Publication number: 20190175427Abstract: A patient assisting system includes a frame having a sling assembly attachment point and a lifting arm which is movable relative to the frame and which includes a receptacle. When the sling assembly is attached to the attachment point and extends through the receptacle, a portion of the sling travels through the receptacle as the lifting arm moves relative to the frame. Another embodiment includes exactly one four bar linkage comprised of a frame having an attachment point for a sling assembly, a lifting arm having a receptacle, a lower cross arm and an upper cross arm. The lifting arm is adapted to be movable between a person-seated position and a person-standing position. The receptacle is located along the lifting arm so that motion of the lifting arm causes the receptacle to move along a curved path having a concave side which is person-facing.Type: ApplicationFiled: February 19, 2019Publication date: June 13, 2019Inventors: Anders Joakim Eriksson, Elin K.
