Description

The invention relates to an airbag cover according to the preamble of claim 1 and an airbag arrangement according to claim 13 and a steering device according to claim 14. The invention also relates to a method for producing an airbag cover.

Gas bag modules, which are also known under the term airbag modules, are installed in motor vehicles, for example in motor vehicle steering wheels, in order to protect the vehicle occupants in the event of a motor vehicle collision. Gas bag modules generally have a gas bag, a gas generator and a gas bag cover with a tear-off edge, which is intended to ensure the defined tearing open of the gas bag cover when the gas bag module is triggered, in order to unfold the gas bag into the passenger compartment. It is desirable here for the tear-off edge of the gas bag cover not to be visible to the vehicle occupant.

This is solved by a gas bag cover according to claim 1.

Gas bag cover, in particular for a motor vehicle gas bag arrangement, with a cover which is suitable for covering a gas bag at least partially towards a passenger compartment, at least one decorative and/or functional layer, and at least one carrier which has the at least one decorative and/or functional layer connects to the cover, wherein the cover has at least one tear edge (eg, a tear line or tear area). The at least one carrier is connected to the cover, in particular at at least two connection points.

By separating the at least one decorative and/or functional layer from the cover by means of the at least one carrier, a (sensitive) decorative and/or functional layer can be protected from, for example, thermal or chemical influences in the process of connecting the cover and carrier.

The at least one carrier has at least one non-detachable connection point and at least one detachable connection point with the cover.

The at least one non-detachable connection point is designed in such a way that the wearer remains connected to the cover at the at least one non-detachable connection point during and after deployment of the gas bag. The detachable connection point is designed in such a way that the carrier detaches from the cover at the at least one detachable connection point during the deployment of the gas bag.

A decorative layer is understood to mean, for example, a layer which has at least one graphic representation. A graphic representation can be, for example, lettering, a company logo, a number, a letter, a symbol, a pattern, a pictogram and/or an image. A decorative layer can be, for example, a layer of wood, imitation wood, a colored or black plastic layer.

A functional layer can be a layer, for example, which enables information to be reproduced and/or commands to be entered. The functional layer can have or consist of a sensor layer, a display and/or touch screen, for example.

The cover has a top and a bottom. The upper side of the cover is thus understood to mean the side of the cover that is connected to the at least one carrier. The underside of the cover is understood to mean the side of the cover that is opposite the top side of the cover (and points in the direction of the gas bag).

The cover has (at least) one cover part which can be moved by unfolding the gas bag and detaches in sections from the remaining cover part (ie the frame area of the cover) during the unfolding of the gas bag. The cover part that is moved out or movable in the direction of the vehicle occupant by unfolding the gas bag remains connected to the remaining cover part (ie the frame area of the cover) via the connection area even after the gas bag has been unfolded.

The (at least one) carrier has a top and a bottom. The upper side of the carrier is understood to mean the side of the carrier that is connected to the at least one decorative and/or functional layer. The underside of the carrier is understood to mean the side of the carrier which is connected to the cover and which is opposite the upper side of the carrier.

The (at least) one decorative and/or functional layer has an upper side and an underside. The underside of the decorative and/or functional layer is understood to mean the side of the decorative and/or functional layer that is connected to the carrier. The upper side of the decorative and/or functional layer is understood to mean the side of the decorative and/or functional layer that is opposite the underside (and in the direction of the vehicle occupant displays). The (at least) one decorative and/or functional layer can have one edge or multiple edges.

A tearing edge is a weakening, e.g. in the form of a continuous or broken line in the cover, which is intended to ensure the defined tearing open of the cover when the airbag is deployed, e.g. due to a vehicle accident.

The tear edge can be arranged on the top and/or bottom of the cover.

The tear-off edge of the cover can be decoupled (optically) from the decorative and/or functional layer by the carrier, which is arranged between the at least one decorative and/or functional layer and the cover. This provides a flawless and homogeneous surface of the upper side of the decorative and/or functional layer and a tear edge that is invisible to the vehicle occupant.

In the area of the movable cover part, the carrier is connected to the cover via the at least one non-detachable connection point. In the area of the remaining cover, the carrier is connected to the cover via the at least one detachable connection point.

Due to the at least one non-detachable connection point of the carrier with the movable cover part of the cover, the at least one carrier together with the at least decorative and/or functional layer can also remain connected to the remaining cover part of the cover after deployment of the gas bag.

A non-detachable connection point can be, for example, a non-detachable (materially bonded and/or form-fitting) connection by unfolding the gas bag. The non-detachable connection (point) is in particular a material connection. Such a non-detachable connection (point) can be, for example, a welded connection or an adhesive connection, which cannot be overcome by unfolding the gas bag.

The at least one non-detachable connection point between (the underside of) the carrier and (the top of the) cover can be, for example, wavy or straight or have a honeycomb structure or dotted structure.

A releasable connection point can be, for example, a (materially bonded and/or form-fitting) connection that can be released by unfolding the gas bag. A detachable connection can be, for example, a welded connection or an adhesive connection, which is released by unfolding the gas bag.

The releasable connection point between (the underside of the) carrier and (the top of the) cover can, for example, be formed at certain points, e.g. in the form of circles, rectangles or triangles.

A detachable or non-detachable connection (point) between (the underside of the) carrier and (the top of the) cover can be controlled, for example, over the entire area of the connection points. The total area of the permanent connection point or points (in the area of the movable cover part) can be larger than the total area of the releasable connection point or points (in the rest of the cover part). As a result, a detachable and non-detachable connection can be achieved, for example, with the same connection technology. The total area of permanent connections is the sum of the individual connection areas between the bottom of the carrier and the top of the cover of all permanent connections. The total area of the releasable joints is the sum of the individual connection areas between the underside of the carrier and the top of the cover of all the releasable joints.

Since the at least one detachable connection point and the at least one non-detachable connection point are arranged on the underside of the at least one carrier, they are (optically) decoupled from the visible top side of the at least one decorative and/or functional layer.

The at least one decorative and/or functional layer can be connected to the at least one carrier by means of a detachable connection. The at least one decorative and/or functional layer is thus interchangeable. This offers the advantage that, for example, the design, the look, the feel or the function of the at least one decorative and/or functional layer can be changed. For example, the material, the shape, the decor (e.g. the color and/or the pattern) or the type of surface can be changed as desired. The upper side and/or the at least one edge of the at least one decorative and/or functional layer can thus also be designed freely. The safety-relevant cover is therefore not influenced by the individual design.

Due to the modular structure of the airbag cover having the one cover, the at least one carrier and the at least one detachable decorative and/or functional layer, an optimal material can also be chosen independently of the decorative and/or functional layer pairing of cover and carrier, in particular with regard to the method of connecting the cover and carrier.

However, the detachable connection cannot be released by unfolding the gas bag, but only by manual release or with the help of suitable tools, machines or chemical substances.

The detachable connection can be an integral and/or form-fitting connection. Magnetic or mechanical connections are also conceivable. The detachable connection is in particular an integral connection. The detachable connection can be, for example, an adhesive connection, e.g.

The at least one detachable connection of the at least decorative and/or functional layer to the carrier means that the at least decorative and/or functional layer remains connected to the moved out or movable cover part during or after deployment of the gas bag.

Since the detachable connection is arranged in particular on the underside of the at least one decorative and/or functional layer, it is not visible to a vehicle occupant, for example.

The cover can have at least one tear edge. The tear-off edge can be partially interrupted, ie have at least one interruption. The tearing edge can be, for example, a tearing edge that runs almost all the way round and only has an interruption in the tearing edge. This break in the tear edge can serve as a connection area for the movable cover part and the rest of the cover part.

The tear edge can be in the form of a perforated line, for example. Such a perforated tear-off edge has a plurality of tear-off edge sections, which are each separated from one another by a tear-off edge opening, and also has (at least) one interruption that serves as a connecting area of the cover parts during and after deployment of the gas bag.

An interruption can be 2 cm to 10 cm long, for example. An interruption of 2 cm to 10 cm in the tear-off edge makes it possible for the cover parts that are created (movable cover part and the remaining cover part) to remain connected to one another in the connection area when the gas bag is unfolded. As a result, the movable cover part with the at least one carrier and the at least decorative and/or functional layer can fold open like a hinge along the connection area.

For example, the tear edge can represent a material recess, e.g. a depression or an opening in the cover. The indentation can be, for example, an indentation of 0.1 mm to 2.7 mm in the cover. The cover can have a thickness of 3.0 mm, for example.

The at least one carrier and the at least one decorative and/or functional layer do not have a tear edge, for example.

The area between two tear edges is understood as a movable cover part or hinge area. In the case of an almost completely circumferential tear-off edge, the area within the tear-off edge can be referred to as a movable cover part or hinge area.

The area surrounding the movable cover part is also referred to as the remaining cover part or frame area. In the case of an almost completely circumferential tear-off edge, the area outside the almost circumferential tear-off edge is referred to as the remaining cover part or frame area. The remaining part of the cover is thus the area of the cover which remains almost undamaged after the gas bag has been deployed.

The at least one carrier is connected to the movable cover part by means of at least one non-detachable connection point.

During and after deployment of the gas bag, the wearer remains connected to the rest of the cover part of the cover in the area of the movable cover part of the cover via the at least one non-detachable connection point.

The at least one carrier and the at least decorative and/or functional layer covers the tear edge of the cover, for example by at least 1 mm, in the direction of an outer edge of the cover. As a result, the tear-off edge (by a vehicle occupant) is not visible. The area of the carrier that covers the tear-off edge in the direction of an outer edge of the cover is therefore connected to the remaining cover part of the cover via at least one detachable connection point.

A decorative and/or functional layer can have an angular (triangular, rectangular, square, etc.), circular or oval shape.

The upper side and/or the edge(s) of the at least one decorative and/or functional layer can be designed as a high-gloss surface. A high-gloss surface is a surface with a gloss of > 70 GU (gloss units) according to DIN EN ISO 2813:2015-06.

The at least one decorative and/or functional layer can have one, two or more layers. The at least one decorative and/or functional layer can contain a plastic (e.g. polymer), a metal (e.g. aluminum), an alloy, a paint, wood, glass, a textile, leather or imitation leather or a combination of these or exclusively from the individual materials consist. The at least one decorative and/or functional layer can contain or consist of at least one thermoplastic elastomer, for example. Alternatively or additionally, the at least one decorative and/or functional layer can have at least one lacquer layer and/or aluminum layer, for example. The lacquer layer can be a piano lacquer layer, for example. A single-layer decorative and/or functional layer can also be formed from a thermoplastic elastomer, for example.

A two-layer decorative and/or functional layer can have, for example, a layer of a thermoplastic elastomer and a layer of lacquer. Alternatively, a two-layer decorative and/or functional layer can have a layer of a thermoplastic elastomer and an aluminum layer. A two-layer or multi-layer decorative and/or functional layer can have, for example, at least one aluminum layer and at least one anodized layer (having an aluminum oxide layer) and/or at least one lacquer layer. A three-layer or multi-layer decorative and/or functional layer can have, for example, at least one aluminum layer and/or at least one lacquer layer and/or at least one thermoplastic elastomer layer.

The at least one decorative and/or functional layer can have a layer thickness of 0.1 mm to 1.0 cm or 0.1 mm to 3.0 mm or 0.5 mm to 5.0 mm or 1.0 mm to 3 0mm. The at least one decorative and/or functional layer can be a plate with a layer thickness of 1.0 mm to 3.0 mm, for example. The at least one decorative and/or functional layer can contain, for example, a lacquer layer with a layer thickness of 10 μm to 500 μm.

The at least one carrier can be formed from at least one plastic (e.g. polymer), in particular from at least one thermoplastic elastomer, or can contain this.

The at least one carrier can be designed as a continuous layer, for example. There may also be two or more than two supports arranged (side by side) on top of the cover.

The at least one carrier can be designed, for example, as a wavy line, zigzag line, curved or straight line or have a honeycomb structure or dotted structure.

The carrier has, for example, a layer thickness of 0.5 mm to 4.0 mm or 0.5 mm to 3.0 mm or 1.0 to 4.0 mm or 2.0 mm to 3.0 mm.

The cover can be formed from at least one plastic (e.g. polymer), in particular from at least one thermoplastic elastomer (TPE). The cover may be formed from or include, for example, an olefin-based thermoplastic elastomer (TPO) or a thermoplastic styrenic block copolymer (TBS).

The covering can have a layer thickness of 1.0 mm to 4.5 mm or 2.0 mm to 4.0 mm.

In an exemplary configuration, the at least one decorative and/or functional layer can contain an aluminum layer and a lacquer layer, in particular piano lacquer layer, and the cover and the at least one carrier can be formed from a thermoplastic material, in particular TPO. The lacquer layer can have a layer thickness of 10 μm to 500 μm, the decorative and/or functional layer can have a layer thickness of 0.1 mm to 3.0 mm, the at least one carrier can have a layer thickness of 0.5 mm to 4.0 mm and the cover has a layer thickness of 1.0 mm to 4.5 mm.

The sum of the layer thicknesses of the cover, the at least one carrier and the at least one decorative and/or functional layer results in a total layer thickness of the gas bag arrangement of 1.0 mm to 8.0 mm or 2.0 mm to 8.0 mm or more 3.0 mm or 4.0 mm but less than 2.0 cm.

The sum of the layer thicknesses of the carrier and the decorative and/or functional layer results, for example, in a layer thickness of 0.6 mm to 7.0 mm or 1.0 to 7.0 mm or 2.0 to 7.0 mm or 3.5 mm to 7.0mm.

The mass (in grams) of the cover part that can be moved (out) by unfolding the gas bag together with the mass (in grams) of the at least one carrier and the at least one decorative and/or functional layer is in relation to the cross-sectional area (in mm ² ) of the Connection area of the cover, which does not fall below the ratio of 5, for example. For example, the ratio of cross-sectional area (mm ² ) to mass (g) is 5:1. As a result, the movable cover part is reliably moved out (hinged) when the airbag is deployed.

The cross-sectional area of the connection area (of the cover part that occurs after the gas bag is unfolded) is, for example, 100 mm ² to 1000 mm ² .

The mass of the cover part that can be moved by unfolding the gas bag together with the mass of the at least one carrier and the at least one decorative and/or functional layer is, for example, 20 g to 200 g.

• - und (anschließendem) Aufbringen mindestens einer Dekor- und/oder Funktionsschicht auf die Oberseite des Trägers mittels einer ablösbaren Verbindung.

A method for producing an aforementioned gas bag cover is also described, which comprises the following steps:

• - providing a cover with a top and bottom and
• - Applying a support to the top of the cover by means of at least one non-detachable connection and by means of at least one detachable connection
• - and (subsequently) applying at least one decorative and/or functional layer to the upper side of the carrier by means of a detachable connection.

The application of the carrier and the application of the at least one decorative and/or functional layer can be applied by means of an adhesive connection and/or a welded connection.

By applying the at least one decorative and/or functional layer to the cover by means of the at least one carrier, a (sensitive) decorative and/or functional layer can be protected from damage by thermal or chemical bonding methods of cover and carrier.

The carrier can be applied to the upper side of the cover in such a way that the carrier is connected to a movable cover part of the cover via the at least one non-detachable connection point and the carrier is connected to a remaining cover part of the cover via the at least one detachable connection point. The total area of the non-detachable connection point or points can be larger than the total area of the detachable connection point.

The aforementioned features for the airbag cover, in particular with regard to the connection(s), the layer thicknesses or the material of the cover, the at least one carrier and/or the at least one decorative and/or functional layer are hereby also described as process features.

Furthermore, an airbag arrangement with an inflatable airbag (to protect a vehicle occupant) and an aforementioned airbag cover is described. The gas bag cover is suitable for covering the gas bag at least partially towards the passenger compartment. The gas bag arrangement can also have a gas generator.

In addition, a steering device with the aforementioned airbag cover or airbag arrangement is described. The steering device comprises, for example, an inflatable gas bag, a gas bag cover according to the invention with a cover, at least one carrier and at least one decorative and/or functional layer and at least one steering element segment, for example a steering wheel rim. The gas bag cover covers the gas bag at least partially from the passenger compartment. For example, the at least one carrier and/or the at least one decorative and/or functional layer is not connected to the at least one steering element segment.

A motorized vehicle is also described which has at least one of the aforementioned airbag covers. The motorized vehicle can be, for example, an electrically powered vehicle and/or a partially or fully autonomous vehicle (e.g. a car).

1A FIG. 1 shows a gas bag cover with a cover 4, a decorative and/or functional layer 2 and a non-visible carrier 3, indicated by a dashed line, which connects the decorative and/or functional layer 2 to the cover 4.

1 B shows an exploded drawing of the gas bag cover 1 1A . The cover 4 has an upper side 41 and an underside 42 . The carrier 3 also has an upper side 31 and an underside 32 . The decorative and/or functional layer 2 also has an upper side 21 and an underside 22 . The top 41 of the cover 4 is connected to the bottom 32 of the carrier 3 . The underside 42 of the cover 4 would point in the direction of the gas bag in a gas bag arrangement (not shown here) comprising at least the gas bag cover, a gas bag and a gas generator. The top 31 of the carrier 3 is connected to the at least one decorative and/or functional layer 2 .

The cover 4 has a tear edge 7 which has an interruption. Here the tear edge 7 is shown, for example, as a perforated line comprising a plurality of tear edge sections 71 which are separated from one another by tear edge openings 72 . The area of the cover 4 within the almost circumferential tear-off edge 7 represents a movable cover part 5 which, not shown, is detached in sections when the airbag is deployed, but remains connected to the remaining cover part 6 in a connection area 8 . The interruption of the tear-off edge 7 forms the connection area 8 of the cover parts created by unfolding the gas bag.

In 2A a cover 4 is shown with a tear edge 7 which has an interruption and a plurality of tear edge sections 71 . The cover 4 has a tear-off edge 7 running almost all the way round, with the area of the cover inside the tear-off edge 7 representing the movable cover part 5 . The area surrounding the tear-off edge 7, ie the area surrounding the movable cover part 5, represents the remaining cover part 6. The tear-off edge 7 is arranged here on the upper side of the cover 4 and is designed as a material recess in the form of a material recess.

2 B FIG. 12 shows a plan view of the cover from FIG 1A with a carrier 3. To better illustrate the connection points and the tear-off edge, the decorative and/or functional layer 2 is shown transparent, which does not mean that it actually has to be transparent.

The carrier 3 here has a number of detachable connection points 9 and a number of non-detachable connection points 10 with the cover 4 . The non-detachable connection points 9 are designed in such a way that the carrier 3 remains connected to the cover 4 at the non-detachable connection points 10 while the gas bag 11 is deployed. For this purpose, the non-detachable connection points 10 are designed, for example, in a honeycomb structure. The detachable connection points 9 are designed in such a way that the carrier 3 detaches from the cover 4 at the detachable connection points 9 during the deployment of the gas bag 11 . For this purpose, the detachable connection points 9 are configured in a point-like manner, for example. The total area of the non-detachable connection points 10 is, for example, larger than the total area of the detachable connection points 9. As a result, a detachable and non-detachable connection can be achieved, for example, with the same connection technology. The non-detachable connection points 10 are arranged in the area of the movable cover part 5, here inside the tear-off edge 7. The detachable connection points 9 are arranged in the remaining cover part 6, the frame area, here outside the tear-open edge 7.

the 3A until 3D show a steering device 13 with an airbag arrangement 12, comprising an airbag cover 1 with a cover 4 and a decorative and/or functional layer 2 and a carrier 3. The steering device 13 comprises at least one steering element segment 14, for example in the form of a steering wheel rim.

3A shows a steering device 13 with an airbag arrangement 12 before the airbag is unfolded (not visible). the 3B until 3D show a steering device 13 during the deployment of the gas bag 11 over time. The steering device 13 comprises at least one steering element segment 14, for example in the form of a steering wheel rim.

Before the gas bag 11 is unfolded, the support 3 with the decorative and/or functional layer 2 is also connected to the cover 4 via the at least one detachable connection point and the at least one non-detachable connection point (not visible), see 3A .

During the deployment of the gas bag 11, the movable cover part 5 through the unfolding gas bag 11 in the direction of the vehicle occupant partially detached from the rest of the cover 6 along the tear-off edge 7. In this case, however, the movable cover part 5 remains connected in the connection area 8 to the remaining cover part 6, ie to the frame area. The detachable connection by means of which the decorative and/or functional layer 2 is connected to the carrier 3 cannot be detached by unfolding the gas bag 11 . As a result, the movable cover part 5 with the carrier 3 and the decorative and/or functional layer 2 can fold open along the connection area 8 like a hinge.
