Section 571.210 - Standard No. 210; Seat belt assembly anchorages

S1.Purpose and scope. This standard establishes requirements for seat belt assembly anchorages to insure their proper location for effective occupant restraint and to reduce the likelihood of their failure.

S2.Application. This standard applies to passenger cars, multipurpose passenger vehicles, trucks, buses, and school buses.

S3.Definitions.

Actuator means the device used to apply the load in performing testing.

Bridged pull yoke means the yoke that bridges the torso and pelvis on the FAD1 or FAD2 and is used for testing Type 1 seat belt assemblies.

FAD means the force application device, either the FAD1 or the FAD2, a one-piece device consisting of an upper torso portion and a pelvic portion hinged together.

FAD1 means the larger version of the force application device specified in drawings NHTSA221-210-01, "Drawing Package for the Force Application Device 1 (FAD1)," April 9, 2024 (incorporated by reference, see § 571.5 ). FAD1 is depicted in figure 7 to this standard (figure provided for illustration purposes).

FAD2 means the smaller version of the force application device specified in drawings NHTSA221-210-01J, "Drawing Package for the Force Application Device 2 (FAD2)," April 9, 2024 (incorporated by reference; see § 571.5 ). FAD2 is depicted in figure 8 to this standard (figure provided for illustration purposes).

Midsagittal plane means the vertical plane that separates the FAD into equal left and right halves.

School bus torso belt adjusted height means the vertical height above the seating reference point (SgRP) of the horizontal plane containing a segment of the torso belt centerline located 25 mm to 75 mm forward of the torso belt height adjuster device, when the torso belt retractor is locked and the torso belt is pulled away from the seat back by applying a 20 N horizontal force in the forward direction through the webbing at a location 100 mm or more forward of the adjustment device as shown in Figure 5.

School bus torso belt anchor point means the midpoint of the torso belt width where the torso belt first contacts the uppermost torso belt anchorage. Seat belt anchorage means any component, other than the webbing or straps, involved in transferring seat belt loads to the vehicle structure, including, but not limited to, the attachment hardware, seat frames, seat pedestals, the vehicle structure itself, and any part of the vehicle whose failure causes separation of the belt from the vehicle structure.

Seat reference plane means the vertical plane that passes through the "seating reference point" (as defined at 49 CFR 571.3 ) and is parallel to the direction that the seat faces.

Small occupant seating position is as defined in 49 CFR 571.222 .
