Abstract: A motor vehicle seat with a ventilation device having an exhaust channel, the entrance of which connects to an air-permeable contact surface. A porous air-permeable mat is provided adjacent to the contact surface, and an exhaust fan is provided in the exhaust air channel. An intake channel terminates at the mat and has an intake opening. A total air current drawn in by the intake fan and exiting the exhaust channel includes an air current drawn in through the intake opening and an air current drawn in through the contact surface.

Abstract: An inclination adjustment fitting for constituent areas of motor vehicle seats, such as backrests, for example, has a first fitting portion and a second fitting portion. The first fitting portion connected to a first constituent area, and the second fitting portion is connected to a second constituent area. For locking in a desired position of inclination, sets of gear toothing, which mesh with one another, are provided at either portion of the fitting. The sets of gear toothing which mesh to effect the locking are both not provided directly on the portion of the fitting that supports them, but rather, on an intervening element, which is movable, within limits, relative to the corresponding portion of the fitting.

Abstract: A motor vehicle seat with a seat frame and a seat height adjustment device has two guide bars attached to the motor vehicle chassis. The guide bars are pivotable by a propulsion device about a horizontal axis to adjust the height of the seat in various positions of inclination. The guide bars are connected so as to resist torsion, and on the side of the seat opposite the propulsion device, a locking device which is sensitive to inertia is provided between the seat frame and the adjacent guide bar.
