Combination ambulance cot and chair

A reclinable ambulance cot used to load a patient into the back of an ambulance is provided. The cot includes a wheeled collapsible undercarriage carrying an articulated bed frame comprised of a leg segment, seat segment, and wheeled back segment. The articulated bed frame may be moved between an inclined, fully-reclined position, a chair position, and a plurality of positions therebetween. A lockable biasing device assists in the transition by urging the bed frame segments from the chair position to the fully-reclined position. The back segment further includes a pair of loading wheels at the ends of side extensions such that when the cot is in the inclined, fully-reclined position the loading wheels are at height sufficient to facilitate loading the reclined cot into the back of an ambulance, and in particular, into the back of an ambulance having a high transport deck.
