Abstract: A safety seatbelt system which automatically provides a safety seatbelt around a passenger when he takes a seat in a vehicle and closes a door. Once the seatbelt is put around the passenger, he cannot remove the seatbelt while driving the vehicle. This system comprises a hand brake switch and a hand brake switch relay, and a solenoid magnetizing circuit for supplying magnetizing current to a solenoid to prevent the seatbelt from being hooked and removed from the passenger as long as the hand brake is released, said solenoid magnetizing circuit forming a second solenoid operating system.

Abstract: A seat belt retractor having a main locking pawl for engaging the ratchet wheel on the reel to prevent the belt from being pulled out and a second pawl and ratchet responsive to either acceleration of the sensing pendulum or the inertia of an inertia assembly which senses acceleration of the reel when the belt is pulled out is disabled from being locked, thereby permitting the belt to be pulled out freely, by a blocking member which engages the second pawl to keep it from engaging the second ratchet and a device or system for moving the blocking member into and out of engagement with the second pawl. The invention is especially useful for door-mounted retractors used in connection with a passive seat belt restraint system.

Abstract: The invention provides an inertia locking seat belt retractor for winding a shoulder belt having one end mounted on the vehicle door so that door movement moves the belt between stowed and restraining positions. The retractor has a winding prevention mechanism including a pawl and ratchet operable by a prior known control means to selectively lock the retractor against belt winding to hold the belt extended at a set slackened length with respect to the occupant. The improvement is comprised of a cam member which is rotatably mounted and has a cam surface which blocks movement of the pawl to the locked condition irrespective of the control means. The cam member also has a notch which allows the pawl to move to the locked condition with the ratchet. The cam member is coupled to the reel by a reduction gear set which causes the cam member to revolve less than one revolution during a plurality of reel revolutions upon movement of the belt between the fully wound and fully unwound conditions.

Abstract: A retractor device for a seat belt mechanism, comprising a ratchet wheel mounted on a reel shaft for reeling a seat belt, a pawl engageable with the ratchet wheel, a belt stop member disposed opposite to an abutment surface on a casing, guide slots in the casing and emergency operating means sensible to an emergency condition of a vehicle. Said means is operable to engage the pawl with the ratchet wheel to prevent rotation of the shaft and to move the stop member along the slots in a direction of drawing of the belt to clamp the latter between the stop member and the abutment surface, thereby preventing the drawing of the belt due to tightening thereof.

Abstract: A seat belt inhibitor system is designed to prevent door mounted inertial seat belt retractor 14 from locking the seat belt webbing 13 whenever the door is opened. The retractor pendulum 31, sensitive to acceleration, moves the locking bar 28 upward locking the retractor and prevents the belt webbing from paying out. An electromagnet 36, when energized, attracts a leaf spring 37 extending from the locking bar inhibiting movement of the latter. System inhibiting is initiated by closing either a door latch switch 42 or a door release handle switch 41. At low accelerations (occurring while the door is being opened), the locking bar 28 is restrained by the electromagnet 36 through the leaf spring 37. If the system should fail such that the electromagnet was energized while the door is closed, high acceleration of the pendulum would force the locking bar up, locking the retractor. Deenergizing occurs normally whenever the door is closed.

Abstract: A retractor for seat belt provided with an emergency locking mechanism is disclosed. The retractor comprises a webbing taking-up means, an inertia sensing means, a locking means and an operating means. The inertia sensing means directly senses by means of inertia a change in speed of vehicle when the change of vehicle speed exceeds a predetermined level. When the inertia sensing means senses such change of vehicle speed beyond the predetermined level, the locking means interlocked with the inertia sensing means is brought into operation to lock the pulling out of the webbing from the webbing take-up means. The operating means is movable between a first position in which it allows a free movement of the locking means and a second position in which it restrains the movement of the locking means. When there is no need for emergency locking, the operating means is held in its second position by an external order issued from the outside of the retractor.
