Abstract:
A seating system comprises a mount for securing a backrest to a frame. The mount comprises two or more mating members. At least one of the mating members has a generally curved radial surface that is engageable with the other mating members to lock together the backrest with respect to frame.
Abstract:
A level on a wheelchair allows the cambered rear wheels to be easily adjusted to eliminate toe-in/toe-out. The level comprises a ball encased in a curved track. The curve track is formed in a clear housing that mounts to the underside of a wheelchair camber tube or wheel axle. The camber tube or wheel axle is rotated until the ball aligns with an indicator mark indicating that toe-in/out has been eliminated from the cambered wheels.
Abstract:
An angle adjustable camber assembly is adapted to support the wheel of a wheelchair having a seat, the rear of which is at a given rear seat height. The assembly comprises a movable member for supporting the wheel. The movable member is adapted to translate and rotate so as to be able to selectively position the wheel at any one of a variety of camber angles while substantially maintaining the rear seat height and a spacing between the top of the wheel and the seat frame.

Abstract:
The vehicle comprises a base and a seat moveable along a curve having a focal point. The vehicle is adjustable to position an occupant in the seat to achieve a desired position for the center of gravity of the occupant relative to the focal point of the curve. A method for minimizing effort required to tilt the seat oil a personal mobility vehicle comprises the steps of providing a personal mobility vehicle having a seat that is adapted to move along an arc having a center of curvature, positioning the seat substantially horizontally, providing an occupant in the seat, and adjusting the position of the vehicle occupant's center of gravity so that the center of gravity is substantially equal to or below the center of curvature of the arc.
Abstract:
A wheel mount assembly adapted for use in securing a camber tube to a wheelchair frame comprises an axle plate, at least one axially displaceable member adapted to be fixed in relation to the axle plate, and at least one radially displaceable member adjacent the axially displaceable members. The axially displaceable member is adapted to be axially displaced to cause the radially displaceable member to be displaced to tighten against the camber tube to hold the camber tube in place.
Abstract:
A seat cover, and a method for producing a seat cover, minimizes surface tension in the cover material, when the cover conforms to a highly contoured shape.

Abstract:
A power wheelchair incorporates inclinometers to measure angle of pitch and angle of roll. An inclinometer signal is used as an input to a controller. The controller alters drive parameters, such as maximum acceleration, deceleration, and minimum turning radius according to the pitch angle and roll angle of the terrain upon which the wheelchair is operated.
