A webbing take-up device includes a spool, a motor that includes a rotation shaft, and an A-gear, a B-gear, a holder gear, an input gear, a clutch gear, an idle gear, and a spool gear that transmit rotation of the rotation shaft to the spool. The webbing take-up device further includes clutch weights that are moved toward a rotation-radial direction outside by being rotated together with the input gear such that rotation force of the input gear is transmitted to the clutch gear. Moreover, axial centers of rotations of the A-gear, the B-gear, the input gear and the clutch gear, and the idle gear are disposed between an axial center of rotation of the holder gear and an axial center of rotation of the spool gear.

A seat-belt retractor comprising a seat-belt spindle which is rotatably mounted in a housing, an electric motor for driving the seat-belt spindle, and a gear mechanism that transmits the rotational motion from the electric motor to the seat-belt spindle, wherein: the gear mechanism, when deactivated, can be driven as an assembly for driving the seat-belt spindle with a first torque; the seat-belt retractor has a first part, which, when a tensile force exerted by the seat-belt is exceeded, is driven in a rotational motion opposite to that of the rotational direction of the electric motor; and a braking device, which brakes the rotational motion of the first part, thereby actuating a blocking device blocking a second part of the gear mechanism, the blocking device activating the gear mechanism to transmit the rotational motion of the electric motor in a reduction ratio to the seat-belt spindle.

A web retractor may include a frame with spaced-apart first and second side walls and a bottom wall coupling together the side walls, the frame defining an opening through the first side wall, the second side wall or the bottom wall, a spool rotatably mounted to and between the first and second side walls and spaced apart from the opening, a web having one end mounted to the spool, the spool being rotatable to take up and pay out at least some of the web, and a web deflector mounted to at least one of the first side wall, the second sidewall and the bottom wall and positioned between the spool and the opening, the web deflector configured to guide the web from the spool out of the web retractor through the opening and to guide the web into the retractor and to the spool through the opening.

An assembly for a vehicle includes a seatbelt buckle, a seatbelt retractor, and webbing retractably extendable from the seatbelt retractor and releasably engageable with the seatbelt buckle. The webbing is extendable from the seatbelt retractor from a fully retracted position toward an extended position. The assembly includes a vibration motor on the seatbelt buckle. The assembly includes a computer having a processor and memory including instructions executable by the processor to activate the vibration motor in response to movement of the webbing from the fully retracted position toward an extended position. The vibration motor provides haptic guidance to an occupant to engage the clip with the seatbelt buckle.

A system includes a pillar and a seatbelt retractor. The system includes a D-ring supported by and vertically movable relative to the pillar. The system includes a webbing extending from the seatbelt retractor and through the D-ring, The system includes an actuator operatively coupled to the D-ring to vertically move the D-ring relative to the pillar. The system includes a computer having a processor and a memory storing instructions executable by the processor to determine that the seatbelt retractor in a nuisance locked state, and in response determining that the seatbelt retractor is in the nuisance locked state, command the actuator to move the D-ring vertically downward relative to the pillar.

A damped web retractor may include a frame, a spool including a spool shaft rotatably mounted to the frame, wherein the spool is configured to couple to one end of a web such that the web wraps around the spool as the spool shaft rotates relative to the frame in a web take up direction and such that the web unwraps from the spool as the spool shaft rotates in a web pay out direction, and a damper operatively coupled to the spool shaft, the damper configured to resist rotation of the spool shaft in at least one rotational direction.

An engagement and disengagement device used in a seat belt retractor includes a first rotating member and a second rotating member configured to be coaxial, and a transmission member disposed between the first and second rotating members. The first rotating member defines an engagement portion on a radial inner surface thereof, and the distance from the engagement portion to an axis of rotation gradually increases in a first direction of rotation. The transmission member can rotate between an engagement position and a non-engagement position relative to the first rotating member.

A vehicle body rear connection structure includes an extension rear transverse that connects a pillar member disposed in a vertical direction of a vehicle body to a transverse member disposed in a width direction of the vehicle body at a rear of the vehicle body, and of which a seat belt mounting portion is formed, and a reinforcement transverse extension which is mounted on a side of the extension rear transverse, and a lower portion of which is connected to a floor panel.
