A medical chair includes a base, a seat section, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a scissor mechanism coupled to the leg rest to extend and contract the leg rest and an actuator mounted on one end relative to the seat section and having an extendible driving end coupled to the leg rest wherein when the extendible driving end extends the extendible driving end pivots the leg rest about the pivot axis and extends the scissor mechanism.

The invention relates to the field of wheelchairs and has been designed for the measurement of parameters for the adjustment of a seated position of the user. It relates to a device for the simulation of a seated position in a wheelchair, which includes a seat backrest (1) adjustable horizontally, vertically and during its reclination, two side seat pans (27) with armrests (3) with adjustable distance, a foldable seat pan (2) with adjustable reclination, two wheels (4) with adjustable horizontal and vertical position, and a footrest (5) with adjustable vertical position and its reclination, at least one electric motor or an electric piston (15) for the adjustment of the position of the adjustable components, an electronic circuit with special software for the control of the motors and the display of the measurements, as well as a virtual reality software. With this device, it is possible to measure the adjustment parameters for the seated position of a wheelchair user automatically and digitally by means of a software which is installed in the simulation device.

Disclosed is a wheelchair, and particularly to a wheelchair with a lifting function, which has a simple structure for automatically moving a seating block where a wheelchair user is sitting, and enables the seating block to have a lifting movement and a rotational movement, thereby simplifying a structure and assisting the wheelchair user in standing up safely

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

A wheelchair including a steering assembly configured to selectively attach to the wheelchair, the steering assembly including a steering member, a front wheel operably connected to the steering member, a frame assembly configured to carry the steering member and the front wheel, and a mounting assembly coupled to the frame assembly, and a drive assembly coupled to the wheelchair. The drive assembly is configured to operate in a first configuration in response to the steering assembly being detached from the wheelchair, and the drive assembly is configured to operate in a second configuration in response to the steering assembly being attached to the wheelchair.

A steering system for a wheelchair includes a steering device configured to be engaged by a user, a front wheel operably connected to the steering device, and a frame assembly configured to carry the steering device and the front wheel. The frame assembly is configured to removably engage a mounting member of the wheelchair. A mounting assembly can be coupled to the frame assembly. The mounting assembly is configured to selectively couple to the mounting member of the wheelchair and selectively electrically connect to a motorized drive assembly coupled to the wheelchair.

A wheel chair with several new and useful features is provided. Those new and useful features provide the wheel chair with enhanced lateral stability, automatic cocking of an automatic locking device whenever an occupant sits in the wheel chair, and a holding mechanism that enables the wheel chair to be freely wheeled about when there is no occupant, and automatically move to a cocked state as soon as an occupant sits on the chair. The result is an automatic locking system for a manual wheelchair that unlocks the wheels for intentional motion when the chair is occupied, and locks the wheelchair wheels immediately when it is unoccupied, yet in no way interferes with the typical locking mechanism of the standard manual wheelchair when so desired.

A rollator having a first side frame and a second side frame; the first side frame comprising a first side frame intervening structural portion; the second rolling side frame comprising a second side frame intervening structural portion; a central platform having a first platform side and a second platform side; and first and second track mechanisms respectively coupling the first and second side portions to the first and second platform sides of the central platform; the first and second track mechanisms permitting independent movement of said first and second side frames relative to said central platform.

A brake device including a brake unit; a contact device engageable by the brake unit and movable relative to the brake unit, wherein the brake unit includes at least one activation device and at least one brake member that includes a transmission member and a brake shoe that is pivotably supported in a pivot bearing at an end of the at least one brake member, wherein the at least one activation device engages the transmission member to move the at least one brake member towards the contact device until the brake shoe contacts the contact device in an activation position of the at least one brake member and the brake shoe, wherein the pivot bearing is arranged at the at least one brake member so that the pivot bearing is movable towards the contact device together with the transmission member.

An apparatus and system for facilitating the controlled ascent and descent of stepped or irregular inclines, such as a set or flight of stairs. In an embodiment, the invention comprises an apparatus and system that allows an operator to safely transport a heavy load up or down a flight of stairs. The invention may be utilized with, attached to or incorporated within a transporting carrier, such as a hand truck or hand cart, for transporting heavy cargo up or down stepped or irregular inclines. In an embodiment, the invention allows a wheel to rotate freely in one direction while regulating the rotation of said wheel in the opposite direction such that a braking force in said opposite direction is proportional to the apparent weight and angle of inclination of said carrier. In operation, a gravitationally induced increase in an apparent weight activates the invention's braking system, thereby providing a braking force to the carrier wheel.
