Patent number: 10605360Abstract: An electronic transmission range select actuator (ETRSA) includes a primary drive system that operates during normal operation. The ETRSA includes an output shaft that is connected to the system via a lock pin during normal operation. The ETRSA also includes a release mechanism having a secondary motor that operates during a power loss or failure of the system. The secondary motor drives a gear that rotates freely relative to the output shaft. Rotation of the gear results in axial movement of the gear toward the lock pin, which in turn causes disengagement of the lock pin from the output shaft, allowing the output shaft to rotate due to the biasing load of a torsion spring such that the output shaft is returned to the P-range position. Thus, the mechanism is configured to return the output shaft to the P-range during a power loss or failure of the first motor.Type: GrantFiled: February 23, 2017Date of Patent: March 31, 2020Assignee: Robert Bosch GmbHInventor: Raul Nava Gonzalez

Publication number: 20110140503Abstract: The disclosed seat belt retractor may include a spool for retracting a seat belt, a torsion bar, a pre-tensioner, and a locking device. The torsion bar may disposed inside the spool, wherein one side of the torsion bar is connected to the spool, and configured to absorb energy of movement of an occupant while being deformed under torsion. The pre-tensioner may be positioned at one side of the spool and configured to generate a rotating drive force for rotating the spool in a retracting direction in a condition of rapid deceleration of a motor vehicle. The locking device may be capable of locking another side of the spool such that a rotation of the spool in a withdrawal direction is suppressed at both an operating time of the pre-tensioner and a non-operating time of the pre-tensioner.Type: ApplicationFiled: December 15, 2010Publication date: June 16, 2011Inventors: Koji HIRAMATSU, Yasushi Kanamori, Masahiro Shiotani, Miwa Morimoto

Patent number: 7837275Abstract: A multi-mode belt retractor including an interlocked attachment mechanism. The belt retractor and attachment mechanism are physically integrated in a single unit. In one embodiment, the retractor is shifted between modes by the operation by the attachment mechanism such that securing the attachment mechanism to an anchor point shifts the belt retractor into a locked mode. Releasing the attachment mechanism from the anchor point shifts the belt retractor into a free-wheel mode. In one embodiment, only a single user-operable button is provided, thus minimizing the opportunity for improper operation. One embodiment of the attachment mechanism is symmetrical, making it operable by a user's left or right hand.Type: GrantFiled: April 22, 2008Date of Patent: November 23, 2010Assignee: Evenflo Company, Inc.Inventors: Thomas Woellert, Guy Robert Dingman, William Cameron Forbes
