A vehicle seat restraint system includes a control system and a second-row restraint system. The control system receives a first-row seat value and a second-row seat value from seat sensors. The control system generates relative position data for a first-row seat and a second-row seat based upon the first-row seat value and the second-row seat value. The control system selects a load limiter setting value using a multidimensional load limiter model based upon body impact values as a function of load limiter setting values and the relative position data, a selected load limiter setting value outside a value avoidance zone for the body impact values. The second-row restraint system is configured by the control system with the selected load limiter setting value. The control system may also determine an occupant weight value and select the load limiter setting value using the occupant weight value.

Load limiter configuration using multidimensional model

A method includes: determining first and second row seat values using seat sensors; generating relative position data for the seats using the values; selecting a load limiter setting value using the relative position data and a multidimensional load limiter model including at least i) body impact values as a function of at least load limiter setting values and as a function of relative position values, and ii) restraint interaction values as a function of at least the load limiter setting values and as a function of the relative position values, the load limiter setting value selected so that the load limiter setting value is outside a first value avoidance zone defined for the body impact values, and outside a second value avoidance zone for the restraint interaction values; and configuring a second row restraint system in the vehicle with the selected load limiter setting value.

A method includes: determining a design for a longitudinal piece of a particular length, wherein first and second ends of the longitudinal piece have dissimilar shapes; extruding a piece that is at least twice the particular length, wherein a profile throughout the extruded piece has the first end shape; hydroforming the extruded piece to generate an expanded portion between ends of the extruded piece, wherein the ends retain essentially the first end shape; and cutting through the expanded portion to obtain a piece wherein one end has the first end shape and another end has the second end shape.

Extrusion piece with dissimilar ends

A system for decoupling a HV source from an electric vehicle's electrical system is provided that includes (i) at least one electrical contactor, where the HV source is electrically connected to the vehicle's electrical system when the electrical contactor is in a closed state and not electrically connected to the vehicle's electrical system when the electrical contactor is in an open state; (ii) a supplemental restraint system (SRS) that monitors collision data from a plurality of impact sensors and outputs an activation signal in response to monitored collision data; and (iii) a pyrotechnic switch, where the pyrotechnic switch has a pre-activated first state that provides a conductive path that allows the HV source to be electrically connected to the vehicle's electrical system and an activated second state that severs the conductive path and prevents the HV source from being electrically connected to the vehicle's electrical system.
