Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 shows an exemplary vehicle seat according to the invention in a partially sectioned side view; and

[0017] FIG. 2 is a partially sectioned headrest of a vehicle seat according to FIG. 1.

DETAILED DESCRIPTION OF THE DRAWINGS

[0018] FIG. 1 shows a vehicle seat 1 in a stylized, partially sectioned side view with a seat base element 10 and a backrest 12 which is provided with a headrest 2 on its upper side. The seat base element 10 is connected by means of a seat longitudinal adjustment device 3 to a floor panel 42, which floor panel is part of the vehicle structure 40 of a vehicle 4, in a manner known to a person skilled in the art, for example by screwing. The seat longitudinal adjustment device 3 has a left and a right bottom rail 30 which are connected to the floor panel 42. Each bottom rail 30 is assigned a top rail 32 which is mounted displaceably and lockably with respect to the respective bottom rail 30.

[0019] The headrest 2 has an upper upholstered headrest body 20 which is held on a backrest crossmember 13 of an inner backrest structure 14 of the backrest 12 by way of two laterally spaced-apart support rods 21 of a headrest mount 22. For this purpose, the support rods 21 of the headrest mount 22, of which support rods only one is illustrated in the figures, enter through a respective guide sleeve 15, which is provided on the upper side of the backrest 12 and is connected to the backrest structure 14, into the interior of the backrest 12 and are each accommodated there in a height-adjustable and lockable manner in a tubular receptacle 18, which forms a guide arrangement 17, on the backrest structure 14 of the backrest 12.

[0020] The headrest 2, which is shown in detail in FIG. 2 and is illustrated in partially sectioned form, has, in its interior, a stiff structural element 23 of a headrest structure 24, the structural element 23 being connected rigidly or pivotably to the support rods 21 of the headrest mount 22, and upholstery 26 which surrounds said headrest structure, is composed, for example, of an elastic foam material and is surrounded by a cover 28 made from cloth, leather or synthetic leather.

[0021] A cavity 25 of the upholstery 26, which cavity is provided in front of the structural element 23, contains an electromechanical active element 5 which, in the example shown, is formed by a loudspeaker 50 which, in a manner known per se, has a loudspeaker frame 51 with a loudspeaker basket 52, a loudspeaker diaphragm 53 attached to the latter, and an oscillating coil 54 which is connected to the loudspeaker diaphragm 53 and is designed as a plunger coil and is accommodated in an axially movable manner in a magnetic arrangement 55 connected to the loudspeaker basket 52. The active element 5, i.e. the loudspeaker 50, is fastened to the headrest structure 24 by way of four elastic mount elements 56, 57, of which only the two left ones are illustrated in FIG. 2. The active element 5 which is elastically suspended on the headrest structure 24 by means of said elastic mounting, i.e. the loudspeaker 50 here, forms an oscillating mass which damps externally excited vibrations of the headrest.

[0022] The invention is not limited to the above exemplary embodiment which merely serves for the general explanation of the basic concept of the invention. Rather, the device according to the invention can also adopt different embodiments from those described above within the scope of protection. The device here can have in particular features which represent a combination of the respective individual features of the claims.

[0023] Reference signs in the claims, the description and the drawings serve merely for improved understanding of the invention and are not intended to limit the scope of protection.
