Restraint device, restraint arrangement and seating unit

Description

[0001] The invention relates to a seat unit comprising a vehicle seat and a restraining device according to the preamble of claim 1.

[0002] An advanced restraining device - and thus a restraining assembly and a seat unit - is known from EP 3 527 440 B1. In this document an airbag cushion is described that extends adjacent or partially over the shoulder of the occupant sitting in the vehicle seat. The deployed airbag cushion is held by a belt such that this airbag cushion can restrain the occupant without the need of a supporting surface (for example an instrument panel) like traditional frontal airbag cushions need.

[0003] Generic US 2019 / 283700 A1, that corresponds to the preamble of claim 1, shows a restraining device having an airbag with several sections and tethers for restraining those sections. In one embodiment shown in this document, the airbag has a section at the side of the passenger, a section that extends essentially over the shoulder of the passenger and a section being located in front of the passenger.

[0004] Starting from this prior art it is an object of the invention to provide a seat unit which gives an even enhanced level of protection in a variety of accident scenarios.

[0005] This task is solved by a seat unit having the features of claim 1.

[0006] The restraining device of the seat unit comprises an airbag cushion having a first part which extends over the shoulder of the occupant at least when this first part is in its deployed state. This first part has a backrest-proximate first end. From this first end the first part extends to a second end being in a first direction remote from the first end.

[0007] Further, the airbag cushion additionally comprises a second part and a third part, wherein the second part extends laterally from the occupant, such that it has at least an upper section being located laterally from the occupant's head and the third part is located in front of the occupant, when the airbag cushion is deployed.

[0008] Consequently, the deployed airbag cushion has the following structure: The first part extends from its first end in a first direction to second end and extends in a second direction from a third end to a fourth end. The second part which is connected to the first part extends in a third direction from a fifth end to a sixth end and from a seventh end to an eighth end, such that at least an upper section of the second part extends laterally of the person's head. The third part extends in the second direction from a ninth end to a tenth end.

[0009] In the mounted state, the restraining device is attached to a vehicle seat in such a way that the second part is attached to the backrest at least indirectly, usually in the manner of a traditional side airbag. An inflator is in fluid communication with the second part of the airbag cushion such that the restraining device and the inflator form a restraining assembly. The assembly comprising the vehicle seat and the restraining assembly is called seat unit.

[0010] Each of the parts is connected to each of the other parts, such that the deployed airbag cushion has a self-supporting, three-dimensional structure.

[0011] According to the invention, the restraining device additionally comprises a first belt for positioning the deployed airbag cushion relative to the vehicle seat even when an external force (usually exerted by the occupant) is applied to the airbag cushion, especially to its third part. This enhances the self-supporting abilities of the restraining device and especially makes it independent from a supporting surface in front of the third part, such that it can restrain the person without the need of a support by the vehicle structure. This can especially be relevant (but not only) for self-driving cars with flexible sea arrangements.

[0012] This first belt extends from the backrest to the seating of the vehicle seat and through the airbag cushion, namely through a first tunnel in the third part. This leads to a very effective positioning and restraining of the airbag cushion by the first belt.

[0013] Preferably, the eighth end of the second part and the ninth end of the third part are connected to one another at least indirectly and at least in sections, such that the projection of these parts in the third direction is essentially L-shaped. This shape usually perfectly fits into a vehicle and additionally it eases the production.

[0014] It is often preferred that the second part forms a "full" side airbag, meaning that it protects not only the head but also at least a part of the occupant's torso. In this case the second part extends from the third end of the first part in the third direction (Z-direction) to both sides of the first part such that it comprises the upper section extending laterally of the person's head and a lower section extending laterally of the person's torso.

[0015] Even more preferred, the restraining device comprises a second belt extending along a person-remote surface area of the airbag cushion, especially along a person-outer surface of the second part. In this case, the restraining device can be completely independent from supporting surfaces. Since the second part extends up to the occupant's head, also the second belt can extend through a tunnel, namely a second tunnel in the second part. Alternatively the second belt can extend over the sixth end of the second part.

[0016] In order to make sure that the belt(s) cannot come into direct contact with occupant's neck, it / they is / are preferably connected to the first part, for example by means of a load bearing patch, wherein it is preferred that the belt(s) cannot slide in this load bearing patch.

[0017] In order to better restrain the occupant's chest, the first part may widen towards its second end, such that its fourth end comprises a concave surface area.

[0018] Preferably, the airbag cushion is filled with gas via the second part, especially in a traditional "side airbag way", meaning that the inflator is located inside the second part near the seventh end of the second part. An assembly comprising the restraining device and the inflator is called "restraining assembly".

[0019] In a preferred embodiment of the restraining assembly, the second part comprises an outer skin and a flexible shaping element being located inside the outer skin at the seventh end of the second part. This shaping element has an inner first section and this shaping element is attached to the outer skin via at least two connection sections in such a way that at least a section of the inflator is circumferentially encircled by the outer skin and the first section of the shaping element in such a way that the inflator is encircled by the outer skin in an angle between 20° and 340°, preferably in an angle between 45° and 340°, and even more preferably in an angle between 180° and 300°. By this means the dimensions of the deployed outer skin can be reduced in the region of the inflator, where large dimensions are unnecessary or even disadvantageous.

[0020] The shaping element can be tube-shaped such that it additionally comprises a second section extending along the outer skin of the second part. This can ease the production since the positioning of the shaping element is made easy and additionally a protection layer for the outer skin is provided. In this configuration, the connection sections can be parts of a closed connection such that the second section of the tube-shaped shaping element is located inside the closed connection. By this measure, the forces occurring when the inflator is exhausting gas can be distributed over a larger area.

[0021] It needs to be mentioned that the use of such an inventive shaping element as described above is not limited to a restraining assembly as claimed in this application, but can also be applied to over kinds of airbag assemblies comprising an inflator being located inside an airbag cushion, especially to side airbag assemblies in which the inflator is located proximate the rear end of the airbag cushion.

[0022] Such a seat unit can comprise two restraining assemblies, namely a first restraining assembly whose first part of its airbag cushion extends over the left shoulder of the person and a second restraining assembly whose first part of its airbag cushion extends over the right shoulder of the person, such that the occupant is protected from all sides.

[0023] In order to prevent the occupant from slipping through the two airbag cushions in case of a pure frontal accident, it can be preferred that the two airbag cushions are asymmetric in respect to each other.

[0024] The invention will now be described in more detail by means of preferred embodiments in view of the figures. The figures show: Figure 1a schematic side view onto a seat unit comprising a vehicle seat and a restraining assembly according to a first embodiment of the invention, wherein a person is seated in the vehicle seat and wherein the airbag cushion of the restraining assembly is in its un-deployed resting state, Figure 2the item shown in Figure 1, wherein the airbag cushion is in its fully deployed state, Figure 3a top view to what is shown in Figure 2 (viewed from direction R1 in Figure 2), Figure 4a strictly schematic front view onto the restraining device of the restraining assembly of Figures 2 and 3 from the front from direction R2 in Figure 2, but with the seat and the person not being shown, Figure 5the detail D of Figure 4, Figure 6essentially the restraining device of Figure 3 in an embodiment that does not correspond to the invention and with some more details and with the seat and the person not being shown, Figure 7a second embodiment that does not correspond to the invention in a representation according to Figure 6, Figure 7aa variation to what is shown in Figure 7, that also does not correspond to the invention, Figure 8a third embodiment of the invention in a representation according to Figure 7, Figure 9a fourth embodiment of the invention in a schematic perspective view, Figure 10the cuttings necessary for forming an airbag cushion as it is for example shown in Figure 6, Figure 11the complete airbag cushion being sewn form the cutting shown in Figure 10 in a view from the side, Figure 12the sectional view taken along line A-A in Figure 11 in the deployed state of the airbag cushion, Figure 13an improved side airbag in a representation according to Figure 12, Figure 13aa variation to what is shown in Figure 13, Figure 14a shaping element being a part of the side airbag shown in Figure 13, Figure 15the shaping element of Figure 14 with the position of a sewing being shown, and Figure 16a variation to what is shown in Figure 13.

[0025] Figures 1 to 5 show a first embodiment of the invention in schematic representations. Figure 1 shows a seat unit being comprised of a vehicle seat 10 and a restraining assembly. According to the definitions chosen in this application, this restraining assembly comprises an airbag cushion 20, an inflator 60 for inflating this airbag cushion 20 and being located inside this airbag cushion 20, and a first belt 71 being attached to both, the vehicle seat 10 and the airbag cushion 20. The airbag cushion and the first belt 71 constitute the restraining device. This restraining device and the inflator constitute the restraining assembly. In Figures 1, 2 and 3 additionally a person P sitting in the vehicle seat 10 is shown, in order to make clear the position of the parts of the airbag cushion 20 relative to this person P when the airbag cushion is deployed.

[0026] As can be seen in Figure 1, the packed airbag cushion 21 is attached to the backrest 14 of the vehicle seat 10 (for example via inflator studs being attached to the frame of the backrest as is known from the prior art). Usually the packed airbag cushion 21 is located inside the backrest 14, meaning inside the upholstery of the backrest 14. The first belt 71 to which a section of the airbag cushion 20 is attached, extends from a first end 71a being attached to the backrest to a second end 71b being attached to the seating 12.

[0027] Figure 2, 3 and 6 show the deployed state of the airbag cushion 20. One can see that this airbag cushion 20 comprises three parts, namely a first part 30, a second part 40 and a third part 50. The first part 30 extends in a first direction (the X-direction) from a first end 30a located next to the backrest 14 of the vehicle seat 10 over the shoulder of the person P to a second end 30b. The term "extending in the X-direction" is not to be understood in such a way that the first part only extends in this direction (indeed it can be tilted or curved relative to this direction), but in any case the first end 30a and the second end 30b have different X-coordinates such that the first end is the backrest-proximate end and the second end is the backrest distal end. The deployed first part further extends in a second direction (Y-direction) from a (occupant distal) third end 30c to a (occupant proximate) fourth end 30d. In the embodiment shown, the fourth end 30d is concave at least in sections. The first part 30 has (of course) an upper surface, to which the first belt 71 is attached.

[0028] The airbag cushion 20 further comprises a second part 40 which essentially forms a side airbag and thus extends in a third direction (Z-direction) from a fifth end (lower end) 40a to a sixth end (upper end) 40b and in the first direction from a seven end (rear end) 40c to an eighth end (forward end) 40d.

[0029] The first part 30 is attached to the second part 40, at least around an overflow which connects the chamber enclosed by the second part with the chamber enclosed by the first part 30. This will be explained in more detail in view of Figure 10.

[0030] In this embodiment, and this is preferred, the second part 40 extends - in the deployed state - in the third direction (Z-direction) from a fourth end, which is located under the first part 30 to a sixth end, which is located above the first part 30. So, this second part 40 comprises an upper section 42 being allocated to the head of the occupant and a lower section 44 being allocated to at least a section of the occupant's torso.

[0031] The third part 50 extends from a ninth end 50a, which essentially coincides with the eighth end 40d of the second part 40, in the second direction (Y-direction) to a tenth end 50b. This third part 50 at least has an upper section being located in front of the occupant's head as can especially be seen from Figure 2. This third part 50 can extend to a lower end being located below the second end 30b of the first part 30, but this is optional. At least a section of the second end 30b of the first part 30 is attached to the impact wall of the third part 50, for example by sewing, gluing, welding or the like. In case that an overflow is present between the first part and the third part, the respective connection can extend around this overflow.

[0032] So, each of the three parts 30, 40, 50 is attached to each of the other parts, such that the deployed airbag cushion 20 forms a three-dimensional, self-supporting structure and especially does not need a restraining surface in front of the occupant, as a traditional front airbag cushion needs. The first belt 71 even enhances this self-supporting ability of the restraining device, as will now be described: As has already been mentioned above, the first end 71a of the first belt 71 is attached to the vehicle seat 10, preferably at an upper end of the backrest 14, and the second end 71b is attached to the lower part of the vehicle seat 10, especially near the front end of the seating 12. The respective attachment to the vehicle seat 10 can take place via brackets 75 being connected to a frame part (not shown in detail). In other embodiments, the at least one of the end sections can be rolled onto a roll, especially a roll of a retractor.

[0033] As can for example be seen from Figure 6, according to an embodiment that does not correspond to the invention, a section of the first belt 71 is attached to a section of the upper surface of the first part 30, for example by means of a load bearing patch 80 and at least on seam, but in principle also a pure direct attachment could be possible. Providing a load bearing patch 80 has the advantage that the relatively high forces that might occur is distributed over a larger area so that especially a tearing of the first part 30 is prevented. A connection of the first belt 71 to the first part 30 is usually necessary in order to prevent the first belt 71 from coming into contact with the occupant's neck which would be a potential threat. According to the invention, the first belt 71 extends through a first tunnel 51 in the third part 50, as can best be seen from Figures 2, 4 and 5. Especially by this feature, but also by the connection to the first part 30, the first belt 71 at least limits a movement of the third part 50 in X-direction when the occupant hits the impact surface of this third part during an accident such that the occupant is restrained.

[0034] Figure 7 shows a second embodiment, that does not correspond to the invention. This embodiment comprises additionally a second belt 72 whose first end 72a is also attached to the backrest 14, preferably at the upper end of the backrest 14; the first belt 71 and the second belt 72 can use the same bracket 75 for this attachment. The second belt 72 is also attached to the upper surface of the first part 30 and a joint load bearing patch 80' can be used for this as it is shown in Figure 7. In contrast to the first belt 71, the second belt 72 does not extend through the first tunnel 51 but through a second tunnel 41 in the second part 40. The second end of the second belt 72 is also attached to the seat, especially in a region of the seating 12, such that a lower section of the second belt 72 extends along the outer surface of the lower section 44 of the second part 40, such that the second belt 72 prevents the airbag cushion and especially its second part 40 from moving in the -Y-direction even if no supporting surface (like an inner structure of the vehicle, for example a door) is provided, such that the occupant is restrained also in this direction. So, in this embodiment the restraining device is fully self-supporting and does not need any supporting surfaces.

[0035] As an alternative, the second belt 72a could extend over the sixth end (top end) 40b of the second part 40, such that a section of the second belt extends along the whole height of the outer wall of this second part 40. This alternative (in a view according to Figure 7) is shown in Figure 7a.

[0036] Figure 8 shows a third embodiment according to the invention in a representation according to Figure 7.

[0037] Here, two restraining assemblies are provided, one on the right side of the vehicle seat and one on the left side of the vehicle seat. In a principle these two restraining devices could be mirror-symmetrical, but it will often be preferred that they are not mirror-symmetrical, especially such that one of the third parts is larger than the other third part, such that the border between those two third parts is offset from the middle axis of the vehicle seat, such that the front restraining function is taken over mainly by one of the two restraining devices, such that the head of the occupant cannot slip through the two third parts.

[0038] As can be seen from Figure 9, such a "doubling" of the restraining devices can also be applied to the case that each restraining device only comprises one belt. Providing one restraining device with one belt and the over restraining device with two belts would of course also be possible.

[0039] Figure 10 shows schematically an example for the cuttings being necessary in order to manufacture the airbag cushion of the second embodiment. In Figure 10 only strictly necessary cuttings are shown, but of course additional cuttings, for example for forming enforcement layers, inner tethers or the like can be used, but since those are not necessary in order to understand the structure, they are not shown. Further, outer tethers or other outer elements could be used, for example in form of at least one sail connecting at least two of the parts in order to provide an additional restraining element. In the embodiment shown, only four cuttings are necessary, namely a first cutting 100 for the first part, a second cutting 110 for the second and the third part, and cuttings 120 for the tunnel walls. Both, the first cutting 100 and the second cutting 110 are of the "butterfly" type, meaning that they are folded along a folding line F1 and F2 respectively. Of course, this invention is not limited to the type of cuttings shown here. For example, each layer could be made from a distinct cutting. Further, providing a joint cutting for layers of the first part and third part is not mandatory.

[0040] The first cutting 100 shows at least one overflow opening 102 (here two overflow openings) and the second cutting 110 shows matching overflow openings 112. Additionally, the second cutting 110 shows two holes 114 for the first tunnel and two holes 115 for the second tunnel. Further, holes 116 for inflator studs are provided as is generally known form side airbags.

[0041] The sewing process could be for example be as follows: First, the first cutting 100 is sewn to the second cutting 110, especially around the overflow openings 102, 112. After this, the first cutting 100 can be folded and closed by an edge seam in order to form the first part. Then, the cuttings 120 for the tunnel walls can be sewn to the edges of their respective holes 114, 115 and then the first part can be sewn to the cutting 110 by means of protruding sections 104 of the first cutting 100. Finally, an edge seam for closing the cutting 110 to form the second part and the third part can be applied. Because the first part is connected to both, the second part and the third part, the third part is automatically bent out of the plane of the second part, such that the completely sewn airbag cushion looks as it is shown in figure 11 in a plane view onto the second part.

[0042] Figure 12 shows a sectional view taken along line A-A in Figure 11 in case that the airbag cushion is fully deployed. One can see a typical side airbag scenario, namely that the outer skin 46 of this side airbag (the second part is a side airbag) deploys beyond the rear end of the inflator 60. Further, one sees that at the position of this inflator 60 the side airbag has a rather large thickness. Both is usually not desired for the following reasons: One reason is that the deployed volume is uselessly large in this region but still needs to be filled so that inflation gas is wasted and a respectively large inflator must be used. Second, especially the part deploying rear of the inflator can interfere with other parts of the vehicle, for example with parts of the vehicle seat or another inner structural part of the vehicle, which is usually not desired.

[0043] Figures 13 to 15 show a possibility of how this extra volume and deployment space can be minimized by using a shaping element 130. In a first - and often preferred - embodiment this shaping element 130 is tubular-shaped and extends around the usually cylinder-shaped inflator 60. It is attached to the outer skin 46 by means of a connection, usually a seam 134. The position of the seam 134 is shown in Figure 15. This connection (seam 134) comprises two sections 134a, 134b extending essentially parallel to the inflator. In the embodiment shown, the connection is closed, but this is not absolutely necessary for the function. It is essential that the connection, or at least its sections 134a, 134b define a first section 130a of the shaping element 130 which is located in the inside of the side airbag cushion, such that a section of the outer skin 46 and this first section 130a encircle the inflator 60. In the first embodiment, in which the shaping element 130 is tubular, the remaining second section 130b extends along the outer skin 46 such that this area is double layered (which can be preferred in order to protect the outer skin 46 from inflation gases).

[0044] So, the inflator 60 is circumferentially encircled by the outer skin 46 and the first section 130a of the shaping element 130, wherein the inflator 60 is encircled by the outer skin 46 in an angle between 20° and 340°, preferably in an angle between 180° and 300° (shown is an angle of approximately 250°). Generally, an angle being 45° or larger is preferred. As can be seen directly by comparing Figures 12 and 13, the deployed outer skin is shortened at its rear end and its thickness is reduced in the region of the rear end.

[0045] In case that the tubular shaping element is made from a flat piece of material, it comprises a closing connection, for example a closing seam 136 which extends essentially parallel to the axial direction of the inflator. This is shown in Figure 13a. In this case it will often be preferred that this closing connection is applied after the (in this stage not yet tubular) shaping element is attached to the outer skin.

[0046] Figure 16 shows an embodiment in which the shaping element 130 exclusively consists of its first section 130, which leads to the same geometry as shown in figure 14, but providing a tubular shaping element 130 will often be preferred, because due to this shaping element some sections of the outer skin 46 are quite close to the inflator and will often need extra protection from the inflation gases.

[0047] As has already been mentioned, the use of such a shaping element is not limited to the claimed restraining assembly but can also be applied to other kind of airbag assemblies, especially side airbag assemblies comprising a side airbag cushion and an inflator.List of reference numbers
