Detailed Description
The general-purpose type upholstered armchair according to the present invention will be further described with reference to figures 1 to 2.
A general sofa backrest frame is characterized in that: comprises a frame body 1 and a supporting component 2. The frame body 1 comprises two vertical plates 11 which are arranged in parallel and used for installing the supporting component 2 in an upright or inverted state. The supporting component 2 comprises a fixing plate 22, a connecting rod 21, an electric push rod 23 and a supporting plate 24; the two fixing plates 22 are arranged in parallel, and the two fixing plates 22 are arranged on the two vertical plates 11 in an upright or inverted state; the connecting rod 21 is arranged between the first ends 221 of the two fixing plates 22; the supporting plate 24 is rotatably connected between the second ends 222 of the two fixing plates 22; the electric push rod 23 is hinged to the connecting rod 21, and the push rod of the electric push rod 23 is connected with the support plate 24 to drive the support plate 24 to rotate so as to adjust the angle of the support plate 24.
Based on above-mentioned structure, when the installation, can be according to user's user demand, be upright state with supporting component 2 and install between two risers 11, make backup pad 24 correspond with user's head, with backup pad 24 as the headrest that supplies user's head to support, or be inverted state with supporting component 2 and install between two risers 11, make backup pad 24 correspond with user's back, with the back that uses backup pad 24 as the back that supplies user's back to support, have simple to operate and the high characteristics of flexibility.
The support plate 24 is provided with a connection hole through which the support plate 24 can be connected to a headrest frame or a back support frame.
