摘要： An anti-tip system is provided for improving the stability of a powered vehicle, such as a powered wheelchair. The vehicle includes a drive-train assembly which is pivotally mounted to a main structural frame. A suspension system biases the drive-train assembly and its connected anti-tip wheel to a predetermined resting position. The drive-train assembly bi-directionally rotates about a pivot in response to torque applied to or acceleration forces on the vehicle. A linkage arrangement is provided and is characterized by a suspension arm pivotally mounting to the main structural frame about a pivot at one end thereof and an anti-tip wheel at the other end. The linkage may further include at least one link operable to transfer the bi-directional displacement of the drive-train assembly to the suspension arm. The link may include a bell crank member and/or may be resiliently compressible.

摘要： A wheelchair according to one embodiment includes a frame, a pair of drive wheels operatively coupled to the frame, a drive operatively coupled to each drive wheel, and a pair of anti-tip assemblies. Each anti-tip assembly includes a first member, a second member pivotally coupled to the first member at a joint that defines a pivot axis, an anti-tip wheel rotatably coupled to the second member, and a locking mechanism. The second member is capable of pivoting about the pivot axis between an extended position and a collapsed position. The locking mechanism is configured to selectively lock the second member in the extended position.

摘要： A powered wheelchair includes a frame, a chair, a pair of drive wheels, a pair of rear wheels, and a pair of front wheels. Each front wheel is part of a front arm assembly that is rigidly coupled to a drive via a mounting plate. The mounting plate is connected to the wheelchair frame by a pivot. The drives are transversely mounted. The batteries are disposed rearward of the drives. The rear wheels are part of an articulating beam assembly and are positioned to provide access to the batteries from the rear of the wheelchair with ease.

摘要： A transportable power wheelchair is provided which employs a variety of detachable modules to facilitate transportation and storage. The wheelchair may be readily disassembled/reassembled by a single individual without assistance and/or the need for special tools. The wheelchair includes a power supply unit, a pair of primary drive wheels, and a drive train subassembly mounting and independently driving each at least one of the drive wheels. First and second main frame subassemblies preferably have mounted thereon one of the drive train subassemblies. The power supply unit is also detachably mounted therebetween. At least one cross member assembly connects the main frame subassemblies. The cross member assembly, in combination with the main frame subassemblies, define the main frame assembly. A seat is also detachably mounted to the main frame assembly by means of the cross members.
