DETAILED DESCRIPTION

(15) A first fastener 100 is arranged on a base body of a seating furniture chassis, not shown in FIGS. 1A to 1D. A back part can be fastened to the first fastener 100. For this purpose, the back part has a latching element 101 and a positioning element 102. The positioning element 102 in turn comprises a bolt 103. The first fastener 100 comprises a positioning area 104, a first spring element 105, a latching area 106, and a first fastening element 107.

(16) The first spring element 105 is connected to the first fastening element 107 and exerts a first spring force on the first fastening element 107. The first fastening element 107 is pivotable about a first pivot axis.

(17) In FIGS. 1A to 1D, the fastening process of the back part to the first fastener 100 is shown in chronological order. At firstas shown in FIG. 1Athe back part and the first fastener 100 are separate from one another. Using the positioning element 102, a connection is then established between the first fastener 100 and the back part. The bolt 103 is inserted into the positioning area 104. For this purpose, it is advantageous for the outer shape of the bolt 103 to be adapted to the shape of the positioning area 104. In addition, the bolt 103 and the positioning area 104 can have the same color, so that assembly is simplified for a user, because the same color indicates to the user that these two components must be connected to one another. The bolt 103 thus defines a second pivot axis, about which the back part is pivotable. This state is shown in FIG. 1B.

(18) In order to simplify the insertion of the bolt 103 into the positioning area 104, the positioning element 102 has a slope over which the positioning element 102 can glide, so that the bolt 103 is inserted into the positioning area 104.

(19) The back part is then pivoted about the second pivot axis. In so doing, the latching element 101 comes into contact with the first fastening element 107 and pivots about the first pivot axis counter to the first spring force. Here, it is advantageous for the latching element 101 to have a slope on the side facing the first fastening element 107 during the fastening process, so that an insertion is simplified. This state is shown in FIG. 1C.

(20) When the pivoting movement of the back part about the second pivot axis is continued, the latching element 101 arrives in the latching area 106. For this purpose, it is advantageous for the outer shape of a section of the latching element 101 to be adapted to the shape of the latching area 106. In this position, the first fastening element 107 exerts a latching force on the latching element 101, the force being caused by the first spring element 105. In this manner, the latching element 101 is held securely in the latching area 106. This state is shown in FIG. 1D.

(21) FIG. 2 shows the first fastener 100, wherein the back part is fastened to the first fastener 100. This state therefore corresponds to the state shown in FIG. 1D. FIG. 2 further shows that the first fastener 100 comprises two first fastening elements 107. The back part comprises a plurality of positioning elements 102. The first fastener 100 comprises a corresponding number of positioning areas. FIG. 2 also shows two spring fasteners 200, to each of which one of the first spring elements 105 is fastened in order to exert the first spring force on the respective first fastening element 107.

(22) The seating furniture chassis shown in FIG. 3 comprises a base body 300 with a seat frame, the first fastener 100 arranged on the base body 300, and a back part 301 fastened to the first fastener 100. The back part 301 comprises the positioning element 102 and the latching element 101. The back part 301 is fastened to the first fastener 100 with the latching element 101 and the positioning element 102.

(23) The embodiment shown in FIG. 4 differs from the embodiment in FIG. 2 in particular in that the first fastening element 107 comprises a spring mechanism 400, which is guided in a guiding mechanism 401 and is latchable into a latching mechanism 402.

(24) The function of the embodiment from FIG. 4 can be understood using FIGS. 5A to 5E. When the latching element 101 is to be released from the first fastener 100, the first fastening element 107 is pivoted such that the latching element 101 is released. In this state, the latching element 101 no longer exerts any force on the first fastening element 107. During the pivoting of the fastening element 107, the spring mechanism 400 is guided in the guiding mechanism 401 and latches into the latching mechanism 402 such that the first fastening element 107 is no longer automatically moved back. This state is shown in FIG. 5A.

(25) The back part can now be removed. Subsequently, the spring mechanism 400 can be elastically deformed such that it is moved out of the latching mechanism 402 (FIG. 5B). It is pivoted back by the spring force of the first spring element 105 (FIG. 5C) and arrives at a stop. The spring mechanism 400 can then be deformed back again such that it arrives in the guiding mechanism 401. The first fastening element 107 is then pivoted back further so that it is again suitable for fastening of the latching element 101.

(26) The cables 600 shown in FIG. 6 are each connected at a first end to a single plug 601, which can be plugged into a socket. It would also be possible to connect the cables 600 to a socket, into which a plug can be inserted. The cables 600 are also connected at their second end to a central plug 602, which can be plugged into a socket. It would also be possible to connect the cables to a central socket, into which a plug can be inserted.

(27) Due to the use of the central plug 602, a central electrical device can be electrically connected to the cables in a particularly simple manner, so that the central electrical device can be connected after the fact, for example by a user. In addition, the use of the central plug 602 reduces the risk of incorrect contacting.

(28) FIG. 7 shows that the cables 600 are fastened to the base body 700 of the seating furniture chassis. Here, the plugs 601 are arranged such that they can be connected in a particularly simple manner to electrical peripheral devices, such as a motor or an operating device. Due to this arrangement, it is particularly simple for a user to correctly electrically connect the peripheral electrical device to the central electrical device.

(29) If, for example, a back part with a central electrical device is to be connected to the base body 700, this can be done simply by making contact with the central plug 602. This is particularly advantageous in combination with the particularly simple exchangeable back part shown in FIGS. 1 to 5. Retrofitting with the central electrical device is also particularly simple.

(30) In case of a retrofitting of the side parts of the seating furniture chassis, the plugs 601 can be used in a particularly simple manner for the electrical connection to peripheral electrical devices. This is particularly advantageous in combination with the exchangeability of the side parts described below.

(31) FIGS. 8A to 8D show only a section of the side part 800. This is the section with which the side part 800 is fastened to the second fastener 801. FIG. 8E shows an enlargement of the section labeled D in FIG. 8D.

(32) The second fastener 801 comprises a second fastening element 802, a guiding element 803, a second spring element 804, and a support element 805. The side part 800 has a support area 806, a receiving area 807, a glide surface 808, and a clamping mechanism 809. The second spring element 804 exerts a second spring force on the second fastening element 802, such that the second fastening element 802 is held in the first position shown in FIG. 8A.

(33) In order to fasten the side part 800 to the second fastener 801, the support area 806 is initially placed on the support element 805. In order to facilitate assembly for a user, the support element 805 and the support area 806 can be designed in the same color. It can thus be made clear to the user in a simple manner that these two components must be connected to one another. This state is shown in FIG. 8B. The side part 800 is then pivoted about a pivot axis, which is defined by the support element 805. During this pivoting movement, the glide surface 808 comes into contact with the second fastening element 802 and moves it counter to the second spring force. During this movement, the second fastening element 802 is guided in an elongated hole in the guide element 803. This state is shown in FIG. 8C.

(34) During the pivoting movement, a protrusion 810 of the side part 800, for example a bolt or a rivet, engages with a recess 809 on the second fastener 801. The projection 810 and the recess 809 form a positive-fit connection in a vertical direction. A vertical movement of the side part 800 relative to the second fastener 801 is thus limited or prevented.

(35) FIG. 8D shows how the side part 800 is fastened to the second fastener 801. The second fastening element 802 is again in the first position and is held there by the second spring force. In addition, the clamping mechanism 809 exerts a clamping force on the second fastening element 802 in this position, such that a particularly good fastening is achieved, and mechanical play of the second fastening element 802 in the first position is reduced.

(36) FIGS. 11 and 12 show that the seating furniture chassis has a seat frame 1100 on which the second fastener 801 is arranged. The side part 800 is thus fastened to the seat frame 1100 laterally.

(37) Referring now to FIG. 13, an example embodiment of a seating furniture chassis according to the present invention is depicted and will now be described.

(38) As shown in FIG. 13, the seating furniture chassis comprises a first side part 1, a second side part 2, a back part 3, and a seat frame 4. The first side part includes a first peripheral electrical device 5 and the second side part includes a second peripheral electrical device 6. As described herein, the first and second electrical devices may be designed as first and second operating devices, respectively, for different functions of the seating furniture chassis.

(39) The seating furniture chassis can also comprise a third peripheral electrical device 7 which can be arranged in a free space below the seat frame 4. The third peripheral electrical device can be, for example, a drive mechanism for adjusting the back part 3 (e.g., a backrest). The back part of the seating furniture chassis can include a central electrical device 8 which can be arranged below the backrest. The central electrical device may be arranged as a control unit.

(40) Again referring to FIG. 13, the seating furniture chassis further comprises a first cable 9, a second cable 10, a third cable 11, and a central connector 12. As shown, the first cable 9 can be arranged to protrude in the direction of the first side part 1, the second cable can be arranged to protrude in the direction of the second side part 2, the third cable 11 can be arranged to protrude in the direction of the free space below the seat frame 4, and the central connector 12 can be arranged such that it protrudes in the direction of the back part 3. The central connector 12 may be a plug or a socket.

(41) As further depicted, the seating furniture chassis comprises a plurality of individual connectors 13, 14, and 15. Each individual connector may be a plug or a socket. The first cable 9 is connectable to individual connector 13, the second cable 10 is connectable to individual connector 14, and the third cable 11 is connectable to the central connector 12. The cables each connect one of the individual connectors 13, 14, 15 to the central connector 12.
