§572.188   Pelvis.

(a) The pelvis (175-6000) is part of the torso assembly shown in drawing 175-0000. The pelvis is equipped with a pubic symphysis load sensor in conformance with §572.189(f) and mounted as shown in drawing (175-0000 sheet 4). When subjected to tests procedures specified in paragraph (b) of this section, the pelvis assembly shall meet performance requirements specified in paragraph (c) of this section.

(b) Test procedure.

(1) Soak the dummy assembly (175-0000) without suit (175-8000) and shoulder foam pad (175-3010) as specified in §572.189(n);

(2) The dummy is seated as specified in Figure U6 in appendix A to this subpart;

(3) The pelvis impactor is the same as specified in §572.189(a);

(4) The impactor is guided, if needed, so that at contact with the pelvis its longitudinal axis is within ±0.5 degrees of a horizontal plane and perpendicular to the midsagittal plane of the dummy and the centerpoint on the impactor's face is within 5 mm of the center of the H-point in the pelvis, as shown in Figure U6 in appendix A to this subpart;

(5) The impactor impacts the dummy's pelvis at 4.3 ±0.1 m/s.

(6) Time zero is defined in §572.189(k).

(c) Performance criteria. (1) The impactor force (probe acceleration multiplied by its mass) shall be not less than 4,700 N and not more than 5,400 N, occurring between 11.8 ms and 16.1 ms from time zero;

(2) The pubic symphysis load, measured with load cell specified in §572.189(f) shall be not less than 1,230 N and not more than 1,590 N occurring between 12.2 ms and 17.0 ms from time zero.
