The second wall 74 may be offset from the first wall 72. For example, the second wall 74 may be disposed proximate an outboard side of the side bolster assembly 10 and may be disposed forward of the first wall 72, or closer to the trim cover 30 than the first wall 72. In the embodiment shown in
The step wall 76 may extend between the first wall 72 and the second wall 74. For instance, the step wall 76 may extend from the first wall 72 to the second wall 74. The step wall 76 may face toward and may be disposed opposite the first cushion end surface 64. As such, the step wall 76 may help position the cushion 32 with respect to the carrier 36. In addition, the guide member 40 may be disposed between or may extend between the step wall 76 and the cushion 32. The step wall 76 may have a height from the first wall 72 to the second wall 74 that may be approximately the same as the thickness of the cushion 32 near the first cushion end surface 64. As such, the first cushion surface 60 may be generally aligned with the surface of the second wall 74 that supports the trim cover 30 to provide a desired appearance.
The lateral step wall 78 may extend between the first wall 72 and the rear seat 16. For example, a lateral step wall 78 may extend from the first wall 72 toward the rear seat 16 or vice versa. In addition, the lateral step wall 78 may be disposed proximate the second cushion end surface 66. As such, the lateral step wall 78 may help position the cushion 32 with respect to the carrier 36. The lateral step wall 78 may be disposed rearward of the step wall 76 or closer to the vehicle body 14 than the step wall 76 and one or more embodiments.
The airbag module 38 may be configured to deploy an airbag to help protect a seat occupant. The airbag module 38 may be received in the carrier 36. For example, the airbag module 38 may be disposed in the pocket between the first pocket wall 80 and the second pocket wall 82. In addition, the airbag module 38 may be supported by the carrier 36. For instance, the airbag module 38 may be mounted to a wall of the carrier 36 that at least partially defines the pocket 70, such as the third pocket wall 84. In at least one embodiment, the airbag module 38 may include a housing 100, an inflator 102, and an airbag 104.
The housing 100 may be configured to receive at least a portion of the airbag 104 when the airbag 104 is deflated or in a stored condition. The housing 100 may have a “soft” configuration or a “hard” configuration. In a soft configuration, the housing 100 may include a flexible cover, band, strap, or wrap that may extend around a deflated airbag 104 to hold or package the airbag 104 prior to deployment. In a hard configuration, the housing 100 may be a rigid container, such as a plastic or metal box, that may receive the deflated airbag 104. In either configuration, the housing 100 may open or separate in response to force exerted by the airbag 104 when the airbag 104 is inflated or deployed. In
The inflator 102 may provide an inflation gas to the airbag 104 to inflate the airbag 104 from a stored condition to an inflated condition. The inflator 102 may be fixedly positioned with respect to the carrier 36. For example, the inflator 102 may be mounted to the carrier 36 at or near the third pocket wall 84 so as to not interfere with or impede deployment of the airbag 104. The inflator 102 may be mounted in any suitable manner, such as with an inflator fastener 106 like a stud or bolt. The inflator 102 may be disposed in the pocket 70. Alternatively, the inflator 102 may be disposed outside the pocket 70 and may be fluidly connected to the airbag 104 via a tube.
The airbag 104 may be configured to deploy out of the side bolster assembly 10 when inflated. Moreover, the airbag 104 may be configured to cushion the head, thorax, and/or pelvis of the seat occupant when deployed. The airbag 104 may be configured to expand from a deflated or stored condition to an inflated or deployed condition when inflation gas is provided to the airbag 104. In the stored condition, which is shown in
The guide member 40 may be configured to help direct deployment of the airbag 104. For example, the guide member 40 may direct deployment of the airbag 104 from the pocket to the deployment seam 54. The guide member 40 may guide or direct deployment of the airbag 104 around the cushion 32 such that the airbag 104 does not deploy through the cushion 32 or through an opening in the cushion 32 upon inflation or when the airbag 104 is inflated. As such, the guide member 40 may route the airbag 104 around an end surface of the cushion 32, such as the first cushion end surface 64, before the airbag 104 reaches the deployment seam 54. For instance, the guide member 40 may extend between the cushion 32 and the first wall of the carrier 36 and then between the first cushion end surface 64 and the step wall of the carrier 36.
The guide member 40 may be fixedly coupled to a component of the side bolster assembly 10, such as the carrier 36 and/or the airbag module 38. In addition, the guide member 40 may include one or more panels. For example, the guide member 40 may include a first panel 110 and/or a second panel 112. The first panel 110 and the second panel 112 may be made of any suitable material or materials and may be a film, textile, sheet, or the like. The first panel 110 and the second panel 112 may or may not be separate pieces. For instance, the first panel 110 and the second panel 112 may be provided as a unitary component in which the first panel 110 and the second panel 112 may designate different portions of the guide member 40 that may be generally disposed on opposite sides of the airbag module 38. Alternatively, the first panel 110 and the second panel 112 may be separate components that may be directly fastened to each other, such as by stitching, or may not be directly fastened to each other. For instance, separate first and second panels 110, 112 may be attached to the inflator fastener 106, but may not be stitched to or fixed to each other in one or more embodiments. The first panel 110 and the second panel 112 may be disposed on opposite sides of the airbag module 38. As such, reference to the first panel 110 and the second panel 112 may be used to designate positioning relative to the airbag module 38.
The first panel 110 may be disposed on the outboard side of the airbag module 38 that may be disposed near the vehicle body 14 and opposite the rear seat 16. As such, the first panel 110 may be disposed between the airbag module 38 and the first pocket wall 80. The first panel 110 may extend around the cushion 32 and along the carrier 36. For example, the first panel 110 may extend along and may engage the first pocket wall 80, the first wall 72, the step wall 76, and optionally the interior surface 52 of the trim cover 30. As such, the first panel 110 may help guide deployment of the airbag 104 and may protect the airbag 104 or prevent the airbag 104 from engaging sharp edges of the carrier 36 during deployment. The first panel 110 may have a first end 120 that may be disposed proximate the deployment seam 54. In at least one embodiment, the first end 120 may be attached to the trim cover 30 proximate the deployment seam 54. It is also contemplated that the first end 120 may not be attached to the trim cover 30 in one or more embodiments.
The second panel 112 may be disposed on the inboard side of the airbag module 38 that may be disposed proximate the rear seat 16. As such, the second panel 112 may be disposed between the airbag module 38 and the second pocket wall 82. The second panel 112 may extend around the cushion 32 and primarily extend along the cushion 32. For example, the second panel 112 may extend along and may engage the second pocket wall 82, the cushion shield 34 (if provided), the first cushion end surface 64, and the first cushion surface 60. The second panel 112 may extend along the second cushion surface 62 when a cushion shield 34 is not provided. The second panel 112 may separate the first panel 110 and the cushion 32 such that the first panel 110 may engage the carrier 36 but may not engage the cushion 32. Likewise, the first panel 110 may separate the second panel 112 from the carrier 36 outside of the pocket 70 such that the second panel 112 may engage the cushion 32 but may not engage the first wall 72 or the step wall 76 of the carrier 36. The second panel 112 may have a second end 122 that may be disposed proximate the deployment seam 54. In at least one embodiment, the second end 122 may be attached to the trim cover 30 proximate the deployment seam 54. It is also contemplated that the second end 122 may not be attached to the trim cover 30 in one or more embodiments.

The insert panel 130 may be disposed between the trim cover 30 and the first wall 72 of the carrier 36′ such that the insert panel 130 may engage the interior surface 52 of the trim cover 30. In addition, the insert panel 130 may include a first insert panel end surface 132 and a second insert panel end surface 134. The first insert panel end surface 132 may be disposed proximate and may engage the guide member 40. The second insert panel end surface 134 may be disposed opposite the first insert panel end surface 132. The second insert panel end surface 134 may engage a lateral step wall 78. The insert panel 130 may be made of a different material than the cushion 32. For instance, the insert panel 130 may be made of a material that may be harder than the cushion 32, like expanded polypropylene foam.
The guide member 40 may extend between the cushion 32 and the insert panel 130. The first panel 110 of the guide member 40 may again be disposed on the outboard side of the airbag module 38 that may be disposed near the vehicle body 14 and opposite the rear seat 16. The second panel 112 of the guide member 40 may again be disposed on the inboard side of the airbag module 38 that may be disposed between the airbag module 38 and the rear seat 16.
The first panel 110 and the second panel 112 may extend around the cushion 32. For example, the first panel 110 may extend along and may engage the first pocket wall 80, the cushion shield 34 (if provided), the first cushion end surface 64, and the first cushion surface 60. The first panel may engage the second cushion surface 62 if the cushion shield 34 is not provided. The second panel 112 may extend along and may engage the second pocket wall 82, the first wall 72, the first insert panel end surface 132, and optionally the interior surface 52 of the trim cover 30. As such, the second panel 112 may help protect the airbag 104 from engaging sharp edges of the carrier 36 during deployment. The first and second ends 120, 122, of the first and second panels 110, 112, respectively, may be disposed proximate the deployment seam 54 as previously discussed.
