlight and other weather conditions. This entails that the material from which the grille is to be made is generally a high quality and usually expensive material, such as ASA.
  • the procedure of mounting the bumper and the grille as separate components requires that the behavior th of the components in a so-called crash case is usually not homogeneous. This means that in the event of a collision, the bumper and the radiator grille installed in it react differently to the impact caused by the impact.
  • bumper grille would respond as homogeneously as possible to impinging loads. This means that a vertical plane formed by the bumper and grille should be deformed as evenly as possible in the event of an impact in the vehicle longitudinal direction. According to the current state of the art, however, due to the mounting of the radiator grille relative to the bumper tilting of the radiator grille is to be expected in an impact on the assembly bumper grille. This entails the risk of an impermissibly large increase in the knee flexion angle and the shear.
  • bumper grille assemblies now known in a mid-range of the structure tend to "sag" after a period of service life, meaning that the bumper grille assembly gradually descends due to material creep in the vertical plane.
  • the bumper assembly comprises a bumper and a grille, which is connected as an integral part of the bumper with this.
  • the radiator grille has a base body and a trim part, the base body forming at least one first connection with the fender on a side of the bumper facing the motor vehicle and the trim part forming at least one second connection with the fender on a side of the bumper facing away from the motor vehicle in that the radiator grille and the bumper together form a sandwich structure at least in a region of the connections.
  • the bumper assembly sandwich structure or sandwich construction results for the bumper assembly according to the invention a stiffening associated with improved pedestrian protection performance. Further, by the stiffening achieved by the sandwich structure, material creep mentioned in explanation of the prior art can largely be avoided in a middle region of the bumper due to its own weight.
  • the degree of stiffening and the degree of material creep prevention is dependent upon the size of the region of the joints in which the radiator grille and the bumper together form such a sandwich structure.
  • the sandwich structure in a region of the connections a composite construction between the grille and bumper is realized, wherein components of the radiator grill, namely the main body and the trim part from different directions, ie from the front or from the side facing away from the motor vehicle and from behind or the motor vehicle side facing are mounted on the bumper.
  • the bumper of the radiator grille or of its component enclosed As a rule, the grille will be mounted in a central area of the bumper.
  • the realized composite construction or the associated sandwich structure of the bumper arrangement in a region of the connections between the radiator grille and the bumper ensures that the bumper and the radiator grille reinforce each other.
  • the bumper arrangement according to the invention to connect the radiator grille at a central region of the bumper with the bumper.
  • the base body can be used for a plurality of motor vehicle variants, since the base body, due to the illustrated assembly, can be separated from the side facing away from the motor vehicle, ie. H. the outside of the motor vehicle is not visible, thereby making it possible to use it in a plurality of motor vehicle variants having an outwardly different appearance.
  • the base body is made of an impact-resistant material.
  • the impact-resistant material can be inexpensive; in particular, it may be a recyclate. Thus, product costs can be reduced by optimizing the use of materials.
  • the base body which is not visible from the outside and therefore does not have to take into account the visual appearance, nor is it exposed to weather conditions, therefore only needs to meet reduced requirements with respect to its surface quality.
  • the covering part is made of a UV-stabilized material.
  • the trim part which is arranged on a side facing away from the motor vehicle and thus visible to the outside of the bumper, contributes to the appearance of the motor vehicle on the one hand and on the other hand must withstand all conceivable weather conditions. Because of this, a UV-stabilized material should be used here, which should also have some specific optical and physical properties.
  • the trim part is designed as a motor vehicle type specific part. This means that the trim part can be made variant-forming in order to be able to characterize, inter alia, a variant of a motor vehicle.
  • the grille is connected to the bumper by means of suitable clip connections or catches.
  • the clip connections and / or locks can be designed in any suitable form.
  • the base body on an underside of the base body and the trim part on an underside of the trim part are each connected to an upper side of the bumper and the trim part is connected to an upper side of the trim part to the main body at an upper side of the base body.
  • trim part is also connected to the base body by suitable clip connections and / or latching.
  • the bumper is a front bumper for a motor vehicle.
  • a bumper arrangement according to the invention makes it possible for more cost-effective materials, such as, for example, a recycled material, to be used in overlapping regions of the radiator grille with adjacent components, such as, for example, a lacquered outer skin, large-area chrome applications and an engine hood of the motor vehicle.
  • This is made possible in particular by the bipartite nature of the radiator grille used in the bumper arrangement according to the invention.
  • This two-part design of the radiator grill can thus optimize the use of materials and thus the product costs. All visible parts are usually made of a UV-stabilized, usually expensive material, whereas a mounted from the back of the component, namely the body of the radiator grill can be made of an impact-resistant cheaper material that has to meet only reduced requirements in terms of its surface quality.
  • offers the use of a recyclate. Further advantages and embodiments of the invention will become apparent from the description of the accompanying drawings.

  • the cowling 5 is mounted from the front to the central region Z of the bumper 2. Accordingly, the covering part 5 is also visible from the outside, which means that, on the one hand, it has to meet the desired optical properties and, on the other hand, it should withstand a large number of external influences, such as weather conditions. For this reason, the trim part 5 is usually made of a kann searchen material which has sufficient UV stability and certain physical and optical properties.

  • the material used can be optimized by the two-part design of the radiator grill 3, namely in the form of the main body 4 and the trim part 5.

Here, for example, offers the use of a so-called. Recyclate.
