5 Point / 6 Point Harness: A seatbelt with 5 or 6 belts in total. It restrains the movement of the occupant more than a 3 Point Seatbelt and is safer 5 Point Harness  1 & 2: Shoulder Belts 3 & 4: Lab Lap Belts 5: Anti Sub Belt
6 Point Harness Passthroughs: Cutouts in the seat to allow the belts of a 5 or 6 Point Harness to pass through the seat uninterrupted (as shown by the red circles in the image below)
Seatback: The portion of the seat which supports the back and shoulders of the occupant Headrest: The portion of the seat which supports the head and/or neck of the occupant Seatpan: The portion of the seat which supports the buttock and upper leg of the occupant Bolsters: Protrusions/barriers typically found on the seatback or seatpan of the seat (shown by the red circles in the image below) They keep the occupant centered in the seat during cornering.
Undepressed Seat Contour: The shape of the seat cushioning (typically viewed from the side) when no occupant has sat in it Depressed Seat Contour: The shape of the seat cushioning (typically viewed from the side) when an occupant is sitting in the seat - causing the cushioning to compress ILD/IFD: Acronym for Indentation Load Deflection or Indentation Force Deflection. A test to determine the stiffness of a foam. Manufacturers will typically specify the stiffness of their foam in ILD/IFD In this test a circular flat indenter is pressed against a foam sample of standardized width, length and height. 60 seconds after the indenter has achieved 25% or 50% compression, the force is measured Higher ILD/IFD values = stiffer foam 25% ILD/IFD is for a 25% compression 50% ILD/IFD is for a 50% compression US measurements are in pound-force European measurements are in newtons
