Seat belt system with dual payout retractor

摘要

A seat belt system (10) includes a lap belt (60) including a first portion (74) and a second portion (85). A retractor (76) includes a spool (96) rotatable about an axis (160). The first and second lap belt portions (74, 85) are secured to the spool (96). The spool (96) is biased to rotate in a first rotational direction to wind the first and second portions (74, 85) onto the spool. The first and second portions (74, 85) when tensioned urge the spool (96) to rotate in a second rotational direction opposite said first rotational direction to unwind the first and second portions from the spool. A locking mechanism (170) is actuatable to lock the spool (96) against rotation in the second rotational direction. First and second web grabbing devices (180, 182) are actuatable to clamp onto the first and second portions (74, 85) when the locking mechanism (170) is in the locked condition.
