A lateral transfer system and method for transferring a patient between a fixed structure and a mobile vehicle. The system including A) a patient transfer device having a frame fixed to wheels and a carriage platform movably attached to the frame, the carriage platform having one or more extendable platform sections for lateral movement of the platform relative to the frame and wheels, and B) a stabilizer system for the patient transfer device. The stabilizer system including a portable platform having two opposing sloped ramps on a first and second sides thereof, a bracket fixedly attached to the platform adjacent a first end thereof, wherein the bracket is adapted for receiving a slide plate appendage attached to the frame of the patient transfer device, wherein the second end of the ramp has a length sufficient to prevent tipping of the platform during a patient transfer maneuver.

A waterproof chair for use when bathing is provided. The chair may include an on-board system for raising and lowering the chair between sitting and raised positions. The chair may be used by elderly persons to assist them in sitting and standing in a shower, for example. The chair may include a rechargeable battery for powering a linear actuator for moving the chair between sitting and raised positions. The chair may also be adapted to allow a seat on the chair to swivel relative to a base of the chair. The chair may include an automatic lock to restrict relative movement of the seat and the base when the seat is being raised, and then automatically unlock to again allow for swivel motion when the seat has been moved back into its sitting position. Hydraulic and pneumatic embodiments are also disclosed.

An adjustable wheelchair for ready assembly in accordance with embodiments of the invention are disclosed. In one embodiment, the wheelchair includes, an undercarriage including, a horizontal axle including a first end segment telescopically coupled to a body segment and a second end segment telescopically coupled to the body segment opposite the first end segment allowing for adjustment of the wheelchair width, and a tongue including a body segment telescopically coupled to an end segment allowing for adjustment of the wheelchair length, and a seat post including an end segment telescopically coupled to a body segment allowing for adjusting the wheelchair seat height; and a pair of wheels; and a swivel wheel coupled to the tongue of the undercarriage to support the wheelchair and provide mobility; and a seat bottom coupled to the end segment of the seat post for load-bearing support; and a seatback rotatably coupled to the seat bottom.

A dampening system is efficient in dampening vibration through a wheelchair frame. The system allows a lower base frame and wheels to be rigidly attached, while an upper seat frame is joined to the base frame through elastomeric dampening bushings to isolate the seat frame from the base frame. The bushings may be hidden in vertical upright tubes of the base frame. The bushings can also be used for supporting front caster forks and/or a rear axle assembly in isolation to the base frame.

A wheelchair frame comprises a base frame having a geometry that is structured and configured to be adjustable about a fixed pivot, wherein the base frame comprises a central frame and frame component that are adjustable via an angular adjustment.

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 seating furniture chassis having a height-adjustable seat surface, a drive means, a shaft, a height-adjustment mechanism and a threaded rod, wherein the drive means is coupled to the shaft and is designed to transmit a torque to the threaded rod by means of the shaft, and wherein the height-adjustment mechanism is coupled to the threaded rod and to the seat surface such that a rotation of the threaded rod is converted into a height adjustment of the seat surface by means of the height-adjustment mechanism, characterized in that a longitudinal axis of the shaft is not arranged parallel to a longitudinal axis of the threaded rod.

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.

An adjustable chair includes upper and lower base members, a seat assembly secured to the upper base member, and a chair adjusting mechanism. In an embodiment the upper base member is connected to the lower base member by first and second linking members each having a first end connected to the lower base member and a second end slideably received in corresponding first and second arcuate tracks disposed in the upper base member, such that movement of the second ends into and out of the tracks results in vertical movement of the seat assembly relative to the base. In a further embodiment the seat bottom and seat base comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat bottom to tilt relative to the seat base. In a further embodiment the seat bottom and seat back comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat back to recline relative to the seat bottom.
