This SAE Recommended Practice describes performance requirements for hardware used in motor vehicle seat belt assemblies when tested in accordance with the test procedures specified in SAE J140.
Test procedures and performance requirements for retractors will be covered in separate SAE Recommended Practices to be issued later.
Rationale
SAE J140 defines the test procedures for abrasion testing of the webbing used in seat belt assemblies. SAE J141 defines the acceptance requirements for these tests. The testing and test sequences are similar but not identical to what is defined in FMVSS 209 and TP-209. The legal requirements for web abrasion have been the same for many years. No evidence has been presented of any field concerns arising from shortcomings in the FMVSS and TP requirements.
It is proposed to revise SAE J140 and SAE J141 to make them consistent with the FMVSS and TP regulations, with some small exceptions. These exceptions are the changes and clarifications proposed by the AORC to NHTSA in December of 2008. It is expected that NHTSA will adopt the AORC proposals eventually.
Also, it is proposed to add web abrasion requirements to SAE J140 and SAE J141 for seat belt systems that do not use a manual adjusting latchplates. The existing abrasion requirements of SAE J140 and SAE J141 only include systems with manual adjusting latchplates. These devices are not used in most seat belts today. It is proposed to adopt the hex bar abrasion requirements of FMVSS 209 for seat belts that do not include a manual adjustable latchplate. It is reasonable to require some degree of abrasion resistance for seat belt webbing. No evidence has been presented to show that the current FMVSS abrasion standard is inadequate.
A clarification has been added so that it is understood that the manual adjust latchplate tilt lock requirements do not apply to semi cinching latchplates or dynamically cinching latchplates. Semi cinching latchplates are intended to meet the child seat locking requirements of FMVSS 208 S7.1.1.5, which can be met without passing the tilt lock test. Dynamically locking latchplates are intended to improve performance in NCAP or other crash testing. The locking requirements of such devices are best defined by the vehicle manufacturer to optimize performance in the specific applications.
The section of SAE J140/1 about attachment hook retention was deleted. Attachment hooks have not been used in light vehicles for many years. Similarly the section on lift buckles was also removed for the same reason. Section 4.5.2 does refer to ‘buckles of other types’ so there is a requirement for any potential future buckle release design. Also, FMVSS 208 S7.2d) requires that buckles be activated by push buttons.
The sections on buckle compression have been harmonized with FMVSS 209.
The requirement for web resistance to microorganisms has been deleted. It was included in the chart in SAE140 4.1 but not defined. All web in current use is made of synthetic fiber and not subject to the microorganism requirements of FMVSS 209.
A section defining the light resistance was added to J140 and J141. Light resistance was already in the chart in SAE J140 4.1, but the requirements were not defined. The light resistance requirements were taken from the AORC proposal of December 2008.
The role of the Motor Vehicle Council (MVC) is to serve industry, consumers, government, and the public by providing Technical Reports (Standards, Recommended Practices, and Information Reports) that will contribute to the improvement of the overall performance, convenience, and safety of passenger car and light truck transportation and assist in the development of vehicles, systems, and components. It is also the role of the MVC to strategically guide the development of such Technical Reports. It is not the purpose of the Council to regulate the manufacture or use of passenger cars and light trucks, and no specifications are to be promulgated which are arbitrary or more restrictive than necessary to achieve the above purposes. No specifications should deter the manufacture or use of adequate products, although specifications may differentiate products with different levels of performance, convenience, and safety. Implementation of any Technical Reports issued by the MVC is voluntary. Enforcement is not the intent of any SAE body. The SAE MVC, through its Committees, will actively attempt to harmonize its Technical Reports with standards of other agencies throughout the world. However, in these attempts, technical accuracy and SAE policies should be followed.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
