Abstract: The invention relates to a method for catching and taking up as well as a winding machine for continuously winding up threads. In order to catch the thread on a winding spindle, two thread guides form a thread section upstream and downstream of the winding spindle. Preferably, said thread guides are simultaneously displaced in a synchronous manner during the catching process and in such a way that the thread section is guided vertically over the winding spindle. Preferably, the thread guides are simultaneously and synchronously displaced by coupling the thread guides to each other and displacing the same with the aid of a common drive unit.

Abstract: A seat belt retractor for motor vehicles with a vehicle-sensitive or belt webbing sensitive controllable locking device, or both, for the belt shaft, having a profiled head that acts as a support for a displaceably mounted locking member that locks the belt shaft in the housing, and a two-stage force limiting device having two force limiting elements that are switchable between a high level and a low level of force limitation via an interposed coupling (19, 20) that is controlled by means of a control device having a countergear which determines an amount of belt webbing that is extended from the belt shaft.

Abstract: In a webbing winder, when a webbing belt is wound around a spool, a V gear is rotated in a winding direction together with a W pawl, a friction spring, and a contact member, thereby generating a frictional force between the contact member and a sensor holder. As a consequence, the friction spring and the contact member are located at a restriction position, so that the friction spring engages with an engaging surface of the W pawl. Therefore, even if the spool and the V gear are rapidly and slightly rotated in a withdrawal direction in reaction when the webbing belt is completely wound by the spool, the W pawl cannot mesh with a ratchet gear formed at the sensor holder due to the restriction of oscillation of the W pawl, thus preventing any end lock.

Abstract: A feed mechanism includes a feed slide movable between a retracted position and an advanced position. The feed slide is configured to feed a product strip during a feed stroke as the feed slide is moved from the retracted position to the advanced position and the feed slide is movable with respect to the product strip during a return stroke as the feed slide is moved from the advanced position to the retracted position. The feed mechanism also includes feed fingers pivotally coupled to the feed slide at corresponding attachment points. The feed fingers are movable between an engaged position and a released position, wherein the feed fingers are configured to contact the product strip in the engaged position and the feed fingers are configured to be positioned away from the product strip in the released position. The feed fingers are moved to the released position prior to the feed slide moving along the return stroke.

Abstract: This seatbelt apparatus of a vehicle is provided with: a seatbelt; a belt reel on which the seatbelt is wound; a motor that drives a rotation of the belt reel; a controller that controls a driving amount of the motor; a winding position detection device that detects a winding position of the belt reel. The controller performs a first control mode in which a substantially constant electricity is supplied to the motor, and a second control mode in which the electricity supplied to the motor is controlled based on a predetermined rule; and sets an initial value for the second control mode based on changes in the winding position detected by the winding position detection device, while changing from the first control mode to the second control mode.

Abstract: A combination of belt retractor and belt pre-tensioner in which the pre-tensioning device is coupled to the belt shaft by means of the vehicle-sensitive or belt strap sensitive locking system of the belt retractor, is characterized in that a lever (16) entrained by the drive wheel (10) on its rotation in the pre-tensioning direction is mounted pivotally on the housing and on its pivoting movement effected by the rotation of the drive wheel (10) its free end (18) comes into engagement with the control disc (12) and in so doing, over part of its pivoting movement, drives the control disc (12) for its relative rotation relatively to the belt shaft and after the lever (16) has passed through its pivoting path serving to drive the control disc (12) it is released from the control disc (12) and the drive wheel (10).

Abstract: In a webbing take-up device 10, a worm gear 34, which is connected to a motor 44, engages with a gear wheel 32, and when the worm gear 34 rotates, driving force is transmitted via the gear wheel 32 and a clutch 26, whereby a take-up shaft 20 is rotated in a take-up direction. Helix angles of teeth of the worm gear 34 and the gear wheel 32 are set so that thrust force generated at this time along the axial direction of the gear wheel 32 faces a leg plate 16 fixed side of a case 30. Accordingly, because the thrust force acts on the leg plate 16 fixed side of the case 30, i.e., on a frame 12, there is no need to provide the case 30 or a cover clutch 31 with high strength and rigidity.

A pretensioner is operatively connected to the spindle for rotating the spindle to tighten the seatbelt. The pretensioner includes pretensioner balls. The pretensioner is configured to drive the pretensioner balls toward a ball collection area adjacent to the weakened portion. The weakened portion is deformed by the pretensioner balls to increase the size of the ball collection area.

Abstract: In a motorized retractor, due to an ECU and a driver switching a speed of rotation of an output shaft of a motor to a first speed or a second speed, a transfer path of rotational force from the motor to a spool is switched to a first driving force transferring section (a path through a meshing clutch and a slip mechanism) or a second driving force transferring section (a path through an overload mechanism and a centrifugal clutch). Accordingly, there is no need for a complex switching mechanism including a solenoid which is employed in conventional motorized retractors. A device can thereby be made more compact.

Abstract: A seatbelt retractor reduces the temporary weight during seatbelt withdrawal to increase an occupant's comfort. When a seatbelt is not being worn by an occupant (off), projections of an internal gear are placed in a circumferential center between adjacent projections by the spring force of springs. When a spool rotates in the belt withdrawing direction, the internal gear also rotates in the belt withdrawing direction. This arrangement disables a reduction mechanism's power transmission to cut off the direct connection between the spool and electric motor connected to a sun gear to reduce the temporary weight during withdrawal of the seatbelt. When the internal gear rotates at a predetermined angle, the projections come into contact with the projections to thereby stop the rotation of the internal gear. This enables the power transmission of the reduction mechanism, whereby the spool and electric motor are brought into direct connection via the reduction mechanism.

Abstract: A webbing winding device includes a spool, a pair of leg plates, a torsion shaft, a first locking mechanism, a second locking mechanism, and a control mechanism. A webbing belt is wound onto the spool. The two leg plates oppose one another in an axial direction of the spool. The torsion shaft is provided passing through the spool and deforms when a torque is applied to the spool. The first locking mechanism, at the side of one of the leg plates, restricts rotation of the spool in an unwinding direction. The second locking mechanism, at the side of the other of the leg plates, switches from a lock-release state to a locking state, and restricts rotation of the torsion shaft in the unwinding direction. The control mechanism is provided passing through the spool and causes the second locking mechanism to switch into the locking state.
