Abstract (en)
[origin: WO0194164A1] A pretensioner (10) for a seat belt (12) employs a strap (30) fixed about a geared pulley (34) and also fixed at an opposite end (36) to a housing (18). Upon pretensioner activation, an actuator (20) is propelled through a rectangular passage (72) thereby impelling a portion (31) of the strap (30) extending across the passage (72). Torque created by the strap (30) about the pulley (34) effects rotary advancement of the geared pulley (34) with a geared clutch (37). The geared clutch (37) co-axially and rotatably communicates with a seat belt retractor spool (46) by a spool shaft (40) which axially extends through the clutch (37). Activation of the pretensioner (10) therefore results in ignition of a gas generant (16) that produces sufficient gas pressure to drive the actuator (20) through the linear passage (72), thereby effecting rotary movement of the pulley (34), the clutch (37), the shaft (40), and the spool (46) for tensioning the seat belt.
