PRETENSIONING BUCKLE

摘要

A safety system has a buckle (22) secured to a pretensioner (20). The pretensioner (20) has a stationary link (102) and stationary block (110). A housing is slidably received upon the stationary link (102) and is movable relative to the stationary block (110). A pressure unit for causing the housing and a buckle which is operatively attached to the housing, to move downwardly relative to the stationary block to thereby eliminate slack in a seat belt. A second link (104) is received through the housing for preventing rotation of the housing about the first link (102).
