Abstract

A device for supporting a patient, having a carrying member and a horizontally extending lying support for the patient, with a motor for varying the distance between the support and a medicinal unit. The invention is particularly characterized by the provision of a spring scale between the patient support and its carrying member, having a switching member which can be shifted corresponding to the weight of the patient. Switching means are connected with the switching member for interrupting the current circuit of the motor, the distance between the switching means and the switching member being adjustable.
