1. A deployable headrest assembly for a seat, comprising:
- a headrest slidably coupleable to the seat and movable from a stowed position, in which the headrest is stowed within a seat back of the seat, to a deployed position, in which the headrest extends from the seat back,wherein the headrest is expandable from a collapsed state to an expanded state such that the headrest has a thickness that is larger in the expanded state than in the collapsed state, the headrest being retractable into the stowed position in the seat back when in the collapsed state;
wherein the headrest comprises a collapsible structure configured to collapse and expand between the collapsed and expanded states; and
wherein the collapsible structure comprises a flexible membrane and a plurality of wedge-shaped members sequentially arranged on the flexible membrane such that non-parallel wedge surfaces of the wedge shaped members are in successive engagement to define a curved surface when the headrest is in the expanded state.
