- the front end and the rear end can be arranged lower than the central area.
- the front end is understood to mean in particular an end which is closer to the footrest in the unfolded state than the rear end.
- the rear end can in particular be arranged closer to fastening means for a backrest than the front end. The deeper arrangement is used in the context of this description
- This shape of the guide rail results in a particularly pleasant and easy for a user to trigger unfolding movement of the footrest.
- Guide element can be arranged at the rear end of the first guide rail in the unfolded state of the footrest.
- Flebel mechanism include a flail rotatable on the
- the Flebel can be in
- the wing extends the folded state of the footrest forwards and downwards.
- the wing it is possible for the wing to be arranged directly on the seat frame.
- the “down” direction is in particular to be considered down when the seating furniture chassis is used as intended
- the “front” direction is to be understood in particular as the direction in which a user looks when the seating furniture chassis is used as intended when he is sitting on the seat frame.
- This direction of the lever is advantageous so that a user can trigger the unfolding movement of the footrest particularly easily by exerting a rearward force on the seat surface frame. He can do this, for example, by contacting Supports armrests.
- the direction of the lever in combination with the shape of the first guide rail then causes the
- the lever can be rotatably connected to an element of the footrest.
- the lever In the folded-in state of the footrest, the lever can enclose an acute angle or a right angle with the element.
- the lever In the unfolded state of the footrest, the lever can form an obtuse angle with the element.
- Guide rail can be arranged laterally next to the seat frame. In the context of this description, this is understood in particular to mean that the first guide rail is arranged next to a lateral end of the seat surface frame, the lateral end extending from a rear to a front end.
- the seating furniture chassis can comprise a stand device.
- the stand device can be designed to stand stationary on a flat surface and to support the seat frame.
- the first guide rail can be fixedly connected to the stand device.
- Guide element protrude through the first guide rail.
- the seating furniture chassis can have a second guide rail and a second guide element include.
- the second guide rail When the footrest is transferred from the unfolded to the folded state and vice versa, the second
- Guide element are guided in the second guide rail. It is particularly possible that the second guide element
- the second guide rail can have the same shape as the first guide rail.
- Guide rail and the first guide element can be arranged laterally next to a first end of the seat surface frame.
- the second guide rail and the second guide element can laterally next to a second end of the seat surface frame
- the first end can be arranged opposite the second end.
- the seating furniture chassis can comprise a third and a fourth guide element and a third and a fourth guide rail.
- the third guide element and the third guide rail can be arranged laterally next to the first end of the seat surface frame.
- the fourth guide element and the fourth guide rail can be arranged laterally next to the second end of the seat surface frame.
- Guide element are guided in the third guide rail and the fourth guide element in the fourth guide rail.
- the third and fourth guide elements and the third and fourth guide rails can be arranged closer to a rear end region of the seat surface frame than the first
- the third and fourth guide rails can have a curved shape.
- the third and fourth guide rails can each have a front end, a rear end and a central region arranged therebetween.
- the rear end can be arranged lower than the central region and the front end. This shape triggers a lowering of the rear
- Guide element can be arranged at the rear end of the third guide rail in the unfolded state of the footrest.
- the fourth guide element can in the unfolded state
- Footrest can be arranged at the rear end of the fourth guide rail.
- the third guide element can be arranged at the front end of the third guide rail in the folded-in state of the footrest.
- the fourth guide element can be arranged at the front end of the fourth guide rail in the folded-in state of the footrest.
- Guide element when guided in the third guide rail and the fourth guide element when guided in the fourth guide rail can only be guided horizontally and / or downwards during the transfer of the footrest from the folded to the unfolded state.
- the downward guide can in particular include a movement that includes both a horizontal and a vertical component.
- the footrest can comprise an extension mechanism which is designed to the
- FIG. 1 shows two schematic views of a seating furniture chassis according to an embodiment of the invention with a footrest in a folded-in state
- Fig. 2 shows two schematic views of the seating furniture chassis
- Fig. 3 shows two schematic views of the seating furniture chassis
- the seating furniture chassis comprises a seat frame 100, a stand device 101, a first guide element 102, a first guide rail 103, a second guide element 107, a second guide rail 108, a third guide element 104, a third guide rail 105, a fourth guide element 109, a fourth guide rail 110 and a footrest 200.
- the guide elements 102, 104, 107 and 109 are fixedly connected to the seat frame 100.
- the guide rails 103, 108, 105 and 110 are fixedly connected to the stand device 101.
- the seat frame 100 is also connected to the footrest 200 via a bracket 106 and an element 111.
- Stand device 101 is used for the stable stand of
- the seat frame 100 is displaceable relative to the stand device 101, wherein during a displacement of the
- Footrest 200 translationally by a user
- the force can from
- the first guide rail 103 and the second guide rail 108 have a curved shape.
- the front end, at which the respective guide element 102 or 107 is located when the footrest is folded in, is arranged lower than a central region of the guide rail 103 or 108.
- the guide elements 102 and 107 are arranged at the rear end when the footrest 200 is in the unfolded state.
- the seat bottom frame 100 becomes a
- Transfer of the footrest 200 from the folded-in state to the unfolded state is initially pivoted upwards at the end facing the footrest. This movement has in combination with the extension direction of the lever 106 means that the
- Folding out movement of the footrest 200 can be triggered by the user moving the seat frame 100 backwards.
- an upper end of the element 111 forms an acute angle with the lever 106, while a lower end of the element 111 forms a right angle with the lever 106.
- the angle between the lever 106 and the element 111 increases during the unfolding process of the footrest 200, so that in the unfolded state the footrest 200 is arranged in a position that is comfortable for a user.
- the footrest is arranged close to the seat frame 100 in a particularly space-saving manner.
- the third guide element 104 and the fourth guide element 109 are arranged at a rear end of the seat surface frame 00 so that their guidance through the third guide rail 105 and the fourth guide rail 110 during the unfolding process of the footrest 200 prevents the rear end of the
