Description

Technological background

Seating furniture is known in different versions. The nature of the seat and backrest of a chair is of great importance for the comfort of sitting. Depending on the area of application, seating or leaning surfaces may be made of different materials, such as wood, plastic, textile, metal or the like.

There are many design variations of seats and backrests. These can decisively shape the seating comfort. Different surface structures may e.g. stabilize the desired sitting position, fulfill a seat comfort function or have good cleaning properties.

Object of the present invention

The object of the present invention is to provide a sitting and / or reclining furniture with a novel seating and / or lying surface.

Solution of the task

The present object is achieved by the entire teaching of claim 1. Advantageous embodiments of the invention are claimed in the subclaims.

According to the invention, the seat surface and / or the backrest comprises or at least partially comprise a plurality of elongated elements which are freely rotatable about their longitudinal axis and arranged side by side. This results in the advantage that the user in sitting or lying position can make a laterally directed to the axis of rotation of the elements movement. The movement is used for easy seating position change and also causes a massage function. The seating comfort is thereby considerably improved. The invention also makes it possible to achieve specific massage effects by selective selection of the shape and / or surface formation of the elements.

The elongated elements are preferably arranged at least partially parallel to each other. This results in the advantage of a uniform over the sitting and / or lying surface movement of the user, laterally to the axis of rotation of the elements.

The seat surface and / or the backrest comprises or comprise a frame, on which the elements can be accommodated fixed on the face side. As a result, a stable support of the elements is achieved.

According to an advantageous embodiment, the base frame is attached to the underside of the frame of the seat. This results in the advantage that the seat can be pre-assembled separately with the elements and then connected to the base. For this, the seat can preferably be fixed to the underframe with a screw connection, e.g. be secured using a grub screw.

Preferably, there is a gap between the underframe and the frame to ensure a resistance-free rotation of the elements. The gap can be formed by means of spacers, in particular washers.

Alternatively, the base frame can form the frame. As a result, the base takes over the recording function of the frame. The elements are in this case housed fixed in the frame frontally. Due to a reduced number of components results in a structural advantage.

Preferably, a backrest support for fixing and stabilizing the backrest is provided, which is located at the respective rear side of the elements, whereby a discharge of the elements located within the frame takes place.

The backrest support may preferably be connected to the frame and / or the underframe, preferably in the form of a one-piece backrest support for the frame and underframe. As a result, the overall structure is additionally stiffened.

Preferably, the frame of the seat and / or the backrest may comprise a plurality of frame parts, which are connectable to each other. The multi-part frame construction results in advantages in the production. The rotatable elements may be inserted into the frame parts prior to joining the frame parts. Subsequently, the frame parts can be joined together.

Characterized in that the elements are at least partially cylindrical, a slight rolling process in sitting or lying position is possible. The elements may e.g. Be tubes or rods.

According to an expedient embodiment, the frame parts are designed as curved frame parts and / or as rectilinear frame parts. The curved frame parts preferably have a curvature of 90 °. As a result, the seating and / or reclining furniture can optionally be extended in a modular manner by further rectilinear frame parts. This results in the advantage that the length of the seat and / or reclining furniture can be made variable.

For the rotary connection between the respective element and the frame part, a pin is preferably provided, which engages in a bearing, preferably a sliding bearing. As a result, an easy rotation of the elements is ensured with a simple design.

According to a further advantageous embodiment of the sitting and / or lying furniture is provided as a rotatable element, a tube in which the bearing is already pre-assembled. The pin is located here on the frame and can be hammered into the frame, stamped, screwed, pressed or secured in a different way.

According to a further expedient embodiment of the sitting and / or lying furniture, the pin is an integral part of the frame. This results in the advantage that the pin can already be formed as part of the frame during the manufacturing process. An additional step of the assembly of the pin can thus be saved.

By virtue of the fact that the upper side of the elements and the upper side of the frame preferably form a common plane, it is achieved that the upper side of the seat surface and the surface of the backrest have no disturbing elevations which reduce the sitting comfort.
