Abstract: The present invention provides an assembly that is configured to assist a user sitting into and/or rising from a wheelchair. In one embodiment, each assembly has a mount configured to affix the housing of a respective assembly to a corresponding first or second arm of the wheelchair. A pivotable arm extends from the housing to a user grip, wherein the pivotable arm is configured to rotate about a longitudinal axis of the housing. A ratchet lock disposed within the housing is configured to engage the pivotable arm extending from the housing and provide the pivotable arm with at least three locking positions, and a linkage is configured to selectively disengage the ratchet lock upon user activation. Rotation of the pivotable arms allows the user grip to rotate from a raised position, an outer position or a lowered position. In another embodiment, the assembly is integrated into the arm tube of the wheelchair.

Abstract: A charging device for use with a door assembly is described. The charging device for use with a door assembly is configured to convert kinetic energy of linear motion to electromotive force and includes a rechargeable power source coupled to the charging device, wherein the linear motion is caused by movement of the door assembly to charge the rechargeable power source. Also, a charging device and method for wirelessly charging an electrical storage device on a door assembly includes a transmitting coil positioned proximate a door assembly and a receiving coil positioned on a door assembly for inductively charging the electrical storage device and for powering a senor for wirelessly sending an alert signal.
