  • Patent number: 11654986
    Abstract: A compound dowel for positioning a first component defining a first aperture relative to a second component defining a second aperture in a motor vehicle body structure in response to a determined misalignment between the first and second components includes a compensation pin. The compensation pin is selected in response to the determined misalignment and configured to be inserted into the second aperture. The compensation pin has a center axis and an indexing feature configured to orient and fix the compensation pin to the first component. The compound dowel also includes a nominal pin arranged parallel to the center axis and offset therefrom by a distance. The nominal pin is configured to be inserted through the first aperture, such that position of the first component is set relative to the second component. A method of positioning components in a vehicle body structure using a compound dowel is also considered.

    Abstract: A method of positioning components in a body structure of a motor vehicle includes determining a misalignment between a first aperture defined by a first component and a second aperture defined by a second component. The method also includes selecting, in response to the determined misalignment, a compensation pin having a center axis and an indexing feature. The method additionally includes inserting a nominal pin through the first aperture, wherein the nominal pin is parallel to the center axis and shifted therefrom by an offset distance. The method also includes orienting and fixing the compensation pin to the first component via the indexing feature. The method further includes inserting the compensation pin into the second aperture, thereby setting position of the first component relative to the second component. A vehicle body structure using such a component positioning method and a compound dowel having the compensation pin are also considered.

  • Patent number: 10864872
    Abstract: An occupant airbag system for use in a vehicle with a retractable steering wheel includes a first airbag assembly located in the retractable steering wheel. The first airbag assembly is configured to deploy a first airbag cushion between an occupant and a rigid structure of the vehicle. The occupant airbag system also includes a second airbag assembly configured to deploy a second airbag cushion between the occupant and the rigid structure of the vehicle. The occupant airbag system also includes an airbag control module configured to suppress deployment of the first airbag cushion and to enable deployment of the second airbag cushion when the retractable steering wheel is in a retracted position.
