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.
