  • Patent number: 10765587
    Abstract: A walker adapted for attachment to a wheelchair may be used to assist a user with walking while retaining the wheelchair in close proximity behind the user for use when the user needs to sit. The walker may be removably attached to the frame of the wheelchair for easy exchange of use from one wheelchair to another. A pivotable, removably attachable gate between two vertical rods may allow for the walker to be manipulated from a walking position to a stored position. The gate may include an extendable width to allow for use with wheelchairs of different widths. Telescopic supports may attach the walker to the wheelchair, thereby allowing the user to extend and retract the walker between the walking position and the stored position.

  • Patent number: 10736799
    Abstract: A power assist apparatus that converts a hand-propelled wheelchair to a motorized wheelchair without the use of tools or mounting brackets. The apparatus has a frame, a battery, a control mechanism, a pair of motorized sections at each end of the frame and an outrigger assembly, pivot mechanism and position sensor associated with each motorized section. The motorized sections each have a wheelmotor and a wheel. The outrigger assemblies have arms that support the drive wheels of the wheelchair above the surface to be traversed. The position sensors determine pivoting movement of the outrigger assemblies in response to rotation of the drive wheels by the occupant and transmit positional data to the control mechanism, which sends control information to operate the motors and move the apparatus and wheelchair in the direction indicated by the drive wheels, thereby controlling movement of the apparatus in the same manner as the non-motorized wheelchair.

  • Patent number: 10046677
    Abstract: A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. One or more sensors can each measure an aspect of motion. A processor can (i) receive input from each of the one or more sensors, (ii) determine from this input a measure of rotation of the vehicle away from a nominal, level horizontal orientation, and (iii) utilize the input to determine a desired rotation of the seat. An angle that the seat has been rotated away from a nominal, level orientation is more than insubstantially larger than an angle that the vehicle has rotated away from a nominal, level horizontal orientation.

  • Patent number: 8991849
    Abstract: A sliding arm mechanism for attaching to an arm of a wheelchair is provided herein. One concept is directed to a sliding arm mechanism that includes a main portion and an inner cavity. The sliding arm mechanism also includes a slide rail, which is adapted to be housed within the inner cavity of the main portion. The slide rail and the main portion are slidably coupled to allow the main portion to move laterally over the slide rail in a direction parallel to the top part of the arm of the wheelchair, thus allowing the main portion to move between a first position and a second position. In some embodiments, the first position corresponds to a full-length position and the second position corresponds to a desk-length position, such that a user can adjust the sliding arm mechanism to access a desk or table.
