Three litter rack systems are disposed on respective walls of the interior space. Each of the litter rack systems is provided with a system for automatically adjusting the vertical position between and tilt of the patient litters in each of the rack systems. Adjustable attendant chairs are placed strategically adjacent the rack systems for attending patients therein.

Abstract: A multi-tiered litter rack system is described generally comprising a plurality of support masts arranged on one wall of an emergency vehicle. The masts support a plurality of vertically spaced litters in at least two horizontally spaced positions. The masts enclose vertical adjustment screws which are adapted to independently adjust the vertical position of each end of the litters for controlling the tilt of and vertical spacing between the litters. The multi-tiered liter rack system further includes individual motors associated with each of the respective masts which are operatively connected to the vertical adjustment screws for controlling the vertical position and tilt of each of the litters.
