Definitions

  • the invention relates to a piece of furniture with a frame with a guide that enables a substantially horizontal displacement of a seat relative to the frame, wherein on the frame on the one hand and on the seat surface on the other hand engages a spring element that biases the seat surface in an initial position to the rear, also with a backrest, at the upper end of which a headrest is pivotally attached, which is in operative connection with the seat surface such that when the seat surface is moved forward, the headrest is pivoted forward about a horizontal axis into an approximately vertical position.
  • WO 80/02102 describes such seating.
  • the swiveling, upholstered headrest is connected to the seat surface by a train in the form of a steel band in such a way that when the seat surface is moved forward, the headrest is also pivoted forward from a slightly inclined position, for example into a vertical position. If the seat is moved back to its initial position, the headrest in this initial position again assumes its almost vertical position.
  • the invention has for its object to design a seating of the type mentioned so that the head of a person sitting on the seating in an upright position is not supported, but in the comfortable rest position in which the seat is pushed forward.
  • This adjustment of the swivel position of the headrest to the position of the seat surface should take place automatically, i.e. without the person in question getting up or having to take any other action.
  • the invention is characterized in that the headrest is pivoted to an approximately horizontal position when the seat is moved rearward.
  • the seat and the headrest are connected to one another via suitable mechanical connecting links, so that both movements take place synchronously with one another, without the user of the seating furniture having to do anything besides the aforementioned displacement of the seat against the spring force. If the seat is moved backwards, the sequence of movements takes place in the opposite direction.
  • the movement sequence described is further supported if a spring element engages on the one hand on the backrest and on the other hand on the pivotable headrest, which prestresses the headrest in its upright position.
  • This spring element thus supports the spring element mentioned at the outset, which prestresses the seat surface in the rear starting position.
  • An embodiment is preferred, which is characterized in that a cable is attached at one end to the seat surface and is guided from there via a roller attached to the frame to the pivotable headrest, where it is attached.
  • the cable takes up little space and is characterized by a long service life and low design effort.
  • the fixed roller causes the necessary reversal of movement. This means that when the seat is moved forward, a certain length of cable is released, which, supported by the spring acting on the headrest, causes the headrest to pivot into the upright position.
  • the headrest should be upholstered. To pass the cable through the headrest pad without damaging it, it is preferred if the end of the cable attached to the pivotable roller is passed through a sleeve inserted into a hole in a padding of the pivotable headrest.
  • the attachment of a cushion for the backrest, including the pivotable headrest is preferably carried out in such a way that an insert pocket accessible from the underside is formed in this cushioning in such a way that the cushioning can be pushed from above onto plates which form the backrest and the pivotable headrest.
  • the seating furniture described in the already mentioned WO 80/02102 also has the features that a back cushion resting on a support plate of the backrest has a flatter inclination when the seat surface is displaced relative to the frame or a stronger one when the seat surface is displaced rearward Takes an inclination to the horizontal and thereby constantly supports the lumbar region of a person sitting on the seating furniture, the lower edge of the support plate also being articulated on the seat surface and the upper edge shifting relative to the backrest part of the frame.
  • the backrest is articulated there to the seat and can be pivoted about a horizontal axis relative to the frame. On the back The backrest lies on the support plate, which extends over the entire length of the backrest, or extends beyond it.
  • the support plate is divided into at least two partial plates and supports the entire back of the person sitting on this seating furniture, or additionally the head.
  • a handlebar is hinged at one end to the common pivot axis between the seat surface and the backrest and at the other end at a point approximately in the middle of the lower part of the support plate.
  • This known seating furniture thus offers a very high level of seating comfort, which, however, is purchased with the disadvantage of a relatively complex construction.
  • the backrest part of the frame is firmly connected to the frame and the support plate is not subdivided and only extends over essentially the lumbar region.
  • the support plate extends only over the lumbar region and the upper part of the support plate with one or two additional joints is therefore also eliminated.
  • the lumbar vertebra area is always well supported in the aforementioned shifting of the seat forward or backward, because the support plate bridges the space between the fixed backrest and the forward-moving seat to a certain extent.
  • the back cushion extends in one piece upwards over the support plate and is part of the entire back cushion of the seating furniture.
  • the seating furniture consists of a frame 1 with a frame-fixed, padded backrest 2.
  • a likewise padded seat 3 can be moved horizontally forwards in the direction of arrow 4 or backwards in the opposite direction of this arrow relative to the frame.
  • guides and rollers 5 are provided.
  • a vertically acting gas spring 6 is attached at one end to the frame, while its piston rod 7 engages a rod 9 with an adjustable length via a bent lever 8.
  • the other end of the rod 9 is in turn attached to the seat 3. As a result, the seat is biased into the starting position shown in FIG. 1.
  • a support plate 10 is articulated with its lower, horizontal edge 11 to a frame 12 of the seat 3, quite far at the rear end of the seat.
  • a back cushion 13 rests on the support plate 10. If the seat 3 is moved forward in the direction of arrow 4, the support plate 10 is simultaneously pivoted backwards about the joint 11 into a flatter position and with it the back cushion 13. This bridges, as it were, between the front wall of the backrest 2 and the Back wall of the seat 3 emerging space and well supports the lumbar region of a person sitting on the seating.
  • the pivotable headrest which is articulated to the upper, horizontal edge of the backrest 2.
  • the pivotable headrest consists of a plate 21, the lower edge of which is pivotally connected to the upper edge of the backrest 2 via a horizontally extending joint 22.
  • a gas pressure spring 23 engages on the one hand on the backrest 2, namely on the back, and on the other hand on the back of the plate 21. The gas pressure spring endeavors to move the plate 21 from the initial position shown in FIG. 1 in the direction of arrow 24 to the rest position Fig. 2 to pivot, in which the headrest assumes an upright position.
  • a cable 25 is attached to the upper end of the plate 21, which is guided over rollers 26 attached to the frame and the other end 27 attached to the lower, rear end of the frame 3 is.
  • the backrest 2 and the plate 21 are upholstered with the cushion 13, which has a slot accessible from the underside, so that the cushion can be pushed onto both plates from above.
  • the cushion In the area of the joint 22, the cushion has a fold line on the back.
  • a sleeve 28 is guided on the back of the cushion through a hole provided there.
  • the upper end of the cable 25 is guided through the sleeve 28, which thus protects the cushion there.
  • the spring element with the gas spring 6 and the rod 9 is arranged horizontally to save space. 3 and 4, a guide 29 for the displacement of the seat 3 on the frame 1 is also indicated.
