Description

TECHNICAL FIELD

[0001] The invention relates to a vehicle seat. The invention also relates to a vehicle, in particular a motor vehicle, having at least one such vehicle seat. BACKGROUND

[0002] The natural frequency of a vehicle seat is usually in the range of the driving frequency of the vehicle and leads to an uncomfortable feeling for the occupant sitting on the vehicle seat due to lateral oscillations. This oscillation of the seat is enhanced by additional special equipment in the upper backrest area, for example by an active headrest or by a screen integrated into or on the backrest area, so that the headrest of such a vehicle seat performs a visibly and perceptibly lateral vibration in the driving operation, which adversely affects the quality impression of the vehicle.

[0003] The vibrations occurring in the seat backrest are usually reduced by complex and expensive dampers arranged inside the seat backrest. SUMMARY

[0004] It is the task of the invention to improve a vehicle seat of the same type such that both the seat comfort and the visual quality impression are improved when the vehicle is driving.

[0005] In a vehicle seat having a seat lower part, a seat backrest with a backrest structure mounted on the seat lower part and a headrest mounted on the seat backrest, the headrest having a headrest structure provided with a cushioning sleeve and being inserted in a provided support rod receptacle of the backrest structure by means of at least one support rod and being received there locked or lockable, it is provided according to the invention that at least one damping element is arranged between the backrest structure and the headrest structure.

[0006] Advantages

[0007] The arrangement of the at least one damping element between the backrest structure and the headrest structure decouples the headrest from the backrest structure in vibration technology and damps the vibrations and resonances occurring in the seat backrest relative to the headrest anchor in the seat backrest.

[0008] Preferably, the at least one damping element is composed of or has an elastic material. This material is particularly preferably an elastomer, for example (natural or synthetic) rubber or silicone.

[0009] According to a first variant of the invention, which can be combined with other variants, the at least one damping element is arranged between the at least one support rod and the provided support rod receptacle. Here, the damping element is integrated into the headrest receptacle in the seat backrest.

[0010] It is advantageous here that the damping element extends in the seat transverse direction with a lateral first damping section and a lateral second damping section from the assigned at least one support rod respectively towards a lateral guide surface configured in the interior of the support rod receptacle, and that the at least one support rod rests on a front inner wall region or a rear inner wall region of the assigned support rod receptacle in the seat longitudinal direction substantially without a main intermediate layer composed of damping material. This embodiment enables damping of vibrations and oscillations occurring in the seat transverse direction, i.e. in the vehicle transverse direction, without impairing the direct support of the at least one support rod in the assigned support rod receptacle in the seat longitudinal direction, i.e. in the vehicle longitudinal direction, as required in the event of a vehicle collision. The non-main intermediate layer may, for example, consist in the above-mentioned sense of a few, for example one to two tenths of a millimeter thick skin of elastic damping material, which connects the two lateral damping sections to one another.

[0011] In another embodiment of the application, the at least one damping element is arranged between the at least one support rod and the headrest structure. In a second variant of the application, which can also be combined with the first variant, the at least one damping element is arranged in the interior of the headrest.

[0012] It is advantageous here that the upper end section of the at least one support rod respectively located in the interior of the headrest is provided with a tilt hinge of the headrest having a hinge pin, wherein a fixed first support element is fixedly connected with the support rod and a second support element of the headrest structure is tiltably supported about a transverse axis on the hinge pin determining the transverse axis, wherein the at least one damping element is arranged in the transverse direction between the fixed first support element and the pivotable second support element, preferably around the hinge pin. In this variant, vibrations and oscillations occurring in the seat transverse direction are also effectively damped without impairing the support of the headrest fixture in the seat longitudinal direction.

[0013] Finally, the application also relates to a vehicle, in particular a motor vehicle, having at least one vehicle seat configured according to the application. BRIEF DESCRIPTION OF DRAWINGS

[0014] The preferred embodiments of the application with additional design details and further advantages are described and explained in detail below with reference to the drawings.

[0015] The drawings show:

[0017] Figure 2a horizontal section along line II-II of a headrest receptacle of a first variant of the application, and

[0018] Figure 3 a longitudinal section along line III-III of a headrest of a second variant of the application. DETAILED DESCRIPTION

[0019] Figure 1 A seat back 10 of a vehicle seat 1 according to the application of a vehicle (not shown) is shown in a perspective rear view. A headrest 12 is mounted on the upper end of the seat back 10 by means of two support rods 14, 16 which are connected with a headrest structure 13 inside the headrest 12. The support rods 14, 16 are inserted into support rod receptacles 18, 20 which are assigned to the support rods 14, 16, respectively, and are fixed there (in the Z direction of the backrest) height-adjustably. The support rod receptacles 18, 20 are fixedly connected, for example welded, with a backrest structure 11 of the seat back.

[0020] As can be seen in Figure 2 At least one damping element 22, 24 is arranged between each support rod 14, 16 and the support rod receptacle 18, 20 assigned thereto. The respective damping element 22, 24 extends in the seat transverse direction Y effectively dampeningly from the assigned support rod 14, 16 towards a lateral guide face 18', 18" or 20', 20" which is constructed in the interior of the respective support rod receptacle 18, 20 in a first damping section 22', 24' and in a second damping section 22", 24". In the seat longitudinal direction X, the respective support rod 14, 16 rests essentially directly against the front and rear inner wall regions of the assigned support rod receptacle 18, 20. In this way, the elasticity of the respective damping element 22, 24 acts in the seat transverse direction Y as a damper, while in the seat longitudinal direction X it ensures an effective and direct support of longitudinal forces occurring in the X direction, for example in a frontal collision or in a rear collision, from the headrest structure 13 into the backrest structure 11.

[0021] Figure 3 Another variant for damping lateral vibrations is shown, which can be used alone or in combination with the Figure 2Variants of the above-described embodiments are provided in a vehicle seat according to the application. The respective support rods 14, 16 are fixedly connected at their upper end sections 14', 16' inside the headrest 12 to first support elements 26', 28' of a tilting hinge 26, 28 for tilting the headrest 12 about the transverse axis y. Each tilting hinge 26, 28 has a hinge pin 25, 27 by means of which a second support element 26", 28" connected to the headrest structure 13 can be supported in a tiltable manner about the transverse axis y. Between the first support elements 26', 28' mounted on the respective support rods 14, 16 and the assigned pivotable second support elements 26", 28" connected to the headrest structure 13, there is respectively provided an annular damping element 30, 32 which is respectively applied against the first support element 26', 28' and against the second support element 26", 28" about the respective hinge pin 25, 27. These damping elements 30, 32 also act as dampers in the transverse direction Y.

[0022] The application is not limited to the above-described embodiments, which serve merely to illustrate the core idea of the application in general terms. The device according to the application can also take other design forms than those described above within the scope of protection. Here, the device can in particular have the features which are combinations of the respective individual features of the claims.

[0023] The claims, the specification and the drawing figures are merely intended to better understand the application and should not limit the scope of protection.
