Referring now to the drawings, wherein the same reference numerals are used throughout the various views to designate similar parts, the modified embodiments being distinguished by a ', ", etc., the structurally combined bumper covering generally designated by reference numeral 1, as illustrated in FIGS. 1 and 2, comprises a covering strip 2 and two lateral parts 3, and is secured at the body 5 of the vehicle outside of the bumper profile 6 by fastening means, for example, by screws 4. The covering strip 2 serves for bridging the gap 7 between the bumper, generally designated by reference numeral 6a, and the vehicle body 5. The lateral parts 3 extend around the sides of the body 5, and possess pocket-shaped bulges or convexities 9 for receiving the bumper ends 8 of the bumper 6a.
The bulges 9 can be suitably adapted to the body from a styling point of view to blend relatively smoothly with the sides of the body. In case of an impact on the bumper 6a, the bumper ends 8 can move more deeply into the pocket-shaped bulges 9 of the lateral parts, particularly by the use of a yielding support for the bumper 6a. At the same time, the covering strip 2 is able to slide along the upper leg 10 of the essentially U-shaped bumper profile 6.
The edges 11 of the covering 1 which face the bumper 6a may be rounded off or may be bevelled off in a sealing-lip shape. Additionally, fastening plates may be embedded into, vulcanized-in, or attached externally at the fastening places with respect to the fasteners, such as the screws 4, especially with bumper coverings of soft-elastic material, in order to assure a good fastening at the body 5.
A bumper covering generally designated by reference numeral 1' is illustrated in FIG. 3 which is arranged on the inside of the bumper profile 6.
FIG. 4 illustrates another embodiment with a flush arrangement of the covering generally designated by reference numeral 1" relative to the bumper 6.
FIG. 5 illustrates a cross-section through a lateral part 3 constructed with pocket-shaped bulges 9. The bumper ends 8 engage or extend at least partly into the bulges 9 during the normal construction of the bumper. Upon impact on the bumper 6a, the bumper ends 8 may be carried or moved more deeply into the pocket-shaped bulges 9, as may be seen by the dotted-chain line in FIG. 1.
FIG. 6 illustrates a cross-section taken along line IV--IV of FIG. 1. The bumper covering 1 extends in this portion by virtue of the lower part of the pocket-shaped bulge 9 about the bottom side 13 of the bumper profile 6. Again, the movement of the bumper toward the vehicle body upon impact enables the bumper profile 6 to extend more deeply into the bumper covering 1, and particularly the pocket-shaped bulges 9, as may be further seen by the dot-chain line in FIG. 6.
FIG. 7 illustrates a cross-sectional view of a preferred construction for the pocket-shaped bulge 9, as may be seen along line III--III of FIG. 1. In this construction, the pocket-shaped bulge 9 is of a generally C-shaped configurational profile with the opened portion of the profile facing the vehicle body 5. The pocket-shaped portion 9 is provided with edges 9a and 9b which extend atleast partially against the sides or walls of the body 5, and this lateral part is held against the body 5 by virtue of a holding plate 14 clamping the edges 9a and 9b.
The holding plate 14 is held toward the body 5 by means of the fastener 15, such as the bolt and nut member illustrated, which may preferably extend through a central zone of the holding plate 14. In addition, in order to distribute the holding forces, as well as to provide a firmer connection, a holding sleeve 16 is interposed between the holding plate 14 and the body 5 with the holding sleeve having flange-like arms extending along the sides of the body 5. Accordingly, fastening of the member 15 clamps the holding plate 14 and holding sleeve 16 together, thereby resulting in a clamping of the edges 9a and 9b of the pocket-like member 9 against the body 5.
This arrangement of the fastening of the pocket-shaped member 9 to the body 5 of the vehicle enables the bumper ends 8 to freely slide or move therein during impacts on the bumper without engaging the body wall 5. On the other hand, in the case of indirect impacts, the fastening of the pocket-shaped member 9 by its edges to the body wall, leaving an effectively hollow space, provides a cushion-like member that absorbs at least minor side impacts thereon to effectively diminish the impact without damage to the body wall. This is, of course, most effective if the lateral parts 3 of the bumper covering are of a soft-elastic material.
FIG. 8 illustrates a partial cross-section the clamping of the edges 9a and 9b of the pocket-shaped member 9 against the vehicle body 5'. In this case, the bolt and nut fastener 15' is designed to be fastened in a direction opposite to that illustrated in FIG. 7, which may be advantageously in accordance with different body constructions. Moreover, a clamping washer 17 may be utilized to distribute the holding forces of the fastener 15', and further, the holding plate 14' may have a recess at the fastener 15' so as to enable the plate 14' to be clamped against the walls of the vehicle body 5, thereby effecting a stronger connection resulting in the cushioning effect of the member 9.
FIG. 9 illustrates a further arrangement of the fastening of the edges 9a and 9b of the pocket-shaped member 9 to the vehicle body 5". In this regard, the ends of the edges 9a and 9b may protrude with a larger cross-section so as to receive configured recess ends of the holding plate 14", thereby effecting the clamping action of the edges 9a and 9b.
The construction of the bumper covering in accordance with the present invention is most advantageous in a bumper construction wherein the bumper 6a is secured to the vehicle fixed parts, such as the frame or cross-bearers, by means of a shock-absorber structure 18 having telescoping members 19 and 20. The member 19 of the shock absorber is fixed to the bumper 6a' through the fastening structure 21 which includes a flange-like member at the end of the member 19 having ends embedded into an elastic member 22 for cushioning vibrations of the bumper with respect to the shock absorber 18, and being assembled to the member 19 by means of the threaded connection 24. The other telescoping member 20 is fixed to the vehicle body 5 by means of the flange 25 so as to enable telescoping therein of the member 18 upon impacts against the bumper 6a'.
FIG. 10 further illustrates the use of a soft-elastic bumper strip 26 fixed to the front of the bumper 6a', such as by means of the T-shaped flange 27 at the front of the bumper profile.
In addition, the upper strip 2'" of the bumper covering 1'" is fixed to the vehicle body 5 so as to override the upper edge 10 of the bumper profile.
FIG. 11 illustrates in partial cross-section the construction of the bumper covering 1 having a subdivision or interruption. In FIG. 11, the subdivision is arranged in the region of the transition from the upper strip 2 to the pocket-shaped lateral part 9, but may also be realized at the center of the covering strip. The interruption occurs along the line of intersection 28 wherein the parts abut one another by means of an override or telescoping of one part with respect to the other.
While we have shown and described several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as known to a person skilled in the art, and we therefore do not wish to be limited to the details shown and described herein but intend to cover all such changes and modifications as are obvious to one of ordinary skill in the art.
