A post assembly for absorbing impact from a vehicle including a post, a footing and a lever arm connecting the post to the footing at a hinge region, wherein:
- the footing, lever arm and hinge region are formed from a common base plate, with the footing and lever arm being separated by an elongate slot that extends in a direction away from an impact side of the plate and terminates at the hinge region, located toward a rear side of the plate;
- and
- the footing includes at least one aperture located toward the impact side of the plate, to receive a corresponding fastener to anchor the post assembly to a support surface;
- whereby
- under an impact load, the hinge region plastically deforms and the lever arm and post deflect about the footing, away from the impact side of the plate.
