Foldable chair

An articulable chair, comprising:

• a seat and a back being placed to have at least a first angular position in which an angular distance between the seat and the back is minimum and a second angular position in which the angular distance between the seat and the back is maximum;
• first rotational means configured to define a first axis of rotation and arranged for a first relative angular movement between the seat and the back, the first rotational means being disposed at one end of a side of the seat;
• and
• second rotational means configured to define a second axis of rotation and arranged for a second relative angular movement between the seat and the back, the second rotational means being disposed at one end of a side of the back,
• wherein the first rotational means and the second rotational means are arranged independently with respect to each other for independent angular movements of the seat and the back with respect to each other,
• wherein each of the seat and the back is placed in a substantially vertical position and in a substantially horizontal position as being independently moved using the first rotational means and the second rotational means,
• wherein the articulable chair further comprises a support that includes a first fastening point and a second fastening point to independently connect the first rotational means and the second rotational means to the support, respectively, the support further including a fastening end that is connected to a foundation to fix the articulable chair to the foundation attached to a floor,
• wherein each of the first rotational means and the second rotational means comprises:
• a male plate;
• a rod projecting from a central part of an inner face of the male plate;
• a female plate including a through hole through which the rod is inserted,
• wherein the male plate has protrusions to be embedded in the support in an outer face of the male plate, so that a relative rotation between the male plate and the support is prevented, and
• wherein the rod has relative rotational ability with respect to the female plate and the seat by the female plate being attached in a fixed way to the seat.
