Abstract

The object of the present invention is to provide a synchronous mechanism for a piece of seating and/or reclining furniture, with which an individual adjustment of the positions is made possible for the user, and there is no disturbing mechanism in the seat and back area. This can consist of at least one adjustment unit and can be mounted individually from one another so that there is a free space between the units. Furthermore, the object of the present invention is to be inexpensive to install and particularly easy to operate by the user in order to provide multifunctional use of a piece of seating and/or reclining furniture provided with the mechanism and/or locking means.

Description

The present invention is a synchronous mechanism for a seating and/or reclining furniture and its use. This can control movements, for example in the seat, back or headrest, synchronously without requiring a fixed connection such as a synchronous shaft.

background

In practice, we know of seating and/or reclining furniture whose synchronously guided adjustment mechanisms move electrically or motor-driven from the furniture in order to generate, for example, a greater seat depth or back height. In most cases, the synchronous mechanism is screwed in in such a way that it is noticeable in many pieces of furniture. This often leads to compromises in terms of appearance, condition and seat-back ergonomics.

Task

Therefore, the object of the present invention is to provide a synchronous mechanism for a piece of seating and/or reclining furniture, with which an individual adjustment of the positions is made possible for the user, and no disturbing mechanism is located in the seat and back area. Furthermore, the object of the present invention is to be inexpensive to install and particularly easy to operate by the user in order to provide multifunctional use of a piece of seating and/or reclining furniture provided with the mechanism and/or locking means.

The invention relates to a synchronous mechanism for a seating/reclining furniture. The invention also relates to a corresponding seating/reclining furniture.

Synchronous mechanisms have been proposed in different designs for different seating/reclining furniture. A synchronous mechanism can adjust various parts, synchronously, from an initial position to an extended position, and back again, continuously. This can be done manually or by motor.

It is considered disadvantageous that these designs require a space which largely excludes their use in seating/reclining furniture with very little space available, e.g. furniture with seat/back parts of a small seat/back thickness or curved elements.

In the course of improving the comfort of seating/reclining furniture in an expanded area of use, there is therefore a need for improvements for reduced installation conditions.

The invention defined in claim 1 is based on the object of creating an improved synchronous mechanism.

Another task is to create a seating/reclining furniture with improved comfort.

This object is achieved with the features listed in patent claim 1.

Advantageous further training is listed in the subclaims.

A synchronous mechanism according to the invention for a piece of seating/reclining furniture comprises at least two adjustment units (2) and a drive unit (1) which can be adjusted from an initial position to an extended position and back using a cable pull (3). The synchronous mechanism also has at least two adjustment units (2) in which a movement unit (10) is slidably guided. The adjustment unit (2) is connected to the movement unit (10), this holding point (5) clamps the cable pull (3). The cable pull (3) is connected to the holding point (5) on the adjustment unit (2).

This offers the advantage of a compact design and enables the use in seating/reclining furniture with reduced installation space to achieve greater comfort.

A seating/reclining furniture item according to the invention has at least two adjustment units (2) which are connected via at least one cable pull (3). This assembly has at least one drive unit (1) which is connected to the cable pull or the movement unit (10). The synchronous mechanism can be used for example for single-seat, two-seat and multi-seat seating/reclining furniture, which is advantageous.

A particular advantage is achieved by a low height and depth, as well as the universal width adjustment since the synchronous mechanism can be freely positioned.

In one embodiment, it is particularly preferred that the synchronous mechanism has an electric motor drive unit. This offers the advantage of particularly simple operation, especially for people with disabilities.

For this purpose, it is provided in one embodiment that at least two adjustment units (2), on which at least one guide device (8) is provided, in which a movement unit (10) is slidably guided. With the movement unit (10), the Clamping point (5) firmly connected, the clamping point (5) clamps the cable (3) so that it is firmly connected to the movement unit (10). The cable (3) is clamped to the holding points (6) and thus moves the movement unit (10).

In a further embodiment, the synchronous mechanism can consist of two or more adjustment units (2). This results in an advantageously low installation height or depth.

A further particularly advantageous embodiment provides that the adjustment units (2) can be connected by one or more cables (3).

It is advantageous if the drive unit (1) can be positioned separately from the adjustment unit (2).

A further particularly advantageous embodiment provides that the drive unit (1) can be firmly connected to the adjustment unit (2).

A particular advantage is that the drive unit (1), such as a motor, can be designed with a gas pressure spring, with a clamp fitting or with a locking or reversible mechanism.

Another special advantage of the drive unit (1) is its structure. The drive unit consists of a base plate to which an adjustment element such as a motor is attached. The base plate has two drive unit holding points (7) on the side through which the cable pull (3) runs. The drive has a carriage (9) that moves linearly to the cable pull (3). The cable pull (3) is firmly connected to the carriage (9) at the drive unit clamping point (7).

This means that the drive unit (1) is connected to the adjustment units (2) via the cable (3) and thus the movement of the drive unit (1) is transferred via the adjustment units (2) to the movement units (10). This allows a synchronous movement to take place in all movement units.

The invention is further described in connection with the figures using an exemplary embodiment.

The synchronous mechanism is intended for a seating/reclining furniture (not shown but easily imaginable) and is attached to it, e.g. in the back with the adjustment units (2). A person sitting in the seating/reclining furniture can therefore vary the height of the back.

The synchronous mechanism can be adjusted from a retracted position through an intermediate position to an extended position and back. The retracted position shows 1 ; 2 ; 3 ; 4 ; 10 ; 11 the intermediate position is not shown, and in the 5 ; 6 ; 7 ; 8 ; 9 ; 12 the extended position of the synchronous mechanism is shown.

The adjustment of the synchronous mechanism can be carried out with an electric motor drive unit (1).

The synchronous mechanism can be adjusted using a gas pressure spring.

The synchronous mechanism can be adjusted using a locking joint.

The synchronous mechanism can be adjusted using a clamping joint.

The adjustment of the synchronous mechanism can be carried out with a combination of the listed components and can also be designed to be reversible.

The synchronous mechanism can consist of two or more adjustment units (2).

The synchronous mechanism can consist of one or more cables (3).

The synchronous mechanism consists of at least two drive units which are equal to the adjustment unit (2) (for example linear drives). This shows 13

The fixed connections between the components can be rivets, screws, adhesives, or/and welded joints or similar.

The material for the frame components and the support unit is metal. Combinations with plastics and wood are also possible.

The invention is not limited by the embodiment described, but can be modified within the scope of the claims.
