A retractor reel for a vehicle safety belt has a sensor responsive to the speed or acceleration of belt withdrawal to actuate a reel locking mechanism and also has a sensor responsive to vehicle acceleration or deceleration to actuate the locking mechanism. A solenoid actuated device is provided to retain both the sensors in the inoperative position. The reel can thus safely be used in an automatic seat belt arrangement of the type in which a carriage moves withdrawing belt from the reel to locate the belt in the operative position. |
