- the support area has a relief zone which is designed to relieve a spine of the passenger.
- the invention also relates to a vehicle seat for a vehicle with the backrest and a vehicle with the vehicle seat.
- Backrests for vehicle seats often have upholstery to allow comfortable supported leaning against the backrest. Also known are low-weight bucket seats with little or no upholstery.
- a vehicle seat of lightweight construction is disclosed in publication DE 199 12 182 A1.
- the vehicle seat has an approximately L-shaped, tubular frame which is shaped like a spine.
- the vehicle seat has a seating area, the seating area being connected to the frame.
- the vehicle seat has shell parts which form a backrest area and are suspended from the frame.
- the object of the invention is to provide a functionally improved, ergonomically advantageous backrest for a vehicle seat. This object is achieved by a backrest for a vehicle seat having the features of claim 1, by a vehicle seat for a vehicle with the backrest according to claim 13 and by a vehicle with the vehicle seat according to claim 14. Preferred or advantageous embodiments of the invention result from the subclaims, the following description and/or the accompanying figures.
- a backrest for a vehicle seat for example for a car, is proposed.
- the vehicle seat can be used as a seat in a front row of seats in the car, in particular other than a driver's seat or passenger seat.
- the vehicle seat can also be designed as a seat in a rear row of seats of the vehicle. It is also possible that the vehicle seat is designed as a seat for a truck or for a bus, train or aircraft.
- the backrest can preferably be connected to a seat cushion of the vehicle seat.
- a passenger of the vehicle can sit on the seat cushion and lean against the backrest with his back when the backrest is connected to the seat cushion.
- the backrest can be moved with the seat cushion, in particular pivoted, connected.
- the backrest can preferably be transferred from an upright position, in which it is arranged essentially perpendicularly to the seat cushion, into an inclined position, the backrest being arranged in the inclined position, for example, at an obtuse angle to the seat cushion.
- the backrest has padding.
- the padding can, for example, be made of a foam material, for example a flexible foam, cold foam or a composite foam material.
- the foam can, for example, include polyurethane.
- the upholstery is preferably supported by a back structure such as metal or plastic. In particular, the backrest structure is foamed around with the foam from which the upholstery is formed.
- the upholstery forms a support area for the passenger's back.
- the support area is preferably arranged centrally in the backrest and is directed in the direction of the passenger's line of sight, in particular when he is sitting on the seat cushion and/or in the vehicle seat.
- the upholstery forms two side panels of the backrest, which delimit the support area laterally at least in sections.
- the support area extends between the two side panels in relation to a transverse extent of the backrest, which is directed essentially horizontally to the viewing direction.
- the support area preferably extends over the entire length of the backrest, in particular from a lower end on the seat cushion side to an upper end on which a headrest of the vehicle seat rests can be arranged.
- the passenger can preferably lean with his back in the support area and/or be supported on it.
- the support area has a relief zone.
- the relief zone is designed to relieve a spine of the passenger.
- the relief zone is preferably designed to relieve the spine by partially or completely reducing a pressure that acts on the spine through the padding when leaning against it.
- the relief zone is formed as a recess in the padding.
- the recess may be in the form of an elongate and/or rectilinear groove or in the form of an elongate and/or rectilinear channel.
- the indentation has at least one radius and/or at least one course of a radius in a cross section through the padding.
- the depression is preferably bent and/or curved in cross section, for example in the form of a semicircle.
- the indentation can have a polygonal cross-section.
- a transition between the outside of the padding and the depression can have a bevel, a radius and/or a radius profile. This can have the advantage that the passenger leaning against the support area does not find a transition between the outside and the depression uncomfortable.
- the indentation runs vertically or essentially vertically, in particular when the backrest is in the upright position.
- the recess extends in the same direction as the longitudinal extent of the backrest.
- the depression has a length which is at least 25%, preferably at least 40%, in particular at least 60% and/or at most 85% of the total length of the support area.
- the recess can be based on the longitudinal extension of the backrest be arranged centrally in the support area. In the context of the invention, however, it is preferred that the depression is arranged in relation to the longitudinal extension in a lower section of the support area, which is provided, for example, to support the loins of the passenger.
- the indentation extends upwardly from the lower end of the backrest into the support area.
- the depression can extend from the lower end of the backrest or from the lower section of the support area to an upper section of the support area, which is provided in particular to support the shoulders of the passenger.
- the depression is arranged centrally in relation to a transverse extension of the backrest.
- the depression is preferably arranged centrally between the side walls of the backrest.
- the depression is made in the upholstery where the spine runs when the passenger leans against the support area.
- the depression has an overall depth of at least 8 mm, preferably at least 10 mm, in particular at least 15 mm and/or at most 25 mm. It is possible within the scope of the invention for the depression to have a plurality of sections with different overall depths along its longitudinal extent. Preferably, at least one of the sections has a different, e.g., smaller or larger, depth than the remaining sections. For example, due to the different depths in the sections, the natural shape of the spine We can be taken into account, in particular due to a curvature of protruding vertebrae when sitting. In particular, one or more sections with a greater overall depth than the other sections can be provided for the areas of the spine in which one or more vertebrae protrude further than others when leaning against the backrest.
- the indentation has a width of at least 35 mm, preferably at least 40 mm, in particular at least 45 mm and/or at most 65 mm in the transverse extension of the backrest.
- the indentation is integrated into the upholstery during and/or during its manufacture.
- the indentation can be made in the cushion easily and inexpensively in a common production step.
- the backrest has a cover.
- the cover can, for example, be made of fabric, in particular a woven or knitted fabric, made of leather or imitation leather.
- the upholstery is preferably covered with the cover at least in sections, preferably completely. In particular, the cover covers the upholstery at least in sections, preferably completely.
- the cover completely covers the depression.
- the reference extends beyond the depression.
- the cover forms an uninterrupted, continuous, level and/or smooth visible side in the support area. It is advantageous that the indentation is invisible or at least unobtrusively covered by the cover extending above it. This can be particularly advantageous from an optical point of view.
- a vehicle with the vehicle seat according to the previous description and/or according to claim 13 forms a further subject matter of the invention.
- FIG. 1 shows a backrest for a vehicle seat with an upholstery which has a support area for a back of a passenger in the vehicle, the support area having a relief zone;
