Abstract: A reversible seating mechanism includes a frame and a cross member pivotally supported on the frame for rotational movement in a plane generally parallel to the frame to define a tilt angle. A mounting plate is pivotally supported on the cross member for rotational movement in a plane generally parallel to the cross member to define one of a forward and rearward facing orientation. The mounting plate is moveable on the cross member to be oriented to the tilt angle. A tilt limiter restricts movement of the mounting plate between the forward and rearward facing orientations until the tilt angle is adjusted to a preset angle. The tilt limiter limits a forward facing tilt angle to an angle less than a rearward tilt angle.

Abstract: A backrest mounting system provides angular and height adjustment of a backrest shell independent of backrest canes. The backrest mounting system attaches to a centrally located mounting structure on the backrest shell and defines at least two pivot axes that determine the angular position of the backrest shell relative to a wheelchair seat.

Abstract: An adjustable backrest support provides a seat back angle adjustment that eases the task of adjusting the position of a wheelchair backrest while keeping the user seated in their wheelchair. In one embodiment, the adjustable backrest support includes a strut, an adjuster ring, an adjusting barrel nut, an angle adjuster, and a clamping system including a clamp. The clamp may include clamping screws that permit adjustment of the seat back reclining angle the angle or the seat back lateral position when loosened.

Abstract: An air insert is designed for a proper fit into a cushion pelvic loading area that has sloped walls for positioning and properly supporting the human pelvis. The air insert may be segmented, or pre-contoured by the manufacturer, so as to be designed for a proper fit into the PLA. The seat cushion and the insert will provide comfort and support to the users.

Abstract: A seat cushion system includes a seat cushion assembly and at least one supplemental pad attached to a portion of the seat cushion assembly. The seat cushion assembly and the at least one supplemental pad include chambers that may be filled with a fluid to provide isolation between a user and a wheelchair or other seating structure.

Abstract: An assembly for mounting a seat back shell to a wheelchair seat back cane comprises a first portion attachable to the seat back cane and a second portion attachable to the seat back shell. The portions mate to form a point of attachment by aligning one of the portions with the other portion and displacing one of the portions in relation to the other portion.
