Abstract: Presented are devices for measuring dimensions of tear seams, methods for making/using such devices, and handheld clamp calipers for gauging material thicknesses of tear seams in passenger airbag breakaway panels. A handheld or automated measurement tool for determining seam dimensions includes first and second jaws operatively attached to a calibrated scale. The calibrated scale displays a measurement value fora dimension of a seam. The first jaw includes a first jaw tip projecting from a first jaw mandible. The second jaw includes a second jaw tip projecting from a second jaw mandible, which is movably attached with the first jaw mandible. Each of the jaw tips contacts a respective surface of the seam. An interior edge of the second jaw tip is disposed at an oblique angle of less than 90 degrees from an interior edge of the second jaw mandible.

Abstract: A method of manufacturing a workpiece includes heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven. A second fiber reinforced thermoplastic material is heated in an extruder. The second fiber reinforced thermoplastic material is extruded from the extruder, within the oven, to form an extrudate. The extrudate is positioned on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form a composite blank. The extrudate may be formed into a shape before being positioned onto the pre-formed blank, after being positioned onto the pre-formed blank. The composite blank may then be transferred to a final shaping station.

Abstract: An assembly for a vehicle includes a first member including a plurality of elastically deformable locating protrusions extending outward, and a second member defining a cavity extending inward and including a plurality of elastically deformable compression features disposed within the cavity. The locating protrusions of the first member are disposed within the cavity of the second member in press fit engagement with the compression features of the second member to secure the first member relative to the second member. The average of the elastic deformation between all of the locating protrusions of the first member and all of the compression features of the second member precisely aligns the first member relative to the second member. The assembly may include but is not limited to a multiple unit battery pack, a multiple unit fuel cell pack, a dashboard assembly or adjoining body panels.

Abstract translation: 一种用于车辆的组件包括：第一构件，包括向外延伸的多个可弹性变形的定位突起;以及第二构件，其限定向内延伸的空腔，并且包括设置在空腔内的多个可弹性变形的压缩特征。 第一构件的定位突起设置在第二构件的空腔内，与第二构件的压缩特征压配合，以相对于第二构件固定第一构件。 第一构件的所有定位突起和第二构件的所有压缩特征之间的弹性变形的平均值使第一构件相对于第二构件精确对准。 组件可以包括但不限于多单元电池组，多单元燃料电池组，仪表板组件或相邻的主体面板。
