Abstract
A linear pretensioning drive for tightening a vehicle seat belt has a guide tube. A piston is located inside of the guide tube and can be driven along a longitudinal axis of the guide tube. A reverse movement lock is formed by balls that are arranged on a ring around the longitudinal axis of the guide tube. In the drive direction in front of the reverse movement lock at least one support part is provided which lies against the inner wall of the guide tube in the locking position with in each case a greater supporting surface than each ball of the reverse movement lock.
