Definitions

  • This invention concerns a seat which can be extended forwards.
  • the invention concerns also seats, such as armchairs or divans with places for one or more persons, which can be extended forwards with their supporting surface extending along their whole length.
  • the known systems consist usually of various kinematic mechanisms, some of them complex, which are burdensome to manufacture and often hard to operate and are likely to cause maintenance problems.
  • the present applicant has designed, tested and embodied a very simple device which enables the seating surface of seats such as armchairs and divans to be extended forwards.
  • the invention provides essentially for two movable frames, of which the first is rotatably pivoted at its sides in a substantially intermediate position on the side members of the stationary framework that forms the fixture structure of the seat.
  • This first frame which has its disengaged end towards the front of the seat when the seat is folded shut, is hinged to a second frame, which in the folded state of the seat is positioned above and parallel to the first frame.
  • the extended position of the seat is obtained by rotation of the first frame about the pivot which anchors it rotatably to the side members of the stationary framework.
  • the rear end of the first frame becomes the forward end, and the first and second frames together form a succession and lie substantially on the same plane.
  • a movable seatback extension element which is connected to the first frame and is able to take up a first and second position.
  • the first position is obtained with the seat folded shut and is substantially vertical or almost vertical
  • the second position is obtained with the seat opened and is substantially horizontal or almost horizontal.
  • reciprocal momentary clamping elements are provided to avoid any danger to a person using the chair owing to the unstable zone of rotation of the first frame when the seat is opened.
  • the extensible seat is therefore embodied according to the contents of the main claim and one or other of the dependent claims.
  • a seat 10 comprises a seat structure 12, which forms the seating platform and can be moved and extended forwards, and also a first frame 15 and second frame 16, the frames 15-16 being substantially, but not necessarily, the same as each other.
  • the frames 15-16 comprise in a known manner an intermediate support structure 33 to which cushions 121 and 21 respectively are applied.
  • the movable seat structure 12 cooperates with side members of a stationary framework 11 that includes a seatback 19 and feet 14.
  • a suitable cushion 20 is located against the seatback 19.
  • the first frame 15 includes at its sides in an intermediate position a first pivot 13, which connects it to the framework 11 and enables it to rotate.
  • the first frame 15 is connected at one end by a hinge 17 to the second frame 16,, so that in the closed position (Fig.2) of the seat the two frames 15-16 are rested against each other, and surfaces 18 which bear respective cushions 121 and 21 diverge as counterparts of each other.
  • the second frame 16 comprises support feet 114 which are parallel to the feet 14 of the stationary framework 11 when the seat 10 is in its closed position.
  • the pivot 13 can be located in a displaced position (Fig.5), so that, when the first frame 15 is rotated, the latter 15 is raised and creates a higher resting surface or a surface at the height of the previous surface obtained with the second frame 16 in its closed position.
  • the seatback 19 comprises a movable extension element 22 pivoted on a second pivot 25, it is possible to connect such extension element at a third pivot 24 to a tie rod 23.
  • the tie rod 23 is connected by a fourth pivot 124 to the first frame 15; in the example shown the fourth pivot 124 is located at an intermediate position between the first pivot 13 and the hinge 17.
  • the movable extension element 22 is positioned in one of two positions, a first closed position where the movable extension element 22 is substantially vertical or almost vertical, and a second open position where the movable extension element 22 is substantially horizontal or almost horizontal (Fig.5).
  • the invention provides a variant in which spring catches 29 are included and secure the first frame 15 momentarily by preventing its rotation.
  • the movable seatback extension element 22 may comprise vertical retention means 26 for the seatback cushion 20.
