摘要： Several embodiments of wheeled vehicles, such as wheelchairs, that are adapted to traverse obstacles are disclosed. The wheeled vehicles include a frame, drive wheels, front anti-tip wheels positioned in front of the drive wheels, and rear anti-tip wheels positioned behind the drive wheels. One exemplary vehicle includes front anti-tip wheels supported by rigid arms that are fixed to the frame and drive assemblies that are independently suspended from the frame. Another exemplary vehicle includes a linkage that links the front and rear anti-tip wheels, such that movement of one of the front anti-tip wheel or the rear anti-tip wheel relative to the frame causes movement of the other wheel relative to the frame.

摘要： A motor-driven chair has a central drive wheel located beneath the seat and linked so as to be aligned with the facing direction of the seat. A user turns the direction of motion by rotating the seat relative to a surrounding stabilizer assembly so as to turn the seat and the drive wheel towards a direction in which he wishes to move. A suspension arrangement maintains a desired distribution of user load between the drive wheel and the stabilizer assembly. A combination of fixed-axis wheels with castered wheels provides angular anchoring of the stabilizer assembly to facilitate the seat steering process. The entire structure is preferably foldable for easy transportation and storage.

摘要： A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

摘要： A wheelchair suspension assembly includes a frame, a drive assembly, an anti-tip linkage, a front anti-tip wheel, and a rear anti-tip wheel. The drive assembly includes a drive wheel. The front anti-tip wheel is positioned forward of the drive wheel by the anti-tip linkage. The rear anti-tip wheel is positioned rearward of the drive wheel the anti-tip linkage. The anti-tip linkage couples the front anti-tip wheel to the rear anti-tip wheel such that upward movement of the front anti-tip wheel relative to the frame causes upward movement of the rear anti-tip wheel relative to the frame. The anti-tip linkage includes a front anti-tip pivot arm that is pivotally coupled to the frame, a rear anti-tip pivot arm that is pivotally coupled to the frame, and a connecting link that couples the front anti-tip pivot arm and the rear anti-tip pivot arm.

摘要： A seated vehicle comprises a frame, one or more first wheels at a first position relative to the frame, one or more second wheels at a second position relative to the frame, and a wheel-positioning system. The wheel-positioning system includes one or more arms pivotally coupled to the frame, and an adjustment mechanism operatively coupled to a first position of the one or more arms. The one or more first wheels are operatively coupled to a second position of the one or more arms. The adjustment mechanism moves the one or more arms between a first position and a second position so that the one or more first wheels are in a first position relative to the one or more second wheels when the one or more arms are in the first position and are in a second position relative to the one or more second wheels when the one or more arms are in the second position.
