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.

A clutch 100 of the present webbing retractor has a gear wheel 116 and spring claws 182, and has peripheral direction load receiving portions 120 at the gear wheel 116, and load from the spring claws 182 is applied along a peripheral direction via the peripheral direction load receiving portions 120. Therefore, compactness and weight reduction of the clutch 100 can be aimed for. Further, the clutch 100 has a ring 176, and the ring 176 integrally has a cover portion 178 holding respective clutch structural members at predetermined assembly positions, and the spring claws 182, and is held integrally with a rotor 124 by elastic forces of the spring claws 182. In this way, the respective clutch structural members can be temporarily held (sub-assembled) integrally.
摘要:
A webbing retractor which allows one-way transmission of rotation from a motor by using a clutch, as well as achieving improved operation of pulling-out and taking-up of the webbing in ordinary use. In the clutch 100 of the present webbing retractor, a clutch main body 114 is not supported by a spool 20, but by a case (a clutch case 101 and a clutch cover 102) with a spindle 133 provided at an accommodating portion 132 of a rotor 124 at one side in an axial direction the spindle 133 being rotatably supported in a round hole 135 of the clutch cover 102 via a rotation support portion 175 of a holder 170, and with the accommodating portion 132 at the other side in the axial direction being rotatably supported by the clutch case 101 via a busing 112. Therefore, in the present webbing retractor, unless the clutch is in a connected state, the spool 20 can rotate independently of the clutch main body 114

摘要:
A webbing take-up device (10, 100) is disclosed, wherein a motor (44) is provided directly below a take-up shaft (20) between a pair of leg plates (16, 18) with a rotary shaft (50) of the motor (44) disposed perpendicularly to the take-up shaft (20), and a clutch (26) is provided at one side of one leg plate (16). Further, a gear (76) of a motor gear portion (46) is removably connected to a worm gear (34) in a clutch gear portion (28), and a mounting stay (84) is detachably attached to a case (30) with screws (86), so that the motor (44) and the motor gear portion (46) can be detached independently of the case (30) while still being assembled together. Still further, a pretensioner mechanism (156) and a sensor mechanism (182) are provided at one end side of a spool (118), and an urging mechanism (136) is disposed at the other end side thereof.

摘要:
A webbing retractor for an elongated, strip-shaped webbing belt used for application to a body of a vehicle occupant riding in a vehicle. The webbing retractor has: a frame in which a pair of leg plates, which are disposed so as to face one another, are connected by a back plate so as to be integral; a spool which is disposed between the pair of leg plates, one end of the webbing belt being anchored to the spool; a driving mechanism which is disposed between the pair of leg plates and has an output shaft and which is for rotating the spool in at least a take-up direction; and a clutch disposed between the pair of leg plates, transmitting rotation of the output shaft to the spool. Because a motor and gears can be disposed between the leg plates of the frame, the webbing retractor can be made compact.
