Safety Device for a Motor Vehicle
First Claim
1. A safety device for a motor vehicle, comprising:
- an active headrest which is provided on a backrest of a vehicle seat; and
a control unit which actuates a headrest-deployment device as a function of the evaluation of the signals from a crash sensor when an accident event occurs in such a way that the active headrest is deployed into a headrest position which is optimum in terms of occupant safety, wherein the control unit actuates at least one component of the vehicle seat as a function of an evaluation of data which is relevant in terms of driving safety before the expected accident event occurs in such a way that the vehicle seat is moved to an optimum starting position for deploying the active headrest when the accident event occurs.

Abstract
A safety device for a motor vehicle, includes an active headrest which is provided on a backrest of a vehicle seat and a control unit which actuates a headrest-deployment device as a function of the evaluation of the signals from a crash sensor when an accident event occurs such that the active headrest is deployed into a headrest position which is optimum in terms of occupant safety. The control unit actuates at least one component of the vehicle seat as a function of the evaluation of data which is relevant in terms of driving safety before the expected accident event occurs such that the vehicle seat is moved to an optimum starting position for deploying the active headrest when the accident event occurs.

11. A method for a safety device for a motor vehicle, comprising an active headrest which is provided on a backrest of a vehicle seat and a control unit, the method comprising the acts of:
-
actuating, by the control unit, a headrest-deployment device as a function of the evaluation of the signals from a crash sensor when an accident event occurs in such a way that the active headrest is deployed into a headrest position which is optimum in terms of occupant safety; and actuating, by the control unit, at least one component of the vehicle seat as a function of an evaluation of data which is relevant in terms of driving safety before the expected accident event occurs in such a way that the vehicle seat is moved to an optimum starting position for deploying the active headrest when the accident event occurs. - View Dependent Claims (12, 13, 14, 15)
