Bill of materials
- B0 headBody B
- B1 torsoB lumbar on ground
- B2 / B3 femursB hip flexion and abduction
- A0 / A1A torso inclined over B1
- A2A kneeling column
- Groundbed
Procedure
- Body B shall be supine. Lumbar of B1 on ground.
- Body B should flex both hips until B2/B3 are near vertical. Remaining DOF at each hip: abduction.
- Abduct B2 and B3 until A fits the interval without compressing B femurs against A torso.
- Body A shall kneel in that interval. Load path: A knees to ground.
- Incline A1 toward B0. Seat the pelvic contact. θ is B hip flexion; more flexion raises θ and can reduce penetration if the femurs close the gap.
- Hands may close an A/B loop for lateral stability.
