[0006] According to the invention, this object is achieved by a vehicle seat comprising at least a seat part and a backrest arranged pivotably on the seat part (in other words, the vehicle seat comprises at least one seat part and a backrest arranged pivotably on the seat part), wherein the backrest comprises at least a lower backrest section and an upper backrest section arranged on the lower backrest section, and wherein the upper backrest section is pivotable relative to the lower backrest section in the direction of the seat part. The upper backrest section comprises at least one seat belt arrangement and a storage surface facing away from the seat part.

[0007] In particular, the upper backrest can be equipped with a belt-integrated component. The vehicle seat can be formed (designed) as a belt-integrated seat. The surface of the upper backrest facing away from the seat part (ie the back side) can be formed as a storage surface.

[0008] Alternatively or optionally, the seat part and the backrest can be additionally fixed on the base part, which constitutes a seat, namely the seat part and the backrest. The base part can be a base structure, in particular a frame structure and a load-bearing structure, which can be connected to the vehicle floor and / or the longitudinal adjustment device.

[0009] Since the upper backrest section includes at least one seat belt arrangement, the vehicle seat can be used as a seat with an integrated safety system and as a functional element, for example as a storage rack and / or a table. The vehicle seat can be used multifunctionally. The vehicle seat can be a commercial vehicle seat, for example an occupant seat arranged in the cab of a commercial vehicle.

[0010] Advantageous embodiments which can be used individually or in combination with one another are the subject matter of the dependent claims.

[0011] The seat belt device can be fastened to the upper backrest frame. For vehicle seats with a seat belt device or with integrated components, a single fastening point or all fastening points of the seat belt device can be connected to the vehicle seat.

[0012] The upper backrest part, in particular the upper backrest frame, can in particular comprise two side frame parts and a transverse frame part connected to the side frame parts, wherein the seat belt device can be arranged in the connecting area between one of the side frame parts and the transverse frame part. For example, the seat belt device can be arranged in a corner area of ​​the upper backrest frame. The upper backrest frame can be formed substantially in a U-shape.

[0013] The seat belt arrangement can include at least one belt guide and / or a belt retractor and / or a belt tensioner and / or a belt force limiter.

[0014] The backrest can be arranged in a normal position (especially a seat position) at a first angle relative to the seat part and / or the base part, wherein the upper backrest and the lower backrest together form a planar backrest surface. The normal position can be an upright seat position and, for example, a starting position, in which the backrest can be arranged to be slightly inclined relative to the seat part and / or the base part. The plane or axis passing through the backrest can be arranged to form an angle with the vertical axis, for example in a direction away from the seat part and / or the base part. The backrest can also be adjusted between a normal position and a comfortable position. In the comfortable position, the backrest can be tilted backwards (that is, away from the seat part and / or the base part) at a larger angle.

[0015] The upper backrest section can be formed so that, in the normal position, it can be pivoted relative to the lower backrest section into a folded position. In particular, the upper backrest section can be formed so as to be pivotable in the direction of the seat section and / or the base section. In the folded position, the back side of the upper backrest section can be used as a shelf and / or a table.

[0016] The upper backrest can be formed so that it can be pivoted relative to a plane defined by the normal position within a free pivoting area (range) of at least 75° to 85°, in particular 80° (that is, it can be pivoted about the free pivoting area by at least 75° to 85°, in particular 80°, relative to the plane defined by the normal position). In the folded position of the upper backrest, the lower backrest can still be in the normal position, in particular a slightly inclined normal position.

[0017] After or during entry into the folded position, the lower backrest section can be pivoted by a second angle relative to the vertical axis (e.g. also relative to the seat part and / or the base part) until the lower backrest section is arranged essentially perpendicular to the seat part and / or the base part or slightly inclined towards the seat part and / or the base part. In particular, the lower backrest section can be pivoted in the direction of the seat part and / or the base part until the upper backrest section is arranged essentially parallel to the horizontal axis. The lower backrest section can be adjusted by a second angle in the direction of the seat part and / or the base part forward beyond the vertical axis. In this way, it can be ensured that the upper backrest section is completely brought into a horizontal folded position, in particular a horizontal shelf position and / or table position, relative to the seat part and / or the base part or relative to the vehicle floor.

[0018] The lower backrest can be formed so that it can be pivoted about the pivoting area relative to the vertical axis when the upper backrest is operated into the folded position. In particular, the lower backrest can be relatively pivoted in the direction of the seat part and / or the base part. The lower backrest can be pivoted forward beyond the vertical axis in the direction of the seat part. Thereby, the upper backrest can be adjusted to a horizontal folded position, in particular a shelf position and / or a table position. The user can make such horizontal adjustments to achieve the horizontalization of the shelf and / or the table on a sloping driveway, on a hillside or on an inclined driveway.

[0019] The upper backrest section can be arranged pivotably on the lower backrest section via a first fitting, wherein the first fitting can be operated via a first operating element arranged on the backrest.

[0020] The lower backrest part can be arranged pivotably on the seat part and / or the base part via a second fitting, wherein the second fitting can be operated via a first operating element or via a second operating element arranged on the backrest.

[0021] When the first operating element is operated, the locking system of the upper backrest which keeps the upper backrest locked in the normal position can be unlocked. Subsequently, the upper backrest can be folded forward. The folding movement of the upper backrest can be realized automatically, for example, by a spring element. The folding movement of the upper backrest can be realized manually, for example, by pressing.

[0022] The first fitting may comprise a pre-tensioned spring element, for example a helical spring.

[0023] The upper and lower backrest parts can perform a combined folding movement, wherein the locking system of the upper and lower backrest parts can be unlocked by actuating the first operating element.

[0024] Alternatively, the lower backrest can remain locked in the normal position during the folding movement of the upper backrest. After the upper backrest has been brought into the folded position, the first operating element can be operated again or the second operating element can be operated to unlock the lower backrest so that it can be adjusted in the direction of the seat part and / or the base part, in particular pivoted. The folding movement of the lower backrest can be automatically realized, for example by a spring element. The folding movement of the lower backrest can be realized manually, for example by pressing.

[0025] The second fitting may comprise a pre-tensioned spring element, for example a helical spring.

[0026] The first operating element can be a pulling element, in particular a pull belt or a pull rod. The second operating element can be a pulling element, in particular a pull belt or a pull rod.
