Description

The invention relates to a chair with side panels, a backrest and a backrest having at its upper end a pivotable head part, which is connected to the backrest via a pivoting mechanism and is pivotable from a horizontal position to a vertical position and vice versa.

With comfortable seating furniture, the backrest is often extended beyond the shoulder support with a headrest supporting the head. The headboard is rigidly connected to the backrest or variable position to the backrest with a frame, side panels, a backrest or with the backrest of the chair movably. There are chairs known with a tilt-adjustable backrest and with respect to the backrest pivoting headboard, in which the backrest and the headboard are connected to each other via a pivoting mechanism. Thus, the position of the headrest and the inclination of the backrest are coupled together. An example is the utility model DE 89 04 775 U1 directed.

The DE 89 04 775 U1 discloses a reclining chair with a seat pushed forward a bit forward and with a seat back coupled to the seat. At the upper end region of the backrest is connected to a pivotable head part, which is arranged lying in a seated position of the seat and standing in a rest position of the chair. In the sitting position, the backrest is steep, almost vertical, in the rest position, the backrest is inclined at an angle to the rear. A change in inclination of the backrest when moving the seat forward in the rest position causes a placement of the headboard. Pushing back the seat leads to the erection of the backrest and to turning the headboard backwards.

A disadvantage is considered in this seating, that the pivoting mechanism is visible at least from the back of the chair when the headboard. This disturbs the visual impression of such a chair when the seating is set up freely in the room.

On this basis, the invention has the object to propose a chair, in which the pivot mechanism is concealed both in the horizontal and in the upright state of the headboard from all sides of the chair.

This object is achieved by a chair with the features of claim 1. Further advantageous embodiments can be found in the dependent claims.

The seating furniture according to the invention, in which the headboard extends the backrest with erect headboard upwards, has a pivot mechanism which is concealed in the horizontal and in the standing position of the head part of the side panels, the back, the backrest and the headboard.

With such a variable seat furniture, the advantage is achieved that in the normal sitting position of the user, the backrest with headboard is not higher than a back part of a conventional non-adjustable seating, so that such seating are aesthetically combined with each other in a room. At the same time, the optical image of such a chair or one of group composed of such a seat is not adversely affected if, in one or more of the seats, the headboard is set up for a comfortable leaning position of the user.

In an advantageous embodiment of the invention, the head part on a projecting tray, which covers the pivoting mechanism from above in the standing position of the head part. The shelf is preferably arranged horizontally with erected headboard and can be used for storing objects. With a shortened backrest with a lying headboard, the shelf between the backrest and the backrest of the chair is hidden invisibly. It does not disturb the appearance of the seat when not in use.

In a variant of the seat according to the invention, the backrest is limited inclination changeable. The inclination of the backrest is made possible by suitable pivot fittings, by means of which the backrest is movably connected to the side parts, the back or a frame of the chair. The backrest of the chair can be adjusted by itself or together with a seat of the chair. When coupled with the seat backrest, a displacement of the seat causes a change in inclination of the backrest or a pivoting of the backrest a substantially horizontal displacement of the seat. The horizontal change in position of the seat part may additionally be superimposed on a vertical movement and / or inclination of the seat.

The adjustable in inclination backrest allows an enlarged body angle in the relaxed leaning position of the user, which is also more comfortable and fatigue-less headboard. For a high level of user comfort, the head part can also be coupled to the backrest in such a way that a change in inclination of the backrest between two end positions triggers or causes a reversal of the head part.

Advantageously, in an advantageous embodiment of the invention, the inclination of the backrest is coupled to the position of the head part. Preferably, by raising the head part from the lying position to the standing position by hand, a pivoting of the backrest from a steeper position (sitting position) into a more inclined position (leaning position) and / or a movement of the backrest forward, so that a seat depth is shortened. The first position of the backrest is the lying position, the second position of the backrest, the vertical position of the head part assigned. A pivoting of the head part in one or the other direction causes via the pivot mechanism a corresponding tilt adjustment and / or movement of the backrest. The pivoting mechanism used for this purpose can be designed in any way, provided that it ensures a corresponding positive entrainment of the backrest in a change in position of the headboard.

Preferably, the pivoting mechanism has a lock which is effective in the standing position of the head part. The latch, which is ideally self-locking, prevents the headboard from pivoting when the user's head is supported on the headboard. The locking can be done for example by means of spring force, which must be overcome for transferring the head part of the standing in the lying position by an applied hand force. The lock keeps the headboard securely in the standing position. A stable lying position of the head part can be achieved by an additional lock, which is similar to the locking for the vertical position of the head part is formed, and which acts in the lying position securing the pivot mechanism.

In one embodiment of the seat according to the invention, the side parts, the back and the backrest of the chair in a horizontal position of the head part on a uniform height. As sofa designed such seating are known as "Chesterfieldsofa".

The invention will be explained in more detail with reference to an embodiment shown in the drawing. Further features of the invention result from the following description of the embodiment of the invention in conjunction with the claims and the accompanying drawings. The individual features of the invention may be implemented on their own or in several different embodiments of the invention.

In the Figures 1-5 is an inventive seating in the form of a Chesterfieldsofas in a sitting position, in a leaning position and in intermediate positions when transferring the chair from the sitting position shown in the leaning position. They form the seating according to the invention in cross-sectional view schematically.

The illustrated seating furniture 1 according to the invention comprises a seat 2, a backrest 3 and a head part 4, which are arranged between side parts 5 along a back part 6 and are jointly supported by a frame 7. The head part 4 is arranged at an upper end of the backrest 3 and with the backrest 3 via a pivoting mechanism 8 relative to the seat 2, the side parts 5, the back part 6, the backrest 3 and the frame 7 pivotally connected, wherein the connecting pivoting mechanism 8 is fixed to the frame 7 of the chair 1. The head part 4 and the backrest 3 are articulated via the pivoting mechanism 8 to the frame 7, wherein the head part 4 of a in the FIG. 1 shown lying position in a in the FIG. 2 shown standing position, and vice versa, by means of the pivot pad 8 is pivotable. The standing headboard 4 extends the backrest 3 in the leaning position upwards.

The backrest 3, which has a padding like the seat 2 and the head part 4, is limited in the inclination with respect to the seat 2 changeable. The inclination of the backrest 3 is coupled to the position of the head part 4. In the in the FIG. 1 shown seat position of the chair 1, the backrest 3 is steeper when lying headboard 4 arranged as in the in the FIG. 2 The pivoting of the head part 4 of the lying in the standing position automatically causes a change in inclination of the backrest 4. At the same time, the backrest 3 moves a little forward shortens a seat depth of the seat 2 of the chair 1 and acts as a lumbar support ,

The pivoting mechanism 8 has for pivoting the backrest 3, a first four-bar linkage 9 and for pivoting the head part 4, a second four-bar linkage 10. The two four joints 9, 10 are coupled together. At the four-bar linkage 10, which raises the head part 4 during pivoting from the lying position to the standing position, a gas pressure spring 11 is provided as weight compensation for the head part 4. The gas spring 11 has a not visible in the drawing lock, which is effective in the standing position of the head part 4 and the four-bar 10 blocks there. By the coupling of the four joints 9, 10 while the four-bar link 9 is secured against pivoting, so that the backrest 3 is fixed in a stable position.

How out FIG. 1 seen, the side parts 5, the back part 6 and the backrest 3 of the chair 1 with a horizontal position of the head part 4 a uniform height relative to a bottom, not shown in the drawing. Like in the FIG. 1 can also be seen, the pivoting mechanism 8 in the sitting position with lying position of the head part 4 is not visible from the outside. The head part 4, the side parts 5, the back part 6 and the backrest 3 completely cover the pivoting mechanism 8.

Like in the FIG. 3 shown first position when erecting the head part 4 can be seen, a gap 12 between the back part 6 and the head part 4 is formed during pivoting of the head part 4 of the sitting position in the lean position of the chair 1, so that the pivot mechanism 8 is no longer completely covered. In order to close the gap 12 in the leaning position, that is, when the head part 4 is stationary, the head part 4 has a shelf 13 projecting vertically from the head part 4, which in the standing position of the head part 4, the swivel mechanism 8, as in the FIG. 2 shown, completely covered from above.

The FIG. 4 shows the head part 4 in a second intermediate position between the sitting and the leaning position of the chair 1, just before reaching the leaning position. The backrest 3 and the head part 4 together form a plane. To lock the four-link 10 and secure the four-link 9, it is like the FIG. 5 shows required to pivot the head part 4 slightly above the leaning position at the top forward. After pivoting back of the head part 4 in the leaning position, the four-bar linkage 10 is locked. The release of the lock for transferring the head part 4 in the horizontal position and the backrest 3 in the less inclined position takes place mutatis mutandis in the reverse direction. For this purpose, the head part 4 has to be pivoted forward again as for locking and can then be moved beyond the leaning position to the rear to the sitting position.
