ACTIVE STABILITY DEVICES AND SYSTEMS FOR MOBILE DEVICES

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.

SWING ARM LINKAGE FOR A MID-WHEEL DRIVE WHEELCHAIR
20180008493 · 2018-01-11 ·

The present disclosure relates to a swing arm linkage (1) for a mid-wheel drive wheelchair, comprising: a first swing arm (3) having a first swing arm pivot point (3a) and a linkage member first mounting point (3b), a second swing arm (5) having a second swing arm pivot point (5a) and a linkage member second mounting point (5b), a linkage member (7) configured to be connected to the linkage member first mounting point (3b) and to the linkage member second mounting point (5b), to enable force transfer between the second swing arm (5) and the first swing arm (3), wherein the linkage member (7) has an elongated shape defining a linkage axis (A) extending between the linkage member first mounting point (3b) and the linkage member second mounting point (5b), a first straight line being formed between the first swing arm pivot point (3a) and the linkage member first mounting point (3b), and a second straight line being formed between the second swing arm pivot point (5a) and the linkage member second mounting point (5b), wherein the linkage member first mounting point (3b) and the linkage member second mounting point (5b) are so arranged relative to each other that the sum of an angle α between the linkage axis and a line perpendicular to the first straight line and extending from the linkage member first mounting point and an angle β between the linkage axis and a line perpendicular to the second straight line and extending from the linkage member second mounting point is constant or increasing with increasing ditch angle.

MOBILITY ASSISTANCE DEVICE WITH TENSIONER
20230029427 · 2023-01-26 ·

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a pivotable securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame; a wheel coupled to the first and second frames; a brake coupled to the wheel to provide friction to the wheel when actuated; and a tensioner coupled to the brake to adjust cable tension during wheel braking.

Stability control system

Embodiments of a suspension for a vehicle is provided. The suspension includes, for example, a frame and a locking assembly. The locking assembly inhibits tipping of a frame of the vehicle when tipping of the frame is detected.

Patient support apparatus adaptable to multiple modes of transport

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus.

AUTONOMOUS MOBILITY SYSTEM

An integrated and autonomous mobility system for disabled persons including an automated wheelchair (AV) and an Adapted Automated Vehicle (AAV) configured to work together as an integrated unit to transport a user to a pre-selected destination with little to no input from the user during the trip. The AV is also configured to operate independently of the AAV to transport the user on shorter trips, or to continue a journey after the AAV has transported the AW to an intermediate destination. Multiple safety systems are included. The system has an override function according to which a user can interrupt the automated transport operation and cause the AV and/or AAV to stop, slow down, speed up, or change direction.

Wheelchair suspension

A suspension for a vehicle is provided. The suspension includes, for example, a frame, at least one drive assembly and at least one caster pivot arm. The at least one drive assembly and the at least one caster pivot arm are pivotally connected to the frame at a common pivot axis such that the drive assembly and the front caster pivot arm are pivotable relative to one another.

MOBILITY SUPPORT DEVICE WITH STEP CLIMBING MECHANISM
20230106280 · 2023-04-06 ·

A mobility support device capable of stably climbing a step without impairing mobility on flat ground is provided. The mobility support device includes a front wheel, a rear wheel, a drive wheel disposed between the front wheel and the rear wheel, a first link coupled to the front wheel, a second link connecting the drive wheel and the rear wheel, a rotation joint coupling the first link and the second link at a first position, and a first elastic member coupling the first link and the second link at a second position different from the first position.

Electric Wheelchair Frame
20170367912 · 2017-12-28 ·

An electric wheelchair frame includes a frame and a power support swayably connected to a frame. A connecting rod is swayably connected to the frame, is pivotably connected to the power support, and is movable relative to the power support in a longitudinal direction. A driving device includes a connecting seat and a power output unit. The connecting seat is pivotably mounted to the power support. The power output unit is fixed to the connecting seat and includes a driving shaft extending away from the frame and a driving wheel. When the driving wheel is moving on a bumpy road, the pivotal movement between the connecting seat and the power support increases the sitting comfort of a user in an electric wheelchair.
