Piece of seating furniture and fitting therefor

Abstract

The prior art discloses a piece of seating furniture ( 10 ), in particular of the armchair or sofa type, having a seat surface ( 14′ ) and a legrest ( 18 ) which is displaceable between a stowed position in which the legrest ( 18 ) is arranged beneath the seat surface ( 14′ ) in the vertical direction ( 6 ) of the furniture, and a use position in which the legrest ( 18 ) is arranged in front of the seat surface ( 14 ′) in the longitudinal direction ( 4 ) of the furniture. Provision is made there for the legrest ( 18 ) to be configured with a variable length by two mutually displaceable fitting portions ( 30, 40 ) of the legrest ( 18 ), and for a force to be able to be applied to the two fitting portions ( 30, 40 ) of the legrest by a spring portion ( 53 a; 54 a; 55 a; 56 a; 57 a; 58 a ) of a spring device ( 50 ), said spring portion ( b 53 a; 54 a; 55 a; 56 a; 57 a; 58 a ) acting between a first force application point ( 33; 34; 35; 36; 37; 38 ) at a first of the two fitting portions (30) and a second force application point ( 43; 44; 45; 46; 47; 48 ) at a second of the two fitting portions ( 40 ). In order to improve such a piece of seating furniture, it is proposed that the two force application points ( 33; 34; 35; 36; 37; 38; 43; 44; 45; 46; 47; 48 ) are offset with respect to one another in a transverse direction of the furniture ( 2 ), such that the spring portion ( 53 a; 54 a; 55 a; 56 a; 57 a; 58 a ) takes up a diagonal direction of extent, and/or that the spring portion ( 53 a; 55 a; 56 a; 57 a; 58 a ) is configured as an elastomer spring portion. Use for achieving a cost-effective, reliable and easily assemblable variable-length legrest and in particular a comparatively wide legrest.
