Definitions
- the invention relates to a piece of seating furniture with a chassis, a seat part, a back part and a swing-out footrest connected to the seat part and/or to the chassis via an adjusting mechanism, the seating furniture item being able to be swiveled between a sitting and a lying position, the footrest in the sitting position is pivoted essentially under the seat part and is pivoted out in the reclining position in front of the seat part in such a way that the seat part is extended by the footrest.
- a disadvantage of the known seating is that the lower edge of the pivoted footboard must have a distance of more than 100 mm to the contact level of the seating furniture so that the extension board during the Pivoting of the seating furniture from the sitting to the lying position does not touch the floor.
- the footboard and the extension board are connected to one another in an articulated manner in such a way that the distance between the facing edges of the footboard and the extension board decreases during the pivoting of the chair from the sitting to the lying position.
- the invention is based on the object of further developing a piece of seating furniture of the generic type in such a way that even with a distance of preferably only 30 mm between the lower edge of the swiveled-in footboard and the contact level of the seating furniture item, an extension board can be made available which does not touch the floor during the pivoting of the seating furniture from the sitting to the lying position.
- the distance between the mutually facing edges of the footboard and the extension board should increase during the pivoting of the chair from the sitting to the lying position.
- a two-part footrest arrangement is proposed according to the invention, with a footboard attached to a foot part fitting of the footrest and an extension board attached to an extension part fitting, the foot part fitting and the extension part fitting being coupled to one another in such a way that the extension board can be removed from the sitting position in which the foot board is forms a front panel and the extension board is pivoted underneath the seat part, can be pivoted into the reclining position, in which the extension board with the footboard forms an extension of the seat part adjoining the seat part, the extension board extending into an end of the pivoted-out footboard that faces away from the seat part, approximately horizontal position is pivoted.
- An adjusting gear arranged between the seat part and the footrest in particular in the form of articulated levers that are operatively connected to one another, enables a "flat" movement curve of the upper edge of the footrest, which is opposite to a horizontal plane spanned by the upper edge of the swiveled-in footrest during the entire pivoting of the footrest from from the sitting to the lying position rises.
- two extension levers connected to the foot part fitting and two extension levers connected to the extension part fitting are coupled to one another and to the adjusting gear in such a way that the extension board, even with a distance of only 30 mm between the lower edge of the swiveled foot board and the contact plane of the seating furniture, during the swiveling of the footrest does not touch the floor from the sitting to the lying position.
- the movement curve of the extension board relative to the footboard is controlled by means of the articulated levers in such a way that the distance between the edges of the footboard and extension board facing one another increases during the pivoting of the footrest from the sitting to the lying position, as a result of which an overfoot and extension board extending, continuous padding is tightened.
- a one-piece upholstered footrest can be realized, while in the known piece of seating furniture there are two separately upholstered footboards or extension boards.
- FIG. 1 shows a piece of furniture according to the invention in the seating position of the piece of furniture
- FIG. 2 shows the seating furniture according to the invention in the sitting position of the seating furniture in a detailed partial view
- 3 shows the seating furniture according to the invention from a side perspective with a partially pivoted footrest
- FIG. 4 shows the seating furniture according to the invention in the reclining position of the seating furniture.
- the seating furniture item 1 consists of a chassis 5, a seat part 3, a back part 4 and a swing-out footrest connected to the seat part 3 via an adjustment mechanism 2 in the form of articulated levers that are operatively connected to one another, with the seating furniture item 1 between a position shown in Fig 1 and a lying position shown in FIG.
- the footrest 6 is designed in two parts and comprises a footboard 6b fastened to a foot part fitting 6a and an extension board 6d fastened to an extension part fitting 6c.
- the foot part fitting 6a and the extension part fitting 6c are coupled to one another in such a way that the extension board 6d can be pivoted from the sitting position of the chair 1, in which the foot board 6b preferably forms a front panel and the extension board 6d is pivoted underneath the seat part 3, into the lying position of the chair 1 in which the extension board 6d with the footboard 6b forms an extension of the seat part 3 adjoining the seat part 3, the extension board 6d being pivoted into an approximately horizontal position extending the end of the swiveled-out footboard 6b facing away from the seat part 3.
- the adjustment mechanism 2 of the seating furniture item 1 comprises a first 11 and a second 12 articulated lever, each articulated on the seat part 3 , which are articulated with their ends facing away from the seat part 3 in each case on a coupling lever 16 .
- a third articulated lever 13 and a fourth articulated lever 14 are each linked to the coupling lever 16 .
- a control lever 15 is articulated, on the one hand, to the first 11 or the second articulated lever 12 and, on the other hand, to the third 13 or the fourth articulated lever 14 .
- the third articulated lever 13 and the fourth articulated lever 14 are each articulated with their ends facing away from the coupling lever 16 to a first end lever 17, facing away from the seat part 3, of the adjusting mechanism 2, which is also articulated to the foot part fitting 6a.
- a second end lever 18, facing away from the seat part 3, of the adjustment mechanism 2 is articulated on the one hand in a central region of one of the third 13 and fourth articulated lever 14 and on the other hand on the foot part fitting 6a.
- a middle area of the articulated lever does not mean the exact geometric center, but rather the entire area of an articulated lever lying between the two end articulation points.
- the first 11 and the second articulated lever 12 are pivoted in such a way that the coupling lever 16 is pushed forward relative to the seat part 3, with the third 13 and the fourth articulated lever 14 being simultaneously moved relative to the Coupling lever 16 are pivoted and the foot part fitting 6a is pushed forward relative to the coupling lever 16.
- the coupling lever 16 is lowered relative to the seat part 3 during approximately the first half of the pivoting phase of the footrest 6 from the sitting to the lying position, with the foot part fitting 6a being raised relative to the coupling lever 16 at the same time (FIG. 3).
- This ensures that the upper edge 20 of the footrest 6b follows a "flat" movement curve, which rises in relation to a horizontal plane spanned by the upper edge 20 of the pivoted-in footrest 6b during the entire pivoting phase of the footrest 6 from the sitting to the lying position.
- a first extension lever 7 and a second extension lever 8 are articulated at a distance from one another on the foot part fitting 6a, with the first end lever 17 of the adjusting gear 2 being extended beyond the area of its articulation point on the foot part fitting 6a and at its free end on a first end of a connecting lever 19, the second end of which is pivotally connected to one of the first extension lever 7 and second extension lever 8.
- the pivot point of the first extension lever 7 on the foot part fitting 6a is positioned closer to the seat part 3 when the seating furniture 1 is in the sitting position than the pivot point of the second extension lever 8 on the foot part fitting, with the end of the first extension lever 7 facing away from the pivot point on the foot part fitting 6a is articulated at a first end of a third extension lever 9, the second end of which is articulated to the extension piece fitting 6c.
