Abstract
A locking mechanism for a seat belt has a case, a locking set and a pretensioner. The case is mounted adjacent to a side of a retractor having a shaft and the case is mounted around the shaft and has a mount inside the case and at least one opening being formed on the bottom. The mount has at least one hole formed therethrough. The locking set is mounted on the shaft. The pretensioner has a steel ball and a rod. The steel ball is detachably disposed on the mount and the rod is pivotally mounted in the case and is disposed on the steel ball. If muddy water, sand or dirt enters the locking mechanism, muddy water, sand or dirt can fall through the at least one hole of the mount and the at least one opening thus avoiding muddy water, sand or dirt affecting the locking mechanism.
