Seat Bracket and Zero Wall Recliner Having Seat Bracket

A seat bracket, wherein the seat bracket comprises:

• a linkage mechanism, comprising a bracket side plate and a linkage assembly, wherein the bracket side plate has a seat frame mounting surface, and the linkage assembly is hingedly connected with the bracket side plate;
• and
• a backrest mechanism, comprising a backrest mounting plate and a backrest linkage assembly, wherein a front end of the backrest mounting plate and a rear end of the backrest mounting plate are hingedly connected with the bracket side plate and the linkage assembly, respectively, via the backrest linkage assembly, the backrest mounting plate has a retracted position in which it is retracted relative to the bracket side plate and a reclined position in which it is inclined rearward relative to the bracket side plate, and the linkage mechanism is capable of driving the backrest mounting plate to switch between the retracted position and the reclined position via the backrest linkage assembly;
• wherein when the backrest mounting plate is in the retracted position, the rear end of the backrest mounting plate is located at point A, and the front end of the backrest mounting plate is located at point B;
• when the backrest mounting plate is in the reclined position, the rear end of the backrest mounting plate is located at point C, and the front end of the backrest mounting plate is located at point D;
• a line connecting the point A and the point C is a connecting line L1, and a line connecting the point B and the point D is a connecting line L2;
• an intersection of a perpendicular centerline of the connecting line L1 and a perpendicular centerline of the connecting line L2 is point F;
• when the backrest mounting plate switches between the retracted position and the reclined position, a distance between the point F and the seat frame mounting surface is within a preset dimension range, so that a movement trajectory of the point F is within a range of motion of a human lumbar region.
