Patent number: 7882920Abstract: A braking force application control is performed when a change in a driver's posture takes place while a brake pedal is turned on when a vehicle is stopped. As a consequence, in a case in which the driver's posture changes such as when the driver turns to a rear seat side to get something without intending to release depression of the brake pedal, creep of the vehicle that the driver does not intend to happen can be inhibited. Furthermore, the vehicle stop retention is only performed when a travelling direction is a forward direction or a seatbelt is worn. As a result, performance of the vehicle stop retention can be inhibited when it is considered that the driver intentionally desires to let the vehicle creep.Type: GrantFiled: November 5, 2008Date of Patent: February 8, 2011Assignees: Advics Co., Ltd., Aisin AW Co., Ltd., Aisin Seiki Kabushiki KaishaInventors: Chihiro Nitta, Kazuhide Adachi, Hideaki Morita, Manabu Matsuda, Kazushi Konno, Shoko Yokoyama

Patent number: 7641237Abstract: The seatbelt device includes: a current wound position detection unit; a driving state detection unit that detects a driving state of the vehicle to transmit a driving state detection signal; a driving state change determination unit that determines a driving state change status based on the driving state detection signal from the driving state detection unit to transmit a driving state change signal; a target wound position setting unit that sets a target wound position of the belt reel based on the current wound position detection signal and the driving state change signal; and a motor control unit that controls a current to be supplied to the motor so as to maintain a state in which the current wound position of the belt reel is equal to the target wound position in accordance with the driving state change signal.Type: GrantFiled: February 5, 2008Date of Patent: January 5, 2010Assignee: Honda Motor Co., Ltd.Inventor: Shotaro Odate

Patent number: 7643920Abstract: A seat-belt pretensioner arrangement comprises a pretensioner (7) and a control system (3-6) to control the tension applied to a seat-belt by the pretensioner (7). The control system (3-6) controls the pretensioner (7) in response to at least the rate of change of steering angle (??). A first processor (4) provides an output indicating a desired level of force to be applied to the seat-belt determined from the steering angle and the velocity of the vehicle. A second processor (5) provides a corresponding output indicative of a desired force level, determined from the rate of change of steering angle (??) and the velocity of the vehicle (vx). A selector (6) selects the highest of the two force levels, and provides an appropriate signal to the pretensioner (7).Type: GrantFiled: October 5, 2007Date of Patent: January 5, 2010Assignee: Autoliv Development ABInventor: Christophe Gillet

Patent number: 7631720Abstract: A seat belt retractor includes a seat belt winding device for winding up a seat belt by actuation of a motor and a control unit that repeats a process of stopping the actuation of the motor on an overload of the motor and restarting actuation of the motor after lapse of a predetermined time period. The control unit includes a detection module for detecting an occupant getting on or off a vehicle and a determination module that, using criteria, determines whether or not actuation of the motor is to be restarted. The criteria when the occupant enters the vehicle is different from when the occupant exits the vehicle. The criteria are provided so that the determination module is more likely to determine that the actuation of the motor is not to be restarted when the occupant enters the vehicle as compared to when the occupant exits the vehicle.Type: GrantFiled: March 21, 2008Date of Patent: December 15, 2009Assignee: Takata CorporationInventors: Masato Takao, Koji Tanaka, Daisuke Murakami

Patent number: 7628349Abstract: An inertia sensitive actuator especially adapted for use with a dual spool retractor for a motor vehicle seat belt system, The dual spool retractor includes shoulder belt and lap belt spool assemblies engaging with the shoulder belt and lap belt portions of the seat belt webbing, The dual spool retractor incorporates an inertia sensitive actuator having an excitation mass which is coupled with both of the retractor spool assemblies via linkages,Type: GrantFiled: March 6, 2007Date of Patent: December 8, 2009Assignee: Autoliv ASP, Inc.Inventors: Gunter K. Clute, Jennifer Grove

Publication number: 20090299577Abstract: An external seatbelt usage indication system and method indicates whether or not the driver and passengers of a motor vehicle are wearing a seatbelt. It provides an indication of non-usage on the exterior of the motor vehicle using existing external lights on the vehicle so that it cannot be defeated by removal of the external indicator or bulbs associated with it. Upon activation of the vehicle ignition, occupant sensors and seatbelt usage sensors are used to determine a non-usage condition, upon which external lights of the vehicle are intermittently activated until the non-usage condition ceases.Type: ApplicationFiled: June 2, 2008Publication date: December 3, 2009Inventor: Istvan Demant

Patent number: 7624833Abstract: A seat-belt pretensioner arrangement includes a pretensioner configured to apply at least two tension levels to a seat-belt and a control system to control the pretensioner. A control system is configured to provide at least one vehicle slip function which is derived from at least one sensed parameter relating to the current or expected dynamic situation of the vehicle. The control system is configured to select the tension level to be applied to the seat-belt by the pretensioner in response to the value of the slip function provided by the control system.Type: GrantFiled: October 8, 2007Date of Patent: December 1, 2009Assignee: Autoliv Development ABInventor: Christophe Gillet

Patent number: 7607508Abstract: A safety restraint system (10) for a vehicle (12) includes a seat belt buckle (60) and a retractor (53) mounted approximately at or below a pelvic level of a vehicle occupant (98). A seat belt (52) extends over a side pelvic portion (97) of vehicle occupant (98) and directly prevents outward lateral displacement of the side pelvic portion (97) during a side collision event.Type: GrantFiled: November 2, 2004Date of Patent: October 27, 2009Assignee: Ford Global Technologies LLCInventors: David Zhao, Leonard A. Shaner, James C. Cheng

Patent number: 7604081Abstract: A vehicle passenger restricting system is provided to restrict passenger movement so that a space between a passenger's head and the ceiling of the vehicle is effectively enlarged when a rollover condition occurs. The vehicle passenger restricting system has a passenger seat, a rollover detector, a seat tilting device and a controller. The rollover detector detects a vehicle rollover condition. The vehicle passenger restricting device restricts passenger movement on the passenger seat. The seat tilting device tilts the seat in a backward direction. The controller activates the seat tilting device to recline the seat backwards when the rollover detector detects the vehicle rollover condition exists. Preferably, the controller also operates the restricting device when it determines that a rollover condition exists.Type: GrantFiled: November 8, 2006Date of Patent: October 20, 2009Assignee: Nissan Motor Co., Ltd.Inventors: Ryuuji Ootani, Chinmoy Pal, Katsushi Saito, Tsuneyuki Watanabe

Patent number: 7597170Abstract: In a method for controlling the operation of a reversible belt retractor to release a belt extraction lock of a restraint belt in a motor vehicle, the lock can be activated by an acceleration sensor. After the belt retractor has been triggered as a consequence of a hazardous situation having been detected and after the hazardous situation has been recognized as being over, the operation of the belt retractor is controlled by a release signal at a release time in order to bring about the release of the belt extraction lock to shift it from a blocking state into a comfort-providing state. The release time is determined by a sensor model algorithm based on a model of the acceleration sensor from at least one variable characterizing the running dynamics.Type: GrantFiled: July 9, 2004Date of Patent: October 6, 2009Assignee: Daimler AGInventors: Ralf Bogenrieder, Walter Eberle, Rainer Justen, Hans Roehm, Guido Villino, Alfred Wagner, Markus Woldrich
