摘要： A spool 20 and a locking base 40 are connected through a torsion bar 70. A stop gear 82 and a positioning member 86 are engaged through threads with the male thread 42c of a locking base 40 so as to be separated from each other a predetermined distance. The locking base 40 and the torsion bar 70 are mounted to the spool 20 while the distance of separation between the stop gear 82 and the positioning member 86 is accurately set to a specified distance. When the tension of webbing increases due to the movement of a vehicle occupant in a vehicle collision and provides the torsion bar 70 with EA rotation while twisting the torsion bar 70, the stop gear 82 advances toward the positioning member 86 and comes into contact therewith.

摘要： Shock absorbing seat belt height adjusters for use with vehicle occupant restraint systems, and associated systems and methods. In one embodiment, a shock absorbing height adjuster includes an adjustable D-ring that is operably coupled to an anchor point on a vehicle frame near a seat occupant's shoulder. The height adjuster can include an anti-cinch feature that enables the D-ring to elastically respond to tension loads in a shoulder web portion of the occupant restraint through at least an initial portion of D-ring movement.

摘要： A seatbelt webbing includes an auxetic portion elongated along an axis. The auxetic portion includes a plurality of segments rotatably connected to each other at hinges. The hinges are spaced along the axis and are transverse to the axis. The auxetic portion includes a plurality of strands. Each strand is embedded in at least two of the hinges. When tensile force above a predetermined level is applied to the auxetic portion by a vehicle occupant, e.g., the chest of the vehicle occupant, the auxetic portion both stretches along the axis and widens transverse to the axis, i.e., has a negative Poisson ratio.

摘要： A seat belt device for a vehicle seat, having a seat belt, the belt tongue of which in an engaged state is releasably connected to a seat-side belt buckle. The belt buckle is guided via at least one wire rope through a sleeve-like deflection element, which defines the course of the wire rope between its connection point on the seat side and its connection point on the belt buckle side. The sleeve-like deflection element has a predetermined deformation point, at which the deflection element is deformed in the event of a head-on collision, more specifically with the belt buckle being displaced from its use position into a crash position in which the tilt or twist moments acting on the belt buckle are reduced.

摘要： A buckle device includes: a buckle body to which a tongue portion mounted on a three-point seat belt is to be connected; a connecting member that is flexible and that has a first longitudinal end portion connected to the buckle body; and a force limiter mechanism including a take-up shaft around which a second longitudinal end portion of the connecting member is wound, the take-up shaft being supported below the buckle body in a vertical direction of a vehicle so as to be rotatable relative to a vehicle seat or a vehicle body, and an energy absorbing member that is deformed by rotation of the take-up shaft.

摘要： A vehicle occupant protection device includes: a seat belt device having a selectable force limiter that is configured to switch a force limiter load from a high load to a low load; an airbag device that deploys an airbag in front of the occupant; a movement direction detector that detects a direction in which a head region of the occupant will move relative to the vehicle at the time of frontal collision; an initial position detector that detects a position of the head region prior to the movement; and a control unit that makes a determination whether or not the head region will move outside of an area of protection by the airbag based on detection results of the movement direction detector and the initial position detector and, in a case in which the determination is affirmative, maintains the high load of the force limiter load.

摘要： A vehicle seat includes a seat cushion, a pair of left and right side frames, a webbing including a lap webbing portion, and a buckle. The vehicle seat also includes a first link bracket that is connected to the webbing, and a second link bracket that is connected to the buckle and that is tilted toward one side together with the first link bracket by pulling on the lap webbing portion. The vehicle seat also includes a restriction bar that links the first link bracket and the second link bracket together in a seat width direction, that is moved toward a seat upper side by tilting of the first link bracket and the second link bracket toward the one side, and that restricts movement of an occupant seated on the seat cushion toward a seat front side.

摘要： A seatbelt retractor for a seat belt device in a vehicle. The retractor includes a frame and a spool configured to be fixed to one end of a seat belt webbing so that the webbing may be wound around the spool. The spool is rotatably mounted at both ends to the frame and configured to rotate in a webbing extraction direction and a webbing retraction direction. The retractor includes a staged torsion bar positioned end to end in the spool along an axis of rotation of the spool. The retractor also includes a shift assembly to shift between the stages of the staged torsion bar. The shift assembly includes a shift link locked by a shift collar and a shift ring meshed in a shift plate.
