A seat belt system for use in a vehicle, which includes a seat belt webbing for restraining an occupant of the vehicle, wherein the webbing includes a first end and a second end, wherein the first end of the webbing is attached to a retractor for either retracting the webbing or permitting withdrawal of the webbing, and wherein the second end of the webbing is connected to an anchor; a tongue mechanism connected to the webbing and positioned to separate the webbing into a lap portion and a shoulder portion; and a buckle mechanism configured to detachably couple with the tongue mechanism. The tongue mechanism is configured so that the tongue mechanism is slideably coupled to the webbing when the tension in the webbing is less than a cinching load, and when the tension in the webbing is equal to or greater than the cinching load the tongue mechanism applies a cinching force on the webbing to prevent the webbing from changing position relative to the tongue mechanism. The tongue mechanism is further configured so that when the tension in the webbing is less than the cinching load there is no cinching force applied to the webbing.

Seat belt tongue

An anti-rattle tongue plate is provided that includes two different materials for being operably connected to the body of the tongue plate. One of the materials is softer than the other to minimize noise when the tongue plate engages against interior components of the vehicle such as during rough ride conditions. One of the materials is made into a distinct component for being operably connected to the tongue plate body. In this manner, the tongue plate herein eliminates at least one of the insert molds needed for prior over molded latch plates, thus providing manufacturing and cost efficiencies thereover.

Anti-rattle tongue plate and method of forming same

Seat belt retractors for spooling seat belts (webbings) include multiple independent torque transmission or absorbing systems. The seatbelt retractor comprises a webbing, a spool, a pinion, a pretensioner, at least one coupler pawl, and a locking mechanism including a lock base and a lock pawl. The at least one coupler pawl is positioned in a cavity in the spool. During a predetermined low acceleration event, the at least one coupler pawl pivots so that a portion of the at least one coupler pawl leaves the cavity and engages the lock base to load the lock base which is then prevented from rotating in a spool extracting direction by the locking pawl. When the pretensioner activates during a predetermined higher acceleration event, the pretensioner rotates the pinion in the webbing retraction direction to rotate the spool in the webbing retraction direction.

Pretensioned retractor

A guide loop assembly for a seat belt has a core body with spaced front and rear flanges and an arcuate bearing surface for the seat belt extending therebetween. An arcuate shell cover is provided and has a concave configuration relative to the arcuate bearing surface. The shell cover extends between the front and rear flanges thereof. The shell cover includes a bushing portion integrally connected by a flexible hinge to the concave core configuration portion. The integral hinge is connected to an impact cover as by threading a flexible portion of the hinge through a hinge portion such as a split pin on the impact cover. In a method assembly, the impact cover and shell cover are hinged together and mounted on the core. After the fastener is inserted through the assembly, the impact cover is pivoted about the hinge to cover a fastener for the assembly.

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.

Simplified height adjuster for D-ring

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.

Pretensioner with integrated gas generator

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.

Seat belt system including an airbag

A seat belt retractor has a spool for seat belt protraction and retraction. An energy absorption mechanism is provided for absorbing energy from the spool during seat belt protraction. The energy absorption mechanism has a first part for a relatively high rate of energy absorption and a second part for a relatively low rate of energy absorption. A shift mechanism for shifting between the first part and the second part is also provided. The shift mechanism is a link movable between a first link position wherein the first part is engaged with the spool and a second link position wherein the second part is engaged with the spool. The link is drivable between the first link position and the second link position by energy from seat belt protraction.

Multilevel load limiting retractor with dual shifting mode

A seat belt retractor assembly has a seat belt retractor for generating a retraction force to rewind a seat belt on a reel. A coupling device selectively couples and decouples the retractor from the reel. A tensioning device generates a tensioning force in the seat belt when in an activated state. The coupling device decouples the retractor from the reel when the tensioning device is activated.

Clutch for tension reducer

A seat belt retractor () comprising: a primary () and secondary () locking mechanism and deactivation mechanism () for mechanically deactivating the second locking mechanism () when the retractor is used by occupants not in a designated class; the retractor including at least two load limiting mechanisms including for example, a torsion bar and variable elongation webbing or a torsion bar and a friction brake (or clutch) configured to be selectively employed depending on the size of the occupant.

Mechanical shifting of multi-load retractor

A seat belt retractor comprising: a first and a second energy absorption mechanism each of which is selectively activatable and respectively configured to generate first and second levels of energy absorption and when activated define an output characteristic of the retractor; a switch mechanism for operatively selecting one or the other energy level and a mode shifter for shifting between the first energy absorption level and the second energy absorption level as a function of the rotation of a spool of the retractor.

A system ( ) comprising a buckle presenter ( ) and/or a tongue presenter ( ) and mechanism to activate and control each presenter. The buckle presenter and tongue presenter ( ) are used to respectively move a seat belt buckle ( ) and a corresponding tongue ( ) from a stowed position to activated positions generally in front of the occupant to make the process of inserting the tongue into the buckle more convenient.

Seat belt buckle and tongue presenter system

A belt tightening device (100/100') for use with a safety device such as a seat belt buckle: a flexible member (12), such as an anchoring length of seat belt webbing, operatively connected to the safety device (34); a housing (102) including a first opening (110) through which the flexible member loosely extends; first and second relatively movable clamping members (160, 162) for causing a portion of the flexible member extending from the housing to be drawn into the housing thereby shortening the remaining length of the flexible member causing a safety belt operatively attached to or part of the flexible member to become more tightly disposed about a user thereof.
