Abstract: A vehicle safety parapet comprises a plurality of rails (18, 24, 28) supported at varying heights on uprights (12). A first of the rails comprises a steel box-section supported at each upright by bracketing means (20) configured to collapse when a horizontal impact load is applied to the rail, such that the first rail is displaced towards the upright. At least one other rail extends from the uprights by a greater distance than the first rail when the bracketing means has collapsed.

Abstract: An improved handgrip adapter system for a bicycle which provides closely spaced handgrips positioned below and in front the a normal bicycle handlebar crosspiece. The handgrips comprise a pair of tubular members having clamps at one end adapted to be clamped to the crosspiece of normal bicycle handlebars. The tubes extend forward and downward from the crosspiece, curving down and back to provide a comfortable gripping surface for a rider. The handgrips may be positioned a suitable distance apart, selected in accordance with the size and preference of the rider, with the handgrips preferably positioned so that the hands low and are relatively close together, so that the rider's hands and arms are within the horizontal chest dimension. The handgrips extend further to the front than the handlebar handgrips, so that the rider's back is substantially horizontal. The handgrips extend slightly toward each other to acccommodate the rider's arms angling in from the shoulders for maximum riding comfort.
