A safe driver seat unit in a motor vehicle includes a seat supported on two rails by four ball bearings mounted in the seat legs, and a locking arrangement having a locking effect and requiring less electric current than previously to actuate. In a normal position of the seat, the springs provided in front of the seat are compressed and an impacting electromagnetic controller locks the seat. When a collision takes place, a deformation of sensors will turn on the power to unlock the seat, and then the biased springs force the seat to move backwardly away from the dangerous area, while the braking electromagnetic controller automatically brakes the motor vehicle.
