Method of designing automotive seat assemblies for rear impact performance
A method for designing automobile seat assemblies in which a sled test is run on a prototype seat assembly in order to obtain the necessary data to model the seat assembly with simulation software. A basic model of the surface of the seat assembly is built utilizing simulation software and tests are run on various parameters to determine those that are most significant to the desired objective of the design process. Thereafter, the software is used to build a detailed model of the seat assembly and all its elements and the significant parameters are tested further to determine those that are again most significant to achieving the desired outcome. Once optimization ranges for those most significant parameters are chosen, the prototype seat assembly is modified accordingly. A final sled test is run on the modified prototype to verify the results and compare those results with the original sled test results.

Brace system and method for a vehicle at a loading dock
ActiveUS7841823B2Prevent downward movementRestricts downward movementSemiconductor/solid-state device manufacturingRefuse transferringSupporting systemEngineering
To help hold a (trailer) bed of a truck or trailer steady at a loading dock as the truck is being loaded or unloaded of its cargo, a yieldable vehicle brace exerts a substantial, but limited, reactive force upward against the trailer's rear impact guard to resist the trailer's downward movement. In some embodiments, the brace holds the trailer bed stationary up to a certain load limit and provides the trailer bed with a controlled or dampened descent when the load exceeds that limit. In some cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by one or more pressure relief valves, hydraulic fluid passing through a flow restriction, a brake, a spring, or various combination thereof. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard.

Motor vehicle capable of preventing malfunction and interrupting high-voltage system when accident occurs
ActiveUS20070152432A1Avoid failureDigital data processing detailsVehicular energy storageHigh pressureSide impact
An output of a semiconductor impact sensor contained in an air bag ECU is used to make determination in light of a criterion for interrupting a high-voltage power supply, which is different from a criterion for inflating an air bag so that the semiconductor impact sensor forms a redundant system along with a conventional safing sensor to prevent malfunction. Furthermore, an output of the semiconductor impact sensor contained in the air bag ECU is used to make determination for safing and output a safing signal thereby, so that a redundant system can be formed for a front impact sensor, a side impact sensor, and a rear impact sensor. Accordingly, malfunction can be prevented when tampering such as a strike with a hammer occurs.

Lever for ambidextrous magazine releases for firearms
A lever protects against inadvertent release of a magazine of a firearm if its ambidextrous release is hit by equipment when the firearm is carried. The lever is made from a projection, above the pivot point, having two opposing angles forward of the depression surface. The projection impacts the equipment before the depression surface is impacted (straight-on impact), which protects the assembly from inadvertent release of the magazine. An impact to the rear angle of the projection (a rear impact) increases the engagement of the lever with the magazine. An impact along the forward angle (from the front or straight-on) of the projection also serves to increase engagement of the lever with the magazine. The lever, with its projection having opposing angles, is specifically designed to protect the lever of an ambidextrous magazine catch from inadvertent release by impact / snag in the field.

Dynamic flip-up headrest
An active head restraint arrangement comprising a head restraint cushion, at least one head restraint post and head restraint post guide connecting said head restraint cushion to the interior of said passenger seats; and a flip-up assembly associated with said head restraint post beneath said head restraint cushion. Upon activation by rear impact, the flip-up assembly flips upward and forward to protect an occupant's head and neck from injury. Since this active head restraint arrangement utilizes a flip-up motion, the head restraint has a lower initial height that is dynamically increased upon activation. This feature allows the head restraint to be smaller allowing an occupant to have a better view around the head restraint.
