Method for automatically adjusting a headrest of a motor vehicle seat, and device for carrying out said method
First Claim
1. A method for automatically adjusting a headrest of a motor vehicle seat, wherein the headrest is individually adjustable for a passenger occupying the motor vehicle seat with a sensor array and an electronically controlled adjusting device configured to adjust the headrest to an adjusted position defined as optimal as possible for absorbing acceleration forces acting on a head of the passenger in a case of crash, wherein the adjusting device is controllable via a control unit which evaluates at least one signal of at least one sensor in order to control the adjustment of the headrest with the adjusting device, and wherein at least one signal from the at least one sensor serves to detect an occupation of the motor vehicle seat by a passenger, the method comprising:
- transferring the headrest to a predetermined safety position in response to at least one first signal received by the control unit, the safety position being independent of a position of a passenger'"'"'s head, wherein the safety position is different from a prior adjusted position or the same as a prior adjusted position; and
adjusting the headrest in response to at least one second signal individually to the position of the passenger'"'"'s head and depending on the occupation of the motor vehicle seat associated with the headrest.

Abstract
A method for automatically adjusting a headrest of a motor vehicle seat, which can individually be adjusted to a passenger occupying the motor vehicle seat with a sensor array and an electronically controlled adjusting device such that the headrest is in an adjusted position which is defined as optimal as possible for absorbing acceleration forces acting on the head of the passenger in a case of crash is provided. The adjusting device can be controlled via a control unit which evaluates at least one signal of at least one sensor, in order to control the adjustment of the headrest with the adjusting mean. At least one signal from the at least one sensor serves to detect an occupation of the motor vehicle seat by a passenger.

16. A device for automatically adjusting a headrest of a motor vehicle seat, the headrest being individually adjustable for a passenger occupying the motor vehicle seat, the device comprising:
-
a sensor array; an electronically controlled adjusting device configured to adjust the headrest to an adjusted position defined as optimal as possible for absorbing acceleration forces acting on a head of the passenger in a case of crash; a control unit configured to control the adjusting device, the control unit configured to evaluate at least one signal from at least one sensor in order to control the adjustment of the headrest with the adjusting device; wherein at least one signal from the at least one sensor serves to detect an occupation of the motor vehicle seat by a passenger; wherein after at least one first signal is received by the control unit, the headrest is transferred into a predetermined safety position independent of a position of the passenger'"'"'s head, and wherein the safety position is different from the adjusted position or the same as a prior adjusted position; wherein in response to at least one second signal, the headrest is adjusted individually to the position of the passenger'"'"'s head and depending on the occupation of the motor vehicle seat associated to the headrest; and wherein the control unit is connected with the sensor array, the at least one sensor and the adjusting device, and wherein the control unit includes an evaluation logic which evaluates the signals from the at least one sensor at least as the at least one first signal and the at least one second signal. - View Dependent Claims (17, 18, 19, 20)
