Definitions

  • the invention relates to seating with a frame, a backrest, a seat cushion and a legrest, the leg rest over a scissor grid with the Seat cushion is hingedly connected and the leg rest in the non-use situation essentially below that Seat cushion folded and in the position of use in front the seat cushion is unfolded so that the seat is covered the leg rest is extended.
  • a chair has become known from DE 197 00 617 A1, in which a two-part leg support by means of a Parallelogram construction can be folded out. Thereby the seat is extended so that the legs over find an edition over their entire length. However between the seat cushion and the two leg rests Transverse slots that may are undesirable.
  • the invention is therefore based on the object To provide seating of the type mentioned at the outset, which has an even more appealing design.
  • the object is achieved with a seating of initially mentioned type solved in that the seat cushion and the leg rest has continuous padding.
  • the leg rest in the seating furniture according to the invention their rest position below the seat cushion in their working position unfolded, the leg rest the seat cushion is extended so that the leg comfortably over it can lie on its entire length, then between the seat cushion and the leg rest Cross slot, because the upholstery from the seat up to Leg rest is carried out continuously.
  • the seat cushion extends almost to the end of the leg rest.
  • the Upholstery material can be a fabric, leather, a Plastic or a mixture thereof. Besides, can the padding is fully lined or padded.
  • the padding is provided in the joint area between the seat cushion and leg rest is elastic. In this way a default of Padding when the leg rest is folded in and / or out avoided.
  • the geometry of the scissor lattice designed so that the upholstery when unfolded Leg rest is tightened. As a result, the seating furniture has not only when it is folded but also when it is unfolded Legrest on an attractive design, with unfolded leg rest the transition from the seat cushion to the Leg rest is almost not recognizable.
  • the leg rest according to the invention pivoted at the same time when unfolding and extended.
  • the tightening of the Upholstery enables, the travel distance is dimensioned in this way is that the upholstery is just tightened, however not stretched.
  • the geometry of the scissor grid is like this sized that of the upholstery between the seat cushion and the extended leg rest to be bridged Stretch the arch section of the upholstery from the seat cushion corresponds to the leg rest with the leg rest folded.
  • the Unfold the legrest the seat cushion is raised.
  • leg supports can also be used whose length is greater than the distance from the front edge of the Seat cushion from the floor. Usually such would Legrests when unfolding with the seat cushion and the Collide ground. However, when unfolding the Legrest raised the seat cushion, then this can Leg pads can also be used.
  • the arm is preferably over a steering lever coupled to the frame so that the arm and the steering lever form a toggle construction.
  • this toggle lever in particular by operating the Steering lever, the front area of the seat cushion raised, so that the leg rest can be easily folded out.
  • an embodiment provides that the arm or the Steering lever is coupled to a drive.
  • This drive not only serves to lift the seat cushion, but also the scissor grille is also adjusted with the drive, i.e. the leg rest unfolded or folded.
  • a gas pressure spring or a drive motor for the drive used gas springs are simple and constructed are used universally in the furniture sector, they are but also inexpensive and durable. Has a drive motor the advantage that without external force Scissor lattice can be moved in both directions.
  • the arm and the steering lever at folded leg rest a self-locking position in which they are held by the drive.
  • the leg rest goes through the toggle construction, which is formed by the arm and steering lever, one Neutral position, in which the drive neither the knee lever can move to the other side.
  • the rest position the folded leg rest is taken when the toggle lever beyond this neutral position Has taken position in which the drive the knee lever drives to the other side, but in which he is blocked by a stop. That way the leg rest is kept stable in this rest position.
  • An independent invention provides that Seat cushion together with the backrest and the leg rest swiveling via a swivel bearing with the frame connected is.
  • the seat cushion can be used with this swivel bearing between two or more positions, i.e. Inclination of the seat cushion and backrest unit, be pivoted.
  • the swivel bearing points according to the invention on a backdrop over which the pivot positions To be defined.
  • the frame of the seating is with provided a role that moves within the backdrop.
  • the backdrop is for the role with defined rest positions provided in which the role by means of a this locking pawl is held. To this way, the frame is on the one hand in the end positions and possibly also kept stable in intermediate positions.
  • the Seat cushion 16 is in the front area 26 of the scissor grille 22, which in turn on a support frame 30th rests, and swiveling in the rear area from a swivel bearing 32 worn.
  • the backrest is also over a Swivel bearing 34 swivels with the back of the seat cushion 16 connected, the pivot position of the backrest 18 via the gas pressure spring 24, which in turn has a Bearing 36 attached to the underside of the seat cushion 16 is continuously adjustable.
  • the Scissor lattice 22 provides a further gas pressure spring 38 which on the one hand on the support frame 30, on the other hand on the scissor lattice 22 attacks.
  • the seat cushion 16 and the legrest 28 are on hers Upper side connected by padding 40, which are completely over the seat cushion 16 and the Leg rest 28 extends. At least in the joint area 42, the padding 40 is elastic, so that the Padding 40 of the movement of the leg rest 28 without problems can follow.
  • the scissor grid 22 can be more clearly in the position of the Figure 3 are described, in which it is partially is unfolded.
  • the scissor grid 22 is made of one Scissors cross with two scissor arms 44 and 46 and two Lattice arms 48 and 50 constructed.
  • the free ends of the Scissor arm 44 and the lattice arm 48 are on the underside of the seat pad 16 and the free ends of the scissor arm 46 and the lattice arm 50 are at the bottom of the leg rest 28 pivotally mounted in bearings 52 to 58.
  • the arms are 44 to 50 via pivot bearings 60 to 64 coupled.
  • the grating arm 48 engages over a pivot bearing 68 a steering lever 66, the free end of a bearing 70th of the support frame 30 is pivotally attached.
  • the steering lever 66 is via a bearing 72 with the gas pressure spring 38 connected, which in turn on a pivot bearing 74 on Support frame 30 supports.
  • the leg rest 28 is in the folded position below the seat cushion 26 and the Dimensions of the scissor lattice 22 together with the steering lever 66 are chosen so that in the folded position of the Scissor lattice 22, the line of action of the gas pressure spring 38 (Longitudinal axis of the gas pressure spring 38) below the bearing 70 lies, so that a force is exerted on the steering lever 66 who is trying to do this against the direction of the To pivot clockwise around bearing 70. Therefor can the free end of the gas pressure spring 38 either directly on Steering lever 66 or (as shown) on a projection be attached to this.
