Description

Vehicle assembly

Technical Field

The invention relates to a vehicle component having two components, between which there is at least one intermediate space, in which at least one adhesive layer is arranged, by means of which the components are joined together, and at least one airbag in the uninflated state is arranged in the intermediate space.

Background

If it is desired to push two vehicle parts apart using an airbag, for example to form a soft impact area on the front bonnet for pedestrian protection, and if the vehicle parts are joined together by an adhesive, for example in order to reduce NVH behaviour as much as possible, the load that the airbag must apply to the respective vehicle part in order to push the two bonded parts apart depends on the adhesive and the nature of the bond. The adhesive must meet given requirements for bonding two vehicle components together, which may conflict with the requirement for separating the two vehicle components from each other. In order to reduce the adhesive force with which the vehicle parts are joined together by means of the adhesive, the adhesive can be applied locally to one vehicle part at various locations until a certain point is reached, at which point the adhesive no longer meets the requirements due to reduced adhesion.

DE 10057941 a1 discloses a front engine cover with energy absorption on a vehicle, which has an outer panel and a reinforced substructure, and an airbag arranged between them, which can be filled with gas released by a gas generator and thus deployed to lift the outer panel. The airbag is formed as an airbag hose and is divided into a plurality of airbag segments, or several airbags are arranged next to one another, wherein each airbag segment or airbag can be filled with a gas under the control of a sensor.

GB 2547791a discloses a vehicle bonnet arrangement having an inner bonnet, an outer bonnet fixed relative to the inner bonnet, and a number of deployable devices arranged spaced apart from each other between the inner bonnet and the outer bonnet, wherein each of the deployable devices defines an expansion chamber and is made of a thermoplastic elastomer.

Disclosure of Invention

The invention is based on the object of reducing the force with which an adhesive between two vehicle parts is separated when an airbag is used.

According to the invention, this object is achieved by a vehicle component having the features of claim 1, having at least one linear release element which is partially embedded in the adhesive layer, wherein at least one end of the release element is connected to a part of the airbag by a connecting point.

It is to be noted that the features and measures listed individually in the following description can be combined with one another in any desired, technically expedient manner and disclose further embodiments of the invention. The specification further characterizes and describes the present invention, particularly in conjunction with the accompanying drawings.

According to the invention, upon deployment of the airbag, the linear release element is also moved, whereby the release element is pulled or tensioned and cuts through the adhesive layer, weakening it. Due to this weakening of the adhesive layer, the bond between the two components produced by means of the adhesive layer can be released by a smaller force, since the parts of the adhesive layer adjacent to the weakening points of the adhesive layer produced by the release element can be separated from one another more easily. In order to reliably separate the adhesive layer by means of the airbag, therefore, only a smaller force has to be applied to the two components than would be the case without a correspondingly weakened adhesive layer. In this way, the airbag and associated inflator can be designed to be weaker, which is associated with reduced cost and/or weight.

The airbag may be connected to one of the components. The connection can be achieved by opposing layers, symmetrical bonding or component side bonding. The airbag in the uninflated state can easily be laid flat between the components or folded in a specific manner. The airbag may be placed annularly around the adhesive layer. The gas generator may be attached/mounted in the intermediate space or outside the intermediate space. The airbag can be configured such that its bottom surface projected onto one component is reduced in size by the inflation process, so that the attachment points of the adhesive layer have moved away and thus a tension is exerted on the release element.

The wire-like release member may be configured for a flexible bend. The wire-like release element may for example be a fibre-reinforced, nylon-made, braided or similar wire, cable, wire. The wire-like release element is partially embedded in the adhesive layer such that at least an end portion of the release element is not embedded in the adhesive layer so as to be able to connect at least one end portion to the airbag. The thread-like release element is preferably constructed such that its contact area with the adhesive layer, by means of which the adhesive layer is bonded to one of the components, is very small compared to the bonding area of the adhesive layer. In this way, by embedding the release element in the adhesive layer, the adhesive strength of the adhesive layer is not reduced as much as possible. At least one end of the release element can be connected to the airbag at a corresponding connection point by a substance connection. Alternatively or additionally, at least one end of the release element may be sewn to the airbag at a connection point. The route of the release element through the adhesive layer may be adapted to the respective requirements, in particular in order to be able to cause a certain degree of weakening of the adhesive layer.

The airbag may be attached to one component. The connection point connecting the release element to the airbag may be arranged on a part of the airbag facing away from the part to which the airbag is connected. In this way, this connection point, together with the end of the release element connected thereto, is displaced in the direction of the component which is not connected to the airbag upon deployment of the airbag, so that the release element can be pulled through the adhesive layer, for example in the direction of its length extent or in its transverse direction, in order to cut through the relatively soft adhesive layer. This results in a weakening of the adhesive layer as described above.

Likewise, both ends of the release element may be connected to the airbag via connection points, wherein both connection points may be arranged at one side of the airbag (e.g. the side facing the adhesive layer). Here, the two connection points may be arranged on the airbag such that they separate from one another when the airbag is inflated or deployed, so that the release element moves and cuts through the adhesive layer. Alternatively, the attachment point may be disposed on the airbag such that the attachment point moves away from the adhesive layer upon deployment of the airbag such that the release element moves and cuts through the adhesive layer. The airbag may remain fixed with respect to a plane extending parallel to the components, for example by being bonded to one component or by a wire or by another means of direct connection (for example by being screwed through a seam).

The adhesive layer can resist tensile and compressive loads in the direction of the distance between the two components, but is generally less resistant to shear forces (e.g., cutting forces).

The movement of the release element through the adhesive layer may for example be parallel to the connection plane between the adhesive layer and the respective component, perpendicular to the connection plane or oriented at an angle other than 90 ° to the connection plane.

The components may for example be planar and form the housing of a double-shell vehicle component (e.g. a front bonnet), respectively, which may thus form a vehicle assembly according to the invention.

According to an advantageous embodiment, the other end of the release element is connected to a fixing point on one of the components or to another connection point on another airbag arranged in the intermediate space in the uninflated state, wherein the adhesive layer is arranged at least partially between the airbag and the fixing point or the airbag. Another airbag may be connected to one of the components. In this way, the other end of the release element is held essentially fixedly on a fixed point on one of the components or, when the other airbag is deployed, moves together with the other airbag in the direction of the component which is not connected to the other airbag, wherein the airbags are preferably deployed simultaneously. The adhesive layer may be arranged partially or completely between the airbag and the fixing point or between the airbag. There may also be more than two airbags, wherein at least one intermediate portion of the release element may be connected to the third airbag via a connection point. The minimum length of the release element should be adapted to the distance between the attachment points when the airbag is deployed, so as not to impede the deployment of the airbag. The maximum length of the release member should not be exceeded so that the desired tension can be applied to the release member.

According to a further advantageous embodiment, at least one airbag is folded such that the connection point connecting the release element to the respective airbag is arranged closer to the adhesive layer when the airbag is in the folded state than when the airbag is in the deployed state. Upon deployment of the respective airbag, an additional tensile force is thereby exerted on the release element substantially in its longitudinal direction, whereby the release element is tensioned. If the release element is connected to both airbags, both airbags can be folded accordingly.

In a further advantageous embodiment, the connection point connecting the release element to the airbag is arranged offset with respect to the fixing point or another connection point connecting the release element to another airbag in an offset direction with respect to a plane oriented transversely to the height direction of the intermediate space, the offset direction being oriented transversely to the direction of the distance of the plane between the airbag and the fixing point or between the airbags. In this way, by means of the release element, the adhesive layer can be detached or weakened in a plane arranged substantially parallel to the two components or in a plane arranged obliquely to this plane when the airbag is deployed.

In a further advantageous embodiment, the airbags are each connected to one of the components, wherein the connection point connecting the release element to the airbag is arranged on a portion of the airbag facing away from the component to which the airbag is connected. Thus, upon deployment of the airbag, both end portions of the release element are displaced in the direction in which the two airbag-connected components are not connected.

According to a further advantageous embodiment, the airbag is connected to one of the components and the other airbag is connected to the other of the components, wherein the connection point connecting the release element to the airbag is arranged on a portion of the airbag facing away from the one component, and wherein the connection point connecting the release element to the other airbag is arranged on a portion of the other airbag facing away from the other of the components. Thus, at the time of deployment of the airbag, the end of the release element connected to the airbag is displaced in the direction of the other of the components, while at the time of deployment of the other airbag, the end of the release element connected to the other airbag is displaced in the direction of the one component. In this way, the release element can cut through the adhesive layer in the height direction of the intermediate space or adhesive layer to weaken it.

Another advantageous embodiment provides that the release elements pass through the adhesive layer in a zigzag or circular pattern. In this way, the release element can produce a larger cut area in the adhesive layer upon deployment of the airbag, which is associated with a larger weakening of the adhesive layer. Thus, the force exerted by the airbag or airbags to separate the two components can be further reduced.

In another advantageous embodiment, a portion of the release element is cast into the adhesive layer. In this way, the part of the release element is integrated into the adhesive layer by form-fitting, thereby avoiding any deterioration of the adhesive layer as much as possible.

According to a further advantageous embodiment, the vehicle component is a front hood which absorbs energy. In a frontal collision of a pedestrian or a bystander with a vehicle, in particular of a motor vehicle, it may happen that the pedestrian (for example his head) hits the front hood or bonnet of the motor vehicle. The energy-absorbing front bonnet may be activated after the sensor detects a collision with a pedestrian, causing the one or more airbags to deploy such that, after the adhesive separation, an outer part of the front bonnet forming an outer skin of the bonnet is raised relative to an inner part of the front bonnet arranged inside the vehicle. In this way, the outer part is sprung up relative to the inner part by means of the airbag, so that the impact of a pedestrian on the front engine cover is reduced, reducing the risk of injury to the pedestrian.

Detailed Description

Fig. 1A shows a schematic side view of an exemplary embodiment of a vehicle component 1 according to the invention in a deactivated state, which vehicle component 1 may be configured as a front bonnet for absorbing energy.

The vehicle assembly 1 has two components 2 and 3, an intermediate space 4 between the components 2 and 3, an adhesive layer 5 arranged in the intermediate space 4, the two components 2 and 3 being joined together by means of the adhesive layer 5, and two airbags 6 and 7 arranged in the intermediate space 4, each airbag 6 and 7 being in a folded state. Both airbags 6 and 7 are connected to the component 3.

Furthermore, the vehicle component 1 has a thread-like release element 8, which is partially embedded or cast into the adhesive layer 5. The end of the release element 8 is connected to a part of the airbag 6 facing away from the component 3 by a connection point 9. The other end of the release element 8 is connected via a further connection point 10 to a part of the further airbag 7 which also faces away from the component 3. The adhesive layer 5 is disposed between the airbags 6 and 7. The release element 8 may extend through the adhesive layer 5 in a zigzag or circular manner.

In the deactivated state of the vehicle component 1, each airbag 6 or 7 is folded such that the connection point 9 or 10 connecting the release element 8 to the respective airbag 6 or 7 is arranged closer to the adhesive layer 5 than when the respective airbag 6 or 7 is in the deployed state, as is more evident when viewing fig. 1A and 1B together. In fig. 1A, the distance between the connection points 9 and 10 is a 1.

The connection point 9 connecting the release element 8 to the airbag 6 may be arranged offset in an offset direction with respect to a further connection point 10 connecting the release element 8 to a further airbag 7 with respect to a plane E oriented transversely to the height direction H of the intermediate space 4, the offset direction being oriented transversely to the direction of the distance a between the airbags 6 and 7 lying in the plane E and in a vertical state in the plane of the drawing.

Fig. 1B shows a schematic side view of the vehicle assembly 1 shown in fig. 1A in an activated state. From the deactivated state shown in fig. 1A, the activated state can be reached, because the airbags 6 and 7 have been deployed, whereby the connection points 9 and 10 have been moved away. This tensions and moves the release element 8, thereby cutting through the adhesive layer 5, thereby weakening the adhesive layer 5. When a release force is subsequently applied to the components 2 and 3 by the airbags 6 and 7, the adhesive layer 5 is broken so that the bonding of the components 2 and 3 by the adhesive layer 5 is eliminated. In fig. 1B, the connection points 9 and 10 are arranged spaced apart from each other by a distance a2, where a2 > a 1.

Fig. 2A shows a schematic side view of another exemplary embodiment of a vehicle component 11 in a deactivated state according to the present disclosure, the vehicle component 11 may be configured as a front bonnet for absorbing energy.

The vehicle component 11 differs from the exemplary embodiment shown in fig. 1A and 1B in that the airbag 6 is connected to the component 3 and the further airbag 7 is connected to the component 2, wherein the connection point 9, which connects the release element 8 to the airbag 6, is arranged on a part of the airbag 6 facing away from the component 3 and wherein the connection point 10, which connects the release element 8 to the further airbag 7, is arranged on a part of the further airbag 7 facing away from the component 2.

To avoid repetition, reference is additionally made to the above description with respect to fig. 1A.

Fig. 2B shows a schematic side view of the vehicle component 11 shown in fig. 2A in an activated state. From the deactivated state shown in fig. 2A, the activated state can be reached, because the airbags 6 and 7 have been deployed, whereby the connection points 9 and 10 have been moved away. This tensions and moves the release element 8, thereby cutting through the adhesive layer 5, thereby weakening the adhesive layer 5. When a releasing force is subsequently applied to the components 2 and 3 by the airbags 6 and 7, the adhesive layer 5 is broken so that the adhesion of the components 2 and 3 by the adhesive layer 5 is eliminated. In fig. 2B, the connection points 9 and 10 are arranged at a distance a2 from each other, wherein here again a2 > a 1.

Fig. 3A shows a schematic top view of a further exemplary embodiment of a vehicle component 12 according to the invention in a deactivated state, wherein parts of the vehicle component 12 delimiting the intermediate space 4 are omitted. The vehicle component 12 differs from the exemplary embodiment shown in fig. 1A and 1B or fig. 2A and 2B in that the release element 8 extends through the adhesive layer 5 in a zigzag shape.

Here, the connection point 9 connecting the release element 8 to the airbag 6 is arranged offset relative to the connection point 10 connecting the release element 8 to the further airbag 7 by a value a3 in an offset direction V, which lies in the plane of the drawing and is oriented transverse to the planar distance direction a between the airbags 6 and 7, relative to a plane lying in the plane of the drawing and oriented transverse to the height direction of the intermediate space 4 in the vertical state on the plane of the drawing.

To avoid repetition, reference is additionally made to the above description with respect to fig. 1A and 1B and 2A and 2B.

FIG. 3B illustrates a schematic side view of the vehicle component 12 shown in FIG. 3A in an activated state. From the deactivated state shown in fig. 3A, the activated state is reached, because the airbags 6 and 7 have been deployed, whereby the connection points 9 and 10 have been moved away. This tensions and moves the release element 8, thereby cutting through the adhesive layer 5, thereby weakening the adhesive layer 5. When a release force is subsequently applied to the components 2 and 3 by the airbags 6 and 7, the adhesive layer 5 is broken so that the bonding of the components 2 and 3 by the adhesive layer 5 is eliminated. In fig. 3B, the connection points 9 and 10 are arranged at a distance a2 from each other, wherein here again a2 > a 1. In fig. 3B, a cutting surface S is shown, which is created when cutting through the adhesive layer 5 by the release element 8.

Fig. 4 shows a schematic top view of an exemplary embodiment of the vehicle component 13 according to the invention in a deactivated state, wherein parts of the vehicle component 13 delimiting the intermediate space 4 are omitted. The vehicle component 13 differs from the exemplary embodiment shown in fig. 3A and 3B in that the release element 8 extends in a straight line through the adhesive layer 5.

To avoid repetition, reference is additionally made to the above description with respect to fig. 3A and 3B.

Fig. 5A shows a schematic side view of another exemplary embodiment of a vehicle component 14 in a deactivated state according to the present disclosure, the vehicle component 14 may be configured as a front hood to absorb energy.

The vehicle component 14 differs from the exemplary embodiment shown in fig. 1A and 1B in that, in the unexpanded state shown, each airbag 15 or 16 is not folded in a particular manner, and each airbag 15 or 16 is configured such that the geometry of the respective airbag 15 or 16 changes when the respective airbag 15 or 16 is expanded. In particular, the respective airbag 15 or 16 is configured such that its geometry changes from an uninflated state with a small height and with a large base area projected onto the respective component 2 or 3 to an inflated state with a higher height and with a smaller base area projected onto the respective component 2 or 3. In this way, as shown in fig. 5B, the distance L1 between the adhesive layer 5 and the corresponding airbag 15 or 16 is increased to L2. Thus, the distance between the connection points 9 and 10 of the release element 8 to the airbags 15 and 16 increases from a1 to a2, as is evident when viewing fig. 5A and 5B together. In this way, a tensioning force is exerted on the release element 8, which is accompanied by a desired weakening of the adhesive layer 5. The airbags 15 and 16 rest on the two parts 2 and 3 without interruption.

To avoid repetition, reference is additionally made to the above description with respect to fig. 1A.

Fig. 5B shows a schematic side view of the vehicle component 14 shown in fig. 5A in an activated state. From the deactivated state shown in fig. 5A, the activated state can be reached, because the airbags 15 and 16 have been deployed, whereby the connection points 9 and 10 have been moved away. This tensions and moves the release element 8, thereby cutting through the adhesive layer 5, thereby weakening the adhesive layer 5. When a release force is subsequently applied to the components 2 and 3 by the airbags 15 and 16, the adhesive layer 5 is broken so that the bonding of the components 2 and 3 by the adhesive layer 5 is eliminated. In fig. 5B, the connection points 9 and 10 are arranged at a distance a2 from each other, wherein here again a2 > a 1.

Fig. 6A shows a schematic top view of another exemplary embodiment of a vehicle component 17 according to the invention in a deactivated state, the vehicle component 17 being configurable as a front bonnet for absorbing energy.

The vehicle component 14 differs from the exemplary embodiment shown in fig. 5A and 5B in that there are a plurality of release elements 8 and 8a, each release element 8 and 8a being connected to one of the airbags 15 or 16 and being guided through the adhesive layer 5 in a loop-shaped manner, respectively. One release member 8a has a greater thickness than the other release member 8. In fig. 6A, the airbags 15 and 16 are arranged at a distance L1 from the adhesive layer 5. The release elements 8 and 8a may for example be connected to seams (not shown) of the airbags 15 and 16.

To avoid repetition, reference is additionally made to the above description with respect to fig. 5A.

Fig. 6B shows a schematic side view of the vehicle component 17 shown in fig. 6A in an activated state. The activated state is reached from the deactivated state shown in fig. 6A because the airbags 15 and 16 have been deployed, whereby the airbags 15 and 16 have been separated. This tensions and moves the release elements 8 and 8a, thereby cutting through the adhesive layer 5, weakening the adhesive layer 5. When a release force is subsequently applied to the components 2 and 3 by the airbags 15 and 16, the adhesive layer 5 is broken, so that the bonding of the components 2 and 3 by the adhesive layer 5 is eliminated. In fig. 6B, the airbags 15 and 16 are arranged at a distance L2 from the adhesive layer 5, where here again L2 > L1.
