Description

The present disclosure relates to a vehicle seat for a motor vehicle and/or a motor vehicle comprising the vehicle seat.

Known vehicle seats include massage and/or vibration elements for improved seating comfort, for example, which are embedded in the respective seat foam (of the seat part or the backrest). For this purpose, specific recesses are provided for such elements, e.g. audio shakers and/or vibration motors, into which the elements are inserted, glued or clipped. This is done as individual parts.

However, integrating the elements into the seat foam is time-consuming and always leads to an increase in the number of foam variants and thus to additional costs. In addition, care is taken to ensure that these elements do not overlap with pneumatic massage chambers on a massage mat, for example.

EN 10 2019 115 348 A1 describes a vehicle seat with upholstery and a seat cover and also a first massage device and a second massage device. The first massage device has at least one first massage element and the second massage device has at least one second massage element. The first and the second massage element are of different types, the type being selected from: fluid-loaded massage element, mechanical massage element, mechatronic massage element and dielectric massage element.

EN 10 2017 205 135 A1 describes a control arrangement in a vehicle for controlling at least one comfort function of the vehicle, with at least one control unit that controls at least one device providing the comfort function; and at least one detection unit that is connected to the control unit. The detection unit detects an orientation of at least part of a vehicle seat in a vehicle interior and transmits the detected vehicle seat orientation to the control unit, which controls the comfort function of the device depending on the detected vehicle seat orientation.

EN 10 2011 117 927 A1 describes a motor vehicle seat which has a backrest and a massage device provided on the backrest for back massage. The massage device has electrically and/or mechanically actuated pressure elements for exerting pressure on the back of an occupant. The pressure elements are arranged at different heights along the longitudinal extension of the backrest defined between the seat part and the head region of the backrest, with lower pressure elements provided essentially in the lumbar region of the backrest and upper pressure elements located above it. The backrest is designed in the region of at least one of the upper pressure elements such that at least when the at least one upper pressure element is actuated, a force can be exerted on an occupant perpendicular to the surface of the backrest, which force is higher in this region than in the region of the lower pressure elements.

EN 10 2014 119 658 A1 describes a vehicle seat having a seat base and a seat back, each having a spring structure, planar electroactive polymer actuators each having a first state and coupled to one of the spring structures, and a controller in communication with the actuators and configured to supply a predetermined electrical input energy to one or more of the actuators. The predetermined electrical input energy deforms at least one of the actuators to a second state.

EN 10 2016 010 651 A1 describes a vibration module for integration into a motor vehicle seat, with a plurality of vibration elements and with a first flat cover layer and a second flat cover layer, wherein the vibration elements are arranged between the first cover layer and the second cover layer. The positions of the vibration elements are fixed relative to the first cover layer and/or second cover layer.

EN 10 2015 215 171 A1 describes a method for controlling massage units in a seat, comprising the following steps: playing an acoustic entertainment signal by means of a playback device, and controlling massage units integrated in the seat based on the acoustic entertainment signal by means of a control device.

Furthermore, the EN 20 2019 100 400 U1 a device for a vehicle seat with at least two air cushions, wherein each air cushion can be individually filled with air via an air supply system.

Against the background of this prior art, the object of the present disclosure is to provide a device which is suitable for enriching the prior art.

The problem is solved by the features of the independent claims. The subordinate claims and the dependent claims each have optional further developments of the revelation on the content.

The task is then solved by a vehicle seat for a motor vehicle.

The vehicle seat comprises a plurality of seat components having a seat surface and a backrest. The plurality of seat components may optionally further comprise a headrest, an armrest and/or a footrest.

The vehicle seat includes a massage mat disposed, e.g. embedded, within at least one of the plurality of seat components.

The vehicle seat comprises at least one vibration element. The at least one vibration element is arranged, e.g. embedded, on the massage mat within the at least one of the plurality of seat components.

The at least one vibration element is inserted (and/or accommodated) in a foil bag. The foil bag is formed at least in sections by the massage mat (and/or at least one of several air chambers of the massage mat).

The vehicle seat described above offers a number of advantages. Among other things, an arrangement or fastening concept of the at least one vibration element on the massage mat is provided, which aims to combine vibration elements with massage elements (of the massage mat). Recesses in the foam, e.g. the backrest, which in known vehicle seats have to be provided specifically and exclusively for the at least one vibration element, are therefore no longer necessary. This advantageously simplifies the integration of the at least one vibration element and avoids or at least significantly reduces the number of variants of the at least one of the several seat components or the foam of the at least one of the several seat components.

Possible further developments of the vehicle seat described above are explained in detail below.

The backrest can have a backrest surface and the massage mat can be arranged inside the backrest. The at least one vibration element can be arranged inside the backrest on a side of the massage mat facing or facing away from the backrest surface.

Placing the at least one vibration element on the massage mat, i.e. on the side of the massage mat facing the back contact surface, advantageously leads, for example, to an increase in intensity during massage operation, since the rigid geometry of the at least one vibration element is incompressible.

The at least one vibration element can be attached to the massage mat and/or pre-assembled. This advantageously eliminates the need for separate assembly of the at least one vibration element and the massage mat. Instead, pre-assembly can be carried out and the pre-assembled arrangement can be delivered when the vehicle seat is assembled.

The at least one vibration element can comprise (at least) one structure-borne sound transducer and/or be designed as a structure-borne sound transducer. The (at least) one structure-borne sound transducer can be a shaker, audio shaker, mover and/or exciter. Alternatively or additionally, the at least one vibration element can have a vibration motor.

The massage mat can be designed as a pneumatic (and/or electro-pneumatic) massage mat, which can have several air chambers.

The multiple air chambers can be arranged in a grid and/or matrix structure, e.g. parallel to the backrest surface within the backrest. Furthermore, two or more of the multiple air chambers can be arranged, e.g. adjacent to one another, e.g. at a height or between the backrest surface and a back surface of the backrest opposite the backrest surface.

The plurality of air chambers can be made of a flexible material, e.g. a film and/or metal foil. A respective volume and/or a respective internal pressure of the plurality of air chambers can be changed (e.g. separately) by supplying or removing air (or another gas). The respective volume and/or the respective internal pressure of the plurality of air chambers can be changed to produce a massage effect, e.g. according to a predetermined pattern.

The vehicle seat can, for example, comprise a (controllable) pump device for supplying air (or another gas) to the massage mat and/or removing air from the massage mat.

The at least one vibration element can be arranged, optionally attached, to one of the plurality of air chambers. The at least one vibration element can comprise a plurality of vibration elements, wherein, for example, each of the plurality of vibration elements is arranged, optionally attached, to one of the plurality of air chambers.

At least one electrical line for supplying current to the at least one vibration element can be laid in a spiral and/or wave-like manner around several of the air chambers.

The foil bag can be formed (in addition to the massage mat) from at least one foil, e.g. metal foil. The at least one foil can comprise several, e.g. three, foils. The at least one foil can be attached, e.g. welded and/or glued, to the massage mat, e.g. on one side of one of the several air chambers to form the foil bag.

The massage mat (or the plurality of air chambers) and the at least one film can comprise an identical (or similar) weldable film material and/or be formed from the identical (or similar) weldable film material.

At least one electrical line for supplying current to the at least one vibration element can be formed, printed, placed and/or threaded on the film pocket.

The vehicle seat can comprise a support layer which can be arranged inside the backrest on a side of the massage mat facing away from the backrest surface.

The at least one vibration element can be arranged between the massage mat and the carrier layer.

The headrest can be attached to the backrest or be formed as part of the backrest.

The backrest can have a first section and a lumbar support section, wherein the first section can be arranged between the headrest and the lumbar support section. The massage mat and the at least one vibration element can be arranged in the first section and/or in the lumbar support section.

The at least one vibration element can have a (rigid) housing and/or be incompressible.

A geometry of the at least one vibration element can be designed to influence (e.g. improve) a massage effect of the massage mat.

An internal pressure and/or a volume of the massage mat (and/or the multiple air chambers) can be controllable depending on an operation of the at least one vibration element. The internal pressure of the massage mat can advantageously influence the behavior of the at least one vibration element. This desired effect can, for example, lead to a significantly more intense experience of the vibration behavior of the at least one vibration element.

The carrier layer can be designed, for example, as a flexible layer and/or flexible mat.

The vehicle seat can further comprise a padding, e.g. an air-permeable padding, which is arranged on the backrest surface and/or forms the backrest surface.

The backrest can have a main body made of foam. The massage mat and the at least one vibration element (and optionally the carrier layer) can be embedded in the main body and, for example, inserted, glued and/or clipped.

The vehicle seat can be a driver's seat and/or a passenger seat.

The above can be summarized in other words and in a possible more concrete embodiment of the disclosure as described below, whereby the following description is not to be interpreted as limiting the disclosure.

According to the present disclosure, vibration elements, e.g. shakers and/or exciters, can be deliberately combined with pneumatic massage mats.

The at least one vibration element can be placed on one or more air chambers of the massage mat. This can lead to an increase in intensity during massage operation because the rigid geometry of the at least one vibration element is incompressible. Alternatively, or in addition, the at least one vibration element can be placed under the air chambers of the massage mat.

In both cases, at least one vibration element is connected to the massage mat and can be delivered with it, for example. Separate assembly is therefore not necessary.

The at least one vibration element can be inserted in a foil bag, wherein one side of the foil bag can represent one side of an air chamber.

If at least one vibration element is placed on the air chambers, the electrical cable for supplying power to the vibration element can be laid in a spiral around the air chambers. Alternatively, the wires of the electrical cable can also be printed on the film.

The massage effect can be improved by a targeted geometry of the at least one vibration element. Furthermore, the internal pressure of the air chambers can influence the vibration behavior of the at least one vibration element. This is intentional and can lead to a significantly more intense experience, e.g. if the at least one vibration element is arranged under the air chambers.

Furthermore, a motor vehicle comprising the vehicle seat described above is provided.

The motor vehicle may be a passenger car, in particular an automobile, or a commercial vehicle, such as a truck.

What is described above with reference to the vehicle seat also applies analogously to the motor vehicle and vice versa.

The vehicle seat 1 further comprises a massage mat 5, which is arranged within at least one of the several seat components. In the embodiment shown, the massage mat 5 is arranged or embedded in the backrest and is designed as a pneumatic massage mat that has several air chambers 5-1, 5-2.

The vehicle seat 1 further comprises at least one vibration element 6, which is arranged on the massage mat 5 within the at least one of the several seat components. The at least one vibration element 6 can be attached to the massage mat 5 and/or pre-assembled. In the embodiment shown, the vibration element 6 is arranged on a side of the massage mat 5 facing or facing away from the backrest surface 4 within the backrest 3.

For simplified representation, 1 purely by way of example, only one vibration element 6 is shown, which is arranged on a side of an air chamber 5-1 of the massage mat 5 facing the back contact surface 4. For example, the vehicle seat 1 can also comprise several vibration elements 6, wherein each of the several vibration elements 6 can be arranged, for example, on a respective air chamber 5-1.

It should also be noted that the massage mat 5 and the at least one vibration element 6 are arranged within the backrest 3, e.g. embedded, and therefore cannot be seen from the outside when the vehicle seat 1 is moved or installed. The representation of the massage mat 5 and the vibration element 6 in 1 is therefore for illustrative purposes only.

The backrest 3 has a first section 3-1 and a lumbar support section 3-2, wherein the first section 3-1 is arranged between the headrest 8 of the vehicle seat 1 and the lumbar support section 3-2. The massage mat 5 (or a section of the massage mat 5 with the air chambers 5-1) and the at least one vibration element 6 are arranged in the first section 3-1. The massage mat 5 can extend into the lumbar support section 3-2, wherein, for example, a section of the massage mat 5 with the air chambers 5-2 can be arranged in the lumbar support section 3-2. Alternatively, or additionally, the at least one vibration element 6 can also be arranged on the massage mat 5 in the lumbar support section 3-2.

The at least one vibration element 6 can comprise a structure-borne sound transducer and/or be designed as a structure-borne sound transducer. The structure-borne sound transducer can be, for example, a shaker and/or a mover.

2 shows schematically an arrangement (a) in which the vibration element 6 is arranged on the side of the massage mat 5 facing the back contact surface 4, and an arrangement (b) in which the vibration element 6 is arranged on the side of the massage mat 5 facing away from the back contact surface 4.

As shown, the vehicle seat 1 can further comprise a carrier layer 7 which is arranged within the backrest 3 on a side of the massage mat 5 facing away from the back contact surface 4.

In arrangement (a), the vibration element 6 is arranged between the massage mat 5 and the carrier layer 7. Furthermore, the vibration element 6 is inserted in a film pocket 9, wherein the film pocket 9 is formed, in addition to a film 9-1, at least in sections by the massage mat 5 (or an air chamber 5-1). The carrier layer 7 can, for example, have a slot through which the vibration element 6 can be inserted into the film pocket 9.

An electrical line 10 for supplying current to the vibration element 6 can be passed through the film pocket 9. Alternatively, or additionally, the electrical line 10 can be formed, printed, laid and/or threaded on the film pocket 9, e.g. on a section of the carrier layer 7.

In arrangement (b), the vibration element 6 is also placed in the film pocket 9, with the film pocket 9 in this embodiment being formed at least in sections by the massage mat 5 (or an air chamber 5-1). For this purpose, the film 9-1 can be attached, e.g. welded, on one side to a free side of the air chamber 5-1. The electrical line 10 for supplying current to the vibration element 6 can be laid in a spiral and/or wave-like manner around several of the air chambers 5-1. These several air chambers 5-1 can, for example, be arranged adjacent to one another between the back contact surface 4 under the carrier layer 7.
