  • Safety device for vehicles
    Patent number: 4445648
    Abstract: A safety device for vehicles includes a safety belt for restraining a passenger in a normal position in a seat. A winder is attached to one end of the safety belt and winds the end of the belt onto a winding roller. A blocking device is actuated to prevent the winder from rewinding the belt when the passenger remains in the normal position in the seat and the belt is buckled. A release is provided for disconnecting the blocking device from the locking position when an excessive amount of slack develops in the belt, so that the winder can take up the excessive slack.
