An automobile seat with supporting frame, upholstery, and seat cover includes a seat body and a seat back, as well as at least one seat back region, such as a side wing on the seat back, whose height and shape in its use position extends forward over the central shape of the seat back. An elastic adjustment element and actuation medium for the adjustment element are positioned within the seat back or the side wing. The adjustment element and the deformed region in the seat back such as the side wing are so deformed by the actuation medium when the seat back is tilted forward from the use position into the tilted-forward position that the height of the seat back portion, such as the side wing, extending over the central shape is less than when in the use position.

What is claimed is: 1. An automobile seat with supporting frame, said seat comprising: a seat body adapted to be secured to the floor of a vehicle; a seat back pivotably connected to said seat body about a tilt axis substantially horizontal to said floor, wherein said seat back is adapted to tilt between a use position wherein said seat back is substantially vertical relative to said seat body and a tilted position wherein said seat back is substantially horizontal relative to said seat body, said seat back including: a central portion; and at least one side wing disposed along an edge region of said central region along a longitudinal axis of said seat back, said side wing adapted to extend substantially outwardly and generally perpendicular to a longitudinal plane of said central region at all times; and means for adjusting a distance that said side wing extends outwardly relative to said central region such that when said seat is disposed in said use position, said side wing extends outwardly from said central region at a distance A from said central region and when said seat is disposed in said tilted position, said wing extends outwardly from said central region at a distance less than A from said central region. 2. The automobile seat as in claim 1, wherein said side wing includes a deformable-elastic hoop element having a generally arc shape extending generally outwardly from said central region. 3. The automobile seat as claimed in claim 2 wherein said deformable-elastic hoop element includes a radius, wherein of said radius is larger when said seat is in said use position than said tilted position. 4. The automobile seat as in claim 3, wherein said deformable-elastic hoop element includes a first and a second anchoring area, said first anchoring area connecting said deformable-elastic hoop element with a supporting frame of said seat back, and said second anchoring area connecting said deformable-elastic hoop element with said means for adjusting. 5. The automobile seat as in claim 4, wherein said means for adjusting includes a pull-cable having a first end connected to a distal region of said seat back and a second end is connected proximate said seat body, wherein said second anchoring area is connected to said pull-cable. 6. The automobile seat as in claim 5, wherein a spring tensions said pull-cable towards said distal region of said seat back. 7. The automobile seat as in claim 5 wherein said pull-cable is routed through at least one cable guide affixed to said supporting frame of said seat back. 8. An automobile seat comprising: a seat body adapted to be secured to the floor of a vehicle; a seat back pivotably connected to said seat body about a tilt axis substantially horizontal to said floor, wherein said seat back is adapted to tilt between a first position wherein said seat back is substantially vertical relative to said seat body and a second position wherein said seat back is substantially horizontal relative to said seat body; and at least one cable having a first end disposed proximate a distal end of said seat back and a second end disposed proximate said seat body, wherein at least a portion of said cable runs along an edge region of said seat back along a longitudinal axis of said seat back; and at least one deformable-elastic hoop element disposed along said edge region of said seat back along said longitudinal axis of said seat back, said hoop having a first end that is fixed relative to said seat back and a second end that is secured to said cable, whereby in said first position, said hoop extends substantially outwardly and generally perpendicular to a longitudinal plane of said seat back at a distance A from said seat back and whereby in said second position, said cable and said second end of said hoop move along said longitudinal axis of said seat back such that a distance that said hoop extends outwardly from said seat back is less than A. 9. The seat as claimed in claim 8 further including at least one spring tensioning said cable in said direction said cable moves between said first and said second positions. 10. The seat as claimed in claim 9 wherein said spring is disposed proximate first end of said cable. 11. The seat as claimed in claim 10 further including at least one pulley disposed proximate tilt axis. 12. The seat as claimed in claim 11 wherein said cable is routed through a first and a second cable guide, wherein said first cable guide is disposed within said seat back proximate said tilt axis and said second cable guide is disposed proximate said first end of said cable. 13. The seat as claimed in claim 12 wherein second cable guide is secured said cable and wherein said hoop is secured to said second cable guide such that said second cable guide moves with said cable along said longitudinal axis of said seat back. 14. The seat as claimed in claim 12 wherein a location of said second cable guide is fixed relative to said seat back.
