A sport-wheeled chassis is provided for connecting to a mobility device, which comprises a suspension set up under the bottom of the mobility device, a steering pivotally connected to the suspension, a controller connected to the suspension and steering electrically, tires which are pivotally connected to the steering and disposed under the steering, and a steering shaft of the steering which coincides axially with the steering shaft of the tire so that the controller can operate the turning direction of the tire and the height of the suspension through the suspension and the steering. The chassis is not only with a simple structure, but also with a suspension to control the height of the chassis off the ground, so that the chassis can maintain stability in any rugged environment, and, with its attached wheels, the chassis can move to desired places fast and accurately.

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.

A chassis for a tracked mobility device may include: a battery box floor; a battery box rear wall; a pair of main side rails; a main front cross member; a lower box rear cross member; a pair of side bogie support tubes; a pair of motor support tubes; rear side support tubes; front side support tubes; a pair of bogie support plates; short bogie cross tubes; seat frame plates; a tensioner support frame; a rear cross support plate; motor/gear boxes having floors, rear walls, outer side walls, inner side walls, and outer side wall extensions/gussets; anti-tip tubes; anti-tip cross-members; and anti-tip vertical tie rods. The chassis components may be welded together to provide a rigid, stable, unitary construction.

The present invention relates to a human-propellable vehicle comprising a chassis and a footplate for receiving a rider's feet. The footplate is movably mounted to the chassis so that at least part of the footplate can be deflected up towards the rider in the event of a collision between the underside of the footplate and an object or terrain passing under the chassis.

The present disclosure relates to a chassis arrangement (1) for an electrically powered wheelchair (35). The chassis arrangement (1) comprises a main chassis member (3) having a first side panel (3a) defining a first side of the main chassis member (3), and a second side panel (3b) defining a second side of the main chassis member (3), the second side being opposite to the first side, wherein each of the first side panel (3a) and the second side panel (3b) has spring attachment arrangements (3g, 3h) for attachment of spring assemblies (9a, 9b, 11a, 11b), wherein each of the first side panel (3a) and the second side panel (3b) has pivot arm attachment arrangements (3e, 3f) for attachment of pivot arms (5a, 5b, 7a, 7b), wherein the main chassis member (3) has a torsional stiffness greater than 1200 Nm/degree. An electrically powered wheelchair comprising a chassis arrangement (1) is also presented herein.

A seat for a stair lift, which seat is provided with a fall protection device comprising at least one elongate safety bar which is movable between an open position and a closed position, in which open position a person can freely move into and out of the seat, wherein the safety bar is movably connected to an elongate support that is stationarily connected to the seat, which support extends on a side of the seat, wherein the fall protection device is designed so that in the open position the safety bar takes up a rearward position, in which it extends substantially parallel to and beside the support, and that in the closed position the safety bar takes up a forwardly moved (along the support), inwardly pivoted or rotated position, in which it extends from the front end of the support, in which position it can be locked, such that a person cannot fall out of the seat.

A wheelchair including a frame and a suspension system. The suspension system may have at least one front caster arm pivotally connected to the frame, a front caster connected to the front caster arm, a first link, and a second link. The first link is pivotally connected to the frame, and the second link is slidably connected to the front caster arm and pivotally connected to the first link.
