A pretensioner (6) for tightening an occupant restraint, such as a seatbelt (16), against an occupant on a vehicle. The pretensioner has a locking reel (8) which is activated when a signal is sent by a crash sensing device (2). When such signal is sent, the pretensioner causes a rack (36) to turn a pinion (40), which is attached to a reel which tightens the occupant restraint. The pinion is allowed to turn freely by holding the rack out of its sphere of movement until the piston (28), which controls the position of the rack, is caused to extend. The pinion turns a shaft (62) which is connected to a locking reel through a connector (44) which is movable between a connected configuration and a disconnected configuration.

Ce prétensionneur (6) reprenant la tension d'une ceinture de sécurité (16), par exemple, immobilise sur son siège l'occupant d'un véhicule. Il est muni d'un enrouleur (8) permettant une immobilisation actionné à réception d'un signal envoyé par un détecteur d'impact (2). Lorsque ce signal est envoyé, le prétensionneur entraîne une crémaillère (36) qui fait tourner un pignon d'engrenage (40) relié à l'enrouleur afin de reprendre la tension du système de retenue. Le pignon d'engrenage peut tourner librement lorsque la crémaillère est maintenue en dehors de sa zone de déplacement jusqu'à ce que le piston (28) qui commande la position de la crémaillère se déploie. Le pignon d'engrenage fait tourner une tige (62) reliée à l'enrouleur par un connecteur (44) se déplaçant entre une position de connexion et une position de déconnexion.
