Bolster deployment pattern
US 7992895 B2
16. The bolster of claim 15 wherein said first expandable area includes at least one first pleat and said flow path extends along said pleat.
As used in this description and claims, the term “lateral” is used to describe the transverse width of the bolster. If the bolster were mounted against an instrument panel, the lateral extent of the direction would be transverse of the vehicle. If the bolster were mounted to a door frame, the lateral extent of the bolster would extend longitudinally of the vehicle. If the bolster were mounted on an angular support pillar such as an A pillar, the lateral length of the bolster would extend longitudinally and angularly of the vehicle. In short, the term “lateral” is intended to encompass any mounting location of the bolster with regard to the vehicle.
Preferably, the bolster 10 is made in a blow molding operation. In blow molding, a parison is extruded, the parison is enclosed in a blow mold structure, and a blowing gas is injected into the interior of the parison. Upon expansion of the parison, the parison then expands so as to obtain the shape of the mold cavity. Generally speaking, the wall thickness of the parison is relatively uniform throughout the expanded parison subject to the necessity of plastic flow to obtain the shape as defined by the mold. In the blow molding process, slides can be established in the mold. The term “slide” is used to describe a structure that is used to move from a withdrawn position (usually not in the mold cavity) to an extended position, before the parison has cooled. By extending the slide, which effectively moves the slide against the wall of the parison, the wall of the parison is stretched to move inwardly of the mold surface. Thus, use of a slide may be used to create the at least one pleat 72 in connection with the extension structure 18 and to locate that structure so that it extends internally of the housing 20. The use of the slide does not, however, rupture the wall of the parison. Thus the finished product can still remain as a housing defining a substantially closed volume. Use of the slide, will create a diminution of the thickness of the wall of the parison, this helps to create a relatively thinner wall, which is then capable of undergoing the movement between the un-deployed and deployed configurations illustrated in FIGS. 7 and 8 without rupture of the wall of the housing. To facilitate movement of this type, the plastic used for the parison may be selected from the group of suitable materials including by way of example thermoplastic olefins or a plastic available from Salflex Polymers under the trade mark SALFLEX 245™.
