Abstract: A height adjustment device for a component of a vehicle seat may have at least one drive unit having a motor and two height adjustment units. A shaft is arranged between each one of the height adjustment units and the motor and makes it possible to transmit a rotation of the motor to the respective height adjustment unit.

Abstract: An adjusting device for a vehicle seat for adjusting a component of the vehicle seat, may have a tube, a motor and a pinion which is drivable by the motor. The motor and the pinion may be arranged in the tube. In addition, a vehicle seat may have a transverse tube, a component which is movable relative to the transverse tube and the adjusting device for adjusting the component relative to the transverse tube.

Abstract: A vehicle seat may have adjustment kinematics and a drive device for driving the adjustment kinematics. The adjustment kinematics may have at least one movable rocker and a transverse tube which is mounted rotatably about an axis of rotation. An end region of the rocker may be connected to the transverse tube for rotation therewith. A toothed segment which is curved about the axis of rotation may be connected to the transverse tube for rotation therewith, and, in order to drive the adjustment kinematics, the toothed segment is rotatable about the axis of rotation by the drive device.

Abstract: An automatic cost generation apparatus is provided for automatically converting user supplied definitions/requirements into cost parameters for use by a cost-based supply chain optimizer. In one example, this is achieved by generating a linear programming model that incorporates the requirements/definitions as a set of linear constraints. The linear programming model is automatically solved so as to yield a cost model, from which costs are extracted for use by the cost-based optimizer. By first formulating requirements/definitions as linear constraints within a linear programming model, the solution to the model therefore yields a cost model that satisfies the constraints, i.e. a cost model that satisfies the requirements. Hence, requirements/definitions initially provided by the user are thereby automatically converted into a cost model that incorporates costs that can be used during supply chain optimization.
