Abstract

A vehicle seat has a vibration absorber. The vehicle seat includes a seat base part and a backrest, which is disposed on the seat base part and is provided with a head restraint. The vibration absorber is disposed in the backrest or in the head restraint and is mounted there on a backrest structure or on a head restraint structure. The vibration absorber has a damper mass, which is supported relative to the backrest structure or to the head restraint structure by way of elastic elements. The spring stiffness of the elastic elements can be adjusted via an actuation mechanism.

First claim

What is claimed is:

1 . A vehicle seat, comprising:
a seat-base part; a seat back arranged on the seat-base part and provided with a headrest; and a vibration absorber arranged in the seat back or in the headrest, the vibration absorber being attached to a backrest structure or to a headrest structure, wherein the vibration-absorber has an absorber mass which is supported via elastic elements, the elastic elements having a spring hardness adjustable via an actuating mechanism, wherein the vibration-absorber comprises a yoke with a first pressure element and with a second pressure element, said first and second pressure elements being relocatable relative to one another along a first direction, and being guided by a guide arrangement, and wherein the elastic elements and the absorber mass are clamped between the first and second pressure elements of the vibration-absorber.

2 . The vehicle seat according to claim 1 , wherein
the actuating mechanism is configured to adjust a compression of the elastic elements based on a setting of the vehicle seat, the setting of the vehicle seat comprising at least one of: an assignment of a seat component to a particular configuration, a seat position, and/or a seat mass.

3 . The vehicle seat according to claim 2 , wherein
the setting of the vehicle seat is an inclination angle of the seat back.

4 . The vehicle seat according to claim 1 , wherein
the actuating mechanism is configured to move the first and second pressure elements toward one another and away from one another along the first direction.

5 . The vehicle seat according to claim 1 , wherein
the elastic elements are or have elastomeric damping bodies.

6 . A vehicle comprising at least one vehicle seat according to claim 1 .

7 . A vehicle seat, comprising:
a seat-base part; a seat back arranged on the seat-base part and provided with a headrest; and a vibration absorber arranged in the seat back or in the headrest, the vibration absorber being attached to a backrest structure or to a headrest structure, wherein the vibration-absorber has an absorber mass which is supported via elastic elements, the elastic elements having a spring hardness adjustable via an actuating mechanism, and the actuating mechanism comprises at least one actuator, wherein a control device is configured to control the at least one actuator and adjustments to the spring hardness of the elastic elements.

8 . The vehicle seat according to claim 7 , wherein
the control device is coupled with at least one sensor for data transmission, which sensor is configured to capture at least one parameter of a setting of the vehicle seat.

9 . The vehicle seat according to claim 8 , comprising:
a characteristic-map storage device in communication with the control device, wherein the characteristic-map storage device stores values for setting the spring hardness of the elastic elements based on the setting of the vehicle seat.

10 . The vehicle seat according to claim 7 , wherein
the actuating mechanism is configured to adjust a compression of the elastic elements based on a setting of the vehicle seat, the setting of the vehicle seat comprising at least one of: an assignment of a seat component to a particular configuration, a seat position, and/or a seat mass.

11 . The vehicle seat according to claim 10 , wherein
the setting of the vehicle seat is an inclination angle of the seat back.

12 . A vehicle comprising at least one vehicle seat according to claim 7 .

13 . A vehicle seat, comprising:
a seat-base part; a seat back arranged on the seat-base part and provided with a headrest; and a vibration absorber arranged in the seat back or in the headrest, the vibration absorber being attached to a backrest structure or to a headrest structure, wherein the vibration-absorber has an absorber mass which is supported via elastic elements, the elastic elements having a spring hardness adjustable via an actuating mechanism, and wherein the elastic elements are or have elastomeric damping bodies, and wherein the actuating mechanism is configured to adjust a compression of the elastic elements based on a setting of the vehicle seat, the setting of the vehicle seat comprising at least one of: an assignment of a seat component to a particular configuration, a seat position, and/or a seat mass.

14 . The vehicle seat according to claim 13 , wherein
the setting of the vehicle seat is an inclination angle of the seat back.

15 . A vehicle comprising at least one vehicle seat according to claim 13 .
