Automatic Locking Retractor Seat Belts Commonly referred to as ALR seat belts. Available in webbing widths of 2 inches (50mm) or 3 inches (75mm).
An ALR type seat belt may be used in industrial vehicle applications such as mining, agricultural, earth-moving and forklift equipment. These retractable seat belts are not angle sensitive. Instead the seat belt locking mechanism is activated automatically when the webbing is extended beyond the locking point and the tongue is inserted into the buckle. A cam action within the retractor then locks the retractor from unwinding further. Webbing can only spool onto the retractor. This locks the operator into the vehicle seat and restricts undesired occupant movement over rough terrain. Releasing the tongue from the buckle allows the retractor to fully retract, in turn unlocking the retractor.
