Description

Technical field [0001] The invention relates to an electric chair, more specifically, to a mechanical extension device for an electric chair with a headrest flipping movable sofa. Background technique [0002] At present, the existing mechanical extension device of the movable sofa electric chair is complicated in structure and generally does not have a headrest turning device, or the headrest turning device and the movable sofa electric chair mechanical stretching device move separately. In summary, there are the following 3 shortcomings : 1. The structure of the mechanical extension device is complex, which is not convenient for mold development and mass production, and the production and manufacturing cost is high; 2. The flipping headrest and the movable chair mechanical extension device are not linked, and two electric devices are required to drive separately, which is not convenient for the headrest The morphological change is compatible with the posture change of the mova...
