In an illustrated embodiment, stabilized zone 370 includes the carrying material of single any suitable species. Such as, in many embodiment, described carrying material can include any suitable fabric, such as nylon Sideband.Penetrate portion 374 to be formed by single belt material, otherwise, maintaining part 375 is by sandwich tape material Formed.Specifically, can be by single belt material winds or is folded back into himself twice and general's seam At conjunction, 376 are secured across the carrying material of three layers of formation and form maintaining part 375.In shown enforcement In example, suture 376 is formed at the position in the middle of three layer segment approximations of the carrying material of folding.Cause This, when maintaining part 375 be oriented relative to penetrate portion 374 laterally extend time, such as Figure 21 and Shown in Figure 24, described maintaining part 375 includes the carrying material of the two superimposed on suture 376 side Carrying material with three plies on described suture 376 opposite side.When maintaining part 375 relative to Penetrating portion 374 when being at first laterally oriented, stabilized zone 370 generally defines T-shape.Shown In embodiment, maintaining part 375 starts penetrating both sides, portion 374 towards lateral from penetrating portion 374 Extend identical distance.

As shown in figure 24, in an illustrated embodiment, the end of carrying material is sandwiched in two webs material Between and be placed in the inside of maintaining part 375.Additionally, maintaining part 375 can be located at stabilized zone 370 End.In other embodiments, the maintaining part 375 in stabilized zone 370 can be located at stabilized zone 370 (such as penetrating portion 374 can be relative to maintaining part 375 farther side ground or closer to side in middle position Ground extends).But, in an illustrated embodiment, T-shaped stabilized zone 370 and device 300 The T-shaped slit of housing 390 is complementary, and in described stabilized zone 370, maintaining part 375 is positioned at the portion of penetrating The end of 374.The manufacture of device 300 is easy to or is contributed in this installation, this will hereinafter do into One step discussion.

With reference to Figure 22, housing 390 defines that installing component 391, described installing component 391 are joined It is set to described stabilized zone 370 that interact to will at least during the expansion of air bag back cushion 310 Housing 390 is fixed in a part of stabilized zone 370.In an illustrated embodiment, installing component 391 Including stablizing with holes 392.Figure 22 shows air bag back cushion 310 and the housing being in pre-mounted state 390.To describe stabilized zone 370 via stablizing with holes 392 even in conjunction with Figure 23 A to Figure 23 D subsequently The method receiving housing 390.Figure 23 D (i.e. SW will be described under discussion₁And SW₃) and Figure 24 (i.e. ST₁、ST₂And SW₂The stabilized zone 370 identified in) and multiple sizes of opening 392.

Figure 23 A depicts the inner surface of housing 390.As indicated, stablize with holes 392 to include two Section 392a of wire roughly, 392b, the most generallyperpendicular extension of said two linear parts. In other words, stablize with holes 392 and define the T-shape substantially complementary with T-shaped stabilized zone 370. In certain embodiments, as discussed further below, T-shaped stablize with holes 392 at least some of T-shaped slit slightly larger than stabilized zone 370.In an illustrated embodiment, width S W of section 392a₁ (Figure 23 D) is more than width S W of section 392b₂(Figure 24).Therefore, section 392a is referred to here as Wide section 392a or wider section of 392a, otherwise, section 392b is referred to as narrow section of 392b or narrow section 392b. Additionally, section 392a may be additionally referred to as inserting paragraph 392a, section 392b is referred to as remaining section 392b, former Because finding out from discussion below.

With reference to Figure 23 A and Figure 26, in an illustrated embodiment, inserting paragraph 392a generally with longitudinal direction Direction extends crosscuttingly, and towards the expansion direction with at least starting stage of air bag back cushion 310 The most corresponding direction and be elongated, this is marked by arrow label " DEPLOY " in fig. 26 Know.Residue section 392b extends in longitudinal direction, and therefore it is generally relative to the common exhibition of air bag Evolution extends to crosscutting.Although described air bag back cushion is typically to launch forward relative to housing 390 , it should be noted that air bag back cushion 310 not launches along single direction.Such as, In certain embodiments, advance downwardly to open outside housing 390 when air bag back cushion 310 starts Open the lid (not shown) bottom housing 390, then push ahead in generally horizontal direction, with And the bottom up of this tailing edge instrument face plate and extending forward, this is expectation for knee air bag Track.Therefore, the expansion direction in Figure 26 " DEPLOY " generally illustrates air bag back cushion 310 Described air bag back cushion advances when housing 390 launches general direction or final direction.

Refer again to Figure 23 A, be connected to the starting stage of housing 390, stabilized zone in stabilized zone 370 370 align with stabilized zone opening 392, in order to make maintaining part 375 and the opening in stabilized zone 370 The central axis of inserting paragraph 392a of 392 is consistent (the most coplanar), and to make stabilized zone 370 Thin section be consistent (the most coplanar) with the central axis of residue section 392b of opening 392.Such as Figure 23 A In black arrow shown in, stabilized zone 370 advances towards stabilized zone opening 392 in the direction of the arrow.

As Figure 23 B paints, the end section in stabilized zone 370 advances through stabilized zone opening 392.? Advancement stage, the longitudinal axis in stabilized zone 370 becomes with the wall of the housing 390 defining opening 392 One angle.This angle is affected by the length of residue section 392b.The length of residue section 392b The longest, the angle between stabilized zone 370 and housing wall is the least.In certain embodiments, due to This angular relationship between stabilized zone 370 and housing wall, and due to the thickness of housing wall, reason Situation about thinking is the width guarantor slightly larger than stabilized zone 370 of inserting paragraph 392a of stabilized zone opening 390 Hold the thickness in portion 375, in order to ensure that portion 375 can easily pass through inserting paragraph 392a.

As Figure 23 C paints, the maintaining part 375 in stabilized zone 370 has already passed through inserting of opening 390 After the section of entering 392a, stabilized zone 370 is rotatable.Therefore maintaining part 375 is in housing 390 Outside, penetrate at least some of of portion 374 simultaneously and remained in the inside of housing 390.

As Figure 23 D paints, stabilized zone 370 may pass through residue section 392b of opening 392 and arrives described The end relative with inserting paragraph 392a of opening 392.In many embodiment, residue section 392b Thickness SW₂It is approximately equal to or greater than the thickness ST in the portion that penetrates 374 in stabilized zone 370₂, in order to favourable This shifted laterally in stabilized zone 370.In other embodiments, the width of section 392b is remained SW₂Can be slightly less than the thickness ST in the portion of penetrating 374 on the contrary₂, in order to allow this of stabilized zone 370 Shifted laterally, but also this shifted laterally can be produced frictional resistance.In any instance, residue Width S W of section 392b₂(Figure 24) maximum of the maintaining part 375 in stabilized zone 370 it is desirably less than Thickness ST₁, this can stop maintaining part 375 to pass the residue section of opening 392 from the outside of housing 390 392b and be pulled into the inside of housing 390.Additionally, width S W in stabilized zone 370₃(Figure 23 D) It is desirably larger than width S W of inserting paragraph 392a of opening 390₁(Figure 23 D), so in stabilized zone In the case of 370 will be pulled back to inserting paragraph 392a, it is possible to stop maintaining part 375 by from housing 390 Outside be pulled into the inside of housing 390 through inserting paragraph 392a of opening 392.

With reference to Figure 24, in other embodiments, the maintaining part 375 in stabilized zone 370 is maximum thick Degree ST₁It is smaller than width S W of residue section 392b of opening 392₁.In such instances, define A part for the housing 390 of residue section 392b remains to stop maintaining part 375 to be pulled into housing 390, This is because along with walking or drive slowly in the case of under tension in stabilized zone 370, outside from suture 376 A part for the maintaining part 375 extended will bind together, and this can form a thickness more than surplus Width S W of remaining section 392b₂The carrying material of bulk.
