SYNTHET C ABSORBER FOR B~MPERS
.~ The invention relates to ~ynthetlc absoxbers for bumpers for the destruction-free absorption of shock energy during the crashing of an automobile~ consisting of one bearing in the region of the bumper and one bearing in the region of the automobile body, hetween which an ele~ent is arranged in ~usp nsion.
In order to avold ~amage to the body o~ an automo~ile durin~ crashes in the region of low speeds, it is desirable to install an element between bu~pe:r and body, which trans~orms the resulting energy into heat, as far as possible.
Metallic hydraulic shock absorbers are known as elements, in which the oil is pressed across nozzles of a pi~ton into the free cylinder space. Because of the ~: 15 system-conditioned piston control ~n one direction, ~uch shock absorbers are unfavorable for slanting or one~ided 6hocks, such as occur frequently in driving acaidants. Also, the technical requirements and the maintenance required are great, as precision parts are involved.
Further, ~hock absorbers of synthetic material are known which oontain a honeycomb structure at the core, which de~orm permanently under loading and thereby absorb the shock energy.
BecauG~ of *he permanent deformation sf the construction, the aggregate muæt then be completely exchanged.
The ob~ect of the invention is to ~ind a synthetic absorber ~or a bumper, which, at a colliding speed of Le A 24 630 s~
2318~-66~8 the automobile of up to 8 kilometers per hour and a deformation path of less than 50 to ~0 millime~ers, and in whi~h, despite great energy ~ransformation and high absorption, no permanent material or shape changes appear after the removal of loading.
The object is solved according to the invention which provldes a shock absorber for bumpers providing damage-free absorption of shock energy during vehicle crashes for place~ent between a vehicle bumper and a vehicle body, the shock absorber consist.tng of at least one elastically defor~able element and a support body, the elastically deformable element and the support body each having mutually engaging flat sliding surfaces which ~orm an angle with respect to the direction of movement of the element, upon i~pact elastic body means between portions of the elastlcally deformable element and the support body adapted to influence the deformation and movement of the elastically deformable element during impact.
The construction according to the invention allows the solidity o~ the synthetic material under loading of the colliding forces to be used righ~ into the allowed limiting region, which, however, is never crossed, as the deformable elements then move off on the sliding surfaces. Further, it has been shown that due to the elastic body a force-distance gradient - the force rises steeply over a short distance and again rises slightly over a long distance, then falling steeply over a short distance - yields a hysteresis loop, from which it follows that a large amount of energy is transformed during the shock. As the movemen~ of the - :~ 2~35~3 23189-66~8 elemen~ is only slowly braked, the element, which, af~er all, is freely mobile, returns to its starting position without great vibra~ions.
It is thus po6sibl2 for the man skilled in the art to design the synthetic absorber suitable for use in a manner accordin~ to the demands by means of adequate constructive measures and choice of working materials.

3~35~(~3 It is possible, with an element with a central ~rame and ribs attached at both sides at an angle of 60 to 85, to determine in advance the ~tart of ~liding o~
the Eliding ~urfaces on the wall of the casing by means o~ elastic bodie6 and by ~eans of the moment of inertia or ths curvature of the ribs, 60 that the force di.stance gradlent can be made steep in the first section. Subsequently, ~ deformatlon occurs, which finally ends with a further rise o~ ~orce. After the removal o~ loading, the force i8 again braked over a short distanc As the elastic bodies do not impede this ~ovement, but even support it, the original shape is once ~ore attained. Through the hysteresis, a large part of the energy is transformed into heat, which can then flow of~ without obstruction.
In anothex 6ynthetic absorbex, the legs ~acing e~ch other, o~ 61anting or v-shaped element~ lying opposite each other in inv~rted formation, slide towards each other, wherein the sideways pressure besides ths pre-stres~ing yielded by shaping is ~urther increased by filling out both ~ides with synthetic foa~. At the same time~ the foam dampens the movements, by which ~eans increasing vibrations of the system are avoided.
In an advantageous embodiment, the ~liding ~urfaces are ~tructured by elevations tbumps) or depressions (grooves), all layered with frictional material, by which means the coefficient of sliding fric~ion can be varied according to the demands.
Synthetic foam foamed in situ has shown itself to be especially advantaseous for elastic bodies, as, besides the application of supporting force, it also prevents ov~r-oscillating during the removal of loading. The volume and the thickn~ss should be so great that the Le A 24 630 actual synthetic element i6 not yet damaged under complete compression~
Straight or bent elastic strlps ar conceivable, which bend under strong loadingO By changing the stif~ness, 5 for example by at least two fixing devices oP parallel strips anchored opposite each other, the time and size of the through-bending can be exactly se A ~urther adjustment is possible through the step-wise application and/or combination of various elastic bodies.
The supportinq force can also be suMmoned up by means of a brace, if the facing limbs of the ela~tic element are joined by tension devices such as ropes, ties an~/or ribs. After being put on an occasionally expanding body, the tension device is put under ever more tension during shrinking, by which means the contact ~orce of the li~bs against the co~mon ~liding surfaces is increased. The limbs, or the bearing, can therein be curved, so that the bearing of force can be influenc~d in desired ~a hion by ~eans of the : restriction of a contact sur~ace at various points in time.
~he beam tie remains ~nimpeded in its func~ioning right up to the c~mplete compression of the synthetic shock absorber by means of slits in the bearing.
Finally, a recoil device in the form of an elastic foam material or a 8pring can be installed, 60 that the shock absorber returns to itB starting position a~ter the shock event iB completed.
Further, it is advantageous to arrange the elements in Le A 24 630 a closed ~rame or a casing, wh~ ch can then ~e arranged as a unit ~shock absorber) between bumper and v~hi~le frame.
An exa~ple o~ the invention is represented in the figures and will be described i~ khe following. In the ~igures:
