Patent number: 7637536Abstract: A seat belt retractor (40) associated with a seat (10) includes a spool (106) about which seat belt webbing (42) is wound. The spool (106) is supported for rotation in a belt withdrawal direction and in an opposite belt retraction direction. A vehicle sensitive sensor (190) is responsive to at least one sensed vehicle condition for preventing rotation of the spool (106) in the belt withdrawal direction. A first mechanism (206) is responsive to a first condition for disabling the vehicle sensitive sensor (190). A second mechanism (294) is responsive to a second, different condition for preventing rotation of the spool (106) in the belt withdrawal direction. The second condition is a condition of the associated seat (10). In one embodiment, a third mechanism (400) is responsive to the first condition for allowing rotation of the spool (106) in the belt withdrawal direction.Type: GrantFiled: March 20, 2006Date of Patent: December 29, 2009Assignee: TRW Vehicle Safety Systems Inc.Inventors: Neal H.

Patent number: 7083192Abstract: An apparatus (10) includes an inflatable vehicle occupant protection device (12) and a vent opening (44) for directing flow of inflation fluid away from the protection device. A vent member (46) is movable between an open condition enabling flow of inflation fluid through the vent opening and a closed condition at least partially blocking flow of inflation fluid through the vent opening. A tether (50), when tensioned, moves the vent member (46) from the open condition to the closed condition. A latch (48) has a latched condition for maintaining the vent member (46) in the closed condition and an unlatched condition for enabling the vent member to move away from the closed condition. A controller (102) is operative to actuate the latch (48). selectively to the latched condition and the unlatched condition based on at least one sensed occupant condition.Type: GrantFiled: June 23, 2003Date of Patent: August 1, 2006Assignee: TRW Vehicle Safety Systems Inc.Inventors: Kurt F.

Patent number: 6959945Abstract: A vehicle occupant protection apparatus (10c) has an inflatable occupant protection device (12c) and a support member (20c) having a vent opening (44c). A vent member (46c) is associated with the vent opening (44c). A tether (50c) extends between the protection device (12c) and the vent member (46c). The vent member (46c) is initially in a first condition closing the vent opening (44c). The vent member (46c) is moved to a second condition spaced apart from the vent opening (44c) and enabling fluid flow through the vent opening (44c) upon initial inflation of the protection device (12c). The vent member (46c) is moved from the second condition back toward the first condition by tension in the tether (50c) that results from inflation of the protection device (12c) away from the support member (20c) by more than a predetermined distance.Type: GrantFiled: June 28, 2004Date of Patent: November 1, 2005Assignee: TRW Vehicle Safety Systems Inc.Inventors: Kurt F. Fischer, Neal H. Delventhal

Patent number: 6851715Abstract: An apparatus (10) comprises seat belt webbing (24). An elongated member (30) is connected with the seat belt webbing (24). Tension in the seat belt webbing (24) is transmitted to the elongated member (30). An arm (106) is associated with the elongated member (30). The arm (106) receives a force from the elongated member (30) when tension in the seat belt webbing (24) increases. The force acts on the arm (106) through a moment arm creating a torsion force on the arm (106). At least a portion of the arm (106) moves in response to the torsion force. A device (102) is responsive to movement of the at least a portion of the arm (106) due to the torsion force to provide an output signal indicative of the tension in the seat belt webbing (24).Type: GrantFiled: March 12, 2002Date of Patent: February 8, 2005Assignee: TRW Vehicle Safety Systems Inc.Inventors: Scott D. Devereaux, Randall J. Wolyniec, Michael Badyna, Brian P. Malott, Neal H. Delventhal, Bob McFalls

Publication number: 20040232670Abstract: An apparatus (510) includes seat belt webbing (24). An elongated member (520) is connected with the seat belt webbing (24). Tension in the seat belt webbing (24) is transmitted to the elongated member (520). A sensor of the apparatus 510 includes an arm (560) that is associated with the elongated member (520). The elongated member (520) moves at least a portion of the arm (560) in response to a change in tension in the seat belt webbing (24). The sensor also includes a device (558) that is responsive to movement of the arm (560) to provide an output signal indicative of the tension in the seat belt webbing (24). Structure (604) of the apparatus (510) reduces a variable moment acting on the arm as a result of off-axis loading of the seat belt webbing (24).Type: ApplicationFiled: April 7, 2004Publication date: November 25, 2004Applicant: TRW Vehicle Safety Systems Inc.Inventors: Scott D.
