The impact absorbing buffer, primarily for use in multi-storey car parks, comprises a post portion 2 arranged in a first, generally upright position in normal use, the post being mounted to a supporting structure 4 and operatively connected to a replaceable resilient element 5 that permits movement from the first position to a second, displaced position and, under low impact conditions, a return movement to the first position upon release of the impact force. The movement of the post is preferably a pivotal movement. The resilient element may comprise a spring acting in compression or tension on the base of the post. Alternatively, a spring may extend up the inside of the post, and may then extend out of an opening in the post and back to the supporting structure. A resilient element, preferably a coil spring, may encircle the base of the post. Alternatively the resilient element may comprise a torsion bar. |
