The invention relates to an adjusting device 2 for vehicles 1, in particular electric wheel chairs or rehabilitation vehicles, recumbent systems and nursing beds, comprising at least one mounting plate 3 and one support plate 4 with a lifting device 5 comprising at least two scissor mountings 20, which are arranged at the longitudinal side edge or in a corner region of the mounting 3 or support plate 4 each and are vertically adjustable by a driving means, wherein each scissor mounting 20 is formed as double scissors and includes a first, lower scissor element 21 and a second, upper scissor element 22 which are connected to each other at one end via a common rotation pin, and the lower scissor element 21 is connected at the other end to the mounting plate 3, and the upper scissor element 22 is connected at the other end to the support plate 4 via fastening means. In order to achieve a diagonal tilting of the adjusting device, according to the invention, the at least one fastening means consists of a bracket 35 connected to the support plate 4 and a fastening unit 30 axially movable with respect to the bracket 35 at which the ends of the upper scissor elements 22 of at least one scissor mounting 20 are hinged. By means of the bracket 35 and the fastening unit 30, an axial moveability in the longitudinal direction of the vehicle seat 13 is permitted so that no deadlock can occur even in extreme positions of the scissor mountings 20.

A removably mounted wheelchair lift device that can elevate the wheelchair and its user. The lift device has a novel lifting mechanism which has an upper plate, a lower plate, a knee plate, an upper interior link, an upper exterior link, a lower interior link, a lower exterior link and a transfer link. The various parts of the lifting mechanism are pivotally attached to one another in a manner which provides a linear and precise extension and retraction. Extension and retraction of the lifting mechanism is achieved by a rotary electric motor and gear drive which introduce a torque between adjacent parts of the lifting mechanism. The lifting mechanism maintains a parallel relationship between its top and bottom plates throughout its range of motion. The lift device may also be used in other applications where the level or angle of the equipment or surfaces being supported must remain constant regardless of height. Other applications may include, but are not limited to, supporting hospital beds, medical operation tables, manufacturing work stations, office work stations, pallet stand, and other warehouse and storage applications.

A mobility scooter control system includes a remote control console having a wireless transmitter and switches. A status detection circuit is integrated with the switches. The status detection circuit emits a pulse on a regular cycle. After the pulse passes the respective switch following a change in state of the switch, a wireless transmission is sent. A controller is electronically connected to a motor. The control system has a regular operation mode in which direction of movement and speed limit functions are responsive to instructions inputted to the controller, and, in the absence of user instruction, the controller does not instruct movement of the motor. The control system has a Sabbath operation mode in which the direction of movement and speed limit functions are responsive only to signals from the wireless transmitter, and, in the absence of user instruction, the controller instructs the motor to continuously cycle backward and forward.

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.

A propulsion assist device for a wheelchair having a hand rim slideably housed inside a channel of a frame pivotably connected to a lever arm. The frame is further comprised of a portion of grip material positioned inside the channel along an underside of a top of the frame. When a pair of devices are installed on a pair of hand rims of the wheelchair, the wheelchair is moved forward by a coordinated rowing motion of both lever arms forwards and then backwards along the hand rim. The pivoting motion of the frame causes the grip material sandwiched between the frame and the hand rim to pressure grip the hand rim and turn it when a user moves the lever arms through their rowing motion. Repositioning the frame along the hand rim causes the gripping material to release and slide along the hand rim before repositioning.

A hybrid seating cushion made up of a cushion base and a cushion insert. The cushion base has a seating surface in which a void in or extending through the cushion base is formed. A cushion insert such as an air bladder or fluid sack is positioned within the void. A lip or upper surface around an opening in the void overhangs at least a portion of the cushion insert, thereby minimizing the size and corresponding negative effects of a transition area where the base and the insert overlap.

A system for use with a mobile device includes at least one sensor to sense a variable related to tilting of the mobile device and at least one activatable system in operative connection with the sensor. The at least one activatable system increases stability of the mobile device upon actuation/change in state thereof on the basis of data measured by the at least one sensor. A variable related to tilting includes variables that indicate concurrent, actual tilting as described herein as well as variables predictive of imminent tilting. Activatable systems hereof change state upon actuation or activation to increase stability of the mobile device by reducing, eliminating or preventing tilting.
