Abstract: A seat belt height adjuster for anchoring a seat belt is provided in a preferred form with three relatively simple component parts comprising a slider, a rail, and a bent spring. One end of the slider is biased by the bent spring so that a portion of the slider is spaced from the rail and to position locking protrusions on the slider body into at least one opening in the rail to lock the height adjuster at the desired height position. To adjust the location of the slider along the rail, a pushing force on the one end of the slider compresses the spring and removes the locking protrusions from the rail opening thereby allowing sliding of the slider along the rail. The slider pivots about its other end which is engaging the rail. Upon release of the pushing force, the spring expands and biases the locking protrusion into a rail opening. The spring may be a simple V or U-shaped, leaf spring and the slider may be a single, integral piece of metal.

Abstract: A buckle support assembly is provided including an anchor member and a buckle with a support member extending therebetween. A sleeve member is supported in position to extend between the anchor member and buckle and about the support member via interfering portions of the anchor member and sleeve member. Preferably, the interfering portions include small tabs of the anchor member and internal ribs of the sleeve member.

Abstract: A low cost pretensioner is provided by using an ignitable charge and initiator integrated with a piston which is disposed in a cylindrical metal tube that has a common straight gas generation and piston travel bore so that a inexpensive metal tube rather than a complex casting can be used. A cable is connected at one end to the piston and passes through a cable deflection device having a locking device for locking the cable against travel in a reverse direction after tightening the seat belt system. The locking device may be an inexpensive, one-piece wedge-shaped clamping or gripping device which transfers the high tensile forces from the passenger's body pulling on the cable through the deflection device to a vehicle anchorage rather than through a locking device which is disposed within the cylinder tube which must have tube walls sufficiently strong to withstand such high tensile forces.

Abstract: A vehicle restraint system provides the seat occupant with options for three-point, four-point and five-point seat belt configurations. In one embodiment, the restraint system includes two three-point seat belt systems arranged as mirror images and a two position buckle located along the center line of the seat cushion.

Abstract: A seat belt system, in one form, includes a buckle anchored along the side of the seat, a tongue slidably mounted on the seat belt for being latched in the buckle to define the shoulder and lap belt portions, and a retractor for pay in and pay out of the seat belt into and out from the retractor. The airbag is fixed to the tongue and configured for sliding along the seat belt so that with the tongue latched in the buckle the airbag extends along the same position irrespective of the size of the occupant. Alternatively, the airbag is fixed to a guide loop adjacent to the shoulder of the occupant and configured to allow for sliding of the seat belt relative thereto so that with the tongue latched in the buckle the airbag extends from the same position and across the occupant's torso irrespective of the size of the occupant.

Abstract: A system and method are provided for cancelling out downward directed tension forces generated on an object on a vehicle seat. In active, door-mounted seat belt systems, the belt tension force cancellation system includes a simulator that is operable to transfer upward forces on a door-mounted, lower anchor to the vehicle seat without requiring a permanent anchor point for the seat belt in the vehicle compartment. The simulator can either automatically transfer the forces upon securing the belt about the object, or be selectively operable.

Abstract: A seat belt anchor device and method are provided for anchoring a seat belt to a stud. The device includes a plate member having a keyhole opening into which the stud is fit with the plate member pulled upwardly to bring the stud to the installed position relative to the plate member. A spring retainer member keeps the stud and plate member in their installed position. A stop is provided to limit pivoting of the spring retainer member relative to the plate member. In some forms, the spring retainer includes resilient clamping portions for clamping engagement with the stud head therebetween in the installed portion.

Abstract: A test system is provided for simulating pre-tensioner systems that use pyrotechnic gas generators. In a preferred form, the test system includes a pneumatic cylinder energized by pressurized air from an accumulator and passing through a fast acting ball valve. A substantially linear relationship is established between accumulator pressure and the time rate of change of acceleration of a piston in the pneumatic cylinder. Use of the test system allows improved evaluation of seat belt systems employing pre-tensioners with pyrotechnic gas generators.

Abstract: An interlock system for stopping seat belt payout from a retractor when a seat is not secured is provided. The interlock system includes a connector between the seat latch and the retractor with the connector operating a retractor locking actuator which utilizes the vehicle inertia sensor to cause retractor locking. In one form, the actuator is shifted into engagement with the inertia member for retractor locking when the seat is released. In another form, the actuator is mounted to a module secured on one side of the one of the retractor frame plates to which the actuating mechanism for the vehicle sensor is secured on the other side thereof. The connector causes shifting of the actuator member from the one side to the other to operate the vehicle sensor actuating mechanism for retractor locking when the seat is released.

Abstract: A buckle presenter system is provided that shifts the buckle to a more accessible latching position for latching with a tongue plate or tip and then shifts the latched buckle to a performance position for achieving the desired performance. This is achieved by sensing the occupant's need for latching the buckle as when the occupant enters the vehicle and is seated and then automatically shifting the buckle to a latching position for providing better accessibility for inserting the latch plate into the buckle and then automatically returning the latched buckle to the performance position.

Abstract: A seat belt system is provided for use in the rear seating area of a vehicle. The system has first and second tongue and buckle sets that are identical on outboard seats or either side of the center seat. The first and second sets are for use with a standard three-point shoulder and lap restraint system. The center seat also has a three-point restraint system but uses third and fourth tongue and buckle sets therefor with both tongues mounted to a single length of belt so that when disconnected from their corresponding buckles, the center seat back rest can be pivoted down without interference from the center seat belt restraint system. In addition, the tongues will only releasably lock in their corresponding buckles. To this end, the fourth tongue and buckle have a key and keyway mating fit to prevent the fourth tongue from locking in the other buckles.

Abstract: A vehicle-sensitive retractor is provided that can be mounted in a reclinable seat back which has a nominal position inclined to the vertical and that is actuated to a locked position in each of three mutually-perpendicular planes. The retractor has a universal acceleration sensor that compensates for different seat back inclinations so that it does not lock until a threshold vehicle acceleration condition is detected, and so that it will lock regardless of the sensed acceleration when the seat back and retractor are shifted to specified inclinations forward and rearward from the seat back nominally inclined position. The sensor preferably includes a weighted basket that supports an inertia member. At the rearward inclination position, the inertia member operates an actuating mechanism to lock the retractor. A stop engages and prevents adjustment of the support at the seat back's forwardmost inclined position so that at a predetermined angular distance forward therefrom, e.g.

Abstract: A safety belt tensioner is provided for pulling a buckle part to tighten a safety belt system about an occupant. The tensioner includes a flexible member or cable having a first loop connected to the buckle part which pulls the buckle part when it is shortened, as by actuation of a power operated device such as a piston-cylinder device. To shorten the piston stroke while achieving the necessary displacement of the buckle part, the flexible member is provided with a second loop connected to the piston about a turning member thereof with one end of an anchored half of the second loop secured to a stationary part of the pretensioner, and the other loop half extending from the cylinder and connected to the portion of the flexible cable member for the buckle part. This provides about a 1:1 ratio between the length of piston travel and downward travel of the buckle part to minimize the piston travel to allow the length of the cylinder to be shorter for providing a more compact pretensioner.
