The present disclosure relates to a seating furniture chassis.
Known seating furniture chassis have a base body and cables fastened thereto. The cables connect peripheral electrical devices, such as drive mechanisms and operating devices, to a central control unit. The cables are fastened to the seating furniture chassis and connected to the electrical devices and the control unit during manufacture.
By contrast, the underlying problem addressed by the present disclosure is to create a more flexible seating furniture chassis. In addition, a method for the assembly of such a seating furniture is to be created.
The seating furniture chassis comprises a base body and a plurality of electrical cables that are fastened to the base body. In the context of this specification, a base body is understood to mean, in particular, a construct that comprises a seat frame and one or more feet with which the seating furniture chassis is erectable on a floor surface. The seat frame can frame a seat. A user can sit on the upholstery after upholstering the seat surface.
Each of the cables has at a first end an individual connector, which is electrically connectable to a peripheral electrical device. Because each of the individual connectors is connectable to one of the peripheral electrical devices, the cables can be, in particular, connectable to a plurality of peripheral devices. In the context of this specification, an individual connector is understood to mean, in particular, a plug or a socket.
The seating furniture chassis also comprises a central connector. Each of the cables is electrically connected to the central connector at a second end. The second end is arranged opposite the first end. In particular, it is possible for the seating furniture chassis to comprise exactly one single central connector. In the context of this specification, the central connector is understood to mean, in particular, a plug or a socket.
Due to the connection of the cables to the central connector, for example, a control unit can be connected to the cables in a particularly simple manner by plugging the central connector into the control unit. An exchange or retrofitting of the control unit is therefore particularly simple.
It is possible, for example, for the cables to always be arranged on the seating furniture chassis, regardless of whether the seating furniture chassis is equipped with electrical devices or not. If, for example, a user acquires a piece of seating furniture with a seating furniture chassis that he or she has purchased without electrical devices, the user can simply acquire and retrofit the electrical devices and the control unit after the fact according to his or her requirements by connecting the cables to the subsequently purchased devices and the control unit. Due to the use of the central connector, the effort on the part of the user is particularly low. In addition, the cabling is already fastened to the seating furniture chassis, so that the risk of incorrect cabling is reduced. The cables can be arranged, for example, such that they respectively protrude into a receiving space for the peripheral electrical device to be connected to the respective cable. In this case, it is immediately clear to the user which cable is to be connected to the installed device.
It is also possible for one of the cables and/or one of the individual connectors and one of the peripheral electrical devices to have the same color, so that a user can simply discern which cable or individual connector is to be connected to which peripheral electrical device.
As a result of the cabling and the use of the central connector, the seating furniture chassis can also be expanded in a particularly simple manner with peripheral electrical devices. The exchangeability of peripheral electrical devices is also simplified.
According to a disclosed embodiment, the central connector can be connectable to a central electrical device. The central electrical device can be designed, for example, as a control unit.

According to a disclosed embodiment, the central electrical device can be designed in order to generate second control signals and emit them to the drive mechanism as a function of the first control signals. For example, the first control signal can comprise an indication that a user wishes to change the inclination of a backrest or wishes to extend or retract a footrest. In this case, the second control signal can comprise an indication of a rotational direction of the corresponding drive mechanism.
According to a disclosed embodiment, the central electrical device can be configured to automatically detect the peripheral electrical devices. In the context of this specification, this is understood to mean, in particular, that the detection occurs without user interaction. In addition, the central electrical device can be designed in order to detect a type and a functional scope of the peripheral electrical devices. In this manner, it is particularly simple for a user to exchange or reconnect peripheral electrical devices. Thus, for example, the functions of the seating furniture chassis can be expanded or changed.
The central electrical device can comprise a communication device for a wireless communication. The wireless communication can be, for example, Bluetooth and/or WLAN. For example, a remote diagnosis and/or a remote maintenance of the central electrical device and/or the peripheral electrical devices can occur via the communication device. The central electrical device can thus be designed in order to output an error message via the communication device.
It is also possible for the communication device to be configured to be wirelessly connected to a smartphone. Functions of the central electrical device and/or the peripheral electrical devices can thus be controlled via the smartphone.
According to a disclosed embodiment, the cables can be designed as a cable harness. This is understood to mean, in particular, that the cables are arranged in bundles. The cable harness can have been, for example, preassembled for the seating furniture chassis during manufacture so that the assembly is particularly simple.
According to a disclosed embodiment, the peripheral electrical devices can each comprise a data memory and a signal processor. The data memory can be configured, in particular, as a digital data memory. The signal processor can be referred to as a processor, for example. The signal processor can be configured to read out the data memory.
In this manner, the peripheral electrical devices can communicate with the central electrical device. This is particularly advantageous so that the central electrical device can automatically detect the peripheral electrical devices. A user can then simply reconnect one of the peripheral electrical devices, wherein the central electrical device can control this peripheral electrical device without further interaction on the part of the user.
The peripheral electrical devices can also comprise a plug and/or a socket, with which they can each be connected to one of the individual connectors.
It is also possible for the seating furniture chassis to comprise a multimedia unit, which can be controlled via the central electrical device. A user can then control the multimedia unit, for example, via an operating element of the central electrical device and/or via a smartphone. The multimedia unit can be designed, for example, to play back images, videos, and/or sounds.
In addition, the peripheral electrical devices can comprise a sensor. The sensor can be configured, for example, to detect whether a person is sitting on the seating furniture chassis. This can occur, for example, via the weight force exerted by the person.
In addition, the peripheral electrical devices can comprise further sensors configured to monitor vital signs of a person sitting on the seating furniture chassis. If, for example, no vital signs are detected, although it is simultaneously detected that a person is sitting on the seating furniture chassis, then an alarm can be triggered.
The peripheral electrical devices can comprise, for example, a footrest drive mechanism and a backrest drive mechanism. In this case, the central electrical device can comprise a manual switch and/or a control panel. The footrest drive mechanism can be configured to move a footrest of the seating furniture chassis.
