Definitions
- the invention relates to a headrest with a device for noise suppression.
- the invention also relates to a vehicle seat.
- the object on which the invention is based is seen as providing an improved headrest and an improved vehicle seat. This object is achieved by a headrest and by a vehicle seat with the features of the respective independent claims. Advantageous configurations with expedient further training are specified in the dependent patent claims.
- a headrest configured to at least partially surround a head has a noise suppression device arranged on a side of the headrest facing a head position.
- a vehicle seat with such a headrest.
- the headrest or the vehicle seat can also have a display device on a side of the headrest facing away from the head position. If the user is in a "privacy mode" while listening to music or relaxing, the display device can be activated at the same time. Accordingly, the light lights up on the side facing away from the head, for example the back of the headrest or the vehicle seat. This light is an indication that the user does not wish to be disturbed or that the user may have difficulty hearing the passenger. In this way it is possible to signal to a passenger that the relevant occupant does not want to be disturbed.
- the headrest Since the headrest has a noise suppression device, the headrest user may not notice when a passenger speaks to him or her. Because the headrest or the vehicle seat also has a display device, this can be visually signaled to the passenger in a simple and intuitive manner.
- the display device can have a light source.
- the display device can be designed in such a way that the light source can be seen from the outside. Accordingly, the display device can be designed as a marker light.
- the display device can also have a light source and a diffuser. It can thus be configured as ambient light. For example, changing the color of the light can indicate that a specific listening mode is set.
- the display device can also have a luminous stone.
- This can be positioned, for example, under the headrest or in a recess in the vehicle seat.
- the luminous stone can have a transparent plastic into which, for example, an individualized inscription can be engraved or lasered. This inscription is illuminated by the light source and thus emphasizes the message in an improved way.
- the device for noise suppression can bring about the noise suppression through active or passive measures. For example, in the case of passive noise suppression, a surface of the headrest that faces the head can be structured accordingly or covered with a corresponding material, so that specific noises are suppressed.
- the noise suppression device has additional loudspeakers which produce what is known as anti-noise or anti-noise. This is artificially generated by the additional loudspeakers in order to eliminate or weaken the noises to be suppressed by means of destructive interference.
- an opposing signal can be generated which corresponds to that of the interfering sound but has an opposite polarity.
- the noise suppression device can be designed to suppress certain frequencies.
- anti-noise signals with corresponding frequencies are generated, for example, which erase these specific frequencies via destructive interference.
- ambient noise and the voices of passengers can be selectively switched off.
- the voices of other vehicle occupants or ambient noises are masked out hereby, but signal noises from other cars or the siren, for example, are not suppressed.
- the device which is suitable for suppressing specific frequencies, can thus increase safety when driving.
- the noise suppression device can also have loudspeakers for emitting desired signals.
- the user can listen to certain music programs or radio programs or make a phone call while background noise is hidden.
- FIG. 1 shows an example of a vehicle seat with a headrest according to embodiments.
- FIG. 2A is a rear view of a vehicle seat according to the embodiment.
- FIG. 2B is a front view of a vehicle seat according to embodiments.
- FIG. 2C shows a partial cross-sectional view of a vehicle seat according to embodiments.
- FIG 3 shows an example of a display device according to embodiments.
- Fig. 1 shows a vehicle seat 20 with a headrest 10.
- the vehicle seat 20 can be, for example, a vehicle seat for a motor vehicle. However, according to further embodiments, the vehicle seat can also be used in other vehicles, for example buses, airplanes, trains etc. or also in other areas, for example in the domestic area, in waiting areas and others.
- the vehicle seat 20 has a headrest 10 .
- the headrest 10 is configured to at least partially surround a user's head.
- the headrest further includes a noise suppression device 12 disposed on a side of the headrest 1 facing a head position. More specifically, the noise canceling device 12 is arranged on the inside of the headrest 10 .
- a display device 14 can be provided on a side of the headrest 10 facing away from the head position. As shown in FIG. 1, the display device 14 can enclose part of the exterior of the headrest. In this way, people who are not sitting directly behind the user can also see that the user is using the noise canceling function. For example, the display device 14 can be actuated at the same time as the noise suppression is activated.
- the display device can be strip-shaped forms. According to further embodiments, however, it can also be designed in any other way that enables visual recognition. According to further embodiments, the display device does not necessarily have to be attached to the headrest itself. According to further embodiments, it can be attached at any point on the vehicle seat 20 .
- the device 12 for noise suppression can also have loudspeakers 13 for emitting desired signals, for example music signals.
- the noise suppression device can be designed to suppress certain frequencies.
- Fig. 2A shows a schematic view of a vehicle seat 20 in which ei ne headrest 10 is integrated. 2A shows the side of the vehicle seat 20 facing away from the head position.
- the display device 14 can have a light source 16, for example, which can be integrated in the vehicle seat 20 or in the headrest 10, for example.
- the light source can be arranged over a recess 15 within the vehicle seat 20 or the headrest 10 and can illuminate a luminous stone 17, for example.
- the luminous stone 17 can have a transparent plastic, for example, in which an individualized inscription 19 can be engraved or lasered. In this way, a message, such as “sleep mode”, can be well emphasized.
- FIG. 2B shows a view of a front side, i.e. the side of the vehicle seat 20 with an integrated headrest 10 which faces the user.
- FIG. 2C shows a partial cross-sectional view of the vehicle seat 20. It can also be seen here that the light source is arranged in a recess within the vehicle seat, while further components of the display device are arranged below the light source 16.
- FIG. 3 shows a schematic view of a display device 14 in which the display device has a light source 16 and a diffuser 18 . In this way, an ambient light can be realized.
- the invention described relates on the one hand to a headrest 10 which, as a separate element, has the device for noise suppression and, if necessary, further components.
- the headrest 10 can also be integrated into a vehicle seat 20 or attached to it.
- the elements described can also be components of a vehicle seat, as is shown, for example, in FIGS. 2A to 2C.
- a user can be put into the so-called “privacy mode” with the headrest described, as a result of which noises from the front passenger are perceived less strongly by the user.
- a desired signal for example a piece of music or a radio program, can be broadcast so that the user perceives it in an amplified manner.
- the headrest has a display device
- a passenger can be informed that the user does not want to be disturbed. Furthermore, the passenger can be signaled that the user has difficulty hearing the occupants sitting behind him. Through this implementation, the safety of the user and also of the passengers can be increased to a greater extent.
