## Abstract

A vehicle for infants includes a footboard, a front and rear chassis support fixed to it, wherein each chassis support supports at least one wheel, a steering bar which is connected to the front chassis support, and gripping at the upper portion of the steering bar. The vehicle furthermore includes a seat which is preferably fixed to the steering bar. The invention furthermore relates to a vehicle for infants with two front wheels and at least one, preferably two, rear wheels, wherein the vehicle includes a seat which is preferably fixed to a steering bar of the vehicle, and wherein the vehicle includes gripping at the steering bar which, however, does not function as handle bar, and wherein at least the front chassis support of the vehicle includes a steering mechanism which permits to steer the vehicle by ways of shifting of weight.

## Claims

### Claim 1

Vehicle for infants comprising:
a footboard having a front chassis support with two front wheels mounted thereon and a rear chassis support with at least one rear wheel mounted thereon,
a steering bar upstanding from the front chassis support and having an axis extending along the length thereof, the steering bar being fixed to the front chassis so that the steering bar cannot turn about its axis relative to the front chassis,
a seat fixed to the steering bar,
a grip disposed on the steering bar, and
the two front wheels comprise a double-pivot steering wherein when the footboard is unloaded a spring resiliently biases the two front wheels into vertical alignment and when a load disposed on the footboard is shifted to one side, the front wheels are inclined toward each other so that the distance between the front wheels tapers at top of the front wheels which permits steering of the vehicle by means of shifting of weight on the footboard.

### Claim 2 (depends on 1)

Vehicle according to claim 1, wherein the at least one rear wheel comprises two rear wheels mounted on the rear chassis support, the two rear wheels comprising a double-pivot steering wherein when the footboard is unloaded a spring resiliently biases the two rear wheels into vertical alignment and when a load disposed on the footboard is shifted to one side, the rear wheels are inclined toward each other so that the distance between the rear wheels tapers at top of the rear wheels to thus permit a narrow curve radius.
