Definitions
- the invention relates to seating furniture with a chassis, a seat part and a swing-out footrest connected to the seat part via a kinematics module, the footrest comprising at least a first and a second foot part fitting which are coupled to one another in such a way that the second foot part fitting can be removed from the seated position of the piece of seating furniture, in which the first and second foot part fittings are pivoted underneath the seat part, can be pivoted into a reclining position of the seating furniture item, in which the second foot part fitting forms an extension of the seat part with the first foot part fitting, adjoining the seat part, with the second foot part fitting turning into a the end of the swiveled-out first foot part fitting that is remote from the seat part is swiveled into an approximately horizontal position.
- Another disadvantage is that the parts of the footrest are each relatively short.
- the invention is based on the object of further developing a piece of seating furniture of the generic type in such a way that the footrest in the swiveled-out position has both an almost continuous leg support due to the fact that there is only a small gap between the seat part and the footrest and also a significantly longer support surface compared to has the well-known seating furniture.
- the kinematics module arranged between the seat part and the footrest, in the form of articulated levers that are operatively connected to one another, enables a "flat" movement curve of the front edge of the footrest, which is opposite to a horizontal plane spanned by the front edge of the swiveled-in footrest during the entire pivoting of the footrest from the sitting to lying position rising.
- the kinematics module of the chair according to the invention is controlled in such a way that, when the footrest is in the pivoted-out position, an almost continuous leg rest is made possible due to the fact that there is only a small gap between the seat part and the footrest.
- FIG. 1 shows a piece of seating furniture according to the invention in the form of a two-seater sofa, one with the footrest pivoted out and one with the footrest pivoted in;
- FIG. 2 shows the seating furniture according to the invention from a side perspective with a partially pivoted footrest
- Fig. 3 shows the seating furniture according to the invention in a detailed partial view with the footrest pivoted out and
- FIG. 4 shows the seating furniture according to the invention in a detailed partial view with the footrest pivoted in.
- the piece of seating furniture 1 consists of a chassis 5, a seat part 3 and a swing-out footrest connected to the seat part 3 via a kinematic module 2 in the form of articulated levers that are operatively connected to one another.
- the footrest 6 is designed in two parts and comprises a first 6a and a second foot part fitting 6b, which are connected to one another in an articulated manner.
- the first foot part fitting 6a and the second foot part fitting 6b are coupled to one another in such a way that the second foot part fitting 6b from the sitting position of the chair 1, in which the first foot part fitting 6a and the second foot part fitting 6b are pivoted in underneath the seat part 3, can be pivoted into a reclining position of the seating furniture item 1, in which the second foot part fitting 6b forms with the first foot part fitting 6a an extension of the seat part 3 adjoining the seat part 3, with the second foot part fitting 6b turning into a position corresponding to the seat part 3 end facing away from the pivoted first foot part fitting 6a lengthening, approximately horizontal position is pivoted.
- the kinematics module 2 of the item of seating furniture 1 comprises a first 7 and a second 8 articulated lever, each articulated on the seat part 3, with the first articulated lever 7 being positioned closer to the rear edge of the item of seating furniture 1 than the second articulated lever 8.
- the end of the first articulated lever 7 facing away from the seat part 3 is articulated to a first end of a third articulated lever 9 .
- the third articulated lever 9 is articulated with its second end to the first foot part fitting 6a.
- the end of the second articulated lever 8 facing away from the seat part 3 is articulated to a middle region of the third articulated lever 9 .
- a fourth articulated lever 10 is articulated, on the one hand, to a middle region of the second articulated lever 8 and, on the other hand, to the first foot part fitting 6a.
- a control lever 11 is articulated at a central region of the fourth articulated lever 10 and at its free end at a first end of a coupling lever 12, the coupling lever 12 being articulated at its central region at the first foot part fitting 6a.
- the coupling lever 12 is articulated with its second end to a first end of a connecting lever 13, which is connected with its second end in an articulated manner to the second foot part fitting 6b.
- the pivot point of the control lever 11 on the fourth articulated lever 10 is arranged in such a way that the distance between this pivot point and the pivot point of the coupling lever 12 on the first foot part fitting 6a is shortened and extended in a second phase of the pivoting of the chair 1 from the sitting to the lying position.
- the four articulated levers 7, 8, 9, 10 of the kinematics module 2 are controlled in such a way that when the footrest 6 is in the pivoted-out position, there is only a small gap between the seat part 3 and the footrest 6, which enables an almost continuous leg rest.
