  • Patent number: 10825359
    Abstract: A method includes receiving data including 3-dimensional scans of a plurality of torsos, dividing each scan into a plurality of cross-sections, calculating an area for each cross-section, and calculating a torso volume based on the calculated areas. The method may include fitting a curve defined by parameters to each cross-section. The area for each cross-section may be an area enclosed by the curve. The method may include receiving a desired torso volume percentile, and determining values for the parameters of the curves corresponding to the desired percentile.

  • Patent number: 10741097
    Abstract: A jacket includes a ventral piece; left and right inferior dorsal pieces shaped to cover a left and a right inferior dorsal torso, respectively; and a posterior piece shaped to cover a posterior. The ventral piece includes a ventral portion shaped to cover a ventral torso, a superior dorsal portion connected to the ventral portion and shaped to cover a superior dorsal torso, and a detachably attachable seam splitting the superior dorsal portion. The inferior dorsal pieces are each attachable to the ventral portion and detachably attachable to each other. The posterior piece is detachably attachable to the inferior dorsal pieces.

  • Patent number: 10457241
    Abstract: An airbag assembly for a vehicle that includes a housing, an airbag supported by the housing, a deflector pivotally coupled to the housing, and a lock between the deflector and the housing. The lock is moveable relative to the deflector and the housing from an unlocked position disengaged with at least one of the deflector and the housing to a locked position engaged with both the deflector and the housing. The deflector may allow the airbag to deploy, without deflecting the airbag in response to one type of sensed impact, e.g., a full-width frontal impact, and may deflect the airbag in response to another type of sensed impact, e.g., oblique frontal impact.

  • Patent number: 8794399
    Abstract: A dynamic energy management restraint anchor device interfaces with a child seat in a vehicle, engaging common child seat attachment clip features. A device restraint anchor is operable to dynamically extract and permit distortion of load bearing deformable member(s) in order to manage the displacement of, and load transferred through, an anchor connected to a child seat. The device may be further operable to limit or prevent restraint anchor displacement and the distortion of said deformable member(s) under quasi-static load conditions in order to meet motor vehicle static load/displacement anchorage performance requirements applicable to certain anchors. Anchor retraction capability and various interlocking configurations for securing the position of an anchor, before or after having extracted, may be incorporated relative to the energy management device interfacing with both a vehicle and a child seat. An indicator may further be provided to identify the functional state of the restraint device.

  • Publication number: 20120209575
    Abstract: A method and system for assessing the accuracy and validity of a computer model constructed to simulate a multivariate complex dynamic system. The method and system exploit a probabilistic principal component analysis method along with Bayesian statistics, thereby taking into account the uncertainty and the multivariate correlation in multiple response quantities. It enables a system analyst to objectively quantify the confidence of computer models/simulations, thus providing rational, objective decision-making support for model assessment. The validation methodology has broad applications for models of any type of dynamic system. In a disclosed example, it is used in a vehicle safety application.
