Abstract
A multifunctional side pillow assembly is provided, including two rotating blocks and two side pillows. The side pillows are slidably disposed on outer walls of the rotating blocks through fixing frames and sliding grooves. Each fixing frame is slidably disposed on the corresponding rotating block through an adjusting assembly in a limited manner, and a clamping assembly is elastically disposed on the fixing frame for increasing a sliding friction on the rotating block. The side pillow slides along the outer wall of the rotating block through the fixing frame; when the limiting block is detached from a limiting groove, a limiting spring is thereby contracted, and then the limiting block slides and a spring block also slides; and when the limiting block slides to another limiting groove, the limiting block is clamped therein under an action of the limiting spring.
