Abstract: In a webbing take-up device, an open portion is formed in the other side, in a direction about a rotational axis of a switch pawl, of a sensor holder. In a state where an engagement piece is positioned on the outside of the open portion, the switch pawl is rotated about a shaft to cause the engagement piece to enter in a window portion, so, a distal end of the engagement piece, bent in a hook shape, faces to a regulation wall in an axial direction of the shaft. It is not necessary to elastically deform the engagement piece when bringing the regulation wall and the engagement piece into facing. Therefore, the engagement allowance in the engagement piece with the regulation wall can be enlarged and the distal end of the engagement piece can be prevented from crossing over the regulation wall and moving toward the shaft side.

Abstract: A seat belt retractor that functions to cancel both a function of a vehicle sensor and a function of a webbing sensor on a predetermined condition with a simple structure and a small number of components. When a seat belt is fully retracted, a cam follower of a first lever comes into contact with a second cam portion of a cam plate. An actuator pressing portion of the first lever presses an actuator of a vehicle sensor to a non-operation position. The function of the vehicle sensor is thereby cancelled. Further, when an engaging claw of a second lever separates from a ratchet tooth of a ring gear, the ring gear is allowed to rotate in a seat belt withdrawing direction. Therefore, the function of the webbing sensor is cancelled.

Abstract: An extension rib extends from a pressing portion in the take-up direction of an ALR cam and is formed to be able to abut with an ALR pawl. Accordingly, when the ALR cam excessively rotates in the pull-out direction with respect to a set position in a maximal pulled-out state, the ALR pawl abuts the extension rib. Accordingly, it is possible to suppress a state in which the ALR pawl climbs over the pressing portion and engages with a V-gear. Namely, even if a rotation variation of the ALR cam becomes large by setting a speed reduction ratio of speed reduction mechanism to a small value, it is possible to absorb such variation by the extension rib. Thus, it is possible to absorb rotation variation of the ALR cam while improving accuracy of switching timing from the ELR (or ALR) state to the ALR (or ELR) state.

Abstract: When an axis of rotation 9a2 of a spool rotates in the seatbelt retracting direction, a lock gear 13 rotates clockwise which is the same direction as the spool, and an eccentric gear 16 rotates counterclockwise. A cam 20 of the eccentric gear 16 comes into contact with a lever 36 of the control lever 35 to cause the control lever 35 to rotate counterclockwise to take an operating position. A pressed pin 42b of a lever 42 comes into contact with a lever 37, so that levers 42, 43 rotate counterclockwise. A holding portion 42c of the lever 42 opposes a flywheel 14. Accordingly, since the holding portion 42c presses a held portion 14d when the entire amount of a seatbelt 4 is retracted, a rocking movement of the flywheel 14 is prevented and hence end locking is prevented.

Additionally, a locking lever mounted on the control disc is provided for the cutoff of a vehicle sensor, and by way of a switching process in its cutoff position, the locking lever cuts off the vehicle sensor and secures the inertial mass in a disabling position, the disabling position being different than the blocking position.

Abstract: A restriction rotating body is provided at a carrier plate, on the opposite side of a sun gear to a planet gear. When an internal-toothed gear is displaced together with a sensor gear in the rotation radial direction thereof, the internal-toothed gear presses a shaft portion of the restriction rotating body, and further, a gear portion of the restriction rotating body presses the sun gear. Due thereto, the amount of relative displacement of the internal-toothed gear with respect to the sun gear can accordingly be reduced. Moreover, since the restriction rotating body does not mesh with the internal-toothed gear, the restriction rotating body can be easily assembled after assembly of the planet gear. The planet gear can accordingly be easily assembled prior to assembly of the restriction rotating body.

Abstract: A seat belt apparatus for a vehicle including: a belt reel; a emergency locking retractor which performs a mechanical locking of the belt reel so as not to rotate in a direction of unwinding a webbing when an unstable behavior of the vehicle is detected by a vehicle condition detection device, and then automatically release the locking if the belt reel rotates in a direction of winding the webbing greater than or equal to a predetermined amount; and a locking continuity determination device which determines whether or not the locking continues after the emergency locking retractor performs the locking based on the vehicle condition and variation of the rotational position of the belt reel, wherein a control device makes a driving motor rotate so as to release the locking if the locking continuity determination device determines the locking continues for greater than or equal to a predetermined amount of time.

Abstract: To obtain a webbing take-up device that can not only transmit to a take-up shaft only rotation from a motor by a clutch but is also simple and compact. A clutch of this webbing take-up device has a simply configuration where sliders 144 of a clutch body portion 114 are caused by frictional force to be retained in a case, whereby the sliders 144 and lock bars 154 are caused to relatively move and the lock bars 154 are caused by this relative movement to move to positions where they engage with or disengage from a ratchet 134. Consequently, the overall configuration of a clutch 100 can be made significantly compact (thinned) in comparison to a configuration that causes a pawl to move using an inertial disk that is large and has weight as in a conventional clutch. Thus, the overall configuration of a webbing take-up device 10 can be made compact.

Abstract: An inertial (mass) body is relatively rotatably provided on a V gear. Further, a ring is provided at the outer peripheral side of the V gear so as to be rotatable and displacable in the rotational radial direction of the V gear. When the V gear is suddenly rotated with a spool, the mass relatively pivots to the side opposite to the side of the pull out direction, and displaces to the outside in the rotational radial direction of the V gear. By doing so, an inner peripheral portion of the ring contacts with an outer peripheral portion of the V gear, and the ring rotates with the V gear. Due to this a pressing portion provided at an outer peripheral portion of the ring displaces an interlocking pawl, meshing the interlocking pawl with ratchet teeth on an outer peripheral portion of the V gear.

A portion of the periphery of the ratchet wheel has a toothing for engaging the reduction gear mechanism. A further portion of the periphery of the ratchet wheel has a switching contour that rests against a contact pin of an electric switch. The switching contour has a profile that effects the connection or disconnection of the switching device for the torque rod.

Abstract: 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.

Abstract: In a seat belt apparatus, a first projecting portion and a second projecting portion which are capable of being brought into abutment with each other so that a switch lever is shifted from a switch OFF position to a switch ON position are provided on a side of a drive gear and a side of a first gear, respectively.

Abstract: A vehicle sensitive retractor control system having reduced sensitivity to Z-axis acceleration experienced during normal driving. The retractor control system incorporates a rolling mass and a locking lever which, in a resting position, are arranged such that the locking lever does not engage a ratchet wheel of a seat belt retractor spool. In response to accelerations in the horizontal plane, the rolling ball mass becomes unseated from its resting position and engages the locking lever, causing it to pivot and lock the retractor. In response to Z-axis acceleration, the rolling mass is prevented from contacting the locking lever by a mass restrictor. A soft damping spring is also provided to bias the locking lever against a lever rest. The spring is sized to overcome the inertia of the locking lever and prevent it from “bouncing up” and engaging the ratchet wheel in response to Z-axis accelerations.

Abstract: In a webbing retractor, when a V-gear rotates in a take-up direction at an angular velocity of less than a preset upper limit angular velocity VH and a braking pawl moves toward an engaging position, an anchor claw of the braking pawl meshes with an internal tooth of a braking gear, and the braking gear is connected via the braking pawl to the V-gear so as to rotate integrally in the take-up direction. In this way, a coil portion of a torsion coil spring twists in the take-up direction (diameter contracting direction) via anchor pins. Therefore, an inner diameter of the coil portion contracts, and an inner peripheral surface of the coil portion press-contacts an outer peripheral surface of a braking shaft. End locking is prevented from arising when a spool, which rotates in the take-up direction, stops.

Abstract: A belt retractor having ELR and ALR modes of operation is disclosed. The retractor comprises a sensor pawl movable between a released and a locked position with one or more teeth of a ratchet wheel rotatable with a spool of the retractor; the sensor pawl forming part of both ELR and ALR locking mechanisms. A spring biased first lever is rotatable to a first position and when in the first position urges the sensor pawl toward engagement with the ratchet wheel. The lever is movable to a second position, which permits the sensor pawl to move away from the ratchet wheel teeth thereby preventing the retractor from entering into its ALR mode of operation. The lever, when in its second position, biases the sensor pawl into engagement with a cooperating inertial mass that is part of a vehicle sensitive locking mechanism of the seat belt retractor.

Abstract: A seat belt system includes a retractor and a seat belt. The retractor includes a motor that drives a pressure rod into a seat belt such that the seat belt is nipped between the pressure rod and belt receiving portions. The driving force of the motor that controls the movement of the pressure rod is set based on the situation at the time of a collision. Thus, the load limit to be exerted on the seat belt is set flexibly and widely according to the situation in an emergency. Further, the motor and the pressure piston rod can be activated repeatedly and, therefore, can be reused.

Abstract: A seatbelt device for a vehicle includes a belt reel for winding a belt for restraining a target object, a motor for driving the rotation of the reel, and a control unit. The control unit determines whether the target object to be restrained is a child seat or a vehicle occupant on the basis of a winding position of the belt while no electricity is being supplied to the motor and the winding position of the belt when electricity is being supplied to the motor.

Abstract: A belt retractor for a seat belt includes a belt reel, an eccentric disc connected to the belt reel, a cam disc driven by the eccentric disc, and a blocking pawl. The blocking pawl, in a blocking position, blocks a toothed ratchet wheel, and, in a release position, leaves the toothed ratchet wheel unaffected. The blocking pawl may be switched from the release position into the blocking position and conversely from the blocking position into the release position with the cam disc. For the belt retractor to be independent of tolerances, provision is made for the cam disc to have an engaging cam for engaging the blocking position of the blocking pawl and a disengaging cam for engaging the release position of the blocking pawl.

Abstract: A braking actuator for an ergonomic support is connected thereto by a Bowden cable. The actuator has a housing with pin slots, friction surfaces and a mount for a disk axle. A disk has frictional surfaces, holes with pin load edges, a Bowden cable wire seat that holds the Bowden cable end and an axle that is supported by the mount in the housing. The friction surfaces of the disk and housing engage each other to brake the actuator and the ergonomic support. A lever having pins is disposed on the housing such that the pins extend through the pin slots to engage the holes in the disk. Turning the lever disengages the friction surfaces and rotates the disk, thereby moving the ergonomic support. Releasing the lever engages the frictional surfaces such that movement of the ergonomic support is braked at a selected position.

Abstract: A seat belt retractor having a force limiter mechanism that can be stably operated when a pyrotechnic pretensioner is activated. As a pyrotechnic pretensioner is activated, a ring gear rotates in the counter-clockwise direction. Accordingly, an external tooth holding an end portion of a stopper is moved, whereby the end portion of the stopper becomes free. Therefore, the stopper expands because of its biasing force. Then, a release spring is released from the restriction of the stopper and thus pivots in the clockwise direction because of its biasing force. The release spring collides with a pin of the clutch pawl to press down the pin. Therefore, the clutch pawl is rotated about a clutch pawl pin in the clockwise direction, thereby canceling the mechanical connection between the motor and the spool.

Abstract: A belt retractor for a seat belt includes a belt reel, an eccentric disc connected to the belt reel, a cam disc driven by the eccentric disc, and a blocking pawl. The blocking pawl, in a blocking position, blocks a toothed ratchet wheel, and, in a release position, leaves the toothed ratchet wheel unaffected. The blocking pawl may be switched from the release position into the blocking position and conversely from the blocking position into the release position with the cam disc. For the belt retractor to be independent of tolerances, provision is made for the cam disc to have an engaging cam for engaging the blocking position of the blocking pawl and a disengaging cam for engaging the release position of the blocking pawl.

A switch is provided which is adapted to be actuated by the control disk when a predetermined amount of belt webbing has been drawn off the belt spool and the control disk has been turned into a predetermined position.

Abstract: A webbing take-up device that can prevent unintended and unnecessary switching from an ELR mode to an ALR mode. In a webbing take-up device, a cam protrusion and a tongue portion are provided at a cam member that interlocks with a take-up shaft, and a breaking operational portion and an intermediate holding surface are provided at a disc control member. When a switch is made from the ELR mode to the ALR mode, unwinding and taking-up operations of the webbing are each preformed twice in succession so that the webbing take-up device is switched to the ALR mode, in which an ALR pawl engages with an outer-tooth ratchet wheel of a locking wheel. Accordingly, unless the aformentioned switching is carried out by conscious volition of a vehicle occupant, unintended and unnecessary switching from the ELR mode to the ALR mode does not occur.

An automatic locking mechanism selectively locks the spool against paying out webbing. A switch has a first position for activating the automotive locking mechanism in dependence upon a predetermined amount of webbing being wound off the spool, and a second position for deactivating the automatic locking mechanism in dependence upon a predetermined amount of webbing being wound back onto the spool. A gear connects the spool with the switch mechanism having a first and a second actuator tab on the gear. A pivotally mounted actuator member has an actuator pawl for locking the spool and parts engaging with the first and second tabs to move the switch between the first and second positions. The tabs and the engaging parts are radially oriented in line, one with the other.

Abstract: A seat belt retractor operates in two distinct modes: a first, Emergency Locking Retractor (ELR), mode; and a second, Automatic Locking Retractor (ALR), mode. A toothed ratchet wheel is mounted to rotate with a spool that is biased in a seat belt webbing rewinding direction. A sensor detects an emergency condition of the vehicle. A vehicle acceleration sensor lever responsive to the sensor engages the ratchet wheel in the event of an emergency condition. The vehicle acceleration sensor lever performs two functions: it locks the retractor when the sensor detects accelerations and decelerations greater than a predetermined magnitude and it also prevents rotation of the spool in the seat belt webbing pay-out direction when operating in its second mode. A cam connected to the spool via a step-down gearing arrangement acts as a switch.

A pivotally mounted actuator member has an actuator pawl for locking the spool and parts engaging with the first and second tabs to move the switch between the first and second positions. The tabs and the engaging parts are radially oriented in line, one with the other.
