Abstract: A bumper system for a go-kart has a plurality of bumper sections. The bumper section has a sufficient rigidity that displacement to one bumper section transmits motion to other bumper sections. A plurality of shock absorbers are provided, for example, rubber elements connected between the bumper sections and the frame. Consequently, impact at any one point is transmitted throughout the bumper system so that all the shock absorbers assist in absorbing the impact, rather than just the shock absorbers immediately adjacent the impact point. For the rear bumper system transverse motions guides are provided to support a rear bumper section, and to maintain the various bumper sections about a horizontal plane relative to the frame, while permitting the necessary horizontal motions, both longitudinally and laterally. The bumper sections may be connected together at their ends by pivots. Alternatively, the bumper sections may be continuous.

Abstract: An energy absorbing member (12) is installed in a bumper reinforcement (4) so that one end of the energy absorbing member (12) faces the side member (3) of an automobile. During an accident, if a force is applied to the bumper apparatus (2), the energy absorbing member (12) collapses like a bellows in order to absorb this shock. The energy absorbing member (12) will reliably collapse in this desired manner under many conditions, for example, where the automobile is large and heavy or where the accident occurs under a high-speed condition. The energy absorbing member (12) is of a tubular shape with smooth and straight surfaces so that the energy absorbing member (12) can be easily produced by an extraction forming method or the like. Furthermore, the energy absorbing member (12) is installed within the bumper reinforcement (14) so that the bumper apparatus (2) projects less from an automobile body (1) in comparison to conventional bumpers.

When the bumper moves towards the vehicle upon impact, the mating camming surfaces interact causing the molding to be deflected outwardly and the end portion of the bumper to slide therebeneath thus avoiding damage to the parts. Upon retraction of the bumper to its normal position, the spring mounting causes the molding to return to its normal position lying against the body of the vehicle.

Abstract: An energy absorbing bumper mounting arrangement including a longitudinally extending tubular member having a forward portion secured to a vehicle bumper and an aft portion slidably received in a circular opening formed in a vehicle frame portion. A cylindrical capsule of thermoplastic polyester elastomer material has a central passage telescopically receiving the tubular member aft portion.
