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.
