wherein the frame element has at least one fastening element on each of at least two opposite inner sides, and the knitted fabric has a fastening element formed complementarily thereto and arranged on a rear side in each case, the knitted fabric being fastened to the frame element by the fastening elements in such a way that, starting from a front side of the frame element facing the seat part, the knitted fabric engages around the frame element at least partially from the outside inwards and is essentially completely tensioned, and

wherein at least six fastening units are fixedly arranged on the knitted fabric, wherein each of the fastening units includes at least one of the fastening elements,

wherein the fastening elements of the fastening units are arranged on the knitted fabric,

wherein the fastening units are fastened, in particular sewn on, to the knitted fabric on an edge side, in particular opposite one another,

wherein, being of strip-like design, the fastening elements arranged on the fastening units project beyond a base surface of the knitted fabric,

wherein the knitted fabric has an upper tubular section of the knitted fabric with two opening sides, a first opening side being closed, and the upper tubular section of the knitted fabric is arranged to surround the upper area of the frame element,

wherein the fastening elements of the knitted fabric are formed in a hole shape so that they can be positively connected to the complementary hook-shaped fastening elements of the frame element, and

wherein edge areas of the knitted fabric are of a wing-like design so that they can be easily folded around struts for reclamping the frame element.

2 . The vehicle seat according to claim 1 , wherein the knitted fabric is arranged in a free-swinging manner on the front side of the frame element at least in the area of the inner surface, wherein the knitted fabric is arranged in the area of the inner surface either on or above the inner surface or is arranged in sections on or above and inside the inner surface, and wherein the knitted fabric provides the sole support and/or cushioning for a seat user at least in the area of the inner surface.

3 . The vehicle seat according to claim 1 , wherein the frame element encloses a continuous upper area for supporting the head and a lower area having the inner surface for supporting the back, wherein one inner side of the upper area delimits the inner surface from above and three inner sides of the lower area delimits the inner surface laterally and from below, wherein the frame element has at least one fastening element on each of the inner sides delimiting the inner surface, and wherein the fastening elements on the frame element and the knitted fabric are designed in such a way that the fastening of the knitted fabric to the frame element can be released without being destroyed.

4 . The vehicle seat according to claim 1 , wherein the fastening elements on the frame element are in the form of at least one of hooks, strips, hook-and-loop fasteners, zip fasteners or press studs, and wherein at least one of a plurality of different types of fastening elements or only one type of fastening element is provided, in which case at least one of a plurality of fastening elements or one continuous fastening element is arranged on the inner sides of the frame element and distributed over the length of the inner side.

5 . The vehicle seat according to claim 1 , wherein the knitted fabric has a lower section which is essentially planar and directly adjoins the upper section at a front, and wherein the lower section contacts a lower area of frame element from the front and, starting from the front of the frame element, at least partially embraces it from the outside inwards.

6 . The vehicle seat according to claim 5 , wherein the complementary fastening elements of the knitted fabric are arranged on a rear edge side of the open second opening side on the upper section as well as on the side and a bottom edge side of the lower section.

7 . The vehicle seat according to claim 1 , wherein interior equipment of a means of transport, in particular a means of passenger transport, comprising at least one vehicle seat.

8 . A method of manufacturing a backrest part for a vehicle seat according to claim 1 , comprising at least the following steps:

a. Providing a frame element and a knitted fabric, the frame element having at least one fastening element on each of at least two opposite inner sides and the knitted fabric having a fastening element complementary thereto and arranged on the rear side;

b. Placing the knitted fabric against the frame element on a front side of the frame element facing the seat part;

c. Fastening the knitted fabric to the frame element by the fastening element so that the knitted fabric at least partially embraces the frame element from the outside to the inside;

d. Obtaining the backrest part with the knitted fabric at least partially embracing the frame element,

wherein at least six fastening units are fixedly arranged on the knitted fabric, wherein the fastening units include the fastening elements arranged on the knitted fabric such that each fastening unit comprises at least one fastening element, the fastening units being fastened, in particular sewn on, to the knitted fabric on an edge side, in particular opposite one another, and being of strip-like design, the fastening elements arranged on the fastening units projecting beyond a base surface of the knitted fabric.
