FMVSS 226 PDF

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.

The original comment period closed September 21, Public comments are welcome at this meeting, but fmvsz should be oral, and any supporting presentations or materials should be submitted to the docket for consideration. 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.

In the absence of a requirement fmmvss each vehicle have a glass breaking tool, nothing prevents vehicle manufacturers from providing a tool or other means to allow vehicle evacuation during immersion. The comment period for the request for comment published January 18,at 83 FRis extended. Based on the petition, available information, and the agency’s analysis in progress, NHTSA has decided that the Petitioners’ request related to rear impact guards merits further consideration.

Divide the side daylight opening into four quadrants by passing a vertical line and a horizontal linein a vehicle vertical longitudinal plane, through the geometric center of the side daylight opening.

Ejection mitigation test device specifications. The focus of this notification is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment. After consideration of the petitions and all supporting information, NHTSA has decided to grant the petitions for four of the discrete changes, deny one, and request comment in a separate document for the sixth proposed fmvs.

The agency agrees that the change was inadvertent and is issuing this final rule to correct this mistake. Vehicles that are not subject to the phase-in may be certified as meeting the requirements specified in this standard. Both of those applications address intersection crashes, which are among the most deadly crashes that U.

The glazing is pre-broken, fully retracted or removed prior to the impact test S5. 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. This standard applies to passenger cars, and to multipurpose passenger vehiclestrucks and buses with a gross vehicle weight rating of 4, kg or less, except walk-in vans, modified roof vehicles and convertibles.

Check-in through security will begin at 9 a. The focus of this notice is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, fmvsz, motorcycles, and motor vehicle equipment.

For vehicles that have an ejection mitigation countermeasure that fmbss in the event of a rollover, the vehicle manufacturer must make available to the agency, upon request, the following information: We believe that, by requiring that ESC systems be installed on the rest of truck tractors and large buses, this final rule will prevent 40 to 56 percent of untripped rollover crashes and 14 percent of loss-of-control crashes. Thompson has not identified a fnvss need to justify making changes he requested, and Mr.

Locate the geometric center of the side daylight openingestablished in S5. Using the ejection propulsion mechanismpropel the ejection impactor such that it first strikes the countermeasure, while aligned with any target location specified in S5.

Ejection Mitigation FMVSS 226: Requirements – Testing – Development Strategies

The location of the most outboard surface of the headform establishes the zero displacement plane for this target location. It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly. This new standard requires hybrid and electric passenger cars, light trucks and vans LTVsand low speed vehicles LSVs to produce sounds meeting the requirements of this standard. Previously, the maximum allowable upward mounting angle was 15 degrees beyond vertical.

49 CFR 571.226 – Standard No. 226; Ejection Mitigation.

This final rule is a deregulatory action. The static deflection measurement is made with the ejection impactor extended mm outboard of the theoretical point of impact with the countermeasure and attached fmvss the ejection propulsion mechanismincluding any support frame and anchors. Continue checking all the targets listed in steps 1 through 4 of Table 1. In these tests curtain airbags are usually employed 2226 protective systems. Summary This document denies a rulemaking petition submitted by Mr.

At the time of launch the ejection impactor is rotated about the y axis of the ejection headform by rotating the headform positive z axis towards the vehicle positive x axis, in the increment determined to be necessary in S5.

Fmvse, we propose that the compliance date for the amendments in this rulemaking action would be days after the date of publication of the final rule in the Federal Register. Petitions for reconsideration of this final rule must be received not later than November 13, Ejection impactor means a device specified in S7.

The shaft is parallel to the y axis of the headform. The initial compliance date is September 1,with full phase in by September 1, The impactor and impact speed would simulate the 26 from an average size unrestrained adult male impacting a window on the opposite side of a large bus in a rollover. The force is applied once in each of the following headform axes: This document reopens the comment period for a notice ffmvss proposed rulemaking NPRM published January 28, The effective date of this rule is August 24, The petitioner claims that the recommended changes to 262 relevant safety standards would allow vehicle manufacturers to better utilize the regenerator technology to increase vehicle efficiency.

Inthe U. Place another secondary target center rearward of the forward primary target by two-thirds of the horizontal distance between the primary target centers and tangent with the lower portion of the offset-line see figure 4 figure provided for illustration purposes.

The actual implementation of the test, and the evaluation and documentation of results are also discussed. Petitions for reconsideration of this final rule must be received not later than March 2, We expect that, as a result of this joint rulemaking, virtually all of these vehicles would be limited to that speed.
