Description

The present invention relates to vehicle safety systems.

In particular, the invention relates to a method of manufacturing a security system, in particular for producing a security system comprising an airbag, or adapted to receive an airbag, or to be in front of an airbag. The invention also relates to a vehicle safety system comprising a body defining a body opening adapted to receive an airbag or to face an airbag.

Numerous documents describe such security systems and their manufacturing processes. Many solutions have been developed for manufacturing such secured systems to reduce the risk of injury to occupants of a vehicle.

document US2007 / 0052210 describes, for example, a safety arrangement and method for making such a safety arrangement with an airbag cover (or flap) implemented as a panel comprising a fluid-tight base and a bow, the arch being embedded in a foam which overlies a dashboard insert is injected to produce a dashboard. The sheet and fluid-tight base are fixed to the dashboard insert prior to the injection of foam through a mounted metal strip and mounting screws and / or an adhesive joint / joint. The assembled metal strip results in a significant increase in price and weight. In addition, the screw attachment involves an additional step during manufacture of the security system. Finally, the adhesive bond is difficult to implement. It is difficult to estimate the exact amount of adhesive to be applied, which can lead to licking of the foam during foam injection. In addition, the connection device must be cleaned regularly, resulting in regular shutdown operations of the manufacturing equipment to clean the connection device and then restart the connection device (in particular, due to the time to heat the adhesive).

Thus, the present invention aims to improve existing systems with the aim of reducing the risk of injury to vehicle occupants while preventing an increase in the weight and price of the assembly.

shows 8th a schematic cross-sectional view of the security system from 1 according to a fourth embodiment.

1 schematically illustrates the passenger compartment of a vehicle 1 which is equipped with a vehicle interior trim component, which is a safety system 10 according to the invention.

In this case, the interior trim component is a dashboard 12 , However, in alternative embodiments, the interior trim component of the vehicle could be a door panel, a roof interior trim, a seat or any other type of trim component with which the passenger compartment of a vehicle is equipped.

The security system, as in 2 . 3 . 4 . 5 . 6 and 8th shown includes a panel 14 and a body 16 which is a body opening 18 defined, which is adapted to an airbag 20 or an airbag module 20 take. The panel 14 may be embedded in foam or covered with foam to form a flap which is adapted to open in the event of a violent impact. In a known manner, the airbag deploys through an opening (especially the body opening) 18 ) in the passenger compartment when the airbag is inflated rapidly following an impact involving the vehicle.

The panel 14 has a fluid-tight base 22 on. The base 22 includes a cover portion 24 and a retention section 26 , The panel 14 , and in particular the cover section 24 which is the base 22 of the panel 14 covered, is set up to at least partially open the body 18 to cover. For example, the cover portion form 24 and the retention section 26 a continuous, substantially planar element. The retention section 26 can be arranged on a section. For example, the panel has a substantially rectangular shape with four edges and the retaining portion 26 may extend from one of the four edges. However, in alternative embodiments, the retention section may 26 extend from two or all of the four edges. The retention section 26 could also be arranged along the entire periphery of the cover, possibly continuously.

The retention section 26 the base 22 is in the body 16 embedded. In other words, the body becomes 16 produced by injection molding / injection molding and during injection molding is the retention section 26 the base 22 so oversprayed that the panel 14 with the body 16 connected is. The fact of embedding the retention section 26 in the body 16 (and more precisely in a part of the body 16 ) allows the panel 14 on the body 16 secure or the panel 14 on the body 16 withhold.

The base 22 is for example a thermoplastic material such as polypropylene or otherwise extruded polyamide 12 produced. The base 22 is, for example, a polypropylene fiber braid material. Typically, the thickness is the base 22 between 0.25 and 0.8 mm.

The body is made of thermoplastic material, for example.

The production of the security system 10 as described may be performed according to the following steps.

The first step is a step of providing the panel 14 which is the fluid-tight base 22 comprising a cover portion 24 and a retention section 26 having.

The second step is a step of providing a manufacturing mold used for injection molding of the body 16 is arranged, wherein the manufacturing mold comprises a cavity which is adapted to receive a material.

The third step is a step of positioning the base 22 of the panel 14 in the shape. The positioning of the panel 14 (comprising a base 22 ) in the form must be done accurately to eliminate any risk that the panel 14 relative to the body 16 which could, for example, lead to the creation of non-supported / supported portions of the instrument panel, which would create the possibility that, in the event of an impact and the opening of the flap, they would be quickly released into the passenger compartment of the vehicle.

The fourth step is a step of injecting a material, for example a thermoplastic material, into the mold so that the body 16 is formed, which the body opening 18 defined, which is adapted to the airbag 20 take. While injecting a material to the body 16 to generate, becomes the retention section 26 the base 22 embedded simultaneously to the panel 14 with the body 16 connect to. The positioning of the panel 14 in shape is the shape that after injection of the cover portion 24 of the panel 14 at least partially the body opening 18 covered. The panel 14 is made of a material which is resistant to the temperatures within the mold during injection.

In some embodiments or variants, which in particular in 2 . 3 . 4 and 6 The panel comprises 14 also a bow 28 , The arc 28 covered, for example, the cover section 24 the base 22 , The arc 28 can also do something or anything from the retention section 26 cover or he can not over the retention section 26 be arranged. The arc 28 For example, it includes a three-dimensional fabric material. A three-dimensional fabric material is a knitted and / or braided fabric in three dimensions, which for this reason has a certain thickness, which gives it some flexibility (significant: it deforms when pressed with a finger). The arc 28 can be made of polypropylene. The thickness of the bow 28 is between 3.5 and 5 mm. The panel 14 which is the fluid-tight base 22 and the bow 28 thus has some flexibility, but is fluid-tight.

It is intended that the body 16 of the security system 10 with a foam 30 is covered, in particular, to a dashboard 12 of a vehicle. During an injection of foam 30 on the body 16 of the security system (with which the panel 14 previously connected or on which the panel 14 previously fixed) becomes the panel 14 embedded in the foam. In particular, the bow 28 embedded in the foam. The fluid-tight base 22 prevents the foam 30 in it, in the body opening 18 enter.

In some embodiments, which in particular in 5 and 8th are shown, the panel comprises 14 only the base 22 without a bow and the base 22 is / is directly with the foam 30 covered.

The panel 14 which is in a foam 30 is embedded or with a foam 30 covered, forms a flap 32 which is set up to open in the event of a violent impact. A vulnerability line 34 limits the flap 32 , The vulnerability line 34 can be produced by a temperature-controlled / controlled hot-blade or a laser beam. In other embodiments, the vulnerability line may be 34 be formed directly when the body is formed. For example, the vulnerability line 34 by a non-continuous cutting of the panel 14 (trained from the base 22 and / or the bow 28 ) be generated. The vulnerability line 34 may also be referred to as a low resistance line.

As in 2 As shown, the body of the security system may be a firing channel 36 form in a first embodiment of the invention. The firing channel 36 limited a housing 38 which is adapted to the airbag 20 take. The firing channel 36 defines an opening for deployment of the airbag (the deployment opening and the body opening) 18 are united).

The body opening 18 corresponds to an opening in the housing 38 , In a known way, the airbag unfolds 20 through the body opening 18 in the passenger compartment when the airbag 20 quickly inflated following an impact on the vehicle. The firing channel 36 is through sidewalls 40 limited. The side walls 40 include, for example, mounting cavities or holes 42 for receiving hooks of an airbag module 20 to secure the module to the firing channel. The firing channel 36 further comprises a transverse wall 44 , The side walls 40 extend in a lateral direction X. The transverse wall 44 extends in a transverse direction Y. The transverse direction and the lateral direction may be substantially perpendicular to each other. The transverse wall 44 limits the body opening 18 ,

In this case, the shape of the panel 14 and more specifically, the shape of the cover portion 24 of the panel 14 essentially the same as that of the body opening 18 be. The panel may be of conventional size, which is substantially larger than the size of the body opening 18 is to complete it, as in 2 shown to cover. However, the panel could 14 have a smaller size than the deployment opening, so that it is only partially the body opening 18 covered.

The retention section 26 the base 22 of the panel 14 may extend from an edge of the cover portion, as mentioned above. For example, as in 2 illustrates the retention section 26 only from one side of the cover section 24 extend.

The panel 14 , and in particular the retention section 26 the base 22 of the panel 14 is in a section P _{t of} the transverse wall 44 of the firing channel 36 and in a portion P _{1 of} the sidewall 40 of the firing channel 36 embedded, like this in 2 can be seen. For example, the bow 28 of the panel 14 not in the firing channel 36 be embedded like this in 2 can be seen. More precisely, the bow extends 28 of the panel 14 from a shoulder of the firing channel 36 , Thus, only the basis 22 of the panel 14 partly in the firing channel 36 embedded. As in 2 can be seen is only the retention section 26 , which on only one side of the panel 14 is located in the firing channel 36 embedded.

It is intended that the firing channel 36 which with the panel 14 is provided on a dashboard insert 46 is fixed, for example by welding or gluing. The foam 30 will then over use 46 , the firing channel 36 and the panel 14 injected to form a covering layer over the entirety. The placement of the panel 14 , and more specifically the fluid-tight base 22 put the seal during an injection of the foam 30 ready. During an injection, the bow can 28 be embedded in the foam to the flap 32 train.

A reduction in thickness, either in the foam layer 30 or at the connection between the panel 14 and the body 16 , outside the area where the panel 14 in the body 16 embedded, the attenuation line can be 34 around the panel 14 define around. For example, the mitigation line is 34 U-shaped. The mitigation line 34 limits the flap 32 , The panel section 14 which is in the firing channel 36 is embedded, and therefore at the firing channel 36 is fixed, may remain integral with the firing channel in the event of an impact, so that the flap pivots substantially around this portion forming a hinge.

3 . 4 and 5 represent a second embodiment of the invention. The body 16 includes a transverse wall 48 which extends substantially in a transverse direction Y. recesses 50 which extend substantially in a lateral direction X are / are provided. The transverse direction and the lateral direction may be substantially perpendicular to each other. The transverse wall 48 limits the body opening 18 , The airbag module 20 can on the body 16 arranged / attached. The airbag module 20 can, for example, by means of a placement element 52 , such as a pin / stud, as in 3 . 4 or 5 which can be seen on the body 16 is fixed by overmolding, at the same time as the panel 14 be arranged / attached. The airbag module 20 could also be on the body 16 be arranged / attached by means of a screw connection. In such a case, there is a recess 50 the body is provided with a cavity for insertion of the locating element 52 and, for example, of the convent. During a training of the body 16 by injection molding, the retaining section 26 the base 22 of the panel 14 in the body 16 embedded. In such a case, the retention section is 26 the base 22 both in a section of the transverse wall 48 of the body as well as into a recess 50 embedded in a lateral direction X. During a training of the body by injection molding, the attenuation line 34 in the immediate vicinity of the edges of the panel 14 be generated simultaneously to the flap 32 define. It is intended the body 16 and the panel 14 which is attached to the body 16 is fixed to a dashboard insert 46 to fix. For example, the dashboard insert 46 be injected directly on the body to connect the body with the dashboard insert. However, in alternative embodiments, assembly / assembly may be provided by a reader or by gluing.

In the in 3 The example illustrated comprises the panel 14 a bow 28 which turns out to be a direct continuation of the transverse wall 48 of the body 16 and over the entire periphery of the body opening 18 which passes through the transverse wall 48 is limited.

In the in 4 example shown exists at the recess 50 in which the retention section 26 the base of the panel 14 is embedded between the arch 28 and the body 16 an offset (or an interruption). More precisely, the bow 28 at a non-zero distance from the body 16 arranged. This offset is placed only on the side of the panel embedded in the recess. In the other areas, the arch is essentially placed as a continuation of the body. In such a case, the bow covers 28 partially the cover section 24 of the panel 14 ,

In the in 5 The example illustrated comprises the panel 14 the fluid-tight base 22 and does not include a bow.

The arrangements made by the body 16 , the panel 14 and the dashboard insert 46 Be formed with a layer of a foam 30 and a skin 54 covered, which is the layer of a foam 30 covered.
