A seatbelt must be of a design suitable for the vehicle, and must be strong, secure and in sound condition.
Seatbelt webbing must not be cut, ripped, torn, frayed, faded or stretched. The webbing must not have unusual web patterns, must not be deformed, curled, rippled or have otherwise deteriorated, must be structurally sound and free of corrosion, so as not to reduce the performance of the seatbelt*
Seatbelt webbing must be securely attached to the tongue or the adjusting buckle and to any fittings that secure a seatbelt to the seatbelt anchorages.
The strands of the steel cables of a seatbelt stalk must not be damaged or have deteriorated, and the seatbelt stalk must not have any other weaknesses that could reduce its performance.
Seatbelt buckles, retractor mechanisms or any other fittings intended to ensure the safe use of the seatbelt must not have deteriorated below safe tolerance.
A seatbelt anchorage and its mounting location:
must be of a strength appropriate to both the motor vehicle and the attached seatbelt
must be structurally sound and free of corrosion, and
must not be damaged or distorted.
When a seatbelt or part of a seatbelt is integral to a seat, the seat and seat anchorages must be compatible in strength with the seatbelt or with that part of the seatbelt attached to the seat.
