Adjustment device for a motor vehicle seat
First Claim
1. An adjustment device for a motor vehicle seat comprising an electric motor, a gear connected to said electric motor, a mechanical adjustment unit connected to said gear and a control circuit, at least one sensor being associated with said control circuit for detecting a critical situation of said motor vehicle and said control circuit providing an operating voltage for said electric motor, wherein said control circuit provides in addition to said normal operating voltage, an overvoltage for supplying said electric motor, said normal operating voltage is applied in a normal driving condition of said motor vehicle in which said sensor does not deliver any signal and said overvoltage is applied at said electric motor in a driving condition after said sensor has delivered a signal indicating that a critical situation of said motor vehicle is present, said overvoltage being at least 150% of said value of said normal operating voltage.

Abstract
An adjustment device for a motor vehicle seat that includes an electric motor, a gear connected to the electric motor, a mechanical adjustment unit connected to the gear and a control circuit, at least one sensor being associated with the control circuit for detecting a critical situation of the motor vehicle and the control circuit providing an operating voltage for the electric motor, characterized in that the control circuit provides as an alternative, in addition to the normal operating voltage, an overvoltage for supplying the electric motor, that the normal operating voltage applies in a normal driving condition of the motor vehicle in which the sensor does not deliver any signal, that the overvoltage applies at the electric motor in a driving condition after the sensor has delivered a signal indicating that the driving condition is no longer normal and that the overvoltage is at least 150% of the value of the normal operating voltage, more specifically at least 200% of the value of the normal operating voltage.
