Electrically activated tension eliminator actuator

摘要

A vehicle occupant operated device for selectively eliminating the rewinding tension in a seat belt retractor mechanism. The automobile battery is operably coupled to the device, using an occupant controlled switch to a combination limit and reversing switch. The limit switch is coupled to a permanent magnet, d-c, reversing motor. Through reduction gearing, the motor shifts a rod-like member which is adapted to actuate a tension eliminator mechanism within the seat belt retractor between two positions, one in which rewinding tension imparted to the seat belt is allowed, the other in which said tension is eliminated.
