Abstract

A system is disclosed for remote control of a driver'"'"'s seat in a vehicle equipped with powder seats but without memory seats function. The system is controlled by remote RF transmitter and auto security system which are responsive to a remote control signal disarming the system. Upon receipt of such signal the system will position the driver'"'"'s seat on a preselected mode to either initial easy access position or a driver position corresponding to the particular transmitter code. In the event an intrusion is detected while the security system is armed, the system automatically moves the driver'"'"'s seat to an alarm position closest to the vehicle'"'"'s dashboard to make it difficult or impossible for an intruder to drive the vehicle.
