The invention relates to a turnover hinge structure, a seat widening armrest and an automobile seat. The structure comprises a first hinge part, a second hinge part, a first direction rotating shaft and a second direction rotating shaft, wherein the first direction rotating shaft and the second direction rotating shaft are sleeved with elastic reset pieces; the first hinge part comprises at least two first hinge plates; every two adjacent first hinge plates are hinged through a second direction rotating shaft; the second hinge part comprises at least two second hinge plates; every two adjacent second hinge plates are hinged through a second direction rotating shaft; each first hinge plate is hinged to the corresponding second hinge plate through a first direction rotating shaft. By the adoption of the overturning hinge structure, the seat armrest can be widened and enlarged, the requirement for the arm pressing range of a passenger is met to a greater extent, and the comfort of the passenger is better provided. The hinge structure is simple, low in cost, short in implementation period, convenient to operate and high in practicability.
