Seating furniture chassis

Abstract

A seating furniture chassis including: a lever mechanism (2) for raising and lowering a seat face of a seating furniture item; a connecting mechanism (4) for connecting the lever mechanism (2) to the seat face; and a drive mechanism (3) for actuating the lever mechanism (2). A plane is defined by way of the connecting mechanism (4), in which plane the seat face lies in the mounted state. The seating furniture chassis (1) has a clearance below the plane, which clearance is free from the lever mechanism (2) and the drive mechanism (3). A footrest of the seating furniture item is pivotable into the clearance.

Claims

1. A seating furniture chassis (1), comprising: a lever mechanism (2) for raising and lowering a seat face of a seating furniture item configured so that the seat face is sittable on by a user, a connection mechanism (4) for connecting the lever mechanism (2) to the seat face, and a drive mechanism for actuating the lever mechanism (2), wherein a plane is defined by way of the connection mechanism (4), in which plane the seat face lies in a mounted state, wherein the seating furniture chassis (1) has a clearance below the plane, a footrest of the seating furniture item is pivotable into the clearance, wherein the footrest is positionable in the clearance approximately parallel to the seat face.

2. The seating furniture chassis (1) according to claim 1, wherein the clearance is arranged below the plane both in a raised and in a lowered state of the seat face.

3. The seating furniture chassis (1) according to claim 1, wherein the clearance is arranged in a front region of the seating furniture chassis (1).

4. The seating furniture chassis (1) according to claim 3, wherein the clearance is arranged in a front half of the seating furniture chassis (1).

5. The seating furniture chassis (1) according to claim 1, wherein the lever mechanism (2) is configured to incline and raise up the seat face during a raising operation and during a lowering operation.

6. The seating furniture chassis (1) according to claim 5, wherein the lever mechanism (2) is configured to incline the seat face during the raising operation in such a way that a front edge of the seat face is lower than a rear edge of the seat face.

7. The seating furniture chassis (1) according to claim 1, wherein the connecting mechanism (4) is configured for connecting the lever mechanism (2) to different seat faces.

8. A system, comprising a seating furniture chassis (1) according to claim 1 and the seat face, wherein the seat face is connected to the connecting mechanism (4).

9. The system according to claim 8, further comprising the footrest.

10. The seating furniture chassis (1) according to claim 1, wherein the clearance is free from the lever mechanism (2) and the drive mechanism (3).

DETAILED DESCRIPTION OF THE INVENTION

(8) The seating furniture chassis 1 comprises a lever mechanism 2, a drive means 3 and connecting means 4. The connecting means 4 are connected to the lever mechanism 2. A seat face (not shown in the figures) can be attached to the connecting means 4. The lever mechanism 2 is connected to the connecting means 4 in such a way that the lever mechanism 2 is configured to raise and lower the seat face. Moreover, the lever mechanism 2 is connected to the drive means 3 which can be, for example, a motor. The drive means 3 is configured to actuate the lever mechanism 2.

(9) Upon an actuation of the lever mechanism 2 by way of the drive means 3, the connecting means 4 are raised or lowered. Moreover, an inclination of the connecting means 4 is achieved. In the case of a raising operation, the rear ends of the connecting means 4 are raised up to a greater extent than the front ends. Here, the rear ends are shown on the right in the figures. The drive means 3 is arranged in the rear region of the seating furniture chassis. In the case of a lowering operation, the rear ends of the connecting means 4 are lowered to such an extent that they are oriented approximately parallel to the floor in the completely lowered state.

(10) The completely lowered state of the connecting means 4 is shown in FIGS. 1 and 2. The completely raised state is shown in FIGS. 5 and 6. FIGS. 3 and 4 show an intermediate position which is intended to clarify the raising and lowering mechanism.

(11) It is to be noted that the seating furniture chassis 1 has a clearance in the front region below the connecting means between two outer elements of the lever mechanism in every position, into which clearance a footrest of the seating furniture item can pivot. This has the advantage that the seating furniture chassis 1 can be used in combination with a footrest which can be pivoted in below the seat face and is arranged there approximately parallel to the seat face. A footrest of this type is also called a folded-under footrest.

(12) The clearance is free from the lever mechanism 2 which delimits the clearance towards the outside, and from the drive means 3 which is arranged in a rear region of the seating furniture chassis 1.

(13) Moreover, the connecting means 4 are configured in such a way that they can be connected to different seat faces. This increases the flexibility of the seating furniture chassis 1.
