An impact resisting post (10), comprising a first resilient portion (14) and a second resilient portion (18) spaced transversely from said first resilient portion. A connection portion (16) interconnects said first and second portions. An intermediate portion (20) extends from said second resilient portion into said space between said first and second resilient portions wherein said resilient and intermediate portions are configured to resiliently respond to an impact, such that when said impact exerts a force on said second resilient portion towards said first resilient portion, said second portion moves resiliently towards said first portion under the influence of said force, until said intermediate portion contacts said first resilient portion thereby to restrict further resilient movement of said second portion relative to said first resilient portion. The intermediate portion has shape and dimension configured to inhibit permanent deformation of said second resilient portion and/or connection portion after said contact occurs. |
