Patent number: 12207731Abstract: In a sofa seat stretching device, one end of a second support facing away from a first support, and a second leg rest plate connector are hinged at a fourth hinge point, so that the stretching assembly's stretching speed is reduced in a process of switching from a sitting position state to a lying position state when a driving assembly acts in the same way, and the weightlessness feeling can be effectively avoided. Moreover, the driving assembly drives the stretching assembly so that the process of switching the stretching assembly from the lying position state to the sitting position state is smoother.Type: GrantFiled: November 16, 2021Date of Patent: January 28, 2025Assignee: DEWERTOKIN TECHNOLOGY GROUP CO., LTD.Inventors: Liming Yang, Qiqi Ye, Bin Shen, Kangming Tao, Hanhao Tu
