Definitions
- the invention relates to a headrest for a vehicle seat according to the preamble of patent claim 1.
- the invention also relates to a motor vehicle with a vehicle seat and headrest according to patent claim 10.
- a vehicle seat for a motor vehicle which can be designed in particular as a passenger car, often has a headrest which is usually adjustably attached to a backrest of the vehicle seat.
- the headrest serves to support a head of a vehicle occupant, ie an occupant's head.
- the headrest allows the occupant to assume a particularly comfortable position in the vehicle and also reduces the risk of injury, for example to the neck of the occupant, in the event of an impact by supporting the head.
- actuator-driven neck supports in the form of a drawer are known from the prior art.
- Disadvantages of the prior art are a lack of comfort when operating and/or using the neck support and a possible risk of injury from protruding neck supports.
- a first aspect of the invention relates to a headrest.
- the headrest according to the invention for a vehicle seat includes a padded support surface, which is used to support an occupant's head.
- the vehicle seat is in particular a motor vehicle seat for a motor vehicle, which is designed as a passenger car, for example.
- the headrest is advantageously held in a height-adjustable manner on a backrest of the vehicle seat.
- the support surface is padded, for which purpose the headrest advantageously has a pad.
- the occupant's head is the head of an occupant or user of the motor vehicle, which can support the head on the support surface, for example to relax.
- the vehicle seat In an intended position or usage position of the vehicle seat and thus the headrest in the motor vehicle, the vehicle seat is oriented so that the occupant is sitting in the vehicle and the backrest is not folded back to lie down.
- the support surface In this intended position, the support surface is oriented essentially vertically, so that in particular a back of the occupant's head can be supported on the support surface, for example against acceleration forces of the motor vehicle along the vehicle longitudinal direction.
- the headrest includes a neckrest.
- the invention provides that the neck support is designed to be pivotable between a flat position and an angular position by means of at least one friction hinge, with one end region of the neck support forming part of the support surface in the flat position and in the angular position, the end area of the neck support is at an angle to the support surface and is adjacent to it.
- the end area is in particular at an angle to the support surface in such a way that the end area points in the direction of a neck when the vehicle occupant is sitting on the vehicle seat as intended. Due to the adjoining of the end area to the supporting surface, in particular now reduced, in the angular position, the end area can transition, in particular seamlessly, into the supporting surface.
- the end area serves as part of the support surface, in particular for supporting the occupant's head.
- the angled position is made possible by the angled protruding end of the neck support that the end advantageous to Supporting a connected to the occupant's head neck area or neck and / or shoulder area of the occupant is formed.
- the end area of the neckrest in the surface position is the lower area of the support surface. In the angular position, the end area thus borders the support surface at the bottom.
- the end area of the neck support can also be referred to as a folding wing and overall forms a folding wing of the headrest.
- the friction hinge is a mechanical component which is used to move the neck support between the angular position and the surface position using external torque and to hold the neck support independently in the respective position or in an intermediate position in the respective position.
- the functional principle of the friction hinge which can also be referred to as a torque hinge, is based on friction.
- a breakaway torque and/or a moment of movement can correspond to a dynamic moment, which allows the occupant or the user to move the neck support comfortably and without jerking.
- the pivoting can take place in particular into or out of the angular position by the occupant manually pulling it forward, for example at the end region.
- the headrest with the neckrest in the surface position looks like an ordinary headrest.
- the headrest and thus the vehicle seat can be designed particularly elegantly, for example.
- the lower area of a headrest cushion is designed to be pivotable via a friction hinge, with no optical change compared to the known prior art being recognizable when folded back. Pivoting or forward pivoting can be done by manually pulling a lower edge of the padding forward. The dimensional stability in the respective position is achieved through the resistance of the friction hinge.
- the invention thus results in the advantage that, in addition to good head support, adequate and in particular individually adjustable neck support is made possible for a vehicle occupant.
- the vehicle seat can be a front seat or a seat in the rear of the vehicle.
- the advantage of the invention is that the external geometry of the headrest is visually the same and the headrest can therefore also be used For example, when adjusting the height relative to a backrest of the vehicle seat, there is no restriction compared to an ordinary headrest.
- the headrest according to the invention offers an additional function and acts as a comfortable and effective neck support for the vehicle occupant.
- a particularly simple technical solution to the adjustability or pivotability of the neck support can be implemented by using the friction hinge.
- the neck support is in functional use in its respective position, ie both in the flat position and in the angular position.
- the neck support has a use position and a non-use position, with no function being achieved in the latter.
- the use of the friction hinge has the advantage that in the event of an accident, for example due to an impact event on the motor vehicle, an extended neck support can fall or move independently from the angular position back into the surface position due to the force.
- the headrest can be used just as safely as an ordinary headrest.
- a resistance of the friction hinge is adapted to the impact event, as a result of which the neck support pivots independently into the flat position in the event of an impact event.
- the resistance, in particular the frictional resistance of the friction hinge in the event of an accident, results in the neck support returning automatically, for example due to centrifugal forces and/or other forces.
- the neck support comprises a frame element which forms a contour of the end area.
- an outer shape of the end area of the neck support and in the surface position thus an outer shape of the support surface is formed by a frame or the frame element.
- the shape of the end area of the neck support used to support the neck is thus formed by the frame element.
- the frame element is advantageously covered with a cushion or a cushion element. This results in the advantage that the shape of the end region can be formed in a particularly simple manner; for this purpose, the frame can be connected in a rotationally fixed manner to part of the friction hinge, whereby the frame element is particularly advantageous when the occupant pivots the neck support as a handle or handle element can be used.
- the headrest includes a massage device.
- the massage device of the headrest or the neckrest can, for example, cause a massage effect on the head or neck and/or shoulder area of the occupant via a mechanical movement.
- the headrest can thus advantageously be used particularly comfortably by the occupant, as a result of which, for example, a journey by motor vehicle can be made particularly pleasant.
- the massage device has a vibration element.
- the vibration element is, for example, a motor with a shaft on which an unbalanced weight is arranged.
- the vibration element has the advantage that the massage device can be designed in a particularly simple and thus, for example, inexpensive manner.
- the massage device has a pneumatic actuator.
- the pneumatic actuator operates, for example, an actuator which provides for a deformation of at least a partial area of the neck support, in particular a partial area of the end area. This can cause a massage effect on the occupant.
- the advantage of the pneumatic actuator is that the massage can be carried out particularly intensively and/or particularly precisely.
- the massage device is arranged on the neck support, and there in particular on the end area and very particularly on the frame element.
- the area of the headrest that is used to support the neck has a device for massaging the vehicle occupant.
- the arrangement of the massage device on the neck support and in particular on the end area makes it possible for the massage effect to be applied quasi on an edge or the lower end of the head or neck support.
- the massage effect can extend to the lower neck or upper shoulder area of the occupant, as a result of which the occupant can particularly relax.
- the headrest has a removable cushion element which can be fixed to the support surface by means of a fastening element.
- a cushion element which can be particularly soft and/or cuddly, for example to allow the occupant's head to sink particularly well into the cushion element, so that the cushion element can also be referred to as a cuddly cushion.
- the fastening element can in particular be designed in such a way that the cushion element can be adapted relative to the support surface, for example to a size of the occupant.
- the position of the cushion element can be influenced by pivoting the neck support. This results in the advantage that the use of the headrest is particularly comfortable for the occupant and the effectiveness of the neck support can be increased.
- the cushion element comprises a heating element.
- the cushion element has a heater, which can increase the temperature of at least part of the cushion element compared to, for example, an ambient temperature.
- the heating element can also be designed in such a way that it is not used, or not only for heating, but also for cooling.
- the heating element can also be designed as a temperature control element.
- a second aspect of the invention relates to a motor vehicle, in particular a passenger car, with a vehicle seat which has a headrest according to the invention.
- the vehicle includes a vehicle seat, which in particular has a backrest.
- the headrest is advantageously held on this.
- the headrest of the vehicle seat is provided with a headrest cushion, for example, which is designed to be pivotable via a friction hinge.
- a headrest cushion for example, which is designed to be pivotable via a friction hinge.
- advantages and advantageous configurations of the first aspect are to be regarded as advantages and advantageous configurations of the second aspect of the invention and vice versa.
- FIG. 1 shows a schematic perspective view of a headrest with a neckrest, the end area of which is pivoted into an angular position
- FIG. 2 shows the headrest according to FIG. 1 in a schematic perspective view, with the end region being pivoted into a flat position;
- FIG. 3 shows a schematic perspective view of the headrest with the end area in the angular position without padding
- FIG. 4 shows a schematic perspective view of the headrest without upholstery with the end area in the flat position
- FIG. 5 shows a schematic perspective view of the headrest with side paneling and end area in the flat position
- FIG. 6 shows a schematic perspective view of the headrest according to FIG. 5 in the angular position.
- Fig. 1 shows a schematic perspective view of a headrest 10 for a vehicle seat 11 of a motor vehicle, not shown, in particular a passenger car.
- the vehicle seat 11 has a headrest 10 for supporting an occupant's head 12 of a vehicle occupant.
- the headrest 10 is attached to a backrest 14 of the vehicle seat 11 .
- Headrests 10, which offer a special comfort function, also have a neck support 16. So that the headrest 10 can support the occupant's head 12 particularly advantageously, the headrest 10 has a support surface 18 which is padded.
- a cushion 20 is provided for this purpose, for example.
- the neckrest 16 is between a flat position shown in FIG. 2 and an angular position shown here in FIG at least one friction hinge 22 shown in FIGS. 3 and 4 is pivotable.
- an end region 24 of the neck restraint 16 is part of the support surface 18.
- the end region 24 of the neck restraint 16 is positioned at an angle to the support surface 18, with the end region 24 being designed to support a neck region 26 or neck connected to the occupant's head 12 is.
- the end region 24 is essentially at the lower end of the headrest 10.
- the headrest 10 has the advantage that the neckrest 16 does not have to be pivoted into a non-use position unnecessarily if the neck is to be supported is currently not desirable, since it takes over the function of the support surface 18 in the surface position and thus serves as a support for the occupant's head 12 instead of the neck support.
- a resistance of the friction hinge 22 is advantageously adapted to an impact event, that is to say in particular to the acceleration which can act on the motor vehicle or the headrest 10 or the neckrest 16 .
- the neck support 16 can pivot independently into the flat position.
- the motor vehicle shown and the headrest 10 shown each result in the advantage that the use of the friction hinge 22 makes it possible to provide a particularly simple technical solution for pivoting the neckrest 16 .
- Due to the design of the friction hinge 22 and the tuning of its resistance, in particular the frictional resistance, when it is actuated the headrest 10 can be operated particularly easily, for example with one hand of the occupant, and the neckrest 16 can thus be pivoted.
- the neckrest in the event of an impact, for example in the event of an accident, the neckrest can be automatically reset to the flat position, which means that the headrest 10 shown can be operated safely.
- the headrest 10 can be used both for a vehicle seat 11 in the front area and for a vehicle seat 11 in the rear area of the motor vehicle.
- the headrest 10 can be connected to the backrest 14 by means of fixing elements 30 and via these in a height-adjustable manner.
- the structure of the headrest 10 can include a base element 36 or a base body, to which, for example, the friction hinge 22 and/or the cushion 20 are attached, among other things.
- a removable cushion element 28 is advantageously provided, which can be fixed to the support surface 18 by means of a fastening element (not shown). Additionally, the cushion member 28 may include a heating element 42 that may be used to heat and/or cool the cushion member 28 and thus warm and/or cool the occupant's head 12 and neck region 26, respectively.
- cushion element 28 with end region 24 when pivoting neck support 16 allows heating element 42 to be positioned particularly advantageously on neck region 26 of the vehicle occupant, as a result of which heat can be introduced into neck region 26 and/or shoulder region of the vehicle occupant in a particularly advantageous manner , whereby the headrest 10 can be used particularly comfortably.
- the headrest 10 can have a massage device 32 which can include both a vibration element and/or a pneumatic actuator in order to achieve a massage effect for the vehicle occupant.
- the massage device 32 is in particular on the neck support 16 and there on the End area 24 is arranged, whereby the massage device 32 can be positioned particularly advantageously on the neck area 26 of the vehicle occupant, since a massage there can usually lead to more relaxation than directly on the occupant's head 12.
- FIG. 2 also shows the headrest 10 according to FIG. 1 in a schematic perspective view, in which, in contrast to FIG.
- FIG. 3 and 4 also show the headrest 10 in a schematic perspective view, now with the cushion 20 removed, as a result of which the friction hinge 22 can be seen particularly well.
- 3 shows the neck support 16 in the angular position
- FIG. 4 shows the neck support 16 in the flat position.
- a first part 34 of the friction hinge 22 is held on the base element 36 of the headrest 10 .
- a second part 38 of the friction hinge 22 which can be pivoted relative to the first part 34 by overcoming the frictional force and thus enables the neck support 16 to be pivoted, is held on the neck support 16 .
- the neck support 16 has a frame element 40 which defines or forms a contour of the end region 24 .
- the frame element 40 can be connected at least indirectly in a rotationally fixed or stationary manner to the second part 38 of the friction hinge 22, as a result of which the frame element 40 can be configured particularly advantageously as a handle for pivoting the neck support 16.
- FIG. 5 shows the headrest 10 in the flat position in a further schematic perspective view.
- 6 shows the headrest 10 in the angular position in a further schematic perspective view.
- 5 and FIG. 6 show the headrest 10 according to FIGS. 1 to 4, with the cushion element 28 being removed or not being provided.
- both Figs. 5 and 6 show a side panel 44 which covers the base member 36 and is normally assembled for the operation of the vehicle seat 11.
- FIGS. 5 and 6 show a side element 46, which can serve as an operating element, for example for adjusting the height of the headrest 10, and/or as a holding element, for example for the fastening element of the cushion element 28.
- Comfortable and effective neck support can be achieved by the headrest 10 shown and the motor vehicle presented.
- the Neck support is advantageous because, in the event of an accident, the end region 24 can pivot back independently.
- the headrest 10 can be designed in such a way that it has the same external appearance as a headrest without a neckrest 16 . Due to the pivotable end area 24, the heating effect of the heating element 42 in the neck area can be increased in a particularly advantageous manner. In addition, a targeted neck massage by the massage device 32 is possible.
- the headrest 10 is thus particularly easy to operate and particularly convenient to use.
