Abstract: Breathing mask assemblies that include adjustable forehead supports are disclosed herein. In one embodiment, a forehead support is adjustably coupled to a central or main body of the breathing mask. A clamp is configured to lock the position of the forehead support relative to the central body and to lock forehead support at multiple different positions. In one exemplary embodiment, the forehead support may be locked at any position along a path of travel between a first position and a second position.

Abstract: A foldable wheelchair includes a cross brace assembly having first and second brace members pivotally secured to one another. First ends of the brace members are clamped to respective side frames of the wheelchair. Second ends of the brace members are removably secured to respective seat rails so that the cross brace assembly can be adjustably positioned forwardly and rearwardly along the side frames and seat rails. This provides for ease of seat depth adjustment that accommodates growth of the wheelchair user without having to purchase additional components.

Abstract: A wheelchair includes a frame having first and second longitudinal sides connected by a bridge and a seat module carried by the frame. A first power drive assembly is disposed on the frame first longitudinal side. The first power drive assembly includes a first swing arm pivotally secured to the frame, a first motor mounted to the first swing arm and a first wheel operably connected to the first motor. A second power drive assembly is disposed on the frame second longitudinal side. The second power drive assembly includes a second swing arm pivotally secured to the frame, a second motor mounted to the second swing arm and a second wheel operably connected to the second motor. A first resiliently biased anti-tip assembly is secured to both the frame first longitudinal side and the first motor. A second resiliently biased anti-tip assembly is secured to both the frame second longitudinal side and the second motor. A power supply is mounted on the frame for powering the first and second motors.

Abstract: The present invention is directed to a lightweight wheelchair having adjustable wheel camber, adjustable toe-in/toe-out positions, and front-to-rear adjustment of the wheel assembly relative to the frame. The wheel camber is changed by removable camber tubes having plugs in opposite ends with different angular relationships. The camber tube is removed from an axle tube, rotated through one hundred eighty degrees, and reinserted to change the wheel camber. The location of the angular recesses in the camber plugs addresses minor toe-in/toe-out adjustments while rotation of an axle tube provided with indicia assures that proper toe-in/toe-out adjustment is provided for larger wheel camber adjustments. The front to rear location of the wheels relative to the frame can be adjusted via a single fastener on each side. Moreover, the track width of the rear wheels can be adjusted in response to the change in wheel camber.

Abstract: A convertible wheelchair permits change over from an attended wheelchair arrangement to a self propelled wheelchair arrangement. The wheelchair accommodates both lateral and longitudinal dimensional changes. Further, the seat can pivot relative to the frame, as well as permitting a seat back to tilt relative to the seat portion. In the attended wheelchair arrangement, the rear wheels are simultaneously locked.

Abstract: A suspension system for a wheelchair comprises a frame, a pivot bar mounted to the frame through a hinge point, and a seat mounted on the pivot bar. The pivot bar is supported from the frame by a shock absorber and a helical spring so that impacts transferred to the frame through the wheelchair wheels are partially decoupled from the movement of the seat. The movement of the seat is constrained in a single plane along the longitudinal axis of the wheelchair.

Abstract: The sports wheelchair includes a frame portion (A) having left and right side frame portions. Rear wheel assemblies (B) are connected with the left and right side frame portions such that the rear wheels are connectable to the frame in any one of a plurality of positions and with an adjustable camber. A pair of front wheel assemblies (C) selectively interconnect front wheels with the frame with any one of a plurality of adjustable height, inward-outward, and forward-aft positions. An operator supporting seat (D) having a segmented center portion and an outer portion is selectively interconnected with the left and right side frame portions. A folding mechanism (E) enables the left and right side frame portions to be folded together for easier transportation and storage.

Abstract: A bed (A) has side rails (20, 22) and defines a patient supporting surface (38). A mounting assembly (B) includes a transverse member (50) which is clamped to the bed side rails and an upstanding post (58). A power module mounting bar (70) is slidably positioned on the upstanding post to be mounted thereto in a selectively adjustable vertical position and to be selectively swung about the axis of the post to a storage position. A power module (C) drives a shaft (98) through reciprocating angular displacement at a selectively adjustable speed and between selectively adjustable angular displacement limits. A patient joint flexing assembly (D) is connected with the power module shaft to flex a selected one of the patient's joints under motive force supplied by the power module. Commonly, a plurality of joint flexing assemblies are provided, each particularly adapted for flexing one of the patient's joints, such as a knee flexing assembly, an elbow flexing assembly, and the like.
