A locking device is provided in a pre-tensioner for a safety belt or safety harness in a vehicle. The pre-tensioner is mounted on a plate(1) secured to the seat of the vehicle. In order to prevent the pre-tensioner being triggered by forward adjustment of the seat a plate(31) is provided which is pivotally(32) mounted, so that the plate can swing to a locking position on forward movement of the seat. When in the locking position an arcuate edge(33) of the plate is located adjacent a lever(11) forming part of the pre-tensioner preventing forward movement thereof and thus preventing triggering of the pre-tensioner. |
