Abstract
Abstract Shock-absorbing bumper means for cars, boats or other vehicles, comprising resilient, tubular cushioning members of optional variation in cross-sectional shape, containing gaseous material that may be: pressurized air or other gas; gas-cell-containing foam plastic; or a gas-containing mass (optionally pressurized) of separate fibers, globules, or small-diameter elements (very small flexible tubes containing gaseous material or elongated rods of resilient rubber or other flexible or crushable material). The cushioning means may be only at the front and/or rear of the vehicle or may extend around it, with or without integral junctions between the tubular elements. The tubular members may have axes that are: horizontal; vertical or upright; optionally either upright or horizontal; or they may comprise outer horizontal tubular sheaths and inner vertical tubular elements. The tubular-member material may comprise: ductile or resilient metal - e.g., copper, lead, soft iron, resilient steel, with or without mesh or other reinforcing material; or flexible plastic (preferably fabric-reinforced rubber). The tubular members may comprise flat-ended tubular elements that are either separate tubes or tubular links in a bumper band around a portion or all of the vehicle, some of these links optionally comprising a fender above a wheel and a running-board-like side bumper-step. The tubular elements may comprise relatively wide, spring-like bands of resilient steel or the like, acting when flexed to compress fibers or other small filler elements.
