Abstract: An air valve assembly includes a housing defining an internal channel configured to receive a first member, the first member is fluidly connected to an air source, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, and a sealing member positioned in the internal channel and defining a first inflation aperture, the plunger member slidably received by the first inflation aperture. In a first inflation configuration, the first member is configured to form a magnetic connection with the sealing member and contact the plunger member to overcome the biasing force, the plunger member is configured to responsively slide relative to the first inflation aperture to facilitate a flow of air between the sealing member and the plunger member.

Abstract: A multi-position airflow control assembly includes a valve body fluidly connected to at least three inflation zones of a cushion, a control assembly partially received by the valve body, the control assembly including a seal member, and an actuation assembly operably connected to the seal member and configured to rotate the seal member relative to the valve body between at least a first position and a second position. In the first position, the seal member is configured to fluidly isolate the at least three inflation zones from each other. In the second position, the seal member is configured to group the at least three inflation zones into a first group of inflation zones being fluidly connected, and a second group of inflation zones being fluidly connected, the first group of inflation zones being fluidly isolated from the second group of inflation zones.

Abstract: A seat cushion assembly includes a base defining a leg support and a support portion recessed relative to the leg support, and an air pad assembly positioned on the recessed support portion, the air pad assembly including a plurality of independent air support zones that are configured to be separately inflated and deflated.

Abstract: A multi-position airflow control assembly includes a valve housing, a valve body received by the valve housing, a plurality of connectors coupled to the valve body, each connector configured to fluidly connect to an inflation zone of a cellular cushion, and a control assembly partially received by the valve body. The control assembly includes a seal member, and an actuation assembly operably connected to the seal member and configured to rotate the seal member relative to the valve body. The seal member is configured to rotate between a first position and a second position.

Abstract: An air valve assembly includes a housing defining an internal channel, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, a sealing member defining a first inflation aperture, the plunger member slidably received by the first inflation aperture, a second deflation aperture defined by the housing and in fluid communication with the internal channel, and a deflation control member slidably connected to the housing, the deflation control member configured to selectively seal the second deflation aperture.

Abstract: An adjustable back support for a mobility device includes a first adjustable back support assembly including a first support member and a second support member, and a second adjustable back support assembly. The first support member is moveably connected to the second adjustable back support assembly, the first support member being configured to pivot relative to the second adjustable back support assembly relative to a first axis of rotation, and the second support member is moveably connected to the first support member, the second support member being configured to pivot relative to the first support member relative to a second axis of rotation that is not parallel to the first axis of rotation.
