Head restraint for a vehicle seat, and vehicle seat
A head restraint for a vehicle seat may have a head restraint support, a first loudspeaker unit, and at least one second loudspeaker unit. The head restraint may also have a lining element and a cover. The lining element covers the head restraint support, the first loudspeaker unit and the at least one second loudspeaker unit in the direction of a contact surface. The cover covers the head restraint support, the first loudspeaker unit and the at least one second loudspeaker unit in a direction opposite to the contact surface. The lining element, the head restraint support and the cover are designed in such a way that a sound generated by the first loudspeaker unit can be emitted from the head restraint to an external environment of the head restraint in a largely unattenuated manner. A vehicle seat having a backrest and the head restraint is also provided.
1. A headrest for a vehicle seat, comprising:
a headrest carrier,
a first loudspeaker unit and at least one second loudspeaker unit, wherein the first loudspeaker unit and the at least one second loudspeaker unit are carried by the headrest carrier, the headrest further having a trim element and a cover,
wherein the trim element covers the headrest carrier, the first loudspeaker unit and the at least one second loudspeaker unit in the direction of an abutment face, and the cover covers the headrest carrier, the first loudspeaker unit and the at least one second loudspeaker unit in a direction counter to the abutment face,
wherein the trim element, the headrest carrier and the cover are configured in such a manner that a sound, which is generated by the first loudspeaker unit, can be output from the headrest to an external environment of the headrest in a substantially non-damped manner.
2. The headrest as claimed in claim 1 , wherein the specific air flow resistance of the trim element is less than 200 Pa s/m.
3. The headrest as claimed in claim 1 , wherein the specific air flow resistance of the cover is less than 200 Pa s/m.
4. The headrest as claimed in claim 1 , wherein the headrest carrier has the abutment face which is provided with a plurality of internal, flexible support elements formed thereby.
5. The headrest as claimed in claim 4 , wherein the specific air flow resistance of the abutment face is less than 200 Pa s/m.
6. The headrest as claimed in claim 1 , wherein the trim element has a perforation in a region which covers the first loudspeaker unit, the at least one second loudspeaker unit and the abutment face.
7. The headrest as claimed in claim 1 , wherein the headrest carrier and the trim element have a perforation in a region which laterally covers the at least one second loudspeaker unit.
8. The headrest as claimed in claim 1 , wherein the cover has a perforation in a region which covers the first loudspeaker unit in a direction counter to the abutment face.
9. The headrest as claimed in claim 1 , wherein the trim element has a trim material and a foam layer.
10. The headrest as claimed in claim 9 , wherein the foam layer is stitched to the trim material.
11. The headrest as claimed in claim 9 , wherein the foam layer has a thickness of up to 20 mm.
12. The headrest as claimed in claim 9 , wherein the foam layer is a layer of acoustic foam.
13. The headrest as claimed in claim 1 , wherein at least one sound wave guide is arranged between the first loudspeaker unit and the at least one second loudspeaker unit.
14. The headrest as claimed in claim 13 , wherein the sound wave guide is integrated in the headrest carrier.
15. A vehicle seat having a backrest having the headrest as claimed in claim 1 .
