[0048] FIG. 1 shows a backrest 1 of a vehicle seat according to the prior art, a lining element 2 according to the prior art being arranged on the rear face thereof.
[0049] This lining element 2 is shown separately in FIG. 2 and serves for covering the backrest 1 on the rear face.
[0050] FIG. 3 schematically shows options for adjusting a vehicle seat according to the prior art, in particular options for adjusting a backrest 1. In the backrest 1, for example, the height of a head restraint, the width in the shoulder region and the width in the lumbar region are adjustable.
[0051] FIG. 4a shows a first embodiment of a lining element according to the invention 2 in a schematic sectional view. The lining element 2 comprises a soft lining part 2.1 which is preferably formed from silicone and/or from a woven fabric, a plurality of, preferably six, solid lining parts 2.2 which preferably consist of thermoplastic material being fastened to the rear face thereof. Optional, soft intermediate elements 2.3 are arranged in each case between adjacent solid lining parts 2.2. On a surface 2.4 on the rear face of the lining element 2, the solid lining parts 2.2 which taper toward the front in each case have a small spacing from the respectively adjacent solid lining part 2.2. In the upper region of the lining element 2 an optional fastening element 2.5 is shown schematically, the lining element 2 being fastenable thereby to a backrest 1, not shown.
[0052] FIG. 4b shows an associated schematic sectional view with a deformation toward the rear which may occur by a person 3 sitting down in the seat or pushing the seat toward the rear. In this case, the lining element 2 is deformed in a convex manner toward the rear. This deformation is possible in a simple manner by the flat, soft lining part 2.1 bending, without having to be stretched as a whole. The spacings on the rear face between the solid lining parts 2.2 are enlarged at the same time. As a result, the comfort of the person is improved.
[0053] FIG. 4c shows an associated schematic sectional view with a deformation toward the front which may occur by an item of luggage 4 being pushed toward the front against the seat, for example in the event of an accident. In this case, the lining element 2 does not deform in a concave manner, or at any rate only slightly, toward the rear. It is possible to limit this deformation in a simple manner since the flat, soft lining part 2.1 is bendable. The spacings on the rear face between the solid lining parts 2.2 are initially reduced at the same time; as soon as the solid lining parts 2.2 come into contact with one another, a further deformation in the specified direction is substantially prevented, whereby the safety of the person, not shown here, is improved.
[0054] FIG. 5 shows a second embodiment of a lining element 2 according to the invention in a view from the rear. The lining element 2 has four plate-shaped solid lining parts 2.2 which are arranged superimposed and solid lining parts 2.2 which in each case are arranged laterally. All of the lining parts 2.2 are arranged on a common planar, soft lining part 2.1.
[0055] FIG. 6 shows the second embodiment of a lining element according to the invention 2 in a side view, wherein two solid lining parts 2.2 are arranged on one side adjacent to one another, wherein a strip of the soft lining part 2.1 is configured between the two solid lining parts 2.2. As a result, when a side airbag arranged in the backrest 1 is deployed, the solid lining part 2.2 shown to the left is able to fold away to the side so that the airbag may be deployed without the risk of a component of the lining element 2 splintering. In this case, the strip of the soft lining part 2.1 which is configured between the two solid lining parts 2.2 functions as a hinge.
[0056] FIG. 7 shows a third embodiment of a lining element 2 according to the invention in a schematic sectional view. The lining element 2 comprises four plate-shaped solid lining parts 2.2 on the rear face, said solid lining parts being arranged in the soft lining part 2.1. The lining element 2 permits a deformation toward the rear and counteracts a deformation toward the front.
[0057] FIG. 8 shows a fourth embodiment of a lining element 2 according to the invention in a schematic view from the rear. This embodiment corresponds substantially to the embodiment shown in FIG. 5 but has an optional additional device which also counteracts a deformation toward the front. This device is arranged on the front face on the lining element 2, i.e. is not visible when the lining element 2 is mounted, and comprises two substantially vertically arranged optional wires as deformation-limiting traction elements 2.7. Each traction element 2.7 is fastened in each case by means of five fixing elements 2.6 to each of the five plate-shaped solid lining parts 2.2 and preferably attached both at the top and at the bottom to a frame element of the lining part. In the event of the action of a force from the rear toward the front against the lining element 2, the traction elements 2.7 tighten and are activated so that a deformation toward the front is additionally counteracted. It is alternatively possible that the traction element 2.7 are not configured as wires but as elements which stiffen when deformed toward the front.
[0058] A solid lining part 2.2, and spaced apart therefrom a side lining part S, are arranged adjacent to one another on at least the left-hand side, wherein a strip of the soft lining part 2.1 is configured between this solid lining part 2.2 and the side lining part S. As a result, when a side airbag arranged in the backrest 1 is deployed, the solid lining part 2.2 shown to the left may be folded away to the side so that the airbag may be deployed without the risk of a component of the lining element 2 splintering. In this case, the strip of the soft lining part 2.1 which is configured between the two solid lining parts 2.2 functions as a hinge. The possibility of folding away to the side is shown by an arrow.
[0059] According to a first alternative, the side lining part S is also a solid lining part 2.2, i.e. a component of the lining element 2. According to a second alternative, the side lining part S is a component of a fixed frame part of the seat, i.e. is not a component of the lining element 2.
[0060] FIGS. 9a and 9b show the fourth embodiment of the lining element 2 according to the invention. The lining element 2 comprises six relatively wide plate-shaped solid lining parts 2.2, with a rear view in an overlapping arrangement, wherein the solid lining parts 2.2 partially overlap. All of the solid lining parts 2.2 are incorporated in the common soft lining part 2.1. The overlapping may be configured in a stepped manner such that adjacent solid lining parts 2.2 are in contact with one another when deformed toward the front, so that a hinge action is limited, as described above.
