摘要： A pretensioner having a pipe containing a plurality of balls which are applied with lubrication coating. A clearance for passage of the balls at a distal end of the pipe is determined by the inner diameter of the pipe, the root circle diameter of the external teeth of the ring gear, and the position of a spool coupled to a pinion. The space for allowing the balls to pass is defined by the inner surface of a straight portion of the pipe and contact portions of the external teeth of the ring gear with the balls. The clearance is set so that the width of the space is smaller than the diameter of the balls.

摘要： A belt pretensioner in a vehicle, comprising a piston-cylinder device with a cylinder chamber containing an explosive charge. The piston has a piston rod, which projects out of the cylinder on the side of the piston opposite to the cylinder chamber with the explosive charge, and is joined to a cable, which drives, via a drum and a planetary gear set, a belt reel mechanism in the winding-up direction when the explosive charge is detonated. The cylinder chamber has an evacuation opening, which communicates with a spill valve, which is controlled by an electronic control unit in response to a sensor, which senses the weight of the occupant.

摘要： To reduce the cost of a seat belt retractor having a function of taking up a seat belt by power a motor. A spool is fitted in a base frame such that a torsion bar functions as a shaft of the spool. Two gear-clutch casings are disposed on the left and right sides of the spool via a pretensioner and a locking mechanism, respectively, wherein two motors are disposed to the gear-clutch casings, respectively. The two motors achieve respective functions which are different from each other and rotate at respective constant speeds. Unlike a case that one motor is used and the rotation speed of the motor is controlled, a speed controller and a noise filter for the motor are not required, thereby reducing the cost of the entire device.

摘要： The helmet restraint system of the invention secures the helmet of a driver or passenger occupant of a vehicle, such as a race car, to the structural chassis, body, or frame of the vehicle, independent of the shoulder harness or seatbelt. The system provides a head restraint system which reduces the potentially injurious forces to the neck and head during a high-deceleration event, particularly a frontal collision. The helmet restraint belt system comprises a restraint belt assembly which spans between an anchor point on the vehicle chassis/body and a belt receiving latch mounted to the driver's helmet. The belt is preferably retractable and pre-tensioned by means of a collision or inertially-lockable belt tensioner. The helmet restraint system allows the driver to have unrestricted head movement during normal driving, but restrains the helmet and head during the impact of a collision by locking the belt against further extension. The driver's helmet is attached to the restraint belt by means of a quick-release latch which may be released by the seated driver or a person standing outside the vehicle. Embodiments are disclosed for several different alternative helmet and vehicle mountings of the restraint system, including dual belt, asymmetric restraint systems, and tensioners having internal brake mechanisms that are adjustable to provide tension, either linear or progressive within a preselected range.

摘要： In the seat belt pretensioner device according to the present invention, because the buckle is pulled by urging an intermediate point of the cable, it is possible to pull the seat belt and buckle by a required stroke with a relatively small stroke of the power actuator, and this contributes to a compact design of the device. Because the buckle can be pulled via a fixed point of a cable guide, the buckle and, hence, seat belt can be pulled in a stable manner, and a high level of reliability can be achieved. For instance when the power actuator comprises a piston rod that is pushed out by high pressure gas, because a high pressure gas can be produced with a relatively small device, the size and weight of the device can be minimized. By using a cushioning strucgture for gradually absorbing kinetic energy toward the terminal end of the motion of the power actuator, an inadvertent unlatching of the buckle owing to an impulsive movement of the buckle can be avoided, and an excessive reaction force is prevented from being transmitted to the pretensioner device. This reduces the need for a high mechanical strength, and contributes to compact design. Also, impulsive noises at the terminal end of the operation of the device can be minimized and the device can operate in a quite manner.

摘要： A belt retractor for a seatbelt comprising a retractor pawl which blocks the seatbelt from being pulled out of the belt retractor in the event of an accident, and having a tightening device which tightens the seatbelt in a hazardous situation, the tightening device includes a tightening pawl which, in a blocking position, blocks the belt retractor in the belt uncoiling direction and, in a release position, leaves the belt retractor unaffected. The tightening pawl is assigned a sensor which monitors the position of the tightening pawl and transmits a signal indicating the position of the tightening pawl to a control device of the tightening device.

摘要： A new and useful belt-tensioning device for an occupant restraint is provided, designed to tension a belt (102) about an occupant at the onset of a vehicle collision, and to provide a measure of controlled force dissipation as the occupant loads the belt during the collision. In a preferred form, a tensioning member (122) moves in one direction (124) to tighten a belt about a vehicle occupant at the onset of a collision, and a braking device (130a, 130b) is configured to apply a controlled braking force to movement of the tensioning member in the opposite direction after the tensioning member has tightened the belt about the vehicle occupant. An array of braking members (130a, 130b) applies different levels of braking force to movement of the tensioning member in the opposite direction, thereby providing controlled braking force to movement of the tensioning member in the opposite direction.

摘要： A seat belt retractor with a ball type pretensioner including a pipe in which the balls are retained. A front end portion of the pipe is securely retained so that reliable operation of the pretensioner is provided. The pipe does includes a cut-out that does not extend to the front-most end of a pipe. A guide block is fitted in the front-most end of the pipe. The pipe and the guide block are fixed to the plate together by a fastener. The portion where the guide block is fitted to the pipe can provide high rigidity and is thus hardly deformed in every directions. The fastener may be hardened or the material for the fastener may be selected to obtain sufficient strength.

摘要： An automotive seat safety mechanism includes a seat back and a webbing arranged between the seat back and a vehicle roof. A retractor urges the webbing in a winding direction while simultaneously permitting the webbing to be drawn out in an unwinding direction when in a normal state and prevents the webbing from being drawn out when acceleration of the vehicle becomes greater than a predetermined value. A bypassing mechanism is arranged above the seat back. A pretensioner is included in the retractor. The retractor is arranged above and rearward from the seat back. The webbing extends between an upper position of the seat back and the retractor bypassing the bypassing mechanism. The webbing is disengaged from the bypassing mechanism when forward acceleration becomes greater than a predetermined value. The pretensioner is activated to quickly draw in the webbing in response to the forward acceleration.
