Seating furniture with armrests

The invention relates to seating furniture with an armrest which is adjustably arranged on an armrest support.

It is known that in seating furniture both the height of the armrest and its laterally measured distance can be adjusted do. The technical solutions for the adjustments are sometimes complex, sometimes the adjustment is problematic,

The invention is based on the object of providing seating furniture of the known type Art to be designed so that an adjustment of the armrest area forwards or backwards is possible in a simple manner is.

This object is achieved according to the invention in that the armrest support on the seat support or seat in a sloping backwards or upwards sloping position is attachable,

With such a construction, the two different Types of attachment of the armrest support the location

The armrest support 1 'is slidably guided in sliding pieces 6. A fitting 7 is connected to a push button 5 via a pin 7a. The fitting 7 is under the action of a Compression spring 8. Within the armrest support 1 'are one below the other arranged, merging round through openings 10 are provided, the side surfaces of which in the axial direction conical. The fitting piece 7 can fall into these round through openings. The adapter is used to unlock disengaged by pressing the push button and then move the armrest 2 upwards or downwards and locked in the specified position by releasing the push button 5.
