Abstract
An emergency stretcher for emergency vehicles includes an X-frame litter support mechanism that vertically movably supports a patient litter on a wheeled base. Each of the legs of the litter support mechanism have the capability to expand and contract in length, and a fixed-length link member extends between the base and one of the legs. A releasable locking arrangement can releasably lock the patient litter in a selected vertical position, and can be released only when the patient litter is manually lifted. A gas cylinder which controls the angular position of a pivotally supported upper body support member can move into a recess in a cross member of the patient litter.
