NHTSA TEST PROCEDURE

Initial setup:

Sliding seat 265 mm from honeycomb.

CRS should be placed on the sliding seat 300 mm from edge (centered with the latch anchors). Seat should be installed according to the directions from the manufacturer.

Install child dummy with the upper arms aligned with the torso, and the hands resting on CRS seat cushion. Route the data umbilical along the side of the dummy’s upper leg, between the dummy and the CRS side interior. Position dummy so that the full torso is in contact with the back of the seat and top of head should be aligned with the target on the top and bottom of the CRS. Using the flat square surface of a force gauge, apply a force of 177N (40 lbs) perpendicular to the back of the CRS, first against the dummy’s lower pelvis and then at the dummy’s thorax on the mid-sagittal plane of the ATD. Tighten the CRS internal harness (1 ½ to 3 lbs). Tighten and check loads of the lower latch anchors (12-15 lbs) and top tether (approximately 9-12 lbs, where applicable).

CRS

0 pt

Dimensions should be taken at 0 point, which is located at the corner of the steel plate that represents the door.

CRS Measurements Top of seat to wall Bottom of seat to wall Side base of seat to wall Side wing to wall

Dummy measurements Top of head to wall Head CG to wall Front of face (center target) to wall Center of Knee to Center of Knee spacing should be150 + 13 mm

Measurements shall also be dimensioned using a CCM (i.e. FARO arm) for repeat testing. See Attachment #5.

Post Test Measurements need to be taken from the seat edge to honeycomb.

Photography/Video Coverage:

Pre/Post Test photos of all sides and overhead of sled buck +CRS with placard in view Pre Test close-up of CRS- Document where all targets are on CRS Manufacture Label (s) Pre/Post Test close-up of dummy in CRS Post Test chalk marks on seat and door Post Test of honeycomb crush Post Test any damage CRS Post Test any damage to sled buck (cushions, rail)

Document test with high speed videos (1000 frames/sec) Overhead view- wide and tight Front View perpendicular to the plane of the sliding seat movement

- View of overall sled and CRS kinematics See below for placard info and front view

NOTE: For rear-facing CRS tests camera views need adjusting and documentation. Also, additional contact tape is required to determine contacts, etc.
