<p>A load-cushioning device (5) comprises rolling rubber rings (10,11) for compressively engaging adjacent conical surfaces (6,7,8,9) of the device as the surfaces move together. The rings have a pair of longer toroidal segments (12,13) which are connected by a pair of shorter toroidal segments (14,15) which have cross-sections substantially smaller than those of the longer segments, such that the ring can be designed to resist to differing degrees lateral forces imparted to the device in different lateral directions.</p> |
