Safety belt roll-up device with a locking pawl mechanism to engage locking teeth of a locking wheel in fixed connection with the belt shaft. The pawl mechanism has a double locking pawl having two pawl levers, rotatably mounted on a common pivot axis. Each lever has a pawl tooth for engagement with the locking wheel. The two pawl teeth are spaced a distance which is different than the pitch of the locking teeth of the locking wheel or a multiple thereof. A release mechanism, upon the vehicle exceeding permissible limit of acceleration or deceleration, activates the pawl to move into locking engagement. By virture of the two pawl levers in the locking mechanism combination of the invention, a pawl tooth hitting the point of the tooth of the locking wheel and bouncing off, results in immediate engagement of the other pawl tooth with a locking tooth of the locking wheel. |
