The same readiness indicator required by S of FMVSS No. may be used to meet the requirement. A list of the elements of the system being monitored. FMVSS requires component-level tests to be conducted on ejection mitigation countermeasures (e.g., rollover-activated side curtain. In , the U.S. legislation adopted – with the Federal Motor Vehicle Safety Standard (FMVSS) – a new safety rule, which aims at reducing the risk to be.

These comments will aid the Agency in setting research priorities as well as inform its subsequent actions to lay a path for innovative vehicle designs and technologies that feature ADSs.

We believe that, by requiring that ESC systems be installed on the rest of truck tractors and large buses, fmvas final rule will prevent 40 to 56 percent of untripped rollover crashes and 14 percent of loss-of-control crashes. Inthe U.

With the seat in any non-forward facing orientation, the seat back set at an inclination position closest to the manufacturer’s design seat back cmvss, and all other seat adjustments at any possible position of adjustmentdetermine the location of a vertical transverse vehicle plane located ffmvss the portion of the seat rearmost in the vehicle, at the distance specified in 5.

The original comment period closed September 21, In addition, to the extent warranted under the National Traffic and Vmvss Vehicle Safety Act, establishing advanced glazing standards for the side and rear portals of the subject buses would fulfill a statutory provision of the Motorcoach Enhanced Safety Act of incorporated and passed as part of the Moving Ahead for Progress in the 21st Century Act.

You should submit your comments to ensure that Docket Management receives them not later than July 20, Full compliance is required on September 1, The ejection impactor consists of an ejection headform attached to a shaft. Summary This NPRM proposes to upgrade the Rmvss motor vehicle safety standards that address rear underride protection in crashes into trailers and semitrailers.

Federal Motor Vehicle Safety Standard 226

Petitions for reconsideration of this final rule must be received not later than February 1, The glazing is pre-broken, fully retracted or removed prior to the impact test S5. Thompson has not identified a safety need to justify making changes he requested, 2266 Mr.

The resulting value must not exceed 0. Summary This document grants the petition for rulemaking submitted by the Truck Safety Coalition, the Center for Auto Safety, Advocates for Highway and Auto Safety, and Road Safe America on February 19,to establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles. Side daylight opening means, other than a door openingthe locus of all points where a horizontal lineperpendicular to the vehicle vertical longitudinal plane, is tangent to the periphery of the opening.

For the tests specific requirements on the duration of the inflation of the airbag are introduced, since the impact of the impactor takes place up to 6 seconds after the ignition of the airbag. Written comments must be received on or before March 20, in order to be considered timely. The potential effectiveness of such a tool to successfully aid an occupant’s safe exit from an immersed vehicle is also not known.

The indicator shall monitor its own readiness and must be clearly visible from the driver ‘s designated seating position. The static deflection measurement is made with the ejection impactor extended mm outboard of the theoretical point of impact with the countermeasure and attached to the ejection propulsion mechanismincluding vmvss support frame and anchors.

The effective date of this final rule is September 26, Determine the location of an offset-line within the side daylight opening by projecting each point of the side daylight opening laterally onto a vehicle vertical longitudinal plane.

The agency requests comments on fkvss alternative strategy and other potential enhancements to the current fmvsss block test procedure. If more than one position exists that is closest to the geometric center of the side daylight openingselect the lowest.

The force is applied once in each of the following headform axes: Ejection propulsion mechanism means a device that is a component of the ejection mitigation test device consisting of a mechanism fmbss of propelling the ejection impactor and constraining it to move along its axis or shaft.

Locate the geometric center f,vss the side daylight openingestablished in S5. Summary This document responds to a petition for reconsideration of the agency’s November final rule making amendments to the procedures for determining which areas of a vehicle are designated seating positions and the procedure for determining the number of seating positions.

This standard establishes requirements for ejection mitigation systems to reduce the likelihood of complete and partial ejections of vehicle occupants through side windows during rollovers or side impact events.

A main focus of his work as team leader in vehicle safety development is on the analysis and implementation of new test methods and requirements, such as FMVSS Hofferberth on April 1, By continuing to use our website without changing the settings, you are agreed to our use of cookies.

The location of the most outboard surface of the headform establishes the zero displacement plane for this target location. Toyota and the Auto Alliance Alliance.

If after performing the procedure in this section, the remaining targets exceed the number of targets determined with the original orientation of the targetthe reoriented targets represent the final target locations for the side daylight opening. Zero displacement plane means, a vertical plane parallel to the vehicle longitudinal centerline and tangent to the most outboard surface of the ejection headform when the headform is aligned with an impact target location and just touching the inside surface of a window covering the side daylight opening.

Repeat the measurement in three more orientations with the ejection impactor and any associated bearings and bearing housing rotated 90, and degrees about the headform y axis. If this distance is greater than or equal to mm, place a target such that its center bisects a line connecting the centers of the remaining targets.

Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a net benefit to safety. The data available to the agency shows there is a great deal of uncertainty surrounding the actual number of occupants that may have died due solely to drowning while trapped in an immersed vehicle. The proposed FMVSS would also require each vehicle, as manufactured and sold, to have its device set to a speed not greater than a specified speed and to be equipped with means of reading the vehicle’s current speed setting and the two previous speed settings including the time and date the settings were changed through its On-Board Diagnostic connection.

When the last row seat adjacent to the opening, in the case of a vehicle with fewer than 3 rows, or the 3rd row seat adjacent to the opening, in the case of a vehicle with 3 or more rows, is not fixed in the forward facing direction, the offset line may extend farther rearward than specified in S5.

Ejection Mitigation FMVSS 226: Requirements – Testing – Development Strategies

Restoration of the side marker requirements will have no negative impact on safety or function and will allow motor vehicle manufacturers to avoid unnecessary modifications to fvmss side marker lamps with no added safety or functional benefit. Fmmvss ANPRM requests comment on NHTSA’s estimated cost fmvsd benefits of requirements for underride guards on single unit trucks, and for retroreflective material on the rear and sides of the vehicles to improve the conspicuity of the vehicles to other motorists.

The effective date of the final rule published on December 14, 81 FRis delayed until September 5, After a careful technical review of the petition and the issues raised by the petitioner, the agency has decided to grant the petition because there is sufficient evidence to indicate that a larger lane width is needed for testing of long wheelbase truck tractors.

Petitions for reconsideration of this final rule must be received not later than January 30,
