Abstract: The invention relates to a back-seat in a station wagon. The back-seat has a seat-back which is divided into a lower portion joined to a seat-bottom and an upper portion displaceable relative to the seat-bottom. The upper portion is joined to horizontal rails which engage fixed rails at the sides of the cargo space. The displaceable rails support an upper floor, which when the upper seat-back portion is in a forwardly displaced position forms a forward extension of the cargo space floor.

Abstract: The invention relates to a seat intended, for example, for automobiles, trains or airplanes, having a back-rest, in which there is arranged a lumbar-support device whose rigidity can be adjusted by turning a wheel mounted on a shaft journalled in the back-rest, and the vertical setting of which can be adjusted by vertically displacing the wheel with subsequent pivoting of the shaft. The lumbar support device comprises a horizontally elongated sheet of flexible material that is bodily vertically displaceable by vertically displacing the wheel, and whose rigidity is adjusted upon turning the wheel by moving toward or away from each other the opposite horizontal edges of the sheet thereby to cause the sheet to bow outwardly to a greater or lesser extent. Turning the wheel winds a filament on the shaft to effect this latter adjustment.
