  • Patent number: 10086795
    Abstract: Buckle assemblies having load indicating features and associated systems and methods are disclosed herein. In one embodiment, a buckle assembly includes a tang having an opening that receives a web to secure the buckle assembly to a vehicle or a seat structure. The tang also includes an elongate aperture and one or more deformable protrusions along the edge of the aperture. The tang is operably coupled to a buckle frame via a coupling member that extends through the aperture. Upon the application of a sufficient load to the tang, the coupling member deforms the protrusion(s), allowing the tang to move relative to the frame. Movement of the tang relative to the frame can move a colored load indicating region to a position that is visible through a window in a housing of the buckle assembly.

  • Patent number: 9775410
    Abstract: Various embodiments of web adjusters are disclosed herein. In one embodiment, a web adjuster includes a spring-loaded cam member having a bore through which a mounting shaft or pin extends for rotatably or pivotally mounting the cam member to a frame. The cam member can extend along a central axis and include a first engagement feature positioned at a first radial distance from the central axis, and a second engagement feature positioned at a second radial distance from the central axis, larger than the first radial distance. The cam member can be rotated to engage the web to restrict movement of the web. The web adjuster can also include a handle or cover portion and a strap attached to the handle for gripping by a user to adjust the web adjuster.

  • Publication number: 20170215526
    Abstract: Buckle assemblies for personal restraint systems and associated systems and methods are disclosed herein. In one embodiment, a buckle assembly includes a release actuator that can apply a first force and a second force to release a web connector. The release actuator is slidably coupled to a frame that includes a pair of opposing openings. A pawl is pivotally mounted to the frame via the opposing openings and includes a latch portion positioned to releasably engage the web connector. A biasing member is operably positioned between the release actuator and the pawl, and the release actuator is movable to compress the biasing member and exert the first force against the pawl. The release actuator is also movable to contact the pawl to exert the second force against the pawl. The first and second forces urge the pawl to rotate and disengage the latch portion from the web connector.

  • Patent number: 9022483
    Abstract: Self adjusting and/or locking buckle tongue assemblies for use with occupant restraint systems in vehicles are described herein. In one embodiment, a buckle tongue assembly includes a plate having a tongue portion configured to cooperatively engage a corresponding buckle assembly. The buckle tongue assembly of this embodiment can further include first and second web gripping portions carried by the plate. The second web gripping portion is configured to move relative to the first web gripping portion between a first position in which the web gripping portions are spaced apart to permit movement of a web therebetween, and a second position in which the web gripping portions are engaged or interlocked to clamp the web therebetween.

  • Patent number: 8002348
    Abstract: A restraint system for may include a vehicle seat suspended above a floor of a vehicle and a restraint harness coupled to the vehicle seat and configured to restrain an occupant of the seat. The restraint harness may include at least one shoulder web configured to extend over a shoulder of an occupant of the seat and at least one lap web configured to extend over a lap of the occupant. At least one deformable member may be attached to the vehicle seat and configured to deform and dissipate energy when a force is applied thereto by the at least one shoulder web in response to an upward transient force of sufficient magnitude applied to the vehicle seat. A restraint harness pre-tensioning system may be responsive to a signal produced by a vehicle event sensor to tighten the at least one lap web about the occupant.

  • Patent number: 6631926
    Abstract: A clamp for relieving the tension in a seatbelt. An air operated actuator is activated by the passenger at a location remote from the clamp to lock the clamp to the seatbelt. The clamp is slidable on a track with a first endstop and an opposite second endstop. The clamp can be initially secured to the seatbelt at the first endstop. Subsequent movement by the passenger results in the clamp moving along the track. Upon reseating by the passenger, the clamp will be supported at a support position intermediate of the first and second endstops, resulting in increased slack in the shoulder portion of the seatbelt, reduced tension in the shoulder portion, and increased comfort for the passenger.
