Seating furniture
The invention relates to seating furniture comprising two frames arranged at a distance to each other on a support, between which frames a seat part and a backrest part can be mounted, and the frames have one upper frame part and a lower frame part each which mechanically immobilize the seat part and the backrest part a the sides thereof. The upper frame part and the lower frame part are clamping elements that can be braced with each other. At least one clamping element has a laterally extending recess on each edge which recess forms a frame groove in which a respective engaging element provided on the edges of the seat part and of the backrest part can be mounted by way of a frictional connection to the upper frame part and the lower frame part. The recess has an undercut portion which forms a stop for holding the clamped engaging element by a form fit.
1. Seating furniture, comprising at least two frames which are arranged at a distance horizontally to each other on a support and between which the at least two frames a seat part and a back part are suspended, and the at least two frames each have a top frame part and a bottom frame part which mechanically fix the seat part and the back part at the periphery, wherein the top frame part and the bottom frame part comprise releasably braceable clamping bodies, at least one of the releasably braceable clamping bodies has a hollow that extends to an open side of a peripheral edge of the top frame part and the bottom frame part and forms a frame joint in which an engagement member that is provided at a respective peripheral edge of the seat part and of the back part is fastened by frictional connection to the top frame part and bottom frame part, and the hollow has an undercut which forms a stop for securing the engagement member in a form fitting manner.
2. The seating furniture as claimed in claim 1 , wherein the top frame part is formed in one piece in order to fasten the seat part and back part.
3. The seating furniture as claimed in claim 2 , wherein the top frame part is formed in an L-shaped manner, having a seat-part clamping section, a back-part clamping section and an arcuate transition section arranged in between.
4. The seating furniture as claimed in claim 3 , wherein the arcuate transition section has an internal reinforcement rib.
5. The seating furniture as claimed in claim 3 , wherein the top frame part is connected to the bottom frame part in a flush manner at the periphery in the region of the arcuate transition section.
6. The seating furniture as claimed in claim 1 , wherein the undercut is in the form of a shoulder and the engagement member is in the form of a bar-shaped body.
7. The seating furniture as claimed in claim 1 , wherein the hollow forms a pressure collar with a longitudinal groove.
8. The seating furniture as claimed in claim 1 , wherein the braceable clamping bodies form counterparts that can be aligned with one another by a connection of parts that engage in one another.
9. The seating furniture as claimed in claim 8 , wherein the connection has a groove and a tongue which form a fit.
10. The seating furniture as claimed in claim 9 , wherein the tongue forms a clamping bridge for transmitting the tensioning force of tensioning elements to the frame.
11. The seating furniture as claimed in claim 1 , wherein the engagement member is fastened as an attachment piece to a seat part and back part, wherein the seat part and the back part each comprise a sheet-like structure.
12. The seating furniture as claimed in claim 1 , wherein the at least two frames serves as an end frame or as an intermediate frame.
13. The seating furniture as claimed in claim 1 , wherein at least a third frame is fastened between foot parts.
14. The seating furniture as claimed in claim 1 , wherein the engagement member consists of a plastics material.
15. The seating furniture as claimed in claim 1 , wherein the seat part and the back part are in the form of a seat shell.
16. Seating furniture, comprising:
at least two frames which are arranged at a distance horizontally to each other, wherein each frame comprises a top frame part and a bottom frame part;
a seat part and a back part that are configured to be clamped between the top frame part and the bottom frame part so as to be suspended from the at least two frames, wherein the top frame part and the bottom frame part includes a peripheral edge defining a side;
at least one fastener that releasably clamps the top frame part to the bottom frame part, with the seat part and the back part sandwiched between the top frame part and the bottom frame part;
wherein at least one of the top frame part or the bottom frame part includes an elongate hollow that forms an opening in the side and that forms a frame joint;
wherein an engagement member is provided at a side of the seat part and of the back part adjacent the side of the top frame part and the bottom frame part with the opening and is in direct contact with the top frame part and the bottom frame part when positioned within the hollow so as to provide a frictional connection to the top frame part and bottom frame part; and
wherein the hollow has an undercut which forms a stop for securing the clamped engagement member in a form fitting manner.
