Abstract
Disclosed is an improved reel assembly for use in conjunction with an occupant restraint system. The assembly employs a dual locking arrangement whereby an occupant can be restrained during both major and minor incidents. After a minor incident, the reel assembly can be conveniently unlocked, without the need for accessing the push button, by applying counter tension to the webbing. After a major incident, the reel assembly remains locked until the occupant disengages the reel via a push button. When the reel assembly experiences the force of a major incident, rotation of the webbing shaft may be first partially arrested by the engagement of a first of two locking teeth on a locking dog with a first of two engagement surfaces on a geared end plate and subsequently completely arrested by the combined engagements of the first and second locking teeth with their respective first and second engagement surfaces.
