Abstract
This disclosure concerns crush resistant bumpers suitable for use on vehicles. There is disclosed a resilient bumper cushion rigidly mounted on the vehicle and having an outwardly facing impact surface. A flexible belt is connected to the cushion in the vicinity of the impact surface and extends along the entire length of the cushion. The belt is connected to the cushion at points lying along the entire length of the interface between the belt and the cushion in order to disperse localized impact forces throughout the cushion.
Claims9
A crush resistant bumper for protecting an object against impact collisions, said object having a continuous elongate support surface for said bumper;
- said bumper comprising:
- an elongate resilient cushion member having one side disposed on said support surface of said object, said one side being attached to said support surface in a substantially continuous line along substantially the entire length of said cushion member, said cushion member having an impact accepting surface on the side thereof which is opposite said one side and faces away from said support surface;
- and
- a flexible, pliant band of high tensile strength which is substantially stable in its longitudinal dimension, said band being secured on said cushion member in a region thereof which is closer to said impact accepting surface than to said support surface, said band further being attached to said cushion member at points which define a substantially continuous line substantially coextensive with the long dimension of said impact accepting surface,
- whereby forces impacting against a restricted area of said bumper are distributed longitudinally by said band to and along said cushion member to resist permanent crushing of said cushion member in the vicinity of the impact area.
