US Patent 9365256 Infant scooter

A vehicle for infants includes a footboard, a chassis with front and rear chassis supports, two front wheels, at least one rear wheel, a bar extending vertically from the front chassis support, a handle extending from the bar to be gripped by the vehicle's user, and optionally a removable seat. The vehicle is steered by the user's particular application of weight applied to the footboard in which the application of more weight to one side of the footboard (or the shifting of weight) causes the front wheels of the vehicle to steer the vehicle in the direction of that side.
