wherein the left and right sides of the core are provided with respective ear parts protruding outward in the left and right directions, respectively, such that each ear part is rotatable around an axis extending in the left-right direction.
9. The headrest as claimed in claim 1 , comprising a skin material covering the core and the devices, and one or more pad members located between the skin material and the core.
10. A vehicle seat, comprising the headrest claimed in claim 1 .
11. The headrest as claimed in claim 1 , wherein the receiving recesses are provided on the left and right of the front surface of the core front portion, one on each side, and
wherein the core front portion and the core rear portion define a cavity.
12. The headrest as claimed in claim 11 , wherein a through hole leading to an interior of the cavity is provided on a bottom wall defining the receiving recesses.
13. The headrest as claimed in claim 1 , wherein the core rear portion is provided with a rear side recess that is recessed rearward.
14. The headrest as claimed in claim 13 , wherein a partition wall is provided at the center of the rear side recess in the left-right direction to separate the rear side recess into left and right parts.
15. The headrest as claimed in claim 13 , wherein the rear side recess is provided with one or more connecting parts for connecting to the core front portion.
16. The headrest as claimed in claim 13 , wherein a partition wall is provided at the center of the rear side recess in the left-right direction to separate the rear side recess into left and right parts,
wherein the rear side recess is provided with a plurality of connecting parts for connecting to the core front portion, and
wherein the connecting parts are arranged symmetrically with respect to the partition wall.
17. The headrest as claimed in claim 13 , wherein one or more ribs are provided at a bottom surface of the rear side recess.
18. A headrest, comprising:
a box-shaped core having one or more receiving recesses which are recessed inward from an outer surface thereof; and
one or more devices configured to be received in the respective receiving recesses;
wherein the core is composed of a box-shaped core front portion and a box-shaped core rear portion positioned behind the core front portion,
wherein the core front portion and the core rear portion are separate entities,
wherein the core rear portion is provided with a rear side recess that is recessed rearward, wherein a partition wall is provided at the center of the rear side recess in the left-right direction to separate the rear side recess into left and right parts,
wherein the rear side recess is provided with a plurality of connecting parts for connecting to the core front portion, and
wherein the connecting parts are arranged symmetrically with respect to the partition wall.
19. A headrest, comprising:
a box-shaped core having one or more receiving recesses which are recessed inward from an outer surface thereof; and
one or more devices configured to be received in the respective receiving recesses;
wherein the core is composed of a box-shaped core front portion and a box-shaped core rear portion positioned behind the core front portion,
wherein the core front portion and the core rear portion are separate entities,
wherein each device is provided with a device-side connector at a rear end surface,
wherein a bottom wall of each receiving recess is provided with a body-side connector configured to be connectable to the device-side connector when the device is accommodated in the receiving recess, and
