              2.2. Belt type
               Belts of different "types" are belts differing substantially from one another; the differences may relate in particular to:
              2.2.1. Rigid parts (buckle, attachments, retractor, etc.);
              2.2.2. The material, weave, dimensions and colour of the straps; or
              2.2.3. The geometry of the belt assembly.
              2.3. Strap
               A flexible component designed to hold the body and to transmit stresses to the belt anchorages.
              2.4. Buckle
               A quick-release device enabling the wearer to be held by the belt. The buckle may incorporate the adjusting device, except in the case of a harness belt buckle.
              2.5. Belt adjusting device
               A device enabling the belt to be adjusted according to the requirements of the individual wearer and to the position of the seat. The adjusting device may be part of the buckle, or a retractor, or any other part of the safety-belt.
              2.6. Pre-loading device
               An additional or integrated device which tightens the seat-belt webbing in order to reduce the slack of the belt during a crash sequence.
              2.7. "Reference zone" means the space between two vertical longitudinal planes, 400 mm apart and symmetrical with respect to the H-point, and defined by rotation from vertical to horizontal of the head-form apparatus, described in Regulation No. 21 Annex 1. The apparatus shall be positioned as described in that annex to Regulation No. 21 and set to the maximum length of 840 mm.
              2.8. "Airbag assembly" means a device installed to supplement safety-belts and restraint systems in power-driven vehicles, i.e. system which, in the event of a severe impact affecting the vehicle automatically deploys a flexible structure intended to limit, by compression of the gas contained within it, the gravity of the contacts of one or more parts of the body of an occupant of the vehicle with the interior of the passenger compartment. Any such described deployed structure shall not be considered as a rigid part.
              2.9. "Passenger airbag" means an airbag assembly intended to protect occupant(s) in seats other than the driver's in the event of a frontal collision.
              2.10. "Child restraint" means a safety device as defined in Regulation No. 44 or Regulation No. 129.
              2.11. "Rearward-facing" means facing in the direction opposite to the normal direction of travel of the vehicle.
              2.12. Attachments
               Parts of the belt assembly including the necessary securing components, which enable it to be attached to the belt anchorages.
              2.13. Energy absorber
               Device designed to disperse energy independently of or jointly with the strap and forming part of a belt assembly.
              2.14. Retractor
               Device to accommodate part or the whole of the strap of a safety-belt.
              2.14.1. Non-locking retractor (type 1)
               A retractor from which the strap
