Specific embodiment
Fig. 1 show the vehicle 1 with trim panel 10 according to one embodiment of the invention.For example, shown trim panel 10 is Occupant side trim panel, is shown in Fig. 2.However, the trim panel 10 with air bag 52 (Fig. 4 C-4D) is also placed in appointing in 1 main cabin of vehicle What position.As shown in Figure 3A, trim panel 10 includes a rigid basement 14, is that whole trim panel 10 provides structural support.This is interior Plaque 10 also includes an outer layer or outer epidermal layer 18, and which has a visible first surface or referred to as outer surface 22, and One second surface contrary with the outer surface 22 or referred to as inner surface 26.The outer epidermal layer 18 by with the outer epidermal layer 18 in The supporting layer 30 that surface 26 is connected is strengthened.Additionally, froth bed 34 is formed between supporting layer 30 and rigid basement 14.
The outer epidermal layer 18 is made up of TPO (TPO) material, about 0.5 millimeter of its thickness.In some examples In, less than about 0.7 millimeter of the thickness of outer epidermal layer 18, between about 0.3 and about 0.7 millimeter.Therefore, outer layer in the trim panel 10 Trim panel (such as trim panel shown in Fig. 5 that the thickness of epidermis 18 is associated with passenger side air bag in being substantially less than prior art 110) outer epidermal layer thickness.That is, the thickness of outer epidermal layer 18 is sufficiently thin so that air bag 52 can launch and break through outer Layer epidermis 18 and need not outer epidermal layer 18 local manufacture or form any pre- atenuator region, indentation or otch (Fig. 3 A).Car Passenger in 1 can see that the outer surface 22 of outer epidermal layer 18, therefore, outer surface 22 can use different shape, pattern and matter Ground is meeting passenger's vision and aesthetic needs.
Outer epidermal layer 18 is thinning due to thickness, can be difficult to process when trim panel 10 is manufactured.But, in outer epidermal layer 18 Apply a supporting layer 30 on inner surface 26 and extra reinforcement is provided with outer layers epidermis 18 so as in the manufacture of trim panel 10 It is easily handled in journey.In the diagram embodiment of trim panel 10, supporting layer 30 is made up of polypropylene or polyethylene.Or, In addition, supporting layer 30 also can be made up of other different suitable materials or containing other different suitable materials.And, supporting layer 30 thickness is about at 1 millimeter to 4 millimeters.In the illustrated embodiment, about 1.5 millimeters of the thickness of supporting layer 30.Meanwhile, Foam in diagram embodiment for making supporting layer 30 has about 5 pounds per cubic feet of density.Trim panel 10 its In its embodiment, the density of supporting layer 30 can be in the range of 3 to 7 pounds per cubic feet, although the foam with different densities Or other materials can also be used.
Outer epidermal layer 18 forms a bilayer or Multi-layer structure member 50 with the supporting layer 30 below it, so in manufacture interior trim It is more easily handled during plate 10 and/or operates.Supporting layer 30 while extra booster action is provided to outer epidermal layer 18, not Air bag 52 is hindered to launch.And contribute to outer epidermal layer 18 during airbag deployment and tear.For example, due to supporting layer 30 with Outer epidermal layer 18 is integrated, and in airbag deployment, can prevent outer epidermal layer 18 from stretching or extending, so as to cause outer epidermal layer 18 Than trim panel of the prior art, (for example, in Fig. 5, trim panel outer epidermal layer 110) more promptly ruptures upon deployment.
As shown in Figure 3A, rigid basement 14 includes inwall 38, and the inwall 38 determines a perforate 42,52 (Fig. 4 C- of air bag 4D) can be opened by the perforate 42.Air bag guide housing 44 be placed in the perforate 42 and with rigid basement 14 at the inwall 38 phase Even.Air bag module 46 (including empty flat air bag 52) is coupled with air bag guide housing 44, is alignd with perforate 42.On air bag guide housing 44 Molding is formed with local thickness's weakened region (for example:Pre- atenuator region is 48) so that thus air bag 52 can be located smoothly to beat Open.When Fig. 4 A-4D show vehicle 1 and are clashed into, opening procedure of the air bag 52 through trim panel 10.When being clashed into, gas Launch in 52 slave module 46 of capsule, and start, in 10 times expansions of trim panel, to thrust air bag guide housing 44, make froth bed 34 and structural member 50 outwardly, as shown in Figure 4 B.As air bag 52 continues to expand, its break through froth bed 34 and structural member 50 (Fig. 4 C) until (Fig. 4 D) entirely pneumatic in main cabin.
Forming in the froth bed 34 between supporting layer 30 and rigid basement 14 is used for increasing pliability for trim panel 10.In figure In showing embodiment, the material of froth bed 34 is polyurethane material.Or, in addition, may also be employed other suitable foams and/or its Its material is manufacturing the layer 34.Meanwhile, in the illustrated embodiment, the foam density scope of froth bed 34 is manufactured at about 6 pounds to 12 Per cubic feet of pound, although the foam with different densities or other materials can also be used.Also, the thickness of froth bed 34 About 3 to 15 millimeters.In the diagram embodiment of trim panel 10, about 8 millimeters of the thickness of froth bed 34.
During manufacture trim panel 10, many of a reinforcement are initially formed by supporting layer 30 is applied on outer epidermal layer 18 Rotating fields part 50.For example, supporting layer 30 is applied on outer epidermal layer 18 using a kind of laminating technology.Then by Multi-layer structure member 50 move and position in a mold.As Multi-layer structure member 50 has supporting layer 30 to strengthen, therefore, in handling process, can be by The structural member 50 move to mould and without the need for considering braking or worrying in handling process, damaged thickness be thinner than it is of the prior art The outer epidermal layer 118 (Fig. 5) of trim panel 110.Additionally, during foam injection, as mentioned below, supporting layer 30 is prevented or is limited Make.In the method, supporting layer 30 can be as a kind of auxiliary manufacture hand The component that the allomeric function of section rather than a trim panel 10 completed to manufacture is made contributions.
Then, Multi-layer structure member 50 together with rigid basement 14 and air bag guide housing 44 it is fixed in a mold, and with it is rear About 8 millimeters of gap is left between the two.Then, a kind of fluid foam material is injected into this gap so as to after hardening or solidification Froth bed 34 is formed, so as to structural member 50 and rigid basement 14 and slideway 44 are connected together.Especially, in diagram trim panel In 10 embodiment, air bag guide housing 44 is fixed or is clipped between froth bed 34 and rigid basement 14.Then, the shape of froth bed 34 Air bag guide housing 44 and Multi-layer structure member 50 and substrate 14 are linked to be into an entirety effectively into step.After froth bed 34 solidifies, Trim panel 10 is removed from the molds.Then air bag module 46 is installed on guide housing 44, so as to complete the group of trim panel 10 Dress.Take additional process steps to form local thickness's weakened region, indentation or cut without the need for the inner surface 26 to outer epidermal layer 18 Mouthful, allow air bag 52 to break through it like a dream because outer epidermal layer 18 is sufficiently thin.
The different characteristic of the present invention is explained in the following claims.
