Definitions

  • the invention relates to a chair with a backrest, a frame and a connecting device for connecting the backrest and frame, wherein in a state of use of the seat at least a first connection and at least a second connection between the backrest and the connecting means are provided, wherein the first connection through Lowering of the backrest relative to the connecting device is closed, wherein the backrest is pivotally supported by the first connection to the connecting device, wherein the second connection such corresponding stop surfaces on the backrest and the connecting device comprises that in the use position pivoting of the backrest is prevented to the rear ,
  • the backrest can be connected by inserting the same in a connecting device with the frame of a chair.
  • a connecting device In the connection device, two slots are provided for this purpose, in each of which a roller of the backrest can be inserted.
  • the backrest can be fitted in the manner described without the aid of tools, it requires a high degree of tact and experience to quickly and reliably add the backrest in the manner described. This is especially the case when the connection points between the backrest and the connecting device in the joined state are not readily visible.
  • the present invention is therefore based on the object, the aforementioned and previously described in more detail seating in such a way and further, that the mounting of the backrest can be made easier and more reliable.
  • the backrest is connected via at least two connections with the connecting device in order to hold the backrest stationary relative to the frame of the seat.
  • the first connection is essentially closed by a movement of the backrest from top to bottom. If necessary, the backrest is attached to the connecting device or plugged into this.
  • the first connection allows pivoting of the backrest relative to the frame of the chair.
  • the backrest is positioned relative to the connection device insofar as the second connection can be provided by pivoting the backrest, in particular the upper end thereof, to the rear.
  • the second connection between the backrest and the connecting device by the plant of two corresponding stop surfaces characterized, one of which is provided on the backrest and one on the connecting device.
  • the system of abutment surfaces prevents pivoting of the backrest to the rear in the position of use of the seat.
  • the second connection thus provides a stop which prevents tilting of the backrest to the rear, when the user leans his body weight in this direction against the backrest.
  • a pivoting of the backrest to the rear is in particular a pivoting of the upper end of the backrest understood to the rear.
  • this does not mean pivoting of a headrest or the like arranged at the upper end of the backrest, relative to the rest of the headrest, which otherwise retains its position.
  • the pivoting preferably represents a pivoting of the backrest in particular as such around the first connection.
  • the backrest can be mounted very easily, quickly and reliably. It only requires the lowering of the backrest relative to the connecting device until the first connection is closed and a subsequent pivoting of the backrest, preferably the upper end, to the rear. In particular, it is not necessary to loosen the first compound again after its initial provision in order to then make the second compound.
  • the backrest By closing the first connection, the backrest is in fact positioned opposite the connection device, that the second connection can be provided by a simple pivoting of the backrest.
  • a piece of furniture that includes a frame in which both at least one seat and at least one backrest are held.
  • the frame can be designed differently and stand on the ground. For example, it may be a profile frame structure. However, the frame can also be provided as needed by two side parts, which can be firmly connected to each other via a cross-beam.
  • the frame of the chair in particular forms a frame of the chair in which the seat and / or the backrest are held.
  • connection device is understood to mean a device which can enter at least one first connection and at least one second connection with the backrest. It may be, for example, a mounting plate of a fitting, in particular swivel fitting, the chair.
  • the connecting device may be mounted, for example in the form of a support plate, on a side part or a cross member between two side parts of the seat.
  • the connecting device can in principle be designed in one piece or in several parts, with a one-part design being preferred for the sake of simplicity in many cases.
  • the at least one first connection and the at least one second connection are in particular formed successively during the assembly of the backrest.
  • the backrest and the connecting device are provided in a state of use of the seat, ie, a state in which a user is on the seat and leaning his upper body to the back of the backrest.
  • a pivoting of the upper end of the backrest to the rear is prevented in particular by the system of the corresponding abutment surfaces of the backrest and connecting device to each other.
  • the backrest is preferably stabilized by the first connection.
  • first connection and the second connection in the sense of the invention may in each case comprise different partial connections which may be spatially substantially separated from one another.
  • first connection comprises a plurality of partial connections which ensure the positioning and pivoting of the backrest relative to the connection device in order to ensure that the abutment surfaces of the second connection essentially come into contact with one another by pivoting the backrest.
  • the second connection can be provided above or below the pivot axis of the first connection, in which case attention must be paid to the pivoting direction and to the alignment of the stop surfaces.
  • the arrangement below the pivot axis of the first connection should be preferred because then with sufficient distance between the first and the second connection good accessibility of the abutment surfaces and a good stability of the backrest in the chair can be achieved.
  • the chair In a first preferred embodiment of the chair it is a upholstered furniture and / or a chair with a padded backrest.
  • the connections between the backrest and the connecting device should not be visible to the user. This regularly has the consequence that the exact positioning of the backrest when connecting the backrest with the connecting device for the fitter is not recognizable. The mechanic must therefore work essentially on feeling. Since the mounting of the backrest to the connecting device according to the present invention can be particularly simple and reliable, the assembly can be done easily by feel.
  • the sofa can be designed both as a single-seater and as a multi-seater, wherein the acceleration of the assembly of the backrest in the manner described above comes especially in multi-seat sofas to bear.
  • the first connection may comprise a positive connection in a direction substantially downwards and / or in a substantially horizontal direction.
  • the first connection can be easily closed by plugging or plugging in the connection device.
  • the fitter is indicated by the positive connection down when the first connection is joined.
  • the positive connection in Horizontal direction the backrest in this direction securely hold the connecting device.
  • a positive connection in the horizontal direction for an alignment of the backrest along and / or across the seating provide, so that, for example, the second connection is safe by merely pivoting the backrest.
  • the horizontal positive connection of the first connection in at least one direction substantially parallel to the width of the backrest, in a forward direction and / or in a backward direction based on the seating. It is particularly preferred when the positive engagement acts in all these directions.
  • the second link may comprise a positive connection.
  • the positive connection is preferably a locking connection, since such a connection can be added simply by pivoting the backrest.
  • the fitter can be indicated by an audible latching of the backrest with the connecting device, that the connection is securely joined.
  • the second connection can have at least one guide surface.
  • the at least one guide surface can then when joining the slide second connection for positioning the backrest relative to the connecting device in the horizontal and / or vertical direction on the backrest or on the connecting device. It can thus be achieved that the second connection reliably finds itself and / or centers itself during the joining process.
  • the guide surfaces can be inclined both to the vertical and also to the horizontal or in both directions.
  • the latching connection of the second connection may have a latching element and a spring means. It lends itself to when the locking element can be deflected against the restoring force of the spring means to separate the locking connection of the second connection again. For example, a replacement of the backrest is easily possible.
  • the interlocking connection of the second connection can, if necessary, be formed by a bolt passing through the backrest and / or the connecting device and a securing preventing the bolt from being pulled out.
  • the backup can be a split pin.
  • Such a connection is not only simple and inexpensive to manufacture, but can, if necessary, also absorb high forces.
  • the provision of the first connection can be simplified constructively and in terms of handling, in that the first connection has an upwardly open receptacle, such as in FIG Shape of a groove, having on the connecting device.
  • the backrest preferably with a cross strut of the backrest, intervene.
  • the fitter receives a good feedback as to whether the first connection has been established as intended, even if he can not visually verify this because of the upholstery of the backrest.
  • the connecting device can have a guide surface in front of and / or behind the receptacle with respect to the seating furniture.
  • This guide surface is designed so that it can come into contact with the joining of the first connection with the backrest before the first connection is established.
  • the backrest can slide along the guide surface in the direction of the recording.
  • the backrest as a result of gravity, preferably automatically, engage in the receptacle when the backrest is positioned correctly for receiving. Making the first connection can be done quite easily, even if the backrest is padded so that the recording when joining the first connection is not recognizable.
  • the at least one guide surface may be inclined relative to the horizontal such that when the backrest slips against the guide surface, a direction toward receiving from a direction away from the receptacle may be differentiated. This can be achieved, for example, by the at least one guide surface being inclined downwards or upwards in the direction of the receptacle. So is with sufficient inclination the movement of the backrest in the one direction of the recording for the mechanic recognizable easier than moving the backrest in the other direction.
  • the first connection preferably forms a horizontal positive connection in at least one direction parallel to the width of the backrest.
  • the backrest can be aligned and positioned relative to the seating during assembly in this direction. This also simplifies the production of the second compound.
  • This alignment can be achieved in a structurally simple manner, for example by the fact that the connecting device engages adjacent to at least one frame element in a profile frame of the backrest.
  • first connections and / or two second connections are provided. It is particularly expedient if the two first connections and / or two second connections are provided on opposite sides of the seat, in particular assigned to opposite side parts of the seat.
  • FIG. 1 is schematically illustrated a chair 1 in the form of a padded chair.
  • the chair has a padded seat 2 and a padded backrest 3, which are provided in a base frame 4 of the chair 1 between two side walls 5. Shown is only one side wall 4. On the opposite side wall, which is formed analogously to the illustrated side wall 4, there are the same compounds, which are described in more detail below.
  • the backrest 3 is connected via a connecting device 6 with the seat 2 and the side part 5.
  • the backrest 3 can form a first connection 7 and a second connection 8 with the connection device 6.
  • first connection 7 is shown closed.
  • second connection 8 is not yet joined.
  • the connecting device 6 in the manner of a connecting plate educated.
  • the connecting device 6 has an upwardly open receptacle 9 to form the first connection 7.
  • This receptacle 9 is formed in the illustrated and insofar preferred seating 1 in the form of a downwardly tapered and closed groove.
  • the receptacle 9 is formed corresponding to a transverse strut 10 of the backrest 3, which can be inserted substantially accurately from above into the receptacle 9. The end position of the transverse strut 10 in the receptacle 9 is thereby automatically taken when the cross member 10 rests positively on the groove bottom of the receptacle 9.
  • the connecting device 6 can absorb the forces that press the backrest 3 when using the chair 1 to the rear.
  • the rear end of the connecting device 6 has a slightly inclined guide surface 11. Seen in the direction of the back of the chair 1, this guide surface 11 is slightly inclined inwards, away from the side wall 5.
  • a frame element 12 of the backrest 3 can slide along this guide surface 11 before the transverse strut 10 of the backrest 3 is received in the receptacle 9. Subsequently, the backrest 3 is aligned in a direction parallel to the width of the backrest 3 with respect to the seating 1, because on the other side another connecting means 6 engages analogously in a frame structure 13 of the backrest 3.
  • the frame structure 13 of the backrest 3 is thus positively positioned on the outer sides of the connecting means 6. In other words is the backrest 3 fixed against displacement to the left and right.
  • stop surfaces 14,15 are provided which belong to the second connection 8.
  • the stop surfaces 14,15 get into contact with each other when the backrest 3 is inserted into the receptacle 9 of the connecting device 6 and then pivoted backwards.
  • a latching connection 16 of the second connection 8 is closed in this way by a locking lug 17 of the backrest 3 engages behind a detent fitting 18.
  • the second connection 8 has an inclined guide surface 19, which effects a forced alignment of the latching lug 17, while it is passed through an opening 20 of the connection device 6 or is guided past the connection device 6. This is especially true in the Fig. 2 shown.
  • the connection of the backrest 3 with the connecting device 6 of the seat 1 will be described in detail with reference to FIGS Fig. 3A to 3D described in more detail.
  • the backrest 3 of the connecting device 6 is approximated from the back above, as shown in the Fig. 3A is shown.
  • the upholstery 21 of the backrest 3 is not recognizable for the fitter, where the receptacle 9 of the connecting device 6 is exactly, the fitter will initially in the illustrated and so far preferred seating 1 approximate the backrest 3 to the connecting device 6 until the Connecting device 6, starting with the guide surfaces in the frame structure 13 of the backrest 3 engages, as shown in the Fig. 3B is shown. This gives the fitter a haptic feedback.
  • the fitter now lowers the backrest 3, until the seat back 3 is seated with the transverse strut 10 on the rear guide surface 22 of the connecting device 6 in the seating unit 1 that is preferred and preferred. Now the fitter can slide the backrest along the guide surface 22 forward until the backrest 3 slips into the receptacle 9 without any further action on the part of the fitter.
  • the latching element 25 is spring-loaded.
  • the detent 17 can engage under the latching element 25 and deflect against the restoring force of the spring 26 upwards.
  • the latching element 25 passes as a result of the restoring force of the spring 26 in an undercut 27 on the backrest 3.
  • the abutment surfaces 14,15 of the backrest 3 and connecting device 6 abut each other to a to prevent further pivoting of the backrest 3 to the rear, as shown in the Fig. 3D is shown.
  • the latching element 25 can be raised against the restoring force of the spring 26, if necessary, to release the latching connection and pull the locking lug 17 out of the connecting device 6.
  • FIGs. 4A to 4D Alternative embodiments of the latching connection of the second connection 8 between the backrest 3 and the connecting device 6 are shown.
  • the same reference numerals are used for the same components.
  • the locking connection according to Fig. 4A engages the downwardly facing locking lug 17 via a pin-shaped locking element 25, which can be pressed down. This is done counter to the restoring force of a spring 26 so that the pin-shaped locking element 25 engages after passing the locking lug 17 upwards in a locking groove 28 of the backrest 3 and so accidentally loosening the second connection 8 prevented.
  • This locking connection can also be separated again by the pin-shaped locking element 25 is moved down as far as it releases the locking lug 17 of the backrest 3. It is understood that the assignment of locking element 25 and locking lug 17 to the backrest 3 and the connecting device 6 in the illustrated latching connections, if necessary, can also be reversed.
  • Fig. 4B is a positive non-latching connection of the second connection between the backrest 3 and the connecting device 6 is shown.
  • the backrest 3 has a pin 29 which engages through an opening 20 of the connecting device 6 therethrough.
  • the bolt 29 is secured in this position by a securing element 30 which engages positively in a groove of the bolt 29.
  • One of the abutment surfaces 14 of the second connection 8 is provided on an elastic element 31, for example in the form of a rubber disc. So it can be ensured that the second connection 8 has no significant game. Otherwise, the backrest 3 would not be held without clearance in the connecting device 6.
  • a similar connection is also shown with a bolt 29 and an elastic member 31.
  • a bolt 29 and an elastic member 31 is in the connection according to Figs. 4C and 4D
  • no separate fuse element provided.
  • the fuse element 32 is rather integrated in the pin 29 and held spring loaded therein. If the bolt 29 of the backrest 3 is pushed through the corresponding opening 20 on the connecting device 6, the Spring 33 is compressed and the securing element 32 is pressed into a recess of the bolt 29. When the bolt 29 has reached its final position, the opening 20 of the connecting device 6 releases the securing element 32, which slips out of the bolt 29 again by the restoring force of the spring 33. Therefore, the in Figs. 4C and 4D shown second connection can also be regarded as a latching connection.
