An auxiliary drive device for a wheelchair has at least one freely pivotable electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The coupling mechanism includes a movable locking element which is movably supported in the coupling mechanism. The movable locking element can be in a locking position in which it causes locking in a positive-locking manner so that the auxiliary drive device is coupled to the wheelchair and, by operation of a handle, the locking element can be moved in a release position in which uncoupling of the auxiliary drive device from the wheelchair is possible.

A seat for a mobility device accommodating flexibility, personalized comfort, and transportability. The seat can include a button push means to enable movement of a height-adjustable armrest. The seat back can fold upon the seat for transportability. The seat cushion and armrest cushion can be removably mounted and separately replaceable. The seat can be mounted upon various types of devices, including, but not limited to, wheelchairs.

A patient support apparatus includes a frame, a stationary member mounted relative to the frame, a movable member having a pivot member rotatably mounting the movable member about the stationary member, and a fastener securing the pivot member to the stationary member. The patient support apparatus also includes a joint between the pivot member and the stationary member, which is configured to apply a tension force on the fastener.

An external structural brace apparatus for supporting a user in a semi standing position on a surface includes first and second support extension beams that to attach to the surface, also included is a channel having a base with first and second legs, wherein the first and second legs extend in the same direction from opposing sides of the base, the first leg is affixed to the first support structure and the second leg is affixed to the second support structure, the channel can be lockably positioned along the first and second beams. In addition, a saddle seat with a midpoint extension portion, the saddle is attached between the first and second legs and positioned such that the midpoint extension extends opposite of the base, wherein operationally the user partially rests their buttocks on the saddle and leans their back against the base to assume a semi supported standing posture.

An exoskeleton wheelchair system includes a base, one or more wheels coupled to the base, a body support connected to the base comprising: a back support; and one or more leg supports pivotally coupled to the back support, and a gait wheel linked with the one or more leg supports via one or more gait linkages and configured to rotate the one or more leg supports. The one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode. The back support is maintained at a fixed position relative to a location of the base when the one or more leg supports pivot about the first axis while the back support is in the standing position mode.

A transport chair of this disclosure includes a frame having a pair of fixed sides and hinged sides, the frame moveable between stowed and deployed states. The frame includes wheel receiving means and armrest and push handle assemblies receiving means with quick connect-disconnect clamps or pins. A bar, which is connectable to, and detachable from, each hinge extends between the pair of hinged sides. When connected to the hinged sides, the bar locks the frame in the deployed state and prevents the frame from moving to the stowed state. The chair may be quickly assembled and then dissembled for storage without the need for tools. When dissembled, the transport chair fits within an envelope 9 inches deep×14 inches wide×22 inches long.

A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The user is able to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.
