20090134691 | Cylinder in pretensioner for seat belt retractor and pretensioner for seat belt retractor employing the same - Provided is a pretensioner for a seat belt retractor. The pretensioner for a seat belt retractor of a vehicle includes a torsion bar on which a webbing is wound; a gear member connected to the torsion bar; a base member with which the gear member is meshed and through which the torsion bar passes; a cylinder having a movement guide hole formed therein to supply a gas upon rapid deceleration of the vehicle; a piston having a rack formed at a side surface thereof in a longitudinal direction to be meshed with the gear member and moved along the movement guide hole upon supply of a gas, and; a cylindrical sealing operation part integrally formed with a bottom of the piston and projecting therefrom; and a sealing part coupled to an outer periphery of the sealing operation part to seal between the piston and an inner wall of the cylinder, wherein the base member has a hooking means for hooking the piston to a rack. Since the rack of the piston is hooked by the hooking means and assembled thereto, it is possible to form an appropriate gap (or a marginal space) between the sealing part and the straight movement guide hole. | 05-28-2009 |
20090152933 | SEAT BELT TENSION SENSOR ASSEMBLY - Described herein is a seat belt tension sensor assembly that includes an anchor plate adapted to be secured to an object, a housing associated with and movable with respect to the anchor plate, wherein the housing defines a cavity therein, and a sense element disposed in the cavity. The sense element is adapted to produce an output in response to a force placed thereon. The output provided by the sense element is a function of the force placed on the housing by a seat belt up to a predetermined maximum value. The housing does not move until the maximum value is reached, and, after the maximum value is reached, the output of the sense element does not substantially change from the maximum value. | 06-18-2009 |
20100102617 | Method and Belt Tensioning System for Restraining Passengers of a Vehicle Upon Impact with an Obstacle - In a method and apparatus for restraining passengers in a retaining passengers in a vehicle upon impact with an obstacle, a possible accident is initially sensed. Thereafter, at the latest, whenever the vehicle first contacts the obstacle, or whenever vehicle deceleration exceeds a threshold, a force acting in the direction of impact is exerted upon the passenger via a seat belt system. The force is introduced by bilateral tensioning of a lap belt of a seat belt system, from both sides at a force of at least 2000-4500 N. The latter is maintained for a retaining phase of at least 20 ms along a displacement path of the passenger. | 04-29-2010 |
20100141011 | Belt Tensioner for a Seat Belt System - A vehicle seat belt tensioner comprises a traction element that transmits a tensioning force to a seat belt strap. The traction element may be formed for example of a flexible rope or a wire, or a thrust element which can transmit traction and thrust forces. A force limiting unit, which limits the retaining force exerted by the seat belt strap on a passenger has a functional element coupled to the traction or thrust element, which is displaceable by means of a displaceable piston element in the effective direction of the tensioning force. The vehicle belt tensioner according to the invention includes means for the parallel application of tensioning force to both the piston element and the traction or thrust element, concurrently. | 06-10-2010 |

20110068614 | PRETENSIONER - In the present pretensioner, press contact portions are formed further to a side of an open end of a packing housing section than central portions of opposing faces along a depth direction of the packing housing section. Accordingly, when a packing is being fitted into the packing housing section, no great resistance is imparted to a curved face side of the packing from a press contact wall of a housing section body and the opposing face, and the packing is fitted comparatively smoothly therein. Consequently, even when fitting the packing into the packing housing section, a packing main body is largely resilient-deformed, such that a large collapse in a through hole can be prevented, and the sealing ability of the seal due to deformation of the packing main body can be effectively enhanced. | 03-24-2011 |

20120007409 | KNEE BELT RESTRAINT - A three-point seat belt assembly for an occupant sitting in a seat of a motor vehicle is provided. The three-point seat belt assembly can include a seat belt web that has a shoulder harness portion and a knee portion. The shoulder harness portion extends across the occupant's torso and the knee portion extends across the occupant's knees. In addition, a guide member can be included that prevents the knee portion of the seat belt web from sliding up above the occupant's knees and sliding down towards the occupant's shins. A pretensioner can further be included and be attached to the seat belt web. The pretensioner can have a release force of between 5 and 6 kilonewtons which is an improvement over current limits of between 2 and 3 kilonewtons. | 01-12-2012 |
20120025588 | SEAT HARNESS PRETENSIONER - Various embodiments of seat harness pretensioning devices for use in land, air, and sea vehicles are described herein. In one embodiment, a seat unit for use in a military land vehicle or helicopter includes a stroking device that enables the seat to move downwardly in response to sudden movement. The seat unit also includes a seat belt or harness that extends around the occupant in the seat. Sudden movement of the seat in response to an explosion or hard landing causes a tensioning system to automatically pretension the seat harness. | 02-02-2012 |

20120217787 | OCCUPANT RESTRAINT SYSTEM WITH BELT GUIDE ACTUATOR - An occupant restraint system for a vehicle seat has a belt with a shoulder-belt portion extending diagonally across the seat between an upper portion of first side of the seat and a lower portion of a second side of the seat. An upper belt guide is mounted adjacent to the upper first side of the seat and engages the shoulder-belt to allow it to slide along the guide during belt retraction and extension. A safety sensor/control system generates a signal indicating a condition requiring improved occupant restraint in the seat. A guide actuator is activated in response to the safety sensor/control system signal and displaces the upper belt guide in a transverse direction relative to the seat. The displacement of the guide moves the shoulder-belt portion closer to the neck and/or shoulder of the seat occupant to more securely restrain the occupant. | 08-30-2012 |
