A CHASSIS

摘要

It is known to provide self-propelled vehicles for the disabled and infirm. Such vehicles generally have rigid, fabricated chassis to which are rotatably secured three or four support wheels. At least one of the support wheels is driven, typically by an electric motor. A disadvantage of such known vehicles is that they virtually have to be custom-built to suit differently sized purchasers thereof. The disclosure relates to a chassis (10) for a vehicle. The chassis (10) comprises a forward portion (11) and a rear portion (12), the two portions being releasably securable one to the other. The forward portion (11) includes a front sub-chassis (19) and an intermediate sub-chassis (20) rigidly securable one to another. The axial spacing of the front and intermediate sub-chassis (19, 20) is adjustable, thereby permitting the ready manufacture of various vehicles of different sizes from a common chassis design. A support (40) for a passenger seat is secured to the intermediate sub-chassis (20), and a handlebar (18) whereby the chassis (10) may be steered is secured to the front sub-chassis (19). Thus, adjustment of the length of the forward portion (11) automatically adjusts the position between the seat support (40) and the handlebar (18).
