Definitions
- the invention relates to a vehicle seat according to the preamble of patent claim 1. It also relates to a vehicle, in particular a motor vehicle with at least one such vehicle seat.
- the natural frequency of vehicle seats is often in the range of the excitation by the vehicle and leads to discomfort for a passenger sitting on the vehicle seat due to lateral trembling.
- This trembling of the seat is amplified by additional special equipment in the upper backrest area, for example active headrests or screens integrated into the headrest or the upper backrest area, so that the headrests of such vehicle seats perform clearly visible and noticeable lateral vibrations during ferry operation, which affects the quality impression of a vehicle negatively impacted.
- the object of the present invention is to improve a generic vehicle seat in such a way that both the seating comfort increases and the visual quality impression when the vehicle is moving is improved.
- the headrest has a headrest structure provided with a cushion cover and the backrest structure is inserted by means of at least one support rod in an associated support rod receptacle and locked or can be locked there recorded.
- at least one damping element is provided between the backrest structure and the headrest structure.
- the provision of the at least one damping element between the backrest structure and the headrest structure decouples the headrest from the backrest structure in terms of vibrations and dampens vibrations and resonances that occur in the seat backrest in relation to the headrest anchorage in the seat backrest.
- the at least one damping element is preferably formed from an elastic material or has such a material.
- the material is most preferably an elastomer such as rubber (natural or synthetic) or silicone.
- the at least one damping element is provided between the at least one support rod and the associated support rod receptacle.
- the damping element is integrated into the headrest mount in the backrest.
- the damping element extends in the transverse direction of the seat with a first lateral damping section and with a second lateral damping section, starting from the associated at least one support rod towards a respective lateral guide surface formed inside the support rod receptacle, and if the at least one support rod extends in the longitudinal direction of the seat rests essentially without a significant intermediate layer of damping material on the front inner wall area or on the rear inner wall area of the associated support rod receptacle.
- This embodiment enables oscillations and vibrations that occur in the transverse direction of the seat (i.e.
- an insignificant intermediate layer in the above sense can consist, for example, of a skin of the elastic damping material that is only a few, for example one to two tenths of a millimeter thick, and which connects the two lateral damping sections to one another.
- the at least one damping element is provided between the at least one support rod and the headrest structure.
- the at least one damping element is provided inside the headrest.
- the upper end section of the at least one support rod located in the interior of the headrest is provided with an inclined joint of the headrest that has a hinge pin, with a stationary first bearing element being firmly connected to the support rod, and if on the one defining a transverse axis A second bearing element of the headrest structure is mounted on a pivot bolt such that it can be tilted about the transverse axis, the at least one damping element being provided in the transverse direction between the stationary first bearing element and the pivotable second bearing element, preferably surrounding the pivot bolt.
- vibrations and resonances occurring in the transverse direction of the seat are effectively damped without impairing the supporting effect of the headrest attachment in the longitudinal direction of the seat.
- the invention also relates to a vehicle, in particular a motor vehicle, with at least one vehicle seat designed according to the invention.
- FIG. 1 shows a partially sectioned perspective view of a seat backrest of a vehicle seat according to the invention, from the rear at an angle;
- Fig. 2 shows a horizontal section through a headrest mount of a first variant of the invention along the line II-II and
- FIG 3 shows a vertical section through a headrest of a second variant of the invention along the line III-III.
- FIG. 1 shows a perspective rear view of the seat back 10 of a vehicle seat 1 according to the invention of a vehicle (not shown).
- a headrest 12 is attached to the upper end of the seatback 10 by means of two support rods 14, 16 which are connected to a headrest structure 13 inside the headrest 12.
- the support rods 14, 16 are inserted into support rod receptacles 18, 20 assigned to one support rod 14, 16 and are fastened there in a height-adjustable manner (in the Z-direction of the backrest).
- the support rod receptacles 18, 20 are firmly connected to a backrest structure 11 of the seat back, for example welded.
- At least one damping element 22, 24 is arranged between a respective support rod 14, 16 and the support rod receptacle 18, 20 associated therewith.
- the respective damping element 22, 24 extends with a first damping section 22', 24' and with a second damping section 22", 24" starting from the associated support rod 14, 16 towards a respective lateral guide surface 18 formed inside the respective support rod receptacle 18, 20 ', 18" or 20', 20" have a damping effect in the seat transverse direction Y.
- the respective support rod 14 , 16 rests essentially directly on the front and rear inner wall area of the associated support rod receptacle 18 , 20 .
- the elasticity of the respective damping element 22, 24 has a vibration-damping effect in the transverse direction Y of the seat, while in the longitudinal direction X of the seat there is effective and direct support of longitudinal forces occurring in the X-direction from the headrest structure 13 into the backrest structure 11, for example in the event of a frontal collision or a rear-end collision , is guaranteed.
- FIG. 3 shows another variant for damping transverse vibrations, which can be provided alone or together with the variant of FIG. 2 in a vehicle seat according to the invention.
- the respective support rod 14, 16 is firmly connected at its upper end section 14', 16' located inside the headrest 12 to a first bearing element 26', 28' of a tilting joint 26, 28 for tilting the headrest 12 about a transverse axis y.
- Each of the tilting joints 26, 28 has a joint bolt 25, 27, by means of which a second bearing element 26", 28" connected to the headrest structure 13 is mounted so as to be tiltable about the transverse axis y.
- an annular damping element 30, 32 is provided, surrounding the respective pivot pin 25, 27, the in each case on the first bearing element 26', 28' and on the second bearing element 26", 28".
- damping elements 30, 32 also have a vibration-damping effect in the transverse direction Y.
- the device according to the invention can also assume other configurations than those described above.
- the device can here in particular have features that represent a combination of the respective individual features of the claims.
