  • Patent number: 11903885
    Abstract: A wheelchair armrest storage system may include a housing for a wheelchair, where: the housing includes a proximal portion, a distal portion, a first lateral side, and a second lateral side, the housing extends longitudinally between the proximal portion and the distal portion, and at least one cover receiving cavity is defined in each of the first lateral side and the second lateral side. The wheelchair armrest storage system may further include a storage area defined within the housing, and a cover configured to translate within each of the at least one cover receiving cavity defined in each of the first lateral side and the second lateral side.
    Type: Grant

  • Patent number: 11806289
    Abstract: 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.

  • Patent number: 11096847
    Abstract: An exoskeleton wheelchair system includes a base, one or more wheels coupled to the base, a body support connected to the base. The body support includes a back support, and one or more leg supports pivotally coupled to the back support. The exoskeleton wheelchair system also includes an actuator linked with the one or more leg supports and configured to rotate the one or more leg supports, a processor, a memory module, and machine readable instructions that, when executed by the processor, cause the processor to rotate the one or more leg supports with the actuator. The one or more leg supports pivot about a first axis when the back support is in a standing position mode, and the first axis is maintained at a fixed position when the one or more leg supports pivot about the first axis while the back support is in the standing position mode.
