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.
Claims15
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.
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.
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.
