Abstract
A kart includes a frame, front and rear wheels rotatable about front and rear axle axes, and an impact protection structure surrounding the frame. The impact protection structure includes: at least one front protective element, at least one rear protective element, and at least one lateral protective element on each lateral side of the kart. Each of the at least one lateral protective element is mounted to a pivot bearing fixed to the frame so as to be pivotally adjustable about a frame vertical axis, and is disposed closer to the rear axle axis than to the front axle axis. Each of the pivot bearings includes a bearing block and a bearing pedestal pivotable relative to the bearing block. Each of the at least one lateral protective element engages the bearing pedestal of a corresponding pivot bearing. Shock-absorbing dampers are disposed between the frame and the protective elements.
