DETAILED DESCRIPTION

[0032] A vehicle seat 1 which is shown diagrammatically in FIG. 1 will be described in the following text with the use of three spatial directions which run perpendicularly with respect to one another. A longitudinal direction x runs largely horizontally, in the case of a vehicle seat 1 which is installed in a vehicle, and preferably parallel to a vehicle longitudinal direction which corresponds to the usual driving direction of the vehicle. A transverse direction y which runs perpendicularly with respect to the longitudinal direction x is likewise oriented horizontally in the vehicle, and runs parallel to a vehicle transverse direction. A vertical direction z runs perpendicularly with respect to the longitudinal direction x and perpendicularly with respect to the transverse direction y. In the case of a vehicle seat 1 which is installed in the vehicle, the vertical direction z runs parallel to the vehicle vertical axis.

[0033] The positional specifications and directional specifications which are used, such as for example front, rear, top and bottom, relate to a viewing direction of an occupant seated in the vehicle seat 1 in a normal seating position, the vehicle seat 1 being installed in the vehicle, in a use position suitable for passenger conveying with an upright backrest 4 and, as customary, oriented in the driving direction. The vehicle seat 1 can also be installed, however, in a different orientation, for example transversely with respect to the driving direction.

[0034] The vehicle seat 1 shown in FIG. 1 for a motor vehicle has a seat part 2 and a backrest 4, the inclination of which can be adjusted relative to the seat part 2. An inclination of the backrest 4 can be capable of being adjusted, for example, by a latching fitting or geared fitting.

[0035] The seat part 2 and the backrest 4 of the vehicle seat 1 in each case have a cushion part 6. The cushion part 6 of the seat part 2 and of the backrest 4 is in each case provided with at least one cover 10 which spans the respective cushion part 6. Furthermore, an additional cover 12 which overlays the cover 10 in sections is provided. In the present case, the additional cover 12 extends over the entire width of the seat part 2 and of the backrest 4.

[0036] In the present case, the vehicle seat 1 has two cushion parts 6 with a plurality of adaptation regions 8. In the adaptation regions 8, at least one exchangeable additional cushion 20 can be arranged between the additional cover 12 and the cover 10. As a result, the three-dimensional contour of the adaptation regions 8 can be changed.

[0037] In the present case, the vehicle seat 1 has a plurality of additional cushions 20. In the present case, the plurality of additional cushions 20 are arranged in pairs in a mirror-symmetrical manner with respect to a centre plane which is oriented perpendicularly with respect to the transverse axis y.

[0038] Two of the adaptation regions 8 are arranged in a side region of the cushion part 6 of the seat part 2, in the present case in a region of a side bolster of the seat part 2. Two further adaptation regions 8 are arranged in a side region of the cushion part 6 of the backrest 4, in the present case in the region of a side bolster of the backrest 4.

[0039] FIG. 2 shows a view from above of the seat part 2 of the vehicle seat 1. The additional cover 12 has a first fastener 14a. In order to fasten the additional cover 12 to the cover 10, the cover 10 has a second fastener 14b which cooperates with the first fastener 14a. In the present case, the two fastener 14a, 14b together form a zip fastener.

[0040] In the present case, the zip fastener runs around, in particular runs completely around, the seat part 2. The additional cover 12 can be fastened to the cover 10, in particular over the full periphery, by a first fastener 14a in operative connection with the second fastener 14b.

[0041] FIG. 3 shows the additional cover 12 in a state with fastener 14a, 14b which are separated in each case from one another, the additional cover 12 being folded over in sections.

[0042] FIG. 4 shows the additional cushion 20 with a protective cover. The protective cover preferably surrounds a foam part. The additional cushion 20 has a fastening 22 in sections. In the present case, the fastening 22 is configured as a first half of a hook and loop closure fastener.

[0043] FIGS. 5 and 6 show the side bolster of the seat part 2 with the inserted additional cushion 20. The additional cover 12 has, in sections, a matching fastening 16 which cooperates with the fastening 22 of the additional cushion 20. In the present case, the matching fastening 16 is configured as a second half of the hook and loop closure fastener.

[0044] FIGS. 7 and 8 show different views from the front of the seat part 2 and the side bolster with the additional cushion 20 and the additional cover 12. The illustrated state exists, for example, after the mounting of the additional cushions 20 when the fastener 14a, 14b of the additional cover 12 and of the cover 10 are connected to one another again.

[0045] In the present case, the additional cushions 20a, 20b which are introduced into the vehicle seat 1 are of different configuration by way of example. In particular, the additional cushion 20b of the tunnel-side (in FIG. 8) side bolster of the seat part 2 has a higher thickness than the opposite additional cushion 20a of the door-side side bolster. An adaptation of the door-side side bolster with a comparatively thinner additional cushion 20a or even completely without an additional cushion 20a facilitates entry into the vehicle seat 1 or exit from the vehicle seat 1 for the occupant; whereas the lateral support in the direction of the tunnel side of the seat part 2 is increased by way of an adaptation of the tunnel-side side bolster with a comparatively thicker additional cushion 20b.

[0046] The features which are disclosed in the preceding description, the claims and the drawings can be of significance both individually and in combination for the implementation of the invention in its various refinements, in so far as this is covered by the wording of the independent claims.
