Abstract: A vehicle sensitive retractor control system having reduced sensitivity to Z-axis acceleration experienced during normal driving. The retractor control system incorporates a rolling mass and a locking lever which, in a resting position, are arranged such that the locking lever does not engage a ratchet wheel of a seat belt retractor spool. In response to accelerations in the horizontal plane, the rolling ball mass becomes unseated from its resting position and allows the locking lever to rotate due to the position of its center of gravity relative to its pivot point allowing it to pivot and lock the retractor. In response to Z-axis acceleration, the rolling mass is prevented from contacting the locking lever by a mass restrictor.

Abstract: A seatbelt pretensioning retractor assembly for use in a vehicle is provided. The seatbelt pretensioning retractor assembly includes a housing adapted for being mounted to a frame and having an interior cavity, a pretensioner tube having an arcuate and curved shape, a pretensioner wheel rotatably mounted to the housing and fixedly coupled to a spindle, a pretensioner rod disposed within the tube and a guide plate having a guide portion and a rod guide. The pretensioner rod engages with the pretensioner wheel during pretensioning. In addition, the pretensioner wheel includes a body portion, a pair of flanges radially extending from the body portion and a plurality of vanes with the cavities formed between adjacent two of the plurality of vanes.

Abstract: A seatbelt pretensioning retractor assembly for use in a vehicle is provided. The seatbelt pretensioning retractor assembly includes a housing adapted for being mounted to a frame and having an interior cavity, a pretensioner tube having an arcuate and curved shape, a sprocket rotatably mounted to the housing and fixedly coupled to a spindle, a polymer rod disposed within the tube and a guide plate having a guide portion and a rod guide. The polymer rod exits the tube along a perimeter of the sprocket, and toward an arcuate landing surface of the guide portion. In addition, the rod guide is configured for preventing the polymer rod from trapping before engaging with the sprocket or after pretensioning.

Abstract: A tongue for a motor vehicle seat belt restraint system providing high friction restraining belt webbing transfer through the tongue in an impact condition. The tongue incorporates a deformable element which maintains the webbing away from contact with high friction elements in the normal use of the belt system. In a crash condition in which significant tension loads are applied to the belt webbing, the deformable element yields to provide contact between the belt webbing and a high friction surface which restricts the transfer of the webbing from the shoulder belt portion of the webbing to the let belt portion of the webbing which is normally more highly loaded in an impact condition. Several embodiments of deformable elements are described.

Abstract: A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a one-piece tread head pinion including a ring portion having a plurality of teeth and a pair of flanges on each side of the teeth. The tread head pinion is formed as a single piece and includes a shaft extending from a side and a bearing portion extending from a second side. A bending element mounting portion extends from the bearing portion. The one-piece tread head pinion is attached to a spindle via a torsion bar, and the spindle bears against the bearing portion when the spindle rotates relative to the tread head pinion. The one-piece tread head pinion may include a staking cavity extending into the bearing portion with a staking wall that is deformable toward a digressive bending element inserted into the staking cavity.

Abstract: A seatbelt buckle device includes a housing, a frame, a latching arrangement and a release button. The frame includes a bottom wall and first and second laterally spaced walls. The latching arrangement selectively retains a latch plate within the housing. The release button is movable between a latched position and an unlatched position. A proximal end, a distal end and first and second laterally spaced apart legs of the release button cooperate to define an opening into which a projecting portion distally from the proximal end. At least one shield member laterally extends from the projection portion toward the first and second laterally spaced apart legs. Each shield member includes an outboard side spaced from an adjacent leg of the first and second legs by a gap. Each gap slidingly receives one of the first and second laterally spaced walls of the frame.
