Abstract: A retractor for controlling the withdrawal of a belt therefrom operated by the locking engagement of a buckle and buckle tongue. A retractor frame having a spring biased rotatably mounted spool wrappingly receives one end of a belt harness, with the opposite end of the belt harness having fixed thereto either a buckle or a buckle tongue. Attached to a seat is either a buckle or a buckle tongue that receives the corresponding mating part of the buckle tongue combination which is attached to the belt harness. A locking bar is engagable with the ratchet shaped end plates of the spool to prevent further withdrawal of the belt harness. The locking engagement of the buckle and tongue causes movement of the locking bar into contact with the ratchet shaped end plates, which prevents the spool from rotating to allow any further withdrawal of the belt harness.

Abstract: A retractor having means for controlling the withdrawal of a belt therefrom operated by a push button. A retractor frame has a spring biased rotatably mounted spool wrappingly receiving one end of a belt harness with the belt harness having an opposite end with buckle members fixed thereto to receive a buckle tongue. A locking bar is engageable with ratchet shaped end plates of the spool. The locking bar is pivotable into the ratchet shaped end plates to prevent further withdrawal of the belt harness. A manual push button control causes movement of the locking bar away from the ratchet shaped end plates to allow withdrawal of the belt harness until the push button is released and the locking bar pivots into its normal position in contact with the ratchet shaped end plates.

Abstract: A seat integrated seat belt system. A three point seat belt system includes a belt having one end affixed to the seat and an opposite end mounted to a retractor secured to the seat. A seat belt tongue is mounted to the belt intermediate the belt ends and is releasably lockable with a belt buckle on the opposite side of the seat thereby pulling one portion of the belt across the passenger lap and another portion of the belt across the passenger upper torso. The belt extends through a guide located at the top of the seat. A seat tether includes a second belt having one end attached to the seat at the location of the guide and a second end mounted to a second retractor located beneath the seat. The second retractor is operable to limit motion of the seat thereby minimizing the impact of vehicle motion on the first belt securing the passenger to the seat.

Abstract: A seat belt buckle with a pair of buckle tongues. The buckle includes a spring mechanism slidably movable within the buckle housing from a position blocking engagement of a latch when a single tongue is inserted to a position away from the latch when both tongues are inserted allowing the latch to engage the tongues. An indicator is slidably mounted to the buckle push botton in the buckle cover and includes a lower end contacting the latch. The indicator is movable from a position flush with the buckle push botton when the latch is not engaged with the tongues to an upraised position over the button when the latch moves up and engages the tongues. The tongues have mating portions, but are separable.

Abstract: A seat belt buckle has a plastic outer body of a color and style suitable for the intended environment, with a formed steel inner frame having horizontally-spaced upturned sides having two parallel pairs of in-turned flanges serving as crush inhibitors, release slide guides, and tongue receiver guides. An upturned frame front flange cooperates with the sides and flanges as a wrack resistor and tongue retainer. The body front has a trough-shaped entrance to admit a latchable tongue, one margin of the entrance being provided by the sloped front of an end-release operating slide. A removable slide front button is curved to assist finding for release. A pivoting latching member with a latching pawl thereon is spring-urged into position latching the pawl with the tongue, and released by a cam on the slide, with a shallow ramp for ease of intentional release. A tongue ejector holds the pawl in unlatched position when the tongue is out of the buckle.

Abstract: A seat belt system which incorporates a seat belt assembly including a buckle and mounting brackets, a tongue, a retractor, and webbed belting is disclosed in combination with a member for collecting a predetermined amount of slack in the system in lieu of its collection by the retractor. The member for collecting slack having a relatively retracted first position and a relatively extended second position and including a feature to urge the member to the first position. The application of an external force of sufficient magnitude causes the member to move to the second position, but when the force is withdrawn, the member returns to the first position. When used in a system which also incorporates a retractor assembly, the seat buckle assembly overcomes the tendency of the system to cinch down on the user.
