PROBLEM TO BE SOLVED: To have a meal or the like in safe while preventing a body from laterally falling down by wrapping the waist of a human body by pushing up a pair of left and right holder parts, which are pivotally attached to one part of a main frame, with a free link 4 while utilizing the back-up mechanism of a nursing bed. SOLUTION: While utilizing the back-up mechanism of the nursing bed, sub frame 23 are attached under a main frame 2 in the shape of diamond. While utilizing a change in the distance between the sub frame 3 and the main frame 2 at the point of changing the angle of the rear part of the bed from a plane, a pair of left and right holder parts 1 pivotally attached to one part of the main frame 2 by a hinge are pushed up by a free link 4 and the waist part of the human body is wrapped together with a mattress on the bed so that the body can be prevented from laterally falling down. Since the holders are formed for wrapping the waist from both sides simultaneously with back-up, the body is stably held and mealing can be easily performed in safe. |
