Abstract: A foldable personal mobility vehicle is disclosed comprising first and second units having first and second wheels being rotatable about first and second axles. A drive unit rotates the second wheel for moving the foldable personal mobility vehicle. A pivot disposed substantially parallel to the first and second axles pivotably connects the first unit to the second unit for folding the personal mobility vehicle. The foldable personal mobility vehicle may include a folding unit for automatically folding the foldable personal mobility vehicle.

Abstract: A vehicle is disclosed having a reduced turning radius comprising a directional wheel assembly for turning the vehicle and a drive wheel assembly for driving the vehicle. The drive wheel assembly has a first and a second drive wheel independently driven by a first and a second motor through a control circuit. A counter-rotation circuit counter-rotates the first and second drive wheels upon a major turning position of the directional wheel assembly to enhance the turning of the vehicle. A reducing circuit reduces the speed of the motors upon a minor turning position of the directional wheel assembly. The vehicle may include a slide mechanism for providing a reduced wheelbase to further reduce the turning radius of the vehicle. One embodiment of the invention includes an improved steering device for controlling the directional wheel assembly.

Abstract: A retractable armrest is disclosed for a foldable chair. The chair has a seat and a backrest with the backrest being pivotably mounted to the seat by a chair pivot for movement between an operating position and a folded position. A link pivotably operates between armrest and the seat for enabling the armrest to be rotated into the retracted position when the backrest is in the operating position. The link rotates the armrest from the extended position to the retracted position upon the backrest being moved from the operating position to the folded position. The foldable chair is suitable for use on a personal mobility vehicle such as a scooter, a power wheel chair, a foldable personal mobility vehicle or any other suitable chair.

Abstract: A variable wheelbase personal mobility vehicle is disclosed comprising a front wheel assembly and a rear wheel assembly. A front wheel is pivotably mounted relative to the front wheel assembly for controlling the direction of movement of the personal mobility vehicle. Plural drive wheels are mounted relative to the rear wheel assembly for driving the personal mobility vehicle. A seat is connected to the rear wheel assembly for supporting an operator. A variable wheelbase mechanism varies the distance between the front wheel and the plural drive wheels.
