The present disclosure includes methods of operating 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. The methods adjust the maximum operational speed of the wheelchair when the seat is in an elevated position based on sensor data relating to one or more of the arm limiter position and the position of the frame.

The invention discloses an electric wheelchair DYYJBHD20, which belongs to the technical field of medical equipment, and includes a backrest tube. The backrest tube is provided on a seat assembly. Armrest components are provided on the left and right sides of the backrest tube. On the seat assembly, the front end of the seat assembly is connected to the front wheel through a front fork connection assembly, and the rear end of the seat assembly is connected to the rear wheel through a rear frame. A matching foot pedal is provided at the front fork connection assembly, and at the rear wheel Used with auxiliary wheels. As a new structural design, the electric wheelchair DYYJBHD20 has a small folding volume and light weight, and uses the latest material, carbon fiber, which is very convenient to optimize the appearance of the entire vehicle. At the same time, the density of the carbon fiber material is about of aluminium alloy, greatly reducing the weight of the entire vehicle.

In an electric vehicle, a seat on a mobile base can move between a sitting position in which a sitting surface faces the vehicle upper side, and a retracted position in which a seating portion having the sitting surface is retracted from the sitting position to the vehicle front side, a back plate on the mobile base can move between a raised position on the vehicle rear side and the vehicle upper side with respect to the seating portion in the sitting position, and a laid down position on the vehicle front side with respect to the raised position, a cargo bed portion on the mobile base is positioned on the vehicle lower side with respect to the seating portion of the seat in the sitting position and is positioned on the vehicle rear side with respect to the seating portion of the seat in the retracted position.

An electric vehicle includes: a mobile base capable of traveling by an electromotive drive; a seat including a seating portion having a sitting surface; and a battery capable of supplying electric power used in the electromotive drive. The seating portion of the seat includes a receiving portion capable of receiving the battery and arranged on a seat lower side with respect to the sitting surface. The mobile base is changeable between an expanded state in which a wheelbase is expanded and a contracted state in which the wheelbase is more contracted than in the expanded state. The seat is movable between a sitting position that the sitting surface faces a vehicle upper side in an expanded state of the mobile base, and a retracted position that the seating portion is retracted from the sitting position to a vehicle front side in a contracted state of the mobile base.

A mobility device that includes support assemblies that may be secured to feet, legs, thighs, and torso of a user. An exemplary mobility device may further include an actuator that may be coupled with the exemplary support assemblies and may actuate rotational movements of the exemplary support assemblies with respect to each other. Such movement of support assemblies may accordingly move respective limbs of a disabled user. An exemplary mobility device may allow for a user to change position from a lying position to a standing position or from a standing position to a sitting position, which may significantly increase mobility of a disabled user. An exemplary mobility device may further include an exemplary wheeled base that may allow a disabled user to further move around.

A robot according to an embodiment may include at least one driving motor for providing a driving force for driving of the robot, a position detector including at least one sensor or receiver for detecting a position of the robot, a pressure detector including at least one sensor for detecting whether a user who in on board the robot gets off the robot and a processor for detecting the position of the robot through the position detector, recognizing that the user has arrived at the destination when it is detected that the user gets off the robot and recognize that the user has not arrived at the destination when it is not detected that the user gets off the robot.

A lifting pad to be used with a wheelchair in order to provide additional comfort to a user is disclosed herein. The lifting pad comprises a cover with a seat portion and a backrest portion. The lifting pad also comprises a first slot formed in the seat portion and a second slot formed in the backrest portion in order to receive inserts such as foam inserts which are to provide comfort to a user. The lifting pad further comprises at least one foam insert arranged inside each of the first slot and the second slot found on the cover. The lifting pad is adapted to be placed on a seat to provide support and comfort to a user seated thereon.

The invention relates to means for releasably connecting a wheelchair backrest to a wheelchair frame. This is desirable to facilitate collapse of the wheelchair for transport or storage. In the preferred embodiment there is a wheelchair having a support frame, a backrest (16) and connector comprising a saddle (1) and a clamp (17). The saddle has a slot (3) with top and front openings and a locking lever (7). Two pins (12) are received in the slot so they extend through the front opening, and the lever (7) is able to move to divide the slot into top and bottom zones so that a lower one of the pins is prevented from being withdrawn from the slot via the top opening by the lever. The lever can then be moved to unblock the lower pin and allow the slot (3) and the pins (12) to be dissociated.

An improved positioning device (the DEVICE) comprises a new and unique concave angulated device for at least one of, but not limited to, stretching, supporting, bracing, rehabilitating, positioning, massaging, kneading, scratching, or exercising a body of a user. The DEVICE's new concave angulated and more user friendly surface addresses the need for a more anatomically responsive body positioning DEVICE for achieving improved results relative to, among other things, the above uses. This DEVICE includes multiple embodiments, which also may comprise various possible configurations, that enable the DEVICE to also function as a fulcrum or lever and/or be capable of uniquely dispersing a load during the interaction between the user and the DEVICE.

A wheelchair including a supporting frame and moving means configured to allow the movement of the wheelchair, the supporting frame having a seating area for a user of the wheelchair, the wheelchair including first actuation means configured to translate the seating area laterally and externally with respect to the supporting frame and, at least partially, with respect to the moving means, in a transfer configuration of the user, supporting means being operationally associated with the seating area, being able to be activated in the transfer configuration of the seating area to support the seating area with respect to the ground, the seating area being defined, in the transfer configuration, by a main seat and a secondary seat able to be activated in the transfer configuration of the seating area to increase the extension of the main seat.
