This creation is a rollover auxiliary device, which includes a base, a bed frame and a plurality of buffer structures, the bed frame includes a frame body and a pivot shaft, the pivot shaft is pivotally connected to the base, The frame system is arranged on the pivot shaft and extends in an arc shape toward the two sides. The plural buffer structures are arranged between the base and the bed frame and distributed on the pivot shaft of the bed frame On the opposite sides, the bed frame of the roll-over assist device of the present invention can pivot relative to the base according to the change of the center of gravity, and cooperate with the multiple buffer structures to provide a buffer effect, so that the user can easily perform the roll-over action, thereby reducing the caregiver assistance to the patient Or the burden of the elder when performing the rollover.本創作係一種翻身輔助裝置,其包含一基座、一床架及複數緩衝結構,該床架包含一架體及一樞接軸桿,該樞接軸桿係樞接於該基座上,該架體係設置於該樞接軸桿上並朝二側向上呈弧曲狀延伸,該複數緩衝結構係設置於該基座與該床架之間,並分布於該床架之樞接軸桿相對二側,本創作翻身輔助裝置之床架能依據重心變化而相對該基座樞轉,並搭配該複數緩衝結構提供緩衝效果,讓使用者能便於進行翻身動作,進而減輕照護人員協助病患或年長者進行翻身動作時之負擔。
