A mechanical type lifting shifter provided below a wheelchair body, including a bottom supporting assembly having a pair of oppositely arranged supporting members and gear rack columns provided on the supporting members; a movable upper supporting assembly having movable supporting members slidably sleeving the gear rack columns; a gear roller assembly having a rotating shaft and a pair of lifting gears provided on the two end portions of the rotating shaft; two ends of the rotating shaft are respectively and fixedly connected to a pair of movable supporting members and support the movable supporting members, and the lifting gears are engaged with the gear rack columns; a pedal transmission assembly mounted on the rotating shaft and in transmission connection with the rotating shaft; and a pedal clutch assembly connected to the pedal transmission assembly to switch clockwise and anti-clockwise motion transmission between the pedal transmission assembly and the rotating shaft.

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 wheel chair lifting device with a stationary platform, a movable lift assembly, four motorized scissors jacks, a foot stand platform, a battery power supply and a wireless lift controller and receiver. The four scissors jacks each placed on one corner of the stationary platform. The movable lift assembly is attached at each corner to the for scissors jacks. The movable assembly can of be lifted and lowered by the four scissors jacks. The scissors jacks are powered by the battery power supply. The motors of the lift jacks are activated by a wireless hand held controller. The base of the movable lift assembly is level with the stationary platform so that no ramp is required for rolling a wheel chair onto the lift assembly.

The wheelchair accessible seating locations provide new immersive experiences to people using wheelchairs in viewing an event at a venue while being ADA-compliant. These wheelchair accessible seating locations can be moved along one or more principal axes, such as the x-axis, the y-axis, and/or the z-axis of the Cartesian coordinate system to provide some examples, as the people using wheelchairs is viewing the event. These wheelchair accessible seating locations can oscillate along the one or more principal axes to generate vibrations to create the experience of touch to the people using wheelchairs to provide these new immersive experiences to the people using wheelchairs in viewing the event. These movements of the wheelchair accessible seating locations can coincide with, for example, be synchronized to, the event to provide the people using wheelchairs with a substantially similar immersive experience as other spectators of the event that are seated in the seats within the venue.

A device for supporting a wheelchair includes a frame and a support system. The first end of the frame is attached to an axle of the wheelchair. The second end of the frame is attached to a wheel for allowing translation of the device over a surface. The support system is coupled to the frame and may be positioned to catch a back of the wheelchair upon reclining of the wheelchair during a wheelie. The position of the support system with respect to the frame is adjustable in order to catch the wheelchair at varying angles of reclining. As the user of a wheelchair develops skill in performing a wheelie, the position of the support system may be moved further away from the wheelchair.

A wheelchair includes a lower assembly including a lower frame having wheels rotatably mounted thereto, an upper assembly including an upper frame supporting a seat, a backrest and at least one movable armrest, and a lift mechanism configured to move the upper assembly relative to the lower assembly between a lowered position and a raised position, wherein a user can move sideways out of the seat in the raised position with the movable armrest lowered.

A bariatric chair for use in easing the ingress and egress of bariatric patients from medical furniture includes a platform mounted within a cavity defined by the chair base. The platform includes a pair of pistons and a pair of legs each pivotably attached to a rectangular base that is stored in a retracted position within the base when not in use but drops down when engaged to lift the chair vertically. Due to the pistons extending beyond the legs, the pivotable nature of the attachment creates a rotation of approximately fifteen degrees (15°) in the chair base, assisting the bariatric patient when trying to exit the chair. A method of lifting the chair is also provided.

A user control device for a transporter. The user control device can communicate with the transporter via electrical interface(s) that can facilitate communication and data processing among the user interface device and controllers that can control the movement of the transporter. The user control device can perform automated actions based on the environment in which the transporter operates and the user's desired movement of the transporter. External applications can enable monitoring and control of the transporter.

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.

A patient support apparatus comprises a base and a support frame. The patient support apparatus also comprises a lift assembly that operates to lift and lower the support frame relative to the base. The lift assembly comprises lift members that extend and collapse to lift and lower the support frame. Guides operate to guide movement of the lift members during operation. In some cases guided bodies coupled to the lift members move passively in the guides. In other embodiments, driven members coupled to the lift members move actively in the guides to cause lifting and lowering of the support frame.
