Regulation 16.08 Consolidated to Supplement 2 Safety belts, ISOFIX and i-Size（Part 2）
- DEFINITIONS
2.1. Safety-belt (seat-belt, belt)
An arrangement of straps with a securing buckle, adjusting devices and attachments which is capable of being anchored to the interior of a power-driven vehicle and is designed to diminish the risk of injury to its wearer, in the event of collision or of abrupt deceleration of the vehicle, by limiting the mobility of the wearer’s body. Such an arrangement is generally referred to as a “belt assembly”, which term also embraces any device for absorbing energy or for retracting the belt.
The arrangement can be tested and approved as a safety-belt arrangement or as a restraint system.
2.1.1. LAP BELT

2.1.2. DIAGONAL BELT
A belt which passes diagonally across the front of the chest from the hip to the opposite shoulder.
2.1.3. THREE-POINT BELT
A belt which is essentially a combination of a lap strap and a diagonal strap.
2.1.4. S-TYPE BELT
A belt arrangement other than a three-point belt or a lap belt.
2.1.5. HARNESS BELT
A S-type belt arrangement comprising a lap belt and shoulder straps; a harness belt may be provided with an additional crotch strap assembly.
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

The apparatus shall be positioned as described in that annex to UN 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.
