Abstract
The invention is with respect to a stretcher for ambulances. The stretcher has a backup or retainer cushion for keeping a patient in position when acted upon by jerks or by sudden motion in the length-direction of the ambulance. The backup cushion is united with a safety belt, which is so placed on the patient that the patient is kept in position in relation to the stretcher when suddenly jerked in the length-direction. In the case of one form of the invention, the backup cushion is elastically supported so that the body of the patient is not suddenly slowed down. As part of a useful further development of the invention, the backup cushion is joined with a fixing belt, which, for its part, is drivingly joined up with the lock or ratchet of an automatic belt take-up roller or pulley. This roller itself has a safety belt which, on loading the stretcher onto a stretcher support of the ambulance, is joined up with the floor of the vehicle, more specially automatically. The design is such that, when the fixing belt is acted upon by a sudden pulling force on decelerating at more than a certain rate, the automatic belt roller is locked by way of the lock. Because of this, the patient and the stretcher are safely kept in position. The design may furthermore be used in connection with stretchers designed as day-beds.
