Belt driven width expansion of a bed

A bed comprising

• an articulated bed deck configured to support an occupant, the articulated bed deck including a first deck section and a second deck section, the first deck section being pivotable relative to the second deck section, the first deck section including a first fixed width portion and a first pair of wings movably coupled to opposite end regions of the first fixed width portion, the second deck section including a second fixed width portion and a second pair of wings movably coupled to opposite end regions of the second fixed width portion,
• a first pulley situated outside a footprint defined by the articulated bed deck and spaced apart from an end of the articulated bed deck, the first pulley being mounted to the first deck section for rotation about a pulley axis that extends beneath the first deck section, wherein the first pulley pivots with the first deck section relative to the second deck section as the first deck section pivots, and
• a pair of belts trained about the first pulley, the pair of belts and the first pulley being operable to extend and retract the first and second pairs of wings relative to the first and second fixed width portions, respectively, to increase and decrease, respectively, a width of the articulated bed deck, wherein the bed is devoid of any pulleys within the footprint defined by the articulated bed deck.
