A motor vehicle seat includes a seat frame which is pivotably coupled to a back rest. A tilt adjustment device has a first hinge portion secured to the back rest and a second hinge portion rigidly connected to the car body for tilting the back rest about a horizontal tilt axis which is located at a height greater than the horizontal pivot connecting the back rest to the seat frame. The forward portion of the seat frame is coupled to the car body such that the height and longitudinal position of the seat frame are adjustable. The horizontal pivot connecting the back rest to the seat frame is also adjustable in height and longitudinal position. In this manner, when the back rest is tilted, the seat portion is moved forward or back so that the hip joint location of the passenger remains substantially unchanged. Preferably, the front portion of the seat frame is coupled to a support region that is fixed relative to the car body by an adjustable length connecting linkage, so that the tilt angle of the seat can be adjusted independent of the tilt mechanism for the back rest.
