Abstract
The invention relates to a link chain having two rows of chain elements wherein the chain elements of one row are rotatably connected to those of the adjacent row in the chain plane in such a way that each chain element has two rotational axes, of which each one of the two rotational axes of two different chain elements is in adjacent rows, and that the chain elements of one row are connected to one another by means of toothings of their ends in such a way that the chain is flexible in the chain plane, wherein the rotational axes are designed such that the chain remains in a set position.
Claims20
Link chain comprising:
- two or more rows of chain elements, wherein the chain elements of one row are rotatably connected to those of the adjacent row in a chain plane in such a manner that each chain element has two rotational axes;
- wherein each one of the two rotational axes of two different chain elements is in adjacent rows;
- toothing arrangements on facing ends of said chain elements interconnecting the chain elements of one row wherein the chain is flexible in the chain plane, wherein the rotational axes are configured in such a manner that the chain remains in an adjusted position.
A reclining chair, or a sofa comprising:
- a backrest and a seat surface,
- a link chain providing adjustment of said backrest with respect to said seat surface, said link chain having two or more rows of chain elements, wherein the chain elements of one row are rotatably connected to those of the adjacent row in a chain plane in such a manner that each chain element has two rotational axes, wherein each one of two rotational axes of two different chain elements is in adjacent rows;
- and
- said link chain further including toothing arrangements on facing ends of said chain elements interconnecting the chain elements of one row wherein the chain is flexible in the chain plane, wherein the rotational axes are configured in such a manner that the chain remains in an adjusted position.
