AI Technical Summary

Technical Problem

Existing motor vehicle seats lack effective mechanisms for enhancing sound transmission and experience, particularly in the low-frequency range, without requiring additional components.

Method used

Incorporating side support cushions in the seat and backrest that can be filled with a fluid and adjusted via a compressor to create pressure changes corresponding to audio signals, acting as a low-frequency sound generator.

Benefits of technology

Enhances sound experience by transmitting low-frequency vibrations directly to the occupant through fluid-filled cushions, improving the auditory experience without adding new components.

Description

[0001] The invention relates to a motor vehicle according to the preamble of claim 1.

[0002] From JP H01-288 094 A, a seat is known that has a backrest and a seat. A resonance tube filled with air is arranged in the backrest and the seat. The resonance tube is connected to an electroacoustic transducer. When music is fed into the electroacoustic transducer, the music is converted into acoustic vibrations. The resonance tube begins to vibrate, and the vibration of the resonance tube is transmitted via an elastic element to the body of a person sitting on the seat.

[0003] From DE 10 2004 005 843 A1, a motor vehicle with a seat is known, wherein the seat has an inflatable seat unit. In its operating position, the seat unit is filled with a fluid, in particular with air. The inflatable seat unit is filled with a fluid via a compressor. The inflatable seat unit is deflated via a vacuum pump.

[0004] German patent DE 10 2007 036 987 A1 discloses a motor vehicle with one seat, in which two structure-borne sound generators or transducers are provided. One structure-borne sound generator is located in the seat surface and the other in the seat backrest. Each structure-borne sound generator has a flywheel that is set in motion. The structure-borne sound generators can be used to enhance a sound event in which structure-borne sound is generated depending on sound waves. In particular, the structure-borne sound generators enhance the low frequencies of the sounds emitted from a music source via the loudspeakers.

[0005] The object of the invention is to create a motor vehicle which has a seat which has side guide cushions that can be filled with a fluid, wherein the side guide cushions can be used for sound transmission.

[0006] This problem is solved by the features of claim 1.

[0007] A motor vehicle according to the invention has at least one vehicle seat with a seat surface and a backrest. At least one side support cushion is formed in the area of ​​the side surfaces of the seat surface and / or the backrest. The volume of the side support cushion can be changed by means of a fluid by increasing and / or decreasing the size of the side support cushion. The fluid is supplied via at least one compressor.

[0008] According to the invention, a device for playing back audio signals is provided, which is connected to means that convert the digital audio signals into electrical signals. At least one compressor is connected to these means. Each compressor causes a pressure change in the respective side guide cushion connected to the compressor, corresponding to the converted electrical signals.

[0009] In one embodiment, the fluid is gaseous and / or liquid and / or a gel.

[0010] The signals converted by the audio source advantageously generate pressure changes in the connected side guide cushions via the compressor, which lie in the low-frequency range, that is, in the range of 0 to 150 Hz.

[0011] One embodiment of the invention is described below.

[0012] From DE 10 2009 012 739 A1, a seat for a motor vehicle is known, comprising a seat surface and a backrest. Side support cushions are provided in at least one area of ​​the side surfaces of the seat surface and / or the backrest; the volume of these cushions can be varied by means of air. A compressor is provided for filling the side support cushions.

[0013] According to the invention, a compressor is provided for filling the side guide cushions in the area of ​​the side surfaces of the seat and / or the backrest, which is controlled by known means in such a way that the compressor delivers dynamic pressure changes to the respective side guide cushions based on electroacoustic signals.

[0014] The compressor according to the invention generates a sound in the side guide cushions that acts as a low tone or bass, corresponding to the frequency that can be generated in the side guide cushions.

[0015] In addition to supplying air to the side guide cushions, the compressor according to the invention also functions as a low-frequency generator. Audio signals emanating from known sound sources, such as radios, CD players, MP3 players, or the like, are processed using known means. The processed audio signals are fed into the compressor, which causes corresponding pressure changes in the side guide cushions.

[0016] These pressure changes cause vibrations that are directly perceptible in the seat. These vibrations are transmitted as sound sources, particularly intensely, to the person sitting in the seat or to other people in the vehicle interior. The sound experience is thus improved without the need for new components.

Claims

[1] Motor vehicle, with at least one vehicle seat having a seat surface and a backrest, wherein at least one side guide cushion is formed in the area of ​​side surfaces of the seat surface and / or the backrest, wherein the volume of the side guide cushion can be changed by a fluid by increasing and / or decreasing the size of the side guide cushion, wherein the fluid is supplied via at least one compressor, characterized by , that a device for playing back audio signals is provided which is connected to means that convert the digital audio signals into electrical signals, that at least one compressor is connected to these means and causes a pressure change in the respective side guide cushion connected to the existing compressor in accordance with the converted electrical signals. [2] Motor vehicle according to claim 1, characterized bythat the fluid is gaseous and / or liquid and / or a gel.
