Abstract

Abstract A shock-absorbing bumper means (cushioning device for protecting cars, boats or other vehicles), comprising resilient tubular members of optional variation in cross-sectional shape, having tube-flattened portions, and containing gaseous material that may consist of: air, helium or other gas, preferably under pressure well above that of the atmosphere; cellular foam plastic; or, mixed with gas: a mass of mingled fibers, globules, or other small-diameter elements of small cross-sectional area (e.g., small, flexible, axially curved or straight tubes or rods of resilient rubber or other flexible or crushable material). The cushioning means may comprise separate bumpers at the front and rear of a vehicle, optionally also at the sides or it may extend all around a vehicle with or without integral, tube-flattened junctions between the tubular links. Each bumper element may comprise: only one flat-ended tube; a plurality of separate flatended tubes that are not strongly connected or a plurality of band-connected flat-ended tubes (tubular elements or links). The tubular elements are flexible, and because of their wider flattened ends may be long-repeatedly bent without damaging wrinkling, fracture of their material or change in length. Although this material may comprise gas-permeable resilient plastic (preferably enveloped in mesh or other fabric), it preferably is of ductile or resilient metal or of resilient, substantially impermeable, dense plastic. When of metal it may comprise thin copper, lead, aluminum, mild steel, or resilient steel, optionally sheathed in fabric.
