Abstract: A patient support sling for use with lifting apparatus for transferring a patient between supine and sitting positions has an elongated central seat panel attached at its ends to respective transversely extending thigh and back support panels, and a security panel fastened at the joint between the seat panel and the thigh support panel. The security panel is adapted to be received between the legs of the patient and to engage the patient's chest. Strap members are connected to the rear of the back support panel and are adapted to be looped over the shoulders of the patient and secured to buckle members attached to the security panel so as to draw the security panel against the chest of the patient. The sling provides security to the patient against falling as he or she is being transferred by the lifting apparatus. Additional strap members are disclosed for providing additional security in retaining the patient in the sling.
