B-pillar trim strap for structural rigidity during CSA deployment
First Claim
1. A vehicle pillar garnish comprising:
- a first surface facing a vehicle interior;
a second surface opposite the first surface;
a top edge;
a pair of side edges extending up to the top edge;
at least one corner portion proximate the juncture of the top edge and at least one of the side edges; and
a rib extending outwardly from the second surface, the rib extending along the second surface at least partially between the side edges, the rib including at least one strap portion,wherein the rib is placed in tension and resists deformation of the at least one corner portion toward the vehicle interior when an inflation force is applied to the second surface adjacent the top edge and the rib is placed in compression and the at least one strap portion buckles when an impact force is applied to the first surface.

Abstract
Side pillar assemblies may include trim straps for structural rigidity during deployment of side airbag apparatuses. During deployment, the airbag can deploy from behind the roof head lining, above one or more pillar garnishes of the side pillar assembly and into the occupant compartment. A rib along the back surface of the pillar garnish may be placed in tension during a deployment event and inhibit fragmentation of the pillar garnish and limit movement of the pillar garnish into the occupant compartment. The rib may include one or more strap portions that may be placed in compression in the event of an impact on the interior facing portions of the pillar garnish. The strap portions may buckle under the compression force and provide a level of cushioning or energy dissipation due to the impact.

12. A vehicle pillar garnish comprising:
-
a first surface facing a vehicle interior; a second surface opposite the first surface; a top edge; a pair of side edges extending up to the top edge; at least one corner portion proximate the juncture of the top edge and at least one of the side edges; and a rib extending outwardly from the second surface, the rib extending along the second surface at least partially between the side edges, the rib including at least one void that defines at least one strap portion, the rib has a first width, and the at least one strap portion has a second width less than the first width, wherein the rib is placed in tension and resists deformation of the at least one corner portion toward the vehicle interior when an inflation force is applied to the second surface adjacent the top edge and the rib is placed in compression and the at least one strap portion buckles when an impact force is applied to the first surface. - View Dependent Claims (13, 14, 15, 16)

17. A vehicle assembly comprising:
-
an airbag apparatus including an inflatable airbag body, the airbag body being deployable adjacent a pillar of the vehicle; a pillar garnish operatively coupled to the vehicle pillar, the pillar garnish including; a first surface facing a vehicle interior; a second surface facing the vehicle pillar; a top edge; a pair of side edges extending up to the top edge; at least one corner portion proximate the juncture of the top edge and at least one of the side edges; and a rib extending outwardly from the second surface, the rib extending along the second surface at least partially between the side edges, the rib including at least one strap portion, wherein the rib is placed in tension and resists deformation of the at least one corner portion toward the vehicle interior when an inflation force is applied to the second surface adjacent the top edge by deployment of the airbag body, and the rib is placed in compression and the at least one strap portion buckles when an impact force is applied to the first surface. - View Dependent Claims (18, 19, 20)
