Abstract: A flexible step assembly for a vehicle configured to provide stability when being mounted by a user. The flexible step assembly includes a top-plate secured on the top of each side member through a backing plate. The top-plate each seat in a recess of an upper member that is connected to the vehicle and the top-plate and the upper member are connected by a resilient connection such that they can separate by an impact load but will be recoupled by the resilient connection. The top-plate is substantially bisected by its connection to the backing plate so that the backing plates are each substantially centered on the top plates.
