The present disclosure includes a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A convertible transport system including a seat portion, a back support portion, and a pivoting mechanism coupled to the seat portion and to the back support portion. The pivoting mechanism is configured to adjust and lock the back support portion relative to the seat portion, the pivoting mechanism having three operative states: a free pivoting state allowing the back support portion to pivot relative to the seat portion about an axis; a ratcheting state allowing the back support portion to only pivot toward the seat portion about the axis; and a locking state in which the pivoting mechanism is locked to thereby prevent a pivoting movement of the back support portion relative to the seat portion.

The leg support for a motorized chair is an accessory that is adapted to be mounted onto a motorized chair in order to support a leg of an end user that is riding said motorized chair. The leg support includes a first armature that is adapted to be affixed to and extend upwardly from a motorized chair floor surface. The first armature may employ the use of at least one mounting bracket to rigidly affix the first armature to the motorized chair. The first armature extends upwardly and includes a bend that designates a second armature portion. A leg rest is selectively bolted to the second armature portion. The leg rest is supported at a horizontal orientation with respect to the motorized chair. The leg rest includes at least one leg rest bracket to secure the leg rest to the second armature portion.

A chair includes a control system for moving the chair between seated and standing configurations to thereby help facility an occupant's egress out of, or ingress into, the chair. One or more controls are provided on the chair that enable the occupant to control the timing of when the chair's movement between the configurations starts, what speed the chair moves at, and when the chair stops. A caregiver control panel provides the caregiver with multiple options for dictating what aspects of the chair's movement between the configurations the occupant is able to control. In some embodiments, a controller dynamically adjusts the speed of the chair based on shifts in the occupant's weight during the transition between the standing and seated configurations, as detected by one or more force sensors. The force sensors may be integrated into the armrests, the seat, the backrest, a combination of these, or elsewhere.

A chair includes a frame unit including a seat frame, a leg rest that is pivotally mounted to the seat frame, and a rest adjusting mechanism that is connected between the leg rest and the seat frame. The rest adjusting mechanism is convertible between an unlocked state, where the leg rest is permitted to pivot relative to the seat frame, and a locked state, where the leg rest is not permitted to pivot relative to the seat frame.

A lift chair includes a lift mechanism that maintains a continuous seating position during forward and elevated movement by supporting the occupant's seat, arms and back. The mobile section of the chair will also lower the occupant to the normal seating height. The gel cushion seating surface is attached at least to the moveable section of the lift chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support area at multiple points on the occupant's buttocks and thighs. This provides a comforting massage which reduces stress on the body associated with prolonged seating.

An assistive wheelchair that provides stand-up capability, vertical height adjustment while seated, and independent toileting is disclosed. The assistive wheelchair includes a verticalization system to move the user from a sitting to a more vertical position by tilting the while maintaining the proper center of gravity through the use of actuators and multi-bar linkages. The verticalization system also allows the seat to move up and down without modifying its tilt angle in order to change the height of the seat. An opening system provides for transversal movement of the wheels, to increase the width of the base of the wheelchair in order to create a space wide enough between the wheels to fit over a lavatory. A trap door seat is also provided that is lowered and moved from under the wheelchair to provide an opening in the wheelchair main seat during toileting.

The convertible wheelchair is similar to a conventional wheelchair, but includes a reclining back support and an additional leg support plate. As the back support is pivoted, with respect to the seat, into a reclining position, the leg support plate is driven to pivot upward. When the back support is pivoted into a fully reclining position, the seat, the back support and the leg support plate are positioned parallel and co-planar with respect to one another. Similar to a conventional wheelchair, the convertible wheelchair includes a frame, the seat, which is secured to an upper end of the frame, the back support, which is secured to a rear end of the frame and is pivotally coupled to the seat, a pair of rear wheels rotatably secured to the rear end of the frame, and a pair of front wheels rotatably secured to the front end of the frame.

Systems and methods of wheelchair systems herein provide a wheelchair capable of providing a brace system that moves between retracted and deployed positions to provide a physical support to the legs of the user to assist the user in transition between a plurality of user positions. Embodiments determine a user request for such assistance and then either deploys and/or retracts the brace system. Embodiments provide for assistance independent of additional people, such as aides, to assist the user in moving or transitioning between the plurality of user positions while also allowing or permitting the wheelchair to function normally when the brace system is in the retracted position.

A multifunction mobility device includes a frame that includes a seat member, a first wheeled leg ember coupled to a first side of the seat member and a second wheeled leg member coupled to a second side of the seat member. The first wheeled leg member and the second wheeled leg member each includes an upper leg portion pivotally coupled to the seat member at a distal end and defining an upper arm recess, and a lower leg portion pivotally coupled to the upper leg portion, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode where the upper leg portion is pivoted relative to the lower leg portion such that the lower leg portion nests into the upper arm recess.
