First claim

The invention claimed is:

1. A vehicle seat, comprising:
a seat bottom;
a backrest which is attached to the seat bottom and has a backrest structure;
a headrest attached to the backrest, the headrest having a headrest structure provided with an upholstery cover;
at least one support rod for the headrest, the at least one support rod being inserted in an associated support rod holder of the backrest structure and being locked or lockable therein;
at least one damping element provided between the backrest structure and the headrest structure, the damping element being formed from an elastic material or comprising the elastic material, wherein
the at least one damping element is provided with a damping action between the at least one support rod and the associated support rod holder in a transverse direction of the vehicle seat;
the at least one damping element extends in the transverse direction so as to provide a damping action with a first damping portion and with a second damping portion, starting from the associated at least one support rod to one respective lateral guide surface which is configured in an interior of the support rod holder, and
the at least one support rod bears against a front inner wall region or against a rear inner wall region of the associated support rod holder substantially without a significant interposition of damping material in a seat longitudinal direction.

2. The vehicle seat according to claim 1 , wherein:
an upper end portion of the at least one support rod, which is respectively located in an interior of the headrest, is provided with a tilting joint of the headrest which has a hinge bolt, wherein a fixed first bearing element is fixedly connected to the associated support rod,
a second bearing element of the headrest structure is mounted on the respective hinge bolt, which determines a transverse axis, so as to be tiltable about the transverse axis, and
the at least one damping element is formed from an elastic material or comprises the elastic material and is provided with a damping action in the transverse direction between the fixed first bearing element and the pivotable second bearing element.

3. The vehicle seat according to claim 2 , wherein
the at least one damping element surrounds the associated hinge bolt.

4. A vehicle comprising at least one vehicle seat according to claim 1 .
