The covering 220 can be divided here corresponding to the width of the backrests 204.

[0053] The ISOFIX fastening device 121 can be covered by the covering 220 in such a manner that said ISOFIX fastening device continues to be accessible through passage openings 222 (illustrated in FIG. 3) and/or by manual operation of, in particular moving away, for example folding away, the covering 220 upwards or downwards or to the side or by removal of the covering 220.

[0054] The outer side 224 of the covering 220 facing away from the ISOFIX fastening device 121 forms part of the seat surface of the respective vehicle seat 100 or of the seat arrangement 200 with a plurality of seat surfaces.

[0055] The covering 220 can be arranged, for example, on the vehicle seat 100 in such a manner that the passage opening 222 in the covering 220 and recesses in the cushion element or an intermediate space between two cushion elements of the vehicle seat 100 lie one above another and the fastening device 121 is accessible from the outside through them for fastening the child seat 118 to said fastening device 121.

[0056] FIG. 3 shows a perspective illustration of the covering 220 according to FIG. 2 in detail.

[0057] The covering 220 is designed as a front or first covering unit 220 (called front covering unit 220 below for better clarity) and comprises an associated three-dimensionally shaped front or first lining strip 226.1 (also called lining cover).

[0058] The outer side 224 of the front lining strip 226.1 can optionally be designed as a decorative surface. The front covering unit 220, in particular the front three-dimensionally shaped lining strip 226.1, can be divided in its longitudinal extent on the outer side 224 corresponding to the width of the backrests 204. For example, the single-piece front covering unit 220 can be provided for this purpose with separating grooves 230 on the outer side 224.

[0059] Here, depending on the equipping of the backrests 204 without or with ISOFIX fastening devices 121 (illustrated in FIG. 1), the front three-dimensionally shaped lining strip 226.1 can comprise no or at least one passage opening 222 or a plurality of, for example two, passage openings 222 (in the case of only one ISOFIX fastening device 121) or a multiple of two passage openings 222 (in the case of a plurality of ISOFIX fastening devices 121). For example, the front ISOFIX covering unit 220 or three-dimensionally shaped front lining strip 226.1 can be divided in various ways by the separating grooves 230, for example as a 40-60 division of a backrest 204 or a 40-20-40 division of a backrest 204 or similar.

[0060] Owing to the fact that the front covering unit 220 is designed as a three-dimensionally shaped front lining strip 226.1, it can be sewn into a lining, not illustrated specifically, (also called seat lining) or into the seat part cushion 208 or can be sewn with such a lining or with the seat part cushion 208 or a trim for the vehicle seat 100 or with the seat arrangement 200 or fastened in some other way.
