In some aspects, the techniques described herein relate to a method, wherein the bolster includes an array of inboard pockets on an inboard side of the bolster and an outboard array of pockets on an outboard side of the bolster.
In some aspects, the techniques described herein relate to a method, further including snap-fitting the bolster to at least one of the first beam or the second beam.
In some aspects, the techniques described herein relate to a method, wherein the bolster has an inboard side having an grid of inboard ribs and an outboard side having an grid of outboard ribs.
The embodiments, examples and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
The various features and advantages of the disclosed examples will become apparent to those skilled in the art from the detailed description. The figures that accompany the detailed description can be briefly described as follows:
This disclosure details a bolster for use in a side door of a vehicle. The bolster can, among other things, help to manage loads applied to the vehicle, particularly a load applied to a side of the vehicle.
With reference to
In this example, the side door 10 includes a first beam 20 and a second beam 22, and a bolster 26. The first beam 20, the second beam 22, and the bolster 26 are held within the interior area 16 of the side door 10 and are disposed between the inner panel 12 and the outer panel 14. The first beam 20 is a vertically upper beam. The second beam 22 is a vertically lower beam. Vertical, for purposes of this disclosure, is with reference to ground in a general orientation of the side door 10 when installed within a vehicle.
The first beam 20 and the second beam 22 are reinforcement beams in this example. The first beam 20 and the second beam 22 are a metal or metal alloy material. The first beam 20 and the second beam 22 can be considered body in white (BIW) beams.
The first beam 20 and the second beam 22 can help to reinforce the side door 10. The first beam 20 and the second beam 22 can help to manage loads applied to the side door 10. In this example, the bolster 26 is incorporated into the side door 10 to help manage loads applied to the side door 10 and the vehicle to which the side door 10 is attached.
With reference now to
The bolster 26 incorporates a snap-fit feature 32, which can snap-fit the bolster 26 to, in this example, the first beam 20. The snap-fitting of the snap-fit feature 32 to the first beam 20 can hold a position of the bolster 26 while securing the mechanical fasteners 30. The snap-fit feature 32 thus provides an assembly aid.
The bolster 26 can be a polymer-based resin component. In this particular example, the bolster 26 is nylon.
The bolster 26 has an inboard side 40 and an opposite outboard side 42. The inboard side 40 has a grid 44 of inboard ribs 46. The grid 44 of inboard ribs 46 establishes an array of inboard pockets 48 within the inboard side 40 of the bolster 26. The outboard side 42 of the bolster 26 includes a grid 50 of outboard ribs 52. The grid 50 of outboard ribs 52 establishes an array of outboard pockets 54 within the bolster 26.
The inboard pockets 48 and the outboard pockets 54 have rectangular profiles in this example. In other examples, the inboard pockets 48 and the outboard pockets 54 could have other profiles, such as a hexagonal profile. A width of the inboard pockets 48 and the outboard pockets 54 is about 23 to 25 millimeters in this example. The inboard ribs 46 and the outboard ribs 52 are about 3 millimeters thick.
The grid 44 of inboard ribs 46 and the grid 50 of outboard ribs 52 reinforce areas of the bolster 26 to facilitate managing of loads applied to the side door 10. The bolster 26 is reinforced without requiring significant additional material. As a load is applied to, for example, the outer panel 14, the side door 10 receives the load. At least some of the load is distributed through the bolster 26.
The example bolster 26 includes a single array of the inboard pockets 48 and a single array of the outboard pockets 54. With reference to
In the example bolster 60, the first bolster section 62 includes a first array of inboard pockets 70A and the second bolster section 64 includes a second array of inboard pockets 70B. Further, the first bolster section 62 includes a first array of outboard pockets 72A, and the second bolster section 64 includes a second array of outboard pockets 72B. The first bolster section 62 is spaced a distance from the second bolster section 64, and connected by the connecting arm 66. Thus, the bolster 60 includes separate and distinct arrays of pockets on the inboard side and separate and distinct arrays of pockets on the outboard side.
Referring again to
The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. Thus, the scope of protection given to this disclosure can only be determined by studying the following claims.
