Patent number: 11518340Abstract: In a webbing take-up device, side faces of press-fit holes in a pinion are inclined in directions toward the outside of the press-fit holes on progression toward the right. Press-fit portions of a torsion shaft are press-fit into the press-fit holes from the right such that an interference force between the press-fit portions and the side faces of the press-fit holes increases on progression toward the left. This enables the press-fit portions to be effectively retained in the press-fit holes.Type: GrantFiled: January 29, 2019Date of Patent: December 6, 2022Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Shinichi Okubo, Ryu Nakajima, Masanori Nagamine

Patent number: 9409545Abstract: A belt retractor (10) for a vehicle seat belt includes a frame (12) provided with plural blocking teeth (22), a belt reel (14) which is rotatably supported in the frame (12) and includes a blocking tooth system (24), and a control mechanism by which the belt reel (14) can be moved from a home position in which it can freely rotate in the frame (12) into a blocking position in which its blocking tooth system (24) engages in the blocking teeth (22) of the frame. The control mechanism includes a locking lever (80) adjustable between a release position and a locked position in which it locks rotation of the belt reel (14) relative to the control mechanism so that the belt reel (14) can be moved into the blocking position by a tensile force acting in the webbing.Type: GrantFiled: May 7, 2012Date of Patent: August 9, 2016Assignee: TRW Automotive GmbHInventors: Frederic Michel, Pawel Patyk

Publication number: 20150041075Abstract: Provided is a retractable safety gate and locking mechanism for a retractable safety gate that employs a spline lock and spline geometry for extending and locking the gate in an immovable position, and an air check valve and compression spring as a time delay for retracting the gate.Type: ApplicationFiled: August 7, 2013Publication date: February 12, 2015Inventor: William A. Henderson

Patent number: 8777269Abstract: A self-locking belt retractor with a belt shaft which is mounted rotatably in a frame having a belt-sensitive a blocking device. A disc cam (1) mounted rotatably on the belt shaft, is pretensioned by a spring in the extension direction of the seat belt and on which an inertial mass (5) is mounted pivotably about a pivot axis (S). A projection (11) limits relative movement between the inertial mass (5) and the disc cam (1) is provided on the inertial mass (5) and/or on the disc cam (1).Type: GrantFiled: September 10, 2011Date of Patent: July 15, 2014Assignee: Autoliv Development ABInventors: Uwe Bosse, Volkmar Heine, Klaus Werner Butenop

Patent number: 7641139Abstract: A quick acting clutch, the quick acting clutch comprising: a friction plate; a clutch plate movably mounted to the friction plate about a center of rotation of the friction plate and the clutch plate, the clutch plate being configured to rotate with respect to the friction plate; an actuator arm pivotally mounted to at least one of the friction plate or the clutch plate, the actuator arm being configured to amplify movement of a first end of the actuator arm and rotational movement of the friction plate relative to the clutch plate moves the first end of the actuator arm; and a lock pawl pivotally mounted to the clutch plate for movement between a locking position and an unlocking position, the lock pawl and a second end of the actuator arm each being configured to contact each other and rotational movement of the friction plate with respect to the clutch plate causes movement of the first end to be amplified at the second end such that the second end of the actuator arm and the actuator arm contacts the lockType: GrantFiled: August 14, 2007Date of Patent: January 5, 2010Assignee: Delphi Technologies, Inc.Inventors: Kevin Wei-Loong Ng, James L.

Patent number: 7410113Abstract: A seatbelt retractor is disclosed. The seatbelt retractor has a frame, a spindle, a seatbelt webbing and torsion bar. The frame is attached to a structure of a road vehicle. The spindle is rotatably supported by the frame. The seatbelt webbing is wound about the spindle for retraction there to and protraction there from. The torsion bar is fixedly coupled to the spindle for rotation therewith, the torsion bar has a first torsion portion mechanically coupled or press-fitted into a second torsion portion.Type: GrantFiled: December 9, 2004Date of Patent: August 12, 2008Assignee: Autoliv ASP, Inc.Inventors: Gerald Keller, Lloyd Snyder

Patent number: 7051969Abstract: A belt retractor for a vehicle safety belt comprises a frame and a belt spool (1) which is rotatably mounted in the frame, and at least one locking toothing (2, 3) which is connected with the belt spool. A first locking catch (5) and a second locking catch (6) are provided, which are supported on the frame and can engage into the at least one locking toothing (2, 3). The first locking catch (5) is able to swing about a point of rotation which is arranged such that with the first locking catch (5) guided into the locking toothing (2, 3) a virtual line, which passes through a point of contact between the first locking catch (5) and the locking toothing (2, 3) and stands perpendicularly on a tooth face in the point of contact, runs between the point of rotation and a rotation axis of the belt spool (1).Type: GrantFiled: October 6, 2003Date of Patent: May 30, 2006Assignee: TRW Occupant Restraint Systems GmbH & Co. KGInventors: Alexander Heilig, Martin Prokscha
