This is a typical lap belt style latch assembly. It locks and unlocks the lap belt strap hardware using the pivot lever handle. The shoulder harness straps and submarine straps also clip into the latch assembly, making them easy to assemble with the single latch, and easy to exit as well. Cam-lock systems are also available. These are premium latch systems that provide even greater speed and convenience of latch exit by releasing all straps in the harness simultaneously.
