14. The pretensioner according to claim 13, wherein a lateral side of the seatbelt is folded under a central portion of the seatbelt where the seatbelt extends out of the exit.
15. The pretensioner according to claim 13, wherein at least a portion of the seatbelt is folded back upon itself as it extends about the piston.
16. The pretensioner according to claim 1, wherein the opening of the seatbelt guide includes an upper wall, a lower wall and opposed sidewalls generally forming a flattened funnel shape proceeding from the entrance to the exit, the lower wall having a projection extending upward toward the upper wall and the projection extending one of perpendicularly or obliquely relative to the lower wall.
17. The pretensioner according to claim 16, wherein the opposed side walls are one of asymmetrically or symmetrically shaped.
18. The pretensioner according to claim 16, wherein the opposed sidewalls include shoulders formed therein and extending longitudinally in the opening, the shoulders defining a reduced region between the opposed sidewalls.
19. The pretensioner according to claim 18, wherein adjacent to the entrance the opposed side walls include portions formed without shoulders.
20. The pretensioner according to claim 13, wherein the opening defines one of a funnel shape or a flattened funnel shape.
