Abstract: An armrest assembly includes a body portion having a cushioned component, wherein the cushioned component includes first and second portions spaced-apart from one another. The cushioned component includes a porous lattice matrix. A duct assembly includes a main inlet and first and second outlets that are operably coupled to the first and second portions of the cushioned component, respectively. The duct assembly further includes first and second channels fluidically coupled to the first and second outlets, respectively. An air diverter member is pivotally supported between first and second positions and includes a channel disposed therethrough. The channel of the air diverter member opens into the first channel when the air diverter member is in the first position, and opens into the second channel when the air diverter member is in the second position for directing airflow to the first and second outlets, respectively.
