Abstract: The inventor, Ian Popoff, of Encinitas, Calif., wishes to disclose the novel utility of the Passenger Safety Handlebar. The Passenger Safety Handlebar is a fixed-mounted device to be used with in-line-seating arrangement vehicles, such as motorcycles, snowmobiles, personal watercraft, all-terrain vehicles, and the like, to improve passenger safety and stability while using such vehicles. What is novel with respect to the Passenger Safety Handlebar is primarily the secured-mounting properties of the device to the vehicle (as opposed to the driver of such vehicle), which are not observed in the prior art. Second, the innate nature of the Passenger Safety Handlebar predisposes it against action or movement of either the passenger or driver to each other. Further, the actual location of the Passenger Safety Handlebar is novel with respect to prior art, in that it is forward of the driver of the vehicle, rather than lateral or behind.
