Abstract

A head restraint arrangement with a hinged head restraint (1) is proposed, which is suitable in particular for use with rear seats of vehicles, so that by folding down the head restraint (1) on the one hand it can be ensured that the head restraint (1) is moved from the field of vision of the driver of the vehicle, while on the other hand the head restraint arrangement is configured in such a manner that complete folding down of the rear seat with the head restraint (1) attached to it is possible, since by virtue of a special mechanism (16-23) the head restraint (1), when folding down the rear seat, can fit into an intermediate gap between the rear seat and the corresponding front seat. In order to lock the head restraint in the operating position (a), a locking mechanism (9) is used, which is configured in such a manner that on the one hand it can easily be released by a user and on the other hand secure locking of the head restraint in the operating position (a) is ensured, in order to be able to also restrain large loads, for example in the event of a collision.

Claims

1-26. -26. (canceled)

27. Head restraint arrangement,

having a pivotable head restraint,

having a support on which the head restraint is pivotably attached between an operating position and a non-operating position,

having a locking mechanism coupled with the head restraint, which is configured in such a manner that in a locked state the head restraint is held in the operating position and in an unlocked state the head restraint is released for movement to the non-operating position, and

having an actuation device for releasing the locking mechanism,

wherein the support is pivotably mounted relative to a horizontal plane so that the support with the head restraint can be folded down,

connecting means are coupled to the head restraint and to the support, and

the connecting means are configured in such a manner that when folding down the support with the head restraint attached to it, the head restraint is held in the non-operating position at a preset angle relative to the support.

28. Head restraint arrangement according to claim 27, wherein the locking mechanism is configured in such a manner that when the head restraint is moved to the operating position the locking mechanism is brought independently into the locked state and thus the head restraint is held in the operating position.

29. Head restraint arrangement according to claim 27, wherein the locking mechanism comprises a latch with an opening in combination with a locking pin, whereby in the locked state the locking pin engages the opening of the latch, while when the actuation device is manipulated the locking pin is moved from the opening of the latch.

30. Head restraint arrangement according to claim 29, wherein the locking mechanism is configured in such a manner that in the unlocked state the locking pin is held against a force of sprung-mounted means, whereby when the head restraint is moved to the operating position the retention of the locking pin is released, so that through the force of the sprung-mounted means the locking pin engages the opening of the latch, while when the actuation device is manipulated the locking pin is again moved from the opening of the latch and held against the force of the sprung-mounted means.

31. Head restraint arrangement according to claim 29, wherein the latch is coupled with the head restraint and the locking pin with the support.

32. Head restraint arrangement according to claim 27, wherein the head restraint is attached to a cylinder, which is rotatably mounted in relation to the support.

33. Head restraint arrangement according to claim 27, wherein sprung-mounted means are provided, in order when the actuation device is manipulated to move the head restraint automatically from the operating position to the non-operating position.

34. Head restraint arrangement according to claim 33, wherein the sprung-mounted means comprise springs, which on the one hand are coupled with the head restraint and on the other hand with the support.

35. Head restraint arrangement according to claim 33, wherein the springs on the one hand are coupled with the cylinder and on the other hand with the support.

36. Head restraint arrangement according to claim 27, wherein damping means are provided, in order to dampen movement of the head restraint from the operating position to the non-operating position.

37. Head restraint arrangement according to claim 36, wherein the damping means on the one hand are coupled with the head restraint and on the other hand with the support.

38. Head restraint arrangement according to claim 36, wherein the damping means on the one hand are coupled with the cylinder and on the other hand with the support.

39. Head restraint arrangement according to claim 27, wherein the actuation device comprises a pressure mechanism.

40. Head restraint arrangement according to claim 27, wherein limitation means are provided, in order when the actuation device is manipulated to limit movement of the head restraint to the non-operating position, whereby the limitation means are configured in such a manner that the head restraint in the non-operating position encloses a pre-defined angle in relation to the support.

41. Head restraint arrangement according to claim 27, wherein the head restraint is attached to a cylinder, rotatably mounted on the support,

wherein the cylinder exhibits at least one projection protruding from its surface, which engages at least one recess formed in the circumferential direction of the cylinder and is mounted therein, whereby a longitudinal end of the recess forms a stop for the corresponding projection of the cylinder and limits rotation of the cylinder with the head restraint attached to it.

42. Head restraint arrangement according to claim 41, wherein the at least one recess is provided in a corresponding ring, which is formed in the circumferential direction of the cylinder and which surrounds the cylinder.

43. Head restraint arrangement according to claim 42, wherein the ring is mounted flexibly relative to the cylinder.

44. Head restraint arrangement according to claim 42, wherein the ring is held in position relative to the cylinder via connecting means, which are coupled with the support.

45. Head restraint arrangement according to claim 44, wherein the connecting means comprise at least one Bowden cable arrangement coupled on the one hand with a ring and on the other hand with a pivot spindle of the support.

46. Head restraint arrangement according to claim 45, wherein the connecting means comprise a connection between the at least one ring and the support.

47. Head restraint arrangement according to claim 27, wherein the head restraint arrangement is configured in such a manner that the head restraint is folded away forward in the non-operating position relative to the support.

50. Seat with a head restraint arrangement according to claim 27.

51. Seat according to claim 50, wherein the seat is a rear seat of a vehicle.

48. Head restraint arrangement,

having a pivotable head restraint,

having a support on which the head restraint is pivotably attached between an operating position and a non-operating position,

having a locking mechanism coupled with the head restraint, which is configured in such a manner that in a locked state the head restraint is held in the operating position and in an unlocked state the head restraint is released for movement to the non-operating position, and

having an actuation device for releasing the locking mechanism,

wherein the locking mechanism comprises a latch with an opening in combination with a locking pin, whereby in the locked state the locking pin engages the opening of the latch, while when the actuation device is actuated the locking pin is moved from the opening of the latch.

49. Head restraint arrangement,

having a pivotable head restraint,

having a support on which the head restraint is pivotably attached between an operating position and a non-operating position,

having a locking mechanism coupled with the head restraint, which is configured in such a manner that in a locked state the head restraint is held in the operating position and in an unlocked state the head restraint is released for movement to the non-operating position, and

having an actuation device for releasing the locking mechanism,

wherein damping means are provided, in order to dampen movement of the head restraint from the operating position to the non-operating position.

52. Seat according to claim 49, wherein a back rest of the seat comprises a frame as the support for the head restraint.
