Abstract

A vehicle seat for a motor vehicle is disclosed which includes a seat part having a seat cushion, a seat cover and a fastening device for fixing the seat cover to the seat part. The vehicle seat also includes a back part with a seat cushion, a seat cover and a fastening device for fixing the seat cover to the seat back. The seat cover includes an upholstery portion and an elastic element to avoid major tensile forces on the upholstery portion and a permanent elongation of the seat cover resulting from a seated occupant.

Claims

1-15. -15. (canceled)

16. A vehicle seat for a motor vehicle comprising:

a seat bottom having a bottom cushion, a seat cover and at least one fastening device for fixing the seat cover; and

a seat back having a back cushion, a seat back cover and at least one fastening device for fixing the seat back cover,

wherein at least one elastic element is connected to the seat cover and configured to minimize tensile forces on and elongation of at least one of the seat cover.

17. The vehicle seat according to claim 16, wherein the elastic element comprises an elastic strip.

18. The vehicle seat according to claim 17, wherein the elastic element is selected from the group consisting of an elastic fabric and a rubber material, wherein the seat cover and the fastening device are of a material other than the elastic element.

19. The vehicle seat according to claim 16, wherein the seat cover comprises a material having a modulus of elasticity which is in the range of two (2) to twenty (20) times greater than a modulus of elasticity of the elastic element.

20. The vehicle seat according to claim 16, wherein the at least one fastening device comprises a retaining strip.

21. The vehicle seat according to claim 16, wherein the at least one fastening device comprises a retaining strip and the length of the elastic element fastened to the retaining strip substantially corresponds to the length of the at least one fastening device.

22. The vehicle seat according to claim 16, wherein the seat bottom further comprising a trim channel, and wherein at least one of the fastening device and the elastic element is at least partially arranged within a trim channel.

23. The vehicle seat according to claim 22, wherein the trim channel is formed in the bottom cushion.

24. The vehicle seat according to claim 16, wherein the elastic element is secured to fastening device with a seam connection.

25. The vehicle seat according to claim 16, wherein the seat bottom further comprises a seat center and a side bolster.

26. The vehicle seat according to claim 25, wherein the seat cover comprises a first portion enveloping the seat center and having the elastic element secured to a lateral edge thereof, a second portion enveloping the side bolster and having the fastening device secured to a lateral edge thereof, and a seam connection between the elastic element and the fastening device.

27. The vehicle seat according to claim 16, wherein the seat cushion comprises an elastic foam material.

28. The vehicle seat according claim 16, wherein the seat cover comprises a leather material.

29. A motor vehicle comprising at least one vehicle seat according to claim 16.

30. A vehicle seat for a motor vehicle comprising:

a seat part having a shell supporting a cushion; and

a cover enveloping the cushion and including a first portion having a retaining strip secured along an first edge thereof and a second portion having an elastic element secured along a second edge thereof, wherein the elastic element is secured to the retaining strip at a seam connection and is configured to minimize tensile forces on and elongation of at least one of the first and second portions of the cover.

31. The vehicle seat according to claim 30 further comprises a trim channel formed in the cushion, wherein at least one of the retaining strip and the elastic element is at least partially arranged within the trim channel.

32. The vehicle seat according to claim 30, wherein the cushion comprises a side bolster and a center portion, wherein the first portion of the cover envelopes the side bolster and the second portion of the cover envelopes the center portion.

33. The vehicle seat according to claim 30, wherein the cover comprises a material having a modulus of elasticity which is in the range of two (2) to twenty (20) times greater than a modulus of elasticity of the elastic element.

34. The vehicle seat according to claim 30, wherein the seat part comprises a seat bottom.

35. The vehicle seat according to claim 30, wherein the seat part comprises a seat back.
