Auto Lap Straps

Not normally a common choice for cars when thinking of replacing a seat belt, but automatic lap style seat belts may have a use in certain applications. ALR’s are Auto Locking Retractors, and when worn they are fixed belts, so they cannot be pulled out once you have put the seat belt on.

ALR Seat Belts

An ALR uses a mini retractor with a locking device. Unlike a normal automatic seat belt, they do not have a webbing sensitive locking device. The locking device is triggered once you have pulled more than 300mm (12 inches) of webbing from the reel. You can continue to pull the webbing out as long as you do not allow even a mm to go back into the reel. Once you let, the webbing to retract you cannot pull anymore webbing out until you let the webbing completely retract and then start again. Thus when worn they act in the same way as a standard lap belt. They are available with either Period or Modern buckles.
