1. A longitudinal seat adjustment device (1), comprising:
a rail (10) running along a longitudinal axis (X);
a slide (20) with an electric drive device (40) through which the slide can be moved along the longitudinal axis (X) of the rail (10); and
a first control unit (15) and a second control unit (25),
wherein the first control unit (15) is arranged immovably with respect to the rail (10) and the second control unit (25) is arranged on the slide (20),
wherein the first control unit (15) and the second control unit (25) are connected via an electrical conductor (50) which is energized by a voltage source (4) with a supply voltage (S1) such that the first control unit (15) and the second control unit (25) are each directly powered by voltage source (4),
wherein the second control unit (25) is configured to control the drive device (40), and
wherein the first control unit (15) and the second control unit (25) communicate via a communication signal (S2) that is modulated over the supply voltage.
