Support for a headrest, headrest and seat
A support for a headrest may have a single-part bending joint support which may have two support regions. A first support region may be situated in a backrest, and a second support region may be designed to receive a headrest body. Also included is a headrest for a seat, including a vehicle seat, that may have at least one headrest body and a support mentioned above and a seat.
1. A headrest for a vehicle seat, comprising at least one headrest body and a carrier, the carrier comprising a one-piece bending joint carrier, wherein the one-piece bending joint carrier comprises two carrier regions, wherein a first carrier region is arrangeable in a backrest and a second carrier region is configured to receive a headrest body and wherein the one-piece bending joint carrier comprises a plurality of bending joints, which are configured each to perform a predefined angular movement in order to adjust the bending joint carrier in at least two degrees of freedom, wherein the bending joints are each formed by a thinning of material between two adjacent coupling links.
2. The headrest as claimed in claim 1 , wherein the one-piece bending joint carrier is formed from a plurality of coupling links, wherein a bending joint is arranged in each case between two coupling links.
3. The headrest as claimed in claim 1 , wherein the one-piece bending joint carrier is in the form of a multi-bar linkage mechanism.
4. The headrest as claimed in claim 1 , wherein the bending joints are configured to each be adjusted in one degree of freedom.
5. The headrest as claimed in claim 1 , wherein the one-piece bending joint carrier is configured, in a state in which it has been manufactured but not yet formed into the carrier, in the form of a chain of coupling links arranged next to one another, comprising
a terminal coupling link arranged at a first end of the chain,
a terminal coupling link arranged at a second end of the chain,
a central coupling link, and
two intermediate coupling links,
wherein an intermediate coupling link is arranged between the central coupling link and one of the terminal coupling links.
6. The headrest as claimed in claim 5 , wherein the central coupling link is configured, in a state of the bending joint carrier in which it has been formed into the carrier, as a connecting coupling link that connects the carrier regions together.
7. The headrest as claimed in claim 5 , wherein, in the state of the bending joint carrier in which it has been formed into the carrier, the terminal coupling links have been brought together and coupled to one another in an articulated manner in a region of the central coupling link.
8. The headrest as claimed in claim 5 , wherein the terminal coupling links have been coupled to one another in an articulated manner by a fastening element in a region of the central coupling link.
9. The headrest as claimed in claim 8 , wherein the central coupling link has at least one slotted guide, in which the fastening element is held in a movable manner.
10. The headrest as claimed in claim 1 , wherein the one-piece bending joint carrier is a plastics part.
11. The headrest as claimed in claim 1 , wherein the one-piece bending joint carrier is a bent sheet-metal part.
12. A seat, including a vehicle seat, comprising at least:
a backrest, and
a headrest as claimed in claim 1 , held on the backrest,
wherein the first carrier region of the carrier is arranged inside the backrest, and
the second carrier region is arranged outside the backrest.
