Abstract

A head restraint for a seat back of a vehicle seat may have two lateral wings. A topmost surface of the wings may flare from top to bottom in a driving position.

Claims

1-13. (canceled)

14. A head restraint for a seat back of a vehicle seat, comprising: two lateral wings, wherein in a driving position, an upper surface of the wings runs with an increasing projection from top to bottom.

15. The head restraint as claimed in claim 14, further comprising a number of reading lights.

16. The head restraint as claimed in claim 15, wherein the reading lights are integrated in the lateral wings.

17. The head restraint as claimed in claim 16, wherein the reading lights are integrated in the bottom side of the lateral wings.

18. The head restraint as claimed in claim 14, further comprising a number of loudspeakers and/or a number of microphones.

19. The head restraint as claimed in claim 18, wherein the loudspeakers and/or the microphones are integrated in the lateral wings.

20. The head restraint as claimed in claim 19, wherein the loudspeakers and/or the microphones are integrated in the bottom side of the lateral wings.

21. A vehicle seat, comprising: a seat back, and a head restraint comprising two lateral wings, wherein in a driving position, an upper surface of the wings runs with an increasing projection from top to bottom.

22. The vehicle seat as claimed in claim 21, further comprising a connecting element for connecting the head restraint to the seat back, wherein the connecting element is at least part of an adjustment mechanism and wherein the connecting element is displaceable with respect to the seat back in the z direction and pivotable about a horizontal axis.

23. The vehicle seat as claimed in claim 21, wherein the head restraint is linearly displaceable with respect to the connecting element at least in part in an x direction.

24. The vehicle seat as claimed in claim 23, wherein the displacement in the z direction, the rotation and the displacement in the x direction are performable simultaneously.

25. The vehicle seat as claimed in claim 21, further comprising a rotatability about a vertical axis.

26. The vehicle seat as claimed in claim 23, wherein the displaceability in the z direction amounts to between 60 mm and 80 mm; and/or the rotatability about the horizontal axis amounts to between 5 and 9; and/or the displaceability in the x direction amounts to between 20 mm and 40 mm.

Description

[0023] The exemplary embodiments of the inventions are explained in more detail with reference to the drawings, in which:

[0024] FIG. 1 shows an embodiment of a head restraint according to the invention in a perspective view,

[0025] FIG. 2 shows an associated further perspective view,

[0026] FIG. 3 shows an associated further perspective view, and

[0027] FIGS. 4a to 4c show associated further perspective views.

[0028] Mutually corresponding parts are provided with identical reference signs in all of the figures.

[0029] FIGS. 1 to 3 and 4a, 4b and 4c show a head restraint 1 according to the invention. The head restraint 1 has a shape that satisfies the needs to be expected concerning seating comfort in autonomously driving vehicles. The shape of the lateral wings 1.1 is configured such that it is possible to laterally support a head of a person. These lateral wings 1.1 of the head restraint 1 are shaped such that it is indeed made possible to laterally support the head, but a peripheral vision of the person is not impaired, in particular when the person is driving the vehicle in which the head restraint is arranged.

[0030] The head restraint 1 for the seat back 3 of the vehicle seat has two lateral, that is to say laterally projecting, wings 1.1. Here, an upper surface 1.1.1 of the wings 1.1 runs from top to bottom as it increasingly projects in a driving position, that is to say in an upright position of the head restraint 1 and thus in an upright position of the seat back 3. The surface 1.1.1 of the wings 1.1 thus slopes from the inside to the outside, specifically less strongly in a top region, that is to say in the region of relatively small projection, than in a bottom region, that is to say in the region of relatively great projection.

[0031] Two reading lights 1.2 and a loudspeaker system with two loudspeakers 1.3 are integrated in the head restraint 1. The reading lights 1.2, the loudspeakers 1.3 of the loudspeaker system and an optional microphone are always perfectly positioned in this case, in particular independently of a position of the head restraint 1 with respect to the seat back 3 of the vehicle seat and independently of a position of the vehicle seat in the vehicle, for example even in the case of a deeply folded-down seat back 3 or in the case of a vehicle seat rotated by 180 about the vertical axis. The head restraint 1 allows for an improvement of an adjustment range in order to make it possible to support the head of the person, even in a deeply reclined position. At the same time, the requirements resulting from spatial restrictions are taken into account by virtue of the fact that a slender adjustment mechanism is used, which is arranged at least in part in a connecting element 2.

[0032] A reading light 1.2 and a loudspeaker 1.3 are arranged in a common unit in each lateral wing 1.1.

[0033] An adjustment, shown in FIGS. 4a and 4b, of the head restraint 1 in the x direction is made possible by an, in particular electrically driven, adjustment of the head restraint 1, an adjustment in the x direction by 30 mm by way of turning the head restraint by 7 being combinable with an additional displacement by 30 mm in the x direction as a linear displacement.

[0034] An adjustment mechanism, illustrated in FIG. 4c, for an adjustment of the head restraint 1 in the z direction uses a space in the top region of the seat back 3 to which the head restraint 1 is assigned. The arrangement of the adjustment mechanism for the adjustment in the z direction in the top region of the seat back 3 allows a greater freedom of design, in particular a so-called spine design instead of two simple conventional rods, the appearance of which could be regarded as outdated. The head restraint is adjustable in height, that is to say in the z direction, by 70 mm.
