A pretensioner 10 for a seat belt 12 employs a strap 30 fixed about a pulley 34 and also fixed at an opposite end 36 to a housing 18. Upon pretensioner activation, an actuator 20 is propelled across a rectangular passage 72 thereby impelling a portion 31 of the strap 30 extending across the passage
A pretensioner 10 for a seat belt 12 employs a strap 30 fixed about a pulley 34 and also fixed at an opposite end 36 to a housing 18. Upon pretensioner activation, an actuator 20 is propelled across 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 engaged therewith. The geared clutch 37 co-axially and rotatably communicates with a seat belt retractor spool 46 wherein a seat belt retractor spool shaft 40 axially extends through the clutch 37 and spool 46. 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 a linear passage 72, thereby effecting rotary movement of the pulley 34, the clutch 37, the shaft 40, and the spool 46. A seat belt 12 wound about the spool 46 is thereby pretensioned.

Rotation of the tape reel in one direction causes the engaging portions to feed the protrusions, whereby the leader_tape is sent out from the cartridge. The tape cartridge can be reliably mounted to a recording/reproducing apparatus. erein each of said grooved transfer sheaves is mounted to said support member by an axle pin, and said retainers are mounted to said axle pins of respective grooved transfer sheaves to thereby mount said retainers to said support member. 13. The sheave assembly according to claim 12, wherein said support member supports two of said grooved transfer sheaves at opposed ends of said support member defining end grooved transfer sheaves, said respective retainers comprising end retainers and being mounted to said axle pins of said end grooved transfer sheaves. 14. The sheave assembly according to claim 7, wherein said support member supports two of said grooved transfer sheaves at opposed ends of said support member defining end grooved transfer sheaves and at least two other of said grooved transfer sheaves at intermediate portions of said support member defining intermediate grooved transfer sheaves, two of said retainers supported at said end grooved transfer sheaves defining end retainers, and another of said retainers supported at least one of said intermediate grooved transfer sheaves defining an intermediate retainer. 15. The sheave assembly according to claim 14, wherein portions of said support member form said end retainers. 16. The sheave assembly according to claim 14, wherein said retaining members are mounted to said support member. 17. The sheave assembly according to claim 16, wherein said end retainers comprise generally U-shaped members. 18. The sheave assembly according to claim 14, wherein said intermediate retainer is mounted to a pair of said intermediate grooved transfer sheaves. 19. The sheave assembly according to claim 18, wherein said intermediate retainer member comprises an elongate member having a pair of mounting openings for mounting said intermediate retainer member to axle pins of said pair of intermediate transfer sheaves. 20. A sheave assembly of a transfer assembly, said transfer assembly for transferring one or more articles laterally with respect to a conveying surface, said sheave assembly comprising: a support member; a transfer belt; and a plurality of grooved transfer sheaves mounted to said support member, each of said grooved transfer sheaves having a groove, said transfer sheaves supporting said transfer belt in said grooves, said transfer belt defining a transfer conveying surface, and said support member including a plurality of retainers to laterally retain said transfer belt in said grooves of said transfer sheaves when said transfer belt is subject to a lateral force from an article being transferred by said transfer belt, said retainers being mounted to said support member, each of said grooved transfer sheaves being mounted to said support member by an axle pin, said retainers being mounted to said axle pins of respective grooved transfer sheaves to thereby mount said retainers to said support member, said support member supporting two of said grooved transfer sheaves at opposed ends of said,support member defining end groove sheaves, said respective retainers comprising end retainers and being mounted to said axle pins of said end grooved transfer sheaves wherein said end retainers straddle said end grooved transfer sheaves. 21. The sheave assembly according to claim 20, wherein each of said end retainers comprises a U-shaped member including opposed facing side members, said opposed facing side members each including a mounting opening for receiving said axle pin of a respective end grooved transfer sheave. 22. The sheave assembly according to claim 21, wherein at least one of said mounting openings comprises an L-shaped slot. 23. The sheave assembly according to claim 22, wherein both of said mounting openings comprise L-shaped slots whereby said U-shaped member can be installed after said respective end grooved transfer sheaves are mounted to said support member. 24. A sheave assembly of a transfer assembly, said transfer assembly for transferring one or more articles
