Description

The invention relates to a vehicle seat having a backrest.

Various designs of vehicle seats are known from the prior art. For the purposes of the invention, a vehicle seat means any seat that is in a moving vehicle, be it on water, on land, in the air or in space. Such vehicle seats not only provide a comfortable sitting for the user, but there are - depending on the method of use and users - to perform different functions in addition. On the one hand, the vehicle seat serves as an interface to the vehicle, with which one is stationarily connected via a safety belt in order, for example, not to be thrown through the window of a motor vehicle in the event of an accident. However, other functions - which are always optional - to meet, for example, there may be a need to make phone calls while moving a motor vehicle to change the backrest of the vehicle seat via a control lever relative to the seat part or on a passenger seat, the ability to read to have during the dark. In the known seats, this is achieved in that for each individual function that is desired, a single component is used and is arranged at different positions of the vehicle seat. In each case different and individual optical configurations of covers are used.

From the DE 42 11 471 C2 For example, a motor vehicle seat with a safety belt system is known which has at least one shoulder belt which emerges from the backrest through a slot-like opening which is at least largely adapted through a cross-sectional shape of the shoulder belt. In this case, the slot-like opening is provided in a cover part, which is arranged so as to be pivotable about an axis extending at least approximately parallel to the passage direction of the shoulder belt on the wall of the backrest. The slot-like opening is aligned with a passage of the wall of the backrest, whose cross-sectional area is equal to the area swept by the slot-like opening during a pivotal movement of the cover between two predetermined end positions.

The object of the invention is to present a vehicle seat that is multifunctional and the different functions can be offered very easily on the vehicle seat.

The object is achieved by a vehicle seat having the features of patent claim 1. The vehicle seat according to the invention in this case has a module which is inserted into the shoulder area or above it. This makes it possible to realize a whole range of functionalities in such a module. However, since such a module should not be configured over a large area, it is arranged according to the invention interchangeably in said area. This makes it possible that the vehicle seat can always be adjusted to the individual needs of the user. Should the user not require functionality, a simple cover member is used as the module to close the opening in the seat back to provide an overall aesthetic impression of the vehicle seat while also minimizing the risk of injury to the user of the vehicle seat. On the other hand, if the user requires functionality, he can select the appropriate functional element and use it in a very simple manner instead of the cover element. This is possible because there is a modular design, in which the respective module must be solved only from its attachment and another module with the desired functionality must be used. For safety-relevant parts as a module, for example the deflection for a three-point seat belt, the installation must be carried out at the factory.

Preferably, a belt deflection point (safety-relevant part), a reading lamp, a loudspeaker, a microphone, an operating lever or a combination of one or more of the mentioned embodiments are used as functional elements. Advantageously, the respective function of the functional element is oriented towards the front side and / or the rear side. When the function is oriented toward the front, a user of the vehicle seat in which the module is installed can use the respective function. On the other hand, if the function is oriented towards the rear, this can be done by a person located behind the vehicle seat, for example in the case of a passenger car the person sitting in the rear or a person in bed in a truck cabin.

A further advantageous development of the invention provides that the module is arranged on one side of the backrest. This ensures on the one hand, that the main function of the vehicle seat, namely a secure connection of the user is ensured with the vehicle and even when large forces of the head does not strike against a module, but that enough space for a headrest is available. On the other hand, the module and its anchoring can be designed in such a way that it can be inserted into the vehicle seat in a particularly simple manner and given a very good integration.

Preferably, the module is integrally integrated with a vehicle seat with integrated headrest in the backrest. In a vehicle seat with a separate headrest, however, the module is preferably arranged on top of the backrest.

A further advantageous embodiment of the invention provides that the module is arranged in alignment with the front surface of the backrest. As a result, on the one hand, an excellent appearance of the backrest is achieved because it is a smooth front surface. On the other hand, however, this also serves to prevent injury to the user of the vehicle seat, as it would be feared if the module would protrude beyond the front surface of the vehicle seat.

A further advantageous embodiment of the invention provides that two modules are arranged symmetrically to the vertical center axis of the backrest. Again, this achieves an excellent visual effect and, moreover, it is possible to integrate several different functionalities within a single vehicle seat.

Further advantages and details of the invention will be explained with reference to the embodiments illustrated in the figures. Show it:

1 a schematic view of a first vehicle seat according to the invention,

2 Various embodiments of inventive modules and

3 a schematic view of a second vehicle seat according to the invention.

In 1 is a first embodiment of a vehicle seat according to the invention 1 shown. This has a seat part 8th and a movable backrest 2 on. Since such embodiments of the prior art are well known, is on the individual components of such a vehicle seat 1 not discussed in detail, unless they are essential to the invention.

Inside the backrest, into which a headrest 6 is integrated, are two modules of the invention 3 used. The modules 3 are here in or just above the shoulder area 7 , ie the area in which a user of the vehicle seat 1 his shoulders are positioned. The two modules 3 are mirror-symmetric with respect to the central axis 9 the backrest 2 arranged. This results in a kind of waist in the area or above the shoulder area 7 ,

The modules are safe with the backrest, not shown anchors 2 connected. It is a detachable connection, so the two modules 3 from their anchorages and through another module 3 can be replaced. This allows the vehicle seat 1 to be fitted to the needs of the user. Of course, for safety-relevant modules, this must be done by trained professionals, regularly at the factory.

In the illustrated embodiment, the left-to-see module 3 as a reading lamp 5b educated. The reading lamp 5b but does not emit light to the front but towards the back. This allows a person to sit in the rear on a vehicle seat behind the vehicle seat shown 1 is located, even in the dark read. It goes without saying that it would be just as possible to use the reading lamp 5b also in the direction to the front to arrange. In addition, it would also be possible to have a reading lamp 5b both in the direction of the front and in the back. For this it is only necessary, the module shown 3 to replace it with another module with the corresponding functionality.

It is already clear that such a vehicle seat according to the invention 1 very easy on the individual needs of the user of the vehicle seat 1 can be adjusted. This becomes even clearer when the in 2 illustrated various embodiments of the module 3 be explained (see below).

The other module shown on the right 3 is in the form of a cover element 4 educated. Such a cover element 4 is used when there is no functionality at the point where the module is 3 is needed. This is indicated on the one hand for aesthetic reasons, since the vehicle seat 1 So that gives a coherent overall picture and no gap in the backrest 2 having. In addition, the module closes 3 positively with the recess in the backrest 2 off and is flush with the front surface of the backrest 2 educated. This is a risk of injury to the user of the vehicle seat 1 in the area of the module 3 prevented.

It goes without saying that even one module 3 or even more than two modules 3 inside the backrest 2 of the vehicle seat 1 can be arranged. These do not necessarily have to be on the outside of the backrest 2 be positioned. For example, it would be possible on the connecting line between the two illustrated modules in the region of the central axis 9 another module 3 to arrange. Again, that applies the modules 3 as optimally as possible to the wishes and needs of the user of the vehicle seat 1 be matched.

In 2 is a series of different modules 3 - but this is by no means conclusive - illustrated.

The module 3 can as a belt deflection point 5a be educated. This makes it possible that the seat belt, which is mandatory, virtually within the vehicle seat 1 and thus an excellent integration of this essential component into the overall concept of the vehicle seat 1 is guaranteed.

The module 3 Can also be used as a reading lamp 5b (as already above 1 described) may be formed. As stated above, the light of the reading lamp 5b both to the front and to the rear of the vehicle seat 1 be directed. When directed to the front, the user of the vehicle seat may 1 These use when he needs light in the dark, for example, to write a note. When the reading lamp 5b towards the back, can - as above to 1 running - a person who is in the rear, reading during the dark. But it is also possible that the vehicle seat 1 is arranged in front of a driver's cab in a truck. Then the reading lamp serves 5b as a reading light on the bunk.

A module 3 in the form of a hands-free kit for telephoning with a loudspeaker 5c and a microphone 5d is also in 2 shown. This allows the user of the vehicle seat 1 while driving with both hands on the steering wheel phone. However, it is equally possible that only one of the two functionalities in the module 3 is included. For example, only one speaker 5c be present so that the user of the vehicle seat 1 Listening to music.

The cover element 4 is already up too 1 been described. It serves, if no functionality is needed, the opening within the vehicle seat 1 to close.

Another embodiment of the module 3 is as a control lever 5e shown. This makes it possible, one or more previously defined operating functions conveniently from the vehicle seat 1 from perform. For example, shoulder adjustment or headrest is possible 6 to adapt to the respective user.

It goes without saying that the illustrated form of the modules 3 was chosen only as an example. It is basically any other conceivable form for the modules 3 possible. Then all you have to do is anchor it in the backrest 2 coordinated and the design of the backrest 2 adapted to it.

In 3 is another embodiment of a vehicle seat according to the invention 1 shown. In the following, only the differences from the first embodiment of the 1 discussed in more detail. Identical or equivalent elements are provided with the same reference numerals.

The only essential difference between the in 3 illustrated vehicle seat 1 and that one 1 is that the backrest 2 no integrated headrest 6 having. The illustrated headrest 6 is about two bars 10 with the backrest 2 connected. On top of the backrest 2 are again two modules 3 arranged. These have one opposite the ones in the 1 and 2 illustrated modules other form. In the module shown on the left 3 it is a Gurtumlenkpunkt 5a , The safety belt is not shown for clarity. The module shown on the right 3 is - as above in 1 - As a cover element 4 executed.

Again, how to 1 already stated that individually depending on the needs of the user of the vehicle seat 1 the appropriate module 3 can be used. In addition, there could be other modules here as well 3 or even just a module 3 be arranged.

For the purposes of the invention, the term vehicle seat 1 very far to understand, so also a bench under vehicle seat 1 falls.
