Definitions

  • the present invention relates to a device for hingeably connecting backrests of seats and the like to the associated frame, comprising at least one spring spiral with opposite arms which are respectively fixed to said backrest and frame.
  • hinging systems for backrests of chairs which systems, although serving their purpose, have a complex and costly structure and an aesthetic appearance which does not blend in with the design of the chair.
  • the technical problem which is posed, therefore, is that of providing a hinging device for backrests of chairs which is structurally simple and reliable and consists of a small number of parts which can be easily assembled and applied to any type of chair, armchair and the like with or without arm-rests.
  • the hinging system should have a certain degree of elasticity so as to provide the backrest with a slightly springy action.
  • a device for hingeably connecting backrests of chairs and the like to the associated frame comprising at least one spring spiral with opposite arms which are respectively fixed to said backrest and frame.
  • the hinging device comprises two pairs of wires 1 which are made of steel or similar material and each of which is twisted so as to form a spiral 2 of a spring with opposite arms 3 and 4 which are respectively fixed to the frame 5 of the chair and to an element 6 supporting the backrest 7 of the chair itself.
  • Each arm 4 fixed to the backrest 7 is provided with a threading 4a.
  • Said element 6 supporting the backrest 7 has a shape substantially in the form of an "L" with the horizontal short arm having a hole 6a for engagement with the threading 4a of the arm 4 of the spring, being fixed thereon by known means such as a weld or a transverse grub screw 6b inserted into the short arm itself until it interacts with the threading 4a.
  • the vertical long arm 6c of the support element 6 has a hole 6d for receiving a screw 8 locking the support 6 of the backrest 7.
  • the arm 3 of the spring inserted into the frame 5 is in turn locked onto the latter by means of a transverse grub screw 5a.
  • a guide bush 9 is also arranged in the region of the hole where the arm 3 enters into the frame 5.
  • the device could be reduced to a single spiral with arms 3 and 4 which are directly inserted into the frame 5 and into the backrest 7 without the need for intermediate elements.
