Patent number: 11794688Abstract: 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.Type: GrantFiled: September 14, 2021Date of Patent: October 24, 2023Assignee: AUTOLIV ASP, INC.Inventors: Jon E. Burrow, Matthew R. Schimento, Gunter Clute, Bryan Vanwambeke, Timothy P. Sherrow, Jr.

Patent number: 10625709Abstract: A seat belt retractor for use with a seat belt webbing includes a spindle, a tread head part, a torsion bar, a stop nut and an energy management element. The spindle is configured for winding the seat belt webbing around the spindle. The tread head part is configured for having a locked condition or a free condition. The torsion bar is engaged with the spindle and the tread head part and configured to deflect torsionally by allowing relative rotation between the spindle and the tread head part when the tread head part is in the locked condition. The stop nut is operatively coupled with the tread head part and the spindle and configured to move in axial direction. Furthermore, the energy management element placed between the stop nut and the tread head part is configured to be deformed by the axial movement of the stop nut.Type: GrantFiled: September 17, 2018Date of Patent: April 21, 2020Assignee: AUTOLIV ASP, INC.Inventors: Christopher D.

Patent number: 10575597Abstract: 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.Type: GrantFiled: November 8, 2017Date of Patent: March 3, 2020Assignee: AUTOLIV ASP, INC.Inventors: Jonathon Boughner, Jon E.
