  • the present invention concerns a support made of a single piece for supporting the seat of chairs, easy chairs or the like, particularly in cases in which the said seat is formed by a single piece of laminated plastics material.
  • the support is formed by a plurality of brackets extending from a centre block associated with the base of the chair and terminating on both sides in a continuous strip for supporting the seat on both side edges thereof, substantially without the necessity of the provision of vertical connections except for secondary operations such as raising, swivelling and the like.
  • Each chairs formed by a seat or body of stamped-out laminated plastics material, injection-moulded or the like, with an integral back and having a column-like base with legs or the like, of any suitable material, are already known.
  • the support according to the present invention minimizes the said disadvantages and also permits a simple and economical construction with the possibilities of adaptation to various types of chairs, with or without arms, with small writing tables, with a centre column or side legs and the like.
  • a comprising an integral support including a horizontally extending hub in the vertical plane of symmetry of the chair, two sets of brackets extending laterally from the hub and arranged symmetrical in respect of the plane, and two strips extending substantially horizontally and parallel to the plane.
  • Each strip interconnects the outer ends of the brackets of a respective one of the sets and has an upper support surface.
  • the chair seat has turned-down lateral edges extending substantially v horizontally and parallel to the plane. The lateral edges are shaped to conform to the upper support surfaces of the strips and the seat edges engage the support surfaces for support of the seat on the strips.
  • the support brackets of the side supporting strips have a concave portion, the upper profile of the brackets having the same curvature as the area of the seat to be located above them, so that the seat itself, under the action of a load, is also supportable on said brackeis.
  • the two side strips preferably have points of connection for any arms, for the support of the writing table,
  • the body forming the seat and the back in a single piece of stamped-out laminated plastics material has all around its periphery a turned down edge with a substantially horizontal plane surface extending along the parallel side edges corresponding to the position of said two strips connected to the ends of the brackets.
  • the body is slipped on said support, and is located thereon by the turned down side edges on the continuous strips on the ends of the support and may be connected thereto by means of screws or the like for preventing swinging or upward movements.
  • the surface of the body forming the seat can rest substantially directly on the whole length of the brackets of the support, which, as stated, are curved to form a cradle for the distribution of load bearing on the seat, leaving, for the natural distribution of elastic deformation, the possibility of a correct distribution without concentrations of forces of connecting points under load.
  • FIG. 5 is a schematic view of a chair showing the use of divergent legs.
  • FIG. 6 is a schematic view of a chair showing the use of an arm rest.
  • the chair is formed by a base 1 which may be of any known type, and a column 2, also known, from which a shaft extends, said shaft being fixed, displaceable and/or adjustable and on which shaft there is located a support 3.
  • the seat 4 with associated back is mounted on the support, as will be described hereinafter.
  • the support of the seat 4 comprises a hub 5 provided with a tapered bore 5a for connection to the shaft of the column 2, from which extend, integral with hub 5", a plurality of brackets 6, 7, 8, 9, 10, 11 and 12.
  • the brackets are arranged symmetrically in respect of hub 5 and extend forwardly, in the manner of spider legs.
  • brackets 13 and 14 are connected, preferably integrally to strips 13 and 14 extending substantially parallel to the centre axis of the chair and substantially in a horizontal plane.
  • the strips 13 and 14 have an upper plane or slightlyv curved portion 13a and 14a extending over the entire length of the strips and ending in a rear curvature 15 (see FIG. 4) conforming to the bend existing between the seat and the back.
  • the portion of the brackets extending from the central hub 5 follows a curve 16 symmetrical to the centre axis of the support 3, rising at the ends to reach the level of the surfaces 13a and 14a.
  • FIG. 2 shows both the support 3 and the seat 4 according to the invention.
  • the seat for the sake of clarity, is shown in a raised position from the associated support so as to show both the area of support and connection with the support, and all the area in which the user is seated.
  • the seat 4 is provided on both sides with turned-down side edges 17 and 18 corresponding to the strips 13 and 14 having a crosssection and length equal to that of the correstrips l3 and 14 particularly in the upper surfaces 13a and 14a.
  • the centre portion 19 of the seat 4 has the same curvature as the upper part of the support brackets so that, when the seat unit is mounted on the associated support, the bottom of the seat is in contact with or slightly spaced from the brackets.
  • the strips 13 and 14 are provided with holes 20 and 21 through which screws or the like pass for connection to the seat 4.
  • the support of the present invention permits the direct connection of the seat 4 to suitable support strips 13 and 14, the securingthereof and, hence, the slipping of the unit on the shaft of the column 2 which is inserted in a taper bore a of the hub 5.
  • the chair is already complete.
  • anns 24 may also be applied to produce an easy chair or the like, or the writing table parts 25 and 26 may be mounted on the chair. The same parts may be immediately removed by operating in the opposite direction.
  • a chair having a vertical plane of symmetry and comprising, in combination,
  • an integral support including a. a horizontally extending hub in the vertical plane of symmetry,
  • brackets extending laterally from the hub and being arranged symmetrical in respect of the plane, the brackets having outer ends, and
  • the lateral edges being shaped to conform to the upper support surfaces of the strips and the seat edges engaging the support surfaces for support of the seat on the strips.
  • the chair of claim 1 further comprising a central support column supporting the hub.
