ABSTRACT:
This energy absorbing bumper mount comprises a spring bracket assembly which includes a pair of diverging spring arms that carry pins on the outer end thereof. A preloaded yieldable energy absorbing band of oriented plastic material is stretched across the arms by attachment to the pins. On impact of a bumper attached to the spring arms, the pins are laterally displaced from one another as the spring arms are deflected. Energy is absorbed by the stretching of the band and by deflection of the spring arms. Rebound is controlled with the slow recovery rate of the band acting as a buckling column to retard recovery of the spring arms to their normal undeflected position.
