Abstract
A device to prevent undesirable paying out under excess loading of a strop forming part of a load restraining means (including vehicle seat belts or safety harness) comprises a housing for receiving an intermediate part of a strop and including a roller around which the strop is guided. The roller is mounted so that it becomes dislodged when tension in the strop exceeds a predetermined value and the strop becomes trapped between the roller and a part of the guidance means which is curved in the opposite sense to the roller in order to produce a gradual stress gradient in the strop to reduce risk of parting. The roller is supported on bushes engaging chamfered apertures in flat washers and which will disengage under excessive resultant force on the roller. Slots cut into the ends of the rollers define teeth which serve to support the roller on cam members formed integrally with the housing with lobes which enter the slots on roller displacement.
