Description

The present invention relates to a corona for a vehicle seat. The vehicle seat can be used in particular in a motor vehicle. Moreover, the invention relates to a vehicle seat comprising such a corona.

From the prior art is known to arrange inflatable air cushion in a vehicle. Such air cushions serve as a restraint system for a driver in the event of a crash of the vehicle. In addition, various comfort functions for a user of a vehicle are known from the prior art. Such comfort features include, in particular, neck vents via headrests of a vehicle seat, ventilation rings in a roof of a vehicle, air vents in instrument panels, doors, pillars, and the roof of the vehicle, and light outlets in the instrument panel, door, pillars, and roof of the vehicle. All these functions, both the restraint function and the comfort function, are based on a seat in which the user has a defined orientation. This is sufficient for conventional vehicles, since it can be assumed that a vehicle seat will usually be oriented in the direction of travel.

In driverless vehicles, however, such an orientation of the vehicle seat is no longer specified. Rather, it is possible here that the vehicle seat may have any orientation within the vehicle. In this case, the functional elements described above are no longer completely usable.

It is also known from the prior art to place additional air cushion units on child seats. This is in the document DE 101 57 707 A1 described. The attachable unit is an additional protection for children in child safety seats because in the event of a crash an air cushion is inflated in front of the child's body and two air cushions on the side of the child's head. In this way, the child is protected in an accident. However, such a concept is not universally applicable. Thus, on the one hand, retention by the air cushion unit is only limitedly possible because the head restraint to which the air cushion unit is to be fastened is not designed for retention forces. In addition, the air cushion has to cover a large Auffaltweg each, in order to serve as a retaining element starting from the air cushion unit. Finally, the air cushion can not optimally support a body of the user of the seat, since due to the design of the air cushion unit and the resulting shape of the air cushion always a distance between the air cushion and the user's body must be maintained.

It is an object of the invention to improve a vehicle seat such that it allows for safe and reliable provision of safety features and / or comfort features with simple and cost-effective production and assembly.

This object is achieved by the features of independent claim 1. The subclaims have preferred developments of the invention to the content.

The object is thus achieved by a corona for a vehicle seat. The corona is attachable to the vehicle seat and includes a base member attachable to a seat back of the vehicle seat. In addition, the corona comprises a functional element which is arranged on or in the base element. The functional element allows an action on the user. It is provided that extends the base member at least ring segment above a head of the user on the driver. Due to the at least ring segment shape several advantages can be achieved. This ensures, on the one hand, that the entire body of the user can be reached for the functional element. This is achieved by the at least ring segment shape in that there is always a portion of the base member in an area above the body of the user. In particular, it is possible to act from the front, from behind or laterally on the user's body. At the same time, an upward view is not restricted for the user. Rather, the user can look through the at least ring-segment-shaped base element here. In this way, an acceptance of the corona for use in vehicles is improved. By attaching the corona to the vehicle seat, the provision of the functional element is independent of an orientation of the vehicle seat. Thus, it is not necessary that the vehicle seat must have a defined orientation in order to provide safety functions and / or comfort functions for the user of the vehicle seat. Under an at least ring-segment-shaped base member is to be understood that this has either a ring segment shape or a ring shape.

The corona preferably has an inflatable air cushion. The inflatable air cushion is inflatable in an accident situation and represents a restraint device for the user. In particular, it is provided that the fully inflated air cushion comes into contact with the user. In this way, in particular, it is possible for the inflatable air cushion to replace other restraint systems, such as a restraint belt. Due to the at least ring segment shape of the base element, the air cushion has a tubular shape, so that a immediate contact with the user is reliably and safely possible. At the same time, due to the at least ring segment shape, an inflation path that the air bag must travel to fully inflated state is minimized. This allows a safe and reliable restraining the user of the vehicle seat in the event of an accident of the vehicle in which the vehicle seat is mounted.

Particularly advantageously, the functional element has a first inflatable air cushion and a second inflatable air cushion. Both the first inflatable air cushion and the second inflatable air cushion are advantageously arranged in the base element. In this case, the first air cushion serves as a retaining device for a head of the user and the second air cushion as a retaining device for a torso of the user. In particular, the first inflatable air cushion and the second inflatable air cushion are independently inflatable. Thus, it is particularly advantageous that the first air cushion and the second air cushion can be inflated from different directions from the base element. Thus, it is advantageously provided that the first air cushion exits from a lower region of the base element when it is inflated, while the second air cushion exits from an upper region of the base element when it is inflated. Again, due to the at least ring segment shape of the base member, an inflation path that both the first air bag and the second air bag has to travel to be transferred to the fully inflated condition is minimized. Due to the tubular nature of the first air cushion and the second air cushion, which results from the at least ring segment shape of the base element, an immediate contacting of the user's body is made possible. Thus, it is preferably provided that the first air cushion comes into direct contact with a head of the user when the first air cushion is fully inflated. Likewise, the second air bag can be brought into contact with the upper body of the user when it is fully inflated. Likewise, due to the tubular nature of the second air cushion, it is ensured that it can surround the first air cushion. Thus, the first air cushion in its inflated state is advantageously at least partially disposed within the second air cushion. The first air cushion and the second air cushion thus provide a safe and reliable restraint of the user of the vehicle seat to which the corona is attached. In this case, the retention of the user is independent of an orientation of the vehicle seat itself, so that when using the vehicle seat in a vehicle, the retention by the first air cushion and the second air cushion can always be done safely and reliably.

Particularly advantageously, a partial region of the first air cushion is connected to the base element via a first retaining element. The first holding element is in particular formed strip-shaped. It is likewise provided that a second retaining element connects a subregion of the second air cushion to the base element. Also, the second holding element is preferably formed band-shaped. In this way, a retention effect of the first air cushion and / or the second air cushion is improved. The first holding element and / or the second holding element serve in particular as a restraint belt. Thus, the restraint belt is brought into an area in front of the user by the inflation of the first air cushion and / or the second air cushion. A retention of the user thus takes place via the first air cushion and the first holding element and via the second air cushion and the second holding element. In this way, it is also possible to absorb large forces, so that the first air cushion and the second air cushion with the respective first holding element and second holding element represent a complete restraint device for the user. Additional restraint devices, in particular a safety belt, are thus not necessary, but can supplement the restraining function of the airbags and the retaining elements.

Particularly advantageously, the functional element has an air conditioning element. The air conditioning element is mounted in particular within the base element. At least the head and / or the upper body of the user can be conditioned with the air-conditioning element. Under air conditioning element is to be understood as such an element which is designed to conduct cooled or heated air to the user. Due to the at least ring segment shape of the corona, the cooled or heated air is optimally distributed to the user. In particular, the cooled or heated air is steerable from different directions to the user. In turn, it is advantageously possible that the conduction of cooled or heated air is independent of an orientation of a vehicle seat on which the corona is mounted. Rather, the user of the vehicle seat on which the corona is mounted is thus enabled to maintain a one-time adjustment of the air conditioning element for all orientations of the vehicle seat. Thus, the comfort for the user is noticeably increased.

Particularly advantageously, the air conditioning element has at least one nozzle. The nozzle is arranged in the base element. In particular, it is also provided that the nozzle is adjustable. Thus, the airflow from the air conditioning element can be safely and reliably directed to the user. The user can regulate the airflow through the preferred adjustability of the nozzle. This regulation is thus suitable for all seat orientations of the vehicle seat on which the corona is used. Thus, an independence of the user-directed air flow is given by an orientation of the vehicle seat on which the corona is used. This in turn increases the comfort for the user.

Advantageously, the functional element has a spectacle element. The spectacle element is fixed in the base element or on the base element and pivotable into a viewing area of the user. In addition, objects can be displayed in the spectacle area. Particularly advantageously, the objects are displayed in superposition with the environment actually visible by the spectacle element. This means that the spectacle element is advantageously either transparent or detects the actual surroundings via a camera element. For the user thus gives the impression that the spectacle element would not exist. However, the presence of the spectacle element allows the actual environment to be overlaid with other objects, in particular with information about the environment. This may preferably include displaying navigation information. Alternatively, it is preferably provided that the spectacle element is not transparent. Thus, the goggle element is for displaying movies and / or pictures for the entertainment of the user. Due to the unfoldability of the spectacle element from the base element, a comfort for the user is increased, since in particular no glasses must be worn. Rather, the wearing of the spectacle element takes over the base element. Thus, the glasses element is also suitable for those users who already wear their own glasses. This is achieved in that the spectacle element can be folded out of the base element analogously to a visor.

The functional element also preferably comprises a light element or a reading light. It is provided that the light element is designed for illuminating the user over a large area. In particular, the light element is arranged on the base element via an arm and serves to illuminate the user through the at least ring segment shape of the base element. In this way, the user can be illuminated over a large area, the light element in particular serving as an artificial sun. In this way, the user can be given the feeling of brightness. Likewise, the user can be illuminated with ultraviolet light to obtain effects such as in a solarium. Alternatively, the functional element comprises a reading light. The reading light is preferably integrated in the base element. The reading light is used for focused illumination of a limited area. In this way, for example, a document or a book that the user wants to read in the dark, illuminated, while other areas are not illuminated. Thus, other users who are in an environment of the vehicle seat having the corona are preferably not disturbed.

The functional element preferably also has a loudspeaker system. The loudspeaker system allows the user to be sounded. Since the base element extends at least in the manner of a ring segment over the user's head, it is possible to sound from different directions. In this way, the user can advantageously be given the impression of a spatial sound experience. This means that the sound is controllable so that the user gets the feeling that the sound of the sound would act on the user from any predeterminable direction. Thus, in turn, a comfort of the user is increased. In particular, in turn, the sound is independent of an alignment of the vehicle seat to which the corona is mounted, in particular a sound for each vehicle seat of a vehicle is individually adjustable when a vehicle has a plurality of vehicle seats with the described corona.

The base member advantageously comprises a first ring segment-shaped element and a second ring segment-shaped element. The first ring segment-shaped element and the second ring segment-shaped element are in particular spaced from one another. Furthermore, it is provided that the first ring-segment-shaped element on one side of the user extends annularly over the head of the user, while the second ring-segment-shaped element extends on another side of the user like a ring segment over the head of the user. In this way, in particular an opening is present, which lies in a direction in front of the user. In this way, in particular, an opening remains in the previously described tubular air cushion, so that a field of vision of the user forward through the air cushion is not completely limited.

The invention further relates to a vehicle seat. The vehicle seat includes a corona as previously described. Thus, safety functions and / or comfort functions are provided on the vehicle seat, which are independent of an orientation of the vehicle seat.

Particularly advantageously, the base element is formed integrally with the backrest of the vehicle seat. This is particularly advantageous when the vehicle seat is an integral seat. By integrally forming the base member and backrest is also achieved that a power transmission between the base member and Backrest is optimized. Power transmission always occurs when the functional element of the corona comprises an air cushion which serves as a restraint device for the user. Thus, a safe and reliable retention of the user is achieved. In addition, the base member is securely and reliably attached to the vehicle seat.

The base element is advantageously designed to be pivotable and / or displaceable relative to the backrest of the vehicle seat. For this purpose, the base element may in particular have a joint and / or a rail system. Due to the displaceability, the base element can be adapted to different seat sizes of a user. This ensures that the corona is always above the user's head. A pivotability is particularly advantageous if this pivotability is formed about a transverse axis of the vehicle seat. In this way, the base member can be pivoted to allow easy entry and exit from a vehicle having such a vehicle seat. The pivoting can in particular be done automatically, the pivoting can be particularly advantageously coupled with unlocking and / or opening a vehicle door.

The backrest of the vehicle seat is advantageously designed such that it always maintains a predefined minimum contact pressure against the upper body of the user by adjusting a seat angle. It may be the case that the user bends forward in his seat, whereby no contact between his upper body and the vehicle seat, in particular the backrest, is present. In this case, the corona, in particular the base element would no longer be optimally aligned. Should a crash occur, a previously described air cushion could no longer optimally fulfill the restraint function. To avoid this, the backrest follows the upper body of the user. This allows a safe and reliable restraint of the user regardless of a sitting position of the user. The consequences of the backrest is achieved in that the backrest is moved in the direction of the user until it is pressed with the described minimum contact pressure to the upper body of the user.

The vehicle seat is advantageously an integral seat. Alternatively or additionally, a headrest is attached to the base element of the corona. Advantageously, the headrest is displaceable relative to the base element.

1 schematically shows a vehicle seat 2 with a corona 1 according to an embodiment of the invention in a first view. 2 shows the vehicle seat 2 with the corona 1 according to the embodiment of the invention in a second view. The vehicle seat 2 is in particular designed as an integral seat, which means that a belt element 21 for restraining a user 6 of the vehicle seat 2 directly to the vehicle seat 2 is arranged. The vehicle seat 2 also has a backrest 4 on, on the upper body 10 the user 6 is supportable. On the backrest 4 is the corona 1 attached. In particular, a holding element 3 the corona 1 on the backrest 4 attached. There is also a headrest 7 for supporting a head 5 the user 6 present, with the headrest 7 advantageously on the base element 3 the corona 1 is attached. The headrest 7 is for this purpose advantageously compared to the base element 3 slidable to a head 5 the user 6 to be adapted. Alternatively, the headrest 7 independent of the base element 3 on the backrest 4 attached.

The basic element 3 extends annularly above the head 5 the user 6 , Thus, a view of the user 6 not limited to the top, since this due to the ring shape of the base element 3 continues to have an upward view. At the same time is the base element 3 above the user 6 so that a comprehensive action of a functional element of the base element 3 on the user 6 is possible. Such a functional element is advantageously air cushion 8th . 9 acting as a restraint for the user 6 serve.

Particularly advantageous are a first air cushion 8th and a second air cushion 9 present, each of which is inflatable independently. It is both the first air cushion 8th as well as the second air cushion 9 in the base element 3 arranged. A deployment process of the first airbag 8th and the second airbag 9 is in the 3a to 3f shown. In this case, the unfolding process is based on the completely folded state in 3a to the fully unfolded state, that is, the fully inflated state, in 3f shown. Thus, the show 3b to 3e a partially unfolded state of the first airbag 8th and the second airbag 9 ,

It can be seen that due to the annular extension of the base member 3 an inflation path, both the first air cushion 8th as well as the second air cushion 9 from the fully folded state to the fully expanded state, very small. Thus, a quick and immediate inflation of both the first air cushion 8th as well as the second air cushion 9 allows. The user 6 of the vehicle seat 2 is characterized by the first air cushion 8th and the second air cushion 9 safe and reliable in the seat 2 rear durable.

The first air cushion 8th preferably occurs from a bottom of the base member 3 out. The first air cushion 8th is for the retention of the head 5 the user 6 educated. On the other hand, the second air cushion occurs 9 from an upper side of the base element 3 out. The second air cushion 9 serves to restrain the upper body 10 the user 6 , Due to the ring shape of the base element 3 results in a tube shape for the first air cushion 8th and the second air cushion 9 , Thus surrounds the second air cushion 9 the first air cushion 8th in the fully inflated position, that is, in the fully deployed state, at least in part. Advantageously, it is provided that the first air cushion 8th the head 5 and the second air cushion 9 the torso 10 touched in the fully inflated position. Thus, the user 6 safe and reliable in the vehicle seat 2 rear durable.

In order to absorb restraining forces becomes a portion of the first air cushion 8th from a first holding element 11 held while a portion of the second air cushion 9 from a second holding element 12 is held. The first holding element 11 and the second holding element 12 are preferably formed band-shaped. In this way are of the first holding element 11 and the second holding element 12 Tensile forces can be absorbed. About the first holding element 11 is the partial area of the first air cushion 8th with the base element 3 connected. Likewise, via the second retaining element 12 the portion of the second air cushion 9 with the base element 3 connected. Together with the first air cushion 8th and the second air cushion 9 take over the first holding element 11 and the second holding element 12 thus the function of the safety belt 21 , The safety belt 21 itself is not mandatory to the user 6 in the seat 2 restrain. In this way, the vehicle seat offers 2 a comprehensive security for the user 6 when the vehicle seat 2 used in a crash case in a vehicle.

Because the corona 1 firmly with the backrest 4 of the vehicle seat 2 is connected, is the effect of the first air cushion 8th and the second airbag 9 regardless of a current orientation of the vehicle seat 2 in a vehicle. Thus, the vehicle seat 2 especially suitable for self-propelled vehicles in which a vehicle seat 2 does not necessarily have to point in the direction of travel. Rather, an alignment with any angle of the vehicle seat 2 to the direction of travel possible.

4 schematically shows the vehicle seat 2 with a variety of different functional elements. The functional elements are on or in the base element 3 arranged. Thus, the functional elements comprise the first air cushion described above 8th and second air cushions 9 that are in a folded state within the base element 3 are arranged.

In addition, the functional element comprises an air conditioning element 15 , The air conditioning element 15 is also disposed within the base member and is used for air conditioning at least the head 5 and the upper body 10 the user 6 , For this purpose, the air conditioning element 15 at least one, in particular adjustable, nozzle 20 on. The nozzle 20 is on the base element 3 arranged and serves to direct an air flow, which may be optionally heated or cooled, to the user 6 , Thus, there is always an air flow to the user 6 conductive, wherein the air flow regardless of an orientation of the vehicle seat 2 on the user 6 is directed. Thus, a one-time set air conditioning for the user 6 always present, regardless of whether the user 6 the orientation of his vehicle seat 2 adjusted. Through the ring shape of the base element 3 the heated or cooled air is optimal to the user 6 conductive, especially from different directions.

The functional element advantageously also comprises a loudspeaker system 19 , The speaker system 19 is also inside the base element 3 arranged. The speaker system 19 is used for sonicating the user 16 , As the base element 3 ring above the head 5 the user 6 can extend through the Speaker System 19 the impression of a spatial sound for the user 6 be generated. Again, this is the individual sonication of the user 6 regardless of an orientation of the vehicle seat 2 ,

The functional element further advantageously comprises a light element 17 as well as a reading light 18 , The light element 17 is via a support arm 22 with the base element 3 connected and used for large-scale lighting of the user 6 , This means that the light element 17 advantageously by the ring shape of the base element 3 shines through. Thus arises for the user 6 the impression of an artificial sun. The reading light 18 on the other hand, it is designed for focused illumination of a limited area. Thus, it is the reading light 18 a light spot. The focused lighting is a lighting of the environment of the vehicle seat 2 avoided leaving other users, the vehicle seats 2 in an environment of the vehicle seat 2 use, do not be disturbed.

Finally, the functional element advantageously has a spectacle element 16 on. The spectacle element 16 is advantageously from the base element 3 foldout. Alternatively, the base element 3 as a carrier element for the spectacle element 16 formed, wherein the spectacle element 16 foldable against the base element 3 is trained. In this way, the spectacle element 16 in a field of view of the user 6 pivotable. This causes the user 6 Objects are displayed.

5 shows the vehicle seat 2 with the corona 1 according to the embodiment of the invention, wherein the spectacle element 16 in the field of view of the user 6 is pivoted. The spectacle element 16 can be transparent, allowing the user 6 of the vehicle seat 2 can always recognize the environment in real life. About the spectacle element 16 Objects can be overlaid with the environment to the user 6 show additional information. Such information may preferably be directional details of a navigation system which are superimposed with the environment, thus to the user 6 which in this case is preferably a driver of the vehicle in which the vehicle seat 2 is arranged to optimally support in the routing.

Alternatively, the spectacle element 16 not be transparent. Thus, the user stands 6 the opportunity to watch movies or pictures for entertainment. Likewise possible is the environment of the user 6 by means of a camera to this environment, advantageously together with superposed objects as described above, in the spectacle element 16 display.

In the described embodiment, the corona 1 , in particular the base element 3 , arranged annularly and has an oval shape. This ensures that the functional elements are safe and reliable to the user 6 can act. To achieve this at all times, it is also provided that the backrest 4 the upper body 10 the user 6 always follows. Once a contact pressure of the upper body 10 the user 6 on the backrest 4 falls below a predefined minimum contact pressure, it can be assumed that the user 6 from the backrest 4 bends away. However, this causes the base element 3 may no longer be above the head 5 the user 6 is appropriate. Thus, the functional elements can no longer act as intended. Therefore, the backrest follows 4 the upper body 10 the user 6 , so that always the minimum contact pressure is exceeded. In this way it is ensured that the base element 3 always above the head 5 the user 6 is arranged.

The previously described consequences of the backrest 4 of the vehicle seat 2 is suppressed in particular when a vehicle door is open. In this case, the vehicle seat gets 2 prefers a corresponding signal, so that it can be assumed that the user 6 of the vehicle seat 2 want to leave the vehicle. In this case, no consequences of the backrest 4 instead of.

To get in and out of the user 6 It is also intended that the base element 3 opposite the backrest 4 hinged, in particular pivotable about a transverse axis of the vehicle seat 2 , is trained. Thus, the base element 3 be flipped up to the user 6 more space to get in and out of the car seat 2 to give equipped vehicle. This means that the user 6 more room to get out of the vehicle seat 2 raise and get on the vehicle seat 2 is available. A collision of a body part of the user 6 with the corona 1 is thus prevented. The flaps of the base element 3 can preferably be via a drive, in particular automatically.

The above-described comfort functions by the spectacle element 16 , the lighting element 17 , the reading light 18 , the speaker system 19 and / or the air conditioning element 15 can be achieved, can be advantageously expand arbitrarily. So it is possible in particular that by means of the speaker system 19 an active suppression of noise from the environment of the vehicle seat 2 he follows. Likewise, by means of the spectacle element 16 a darkening can be provided to the user 6 to allow a sleep even in daylight.

Furthermore, safety functions are directly by the vehicle seat 2 provided. Thus, these safety functions can be omitted on the vehicle itself. Does a vehicle a vehicle seat 2 As described above, in particular air cushions in the vehicle itself can be omitted. Thus, it is common in the art that air cushions are mounted in columns of the vehicle in order to be able to retain the head of a user of the vehicle. Such airbags are in the use of the vehicle seat 2 as previously described, not necessary.

6 shows an alternative embodiment of the vehicle seat 2 with the corona 1 , In this case, a single difference from the exemplary embodiment described above can be seen in that the base element 3 a first ring segment-shaped element 13 and a second ring segment-shaped element 14. The first ring segment-shaped element 13 and the second ring segment-shaped element 14 are on the backrest 4 appropriate. In this case, form the first ring segment-shaped element 13 and the second ring segment-shaped element 14 the basic element 3 that forms a ring segment above the head 5 the user 6 extends. The first ring segment-shaped element 13 and the second ring segment-shaped element 14 advantageously do not touch each other. In this way, there is an opening in one relative to the user 6 front area of the base element 3 available. Although this has an influence on the shape of the previously described airbags 8th . 9 but not on the functioning of the previously described comfort functions and / or safety functions of the functional element of the corona 1 , Thus, it is not mandatory that the base element 3 must have a closed annular structure.
