摘要： A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction.

摘要： A personal mobility vehicle includes an base unit having a frame and front and rear pivot arms pivotally mounted at respective front and rear pivot points. The front and rear pivot arms support casters. A drive unit having a ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. The base unit may also include a drive unit that is pivotally supported on the base unit by a torque arm and a suspension system that includes a suspension stop. The torque arm selectively disengages the suspension stop to allow movement of the front caster wheel in response to the terrain traversed.

摘要： An improved wheel assembly comprises a caster fork, a caster wheel rotatably supported by the caster fork, and a caster swivel post defining an axis about which the caster fork rotates. The caster swivel post is being adapted to rotate about a pivot axis within a cylindrical housing. Alternatively, the wheel assembly has an adjustable axle for varying the camber angle of a wheel. The wheel assembly comprises a housing and an axle supported by the housing. The axle in turn rotatably supports a wheel. The axle is adapted to rotate about a pivot axis within a cylindrical housing.

摘要： An improved wheel assembly comprises a caster swivel post that is adapted to pivot about a pivot axis transverse to the caster swivel post. A caster fork is supported for rotation relative to the caster swivel post and rotatably supports a caster wheel. The caster swivel post is adapted selectively pivot about the pivot axis that is transverse to the caster swivel post or be held in a substantially fixed position. A setscrew can be threadable into an upper end of a pivot nut to hold the pivot nut and thus the caster swivel post in a fixed position within the housing.

摘要： A seat back assembly for connecting a seat back shell to the seat back tubes of a wheelchair comprises a shell, upper and lower shell connectors, and upper and lower side plate portions. The lower shell connector is mounted to a lower portion of the shell. The upper shell connector is mounted to an upper portion of the shell. The upper side plate portion is adapted to be mounted to an upper portion of the seat back tube. The lower side plate portion is adapted to be mounted to a lower portion of the seat back tube at a position substantially co-linear to the posterior superior illiac spine (PSIS) of a user. The lower shell connector and the lower side plate portion are pivotally engageable with one another along a pivot axis. The upper shell connector and the upper side plate portion are attachable relative to one another at discrete locations so as to permit the angular disposition of the shell to be adjusted.
