Abstract
A seat includes a seat portion with an air bladder having an outer casing. Multiple fluidly interconnected cells are disposed within a cavity of the outer casing and are configured to inflate the outer casing from a deflated condition to an inflated condition. The cells may be arranged within the air bladder so as to provide a directional inflation of the air bladder from a first portion of the air bladder towards a second portion. First and second support substrates may be disposed within the seat portion, wherein the air bladder is positioned between the first and second substrates. The air bladder may be configured to inflate and displace the first and second substrates relative to one another from an at-rest position to an actuated position. A biasing mechanism may be coupled to at least one of the first and second substrates for biasing the substrates towards the at-rest position.
