Abstract

The invention relates to a vehicle seat having a seat part and a backrest part, in which the backrest part has a frame element enclosing an inner surface and a knitted fabric arranged on the frame element, the frame element having at least one fastening element on each of at least two opposite inner sides and the knitted fabric each having a fastening element formed complementarily thereto and arranged on the backside, wherein the knitted fabric is fastened to the frame element by the fastening elements in such a way that the knitted fabric at least partially embraces the frame element from the outside inwards starting from a front side of the frame element facing the seat part and is substantially completely tensioned.

First claim

What is claimed is:

1 . A vehicle seat having a seat part and a backrest part, wherein the backrest part comprises a frame element including an inner surface and a knitted fabric arranged on the frame element,
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 the 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.

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, the knitted fabric being arranged in the area of the inner surface on or above the inner surface or in sections on or above and inside the inner surface, the knitted fabric providing 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, one inner side of the upper area delimiting the inner surface from above and three inner sides of the lower area delimiting the inner surface laterally and from below, the frame element having at least one fastening element on each of the inner sides delimiting the inner surface, the fastening elements on the frame element and the knitted fabric being 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 hooks, strips, hook-and-loop fasteners, zip fasteners or press studs, a plurality of different types of fastening elements or only one type of fastening element being provided, in which case a plurality of fastening elements or one continuous fastening element are arranged in each case on the inner sides of the frame element, distributed over the length of the inner side.

5 . The vehicle seat according to claim 1 ,
wherein
the knitted fabric has an upper tubular section of knitted fabric with two opening sides, a first opening side being closed, the upper tubular section of knitted fabric being arranged to surround the upper area of frame element, the knitted fabric having a lower section which is essentially planar and directly adjoins the upper section at the front, the lower section contacting the lower area of frame element from the front and, starting from the front of the frame element, at least partially embracing 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 the rear edge side of the open second opening side on the upper section and on the side and bottom edge side of the lower section.

7 . The vehicle seat according to claim 1 ,
wherein
at least two, in particular at least four, fastening units are fixedly arranged on the knitted fabric, whereas the fastening units having the fastening elements arranged on the knitted fabric and each fastening unit comprising at least one fastening element, the fastening units being fastened, in particular sewn on, to the knitted fabric on the 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.

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

9 . 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.
