Abstract
A wheelchair includes a pivotable mechanism. The pivotable mechanism allows for a pivoting movement about an axis defined by an interface between adjacent components. These components may be (a) a seat member and a back member, (b) a seat member and a footrest, (c) a foot rest and a footplate support, (d) a baseplate and a footplate, or (e) a back member and a headrest.
Claims17
A dynamic foot plate for a wheelchair, the dynamic foot plate comprising:
- a base plate adapted to be secured to a wheelchair;
- at least one flexible element secured at a first end to the base plate;
- a foot plate secured to a second end of the at least one flexible element, such that in a neutral position, the foot plate is substantially parallel to the base plate and such that when a force is applied to the foot plate, the flexible element deflects so as to allow the foot plate to be oriented at an angle to the base plate.
A telescoping footrest for a wheelchair, the telescoping footrest comprising:
- a tube defining an interior;
- an elongate element slidably received within the interior of the tube;
- and
- a deformable element for controlling sliding movement of the elongate element within the interior of the tube.
A pivotable mechanism for a wheelchair, the pivotable mechanism comprising:
- an axle comprising at least one axle projection projecting from an outer surface of the axle;
- an annular hub comprising at least one hub projection projecting from an inner surface of the hub, wherein the axle is located within the hub;
- a biasing element located between the axle projection and the hub projection, such that rotation of at least one of the hub and the axle causes at least one of a compression and an extension of the biasing element.
A wheelchair comprising:
- a first dynamic component comprising a first pivotable mechanism for allowing a pivoting movement about a first axis defined by an interface between a seat member and a back member, wherein the first dynamic component comprises a biasing element for biasing the first dynamic component into a rest position;
- and
- a second dynamic component comprising a second pivotable mechanism for allowing a pivoting movement about a second axis defined by an interface between at least one of (a) a seat member and a back member, (b) a seat member and a footrest, (c) a foot rest and a footplate support, (d) a baseplate and a footplate, and (e) a back member and a headrest, wherein the second dynamic component comprises a biasing element for biasing the second dynamic component into a rest position.
