ABSTRACT:
An emergency locking passenger seat belt retractor is fitted with a pyrotechnic pretensioner actuator (221) which acts via a cable wound on a drum (213), the drum being located on frangible supports in a clutch housing and having internally formed cam surfaces which can act upon frangibly supported intermediate rollers (215) to displace them generally radially inwards to drivingly engage a part of the webbing reel to tighten the belt. Advantageously the drum and the locking rollers are supported on frangible pegs moulded with shim or plate members (222a, 222b), disposed on each side of the drum (213).
