A reinforced spool assembly has a shaft, a spool member coaxially mounted around the shaft, and two ratchets mounted on two axial ends of a combination of the shaft and the spool member. Each one of two ratchets has a body having an inner surface. The two inner surfaces of the two bodies face each other. In each one of the ratchets, the body has a reinforced supporting structure. The reinforced supporting structure is located between the shaft and the spool member and is offset from the inner surface of the body. A reference plane is defined on and extends along the inner surface of the body, is perpendicular to a central axis of the shaft, and passes through the reinforced supporting structure. Mechanical strength of the reinforced spool assembly is increased by the reinforced supporting structure.

A belt retractor (40) having a belt reel (14), a seat belt (12) which can be wound thereon to form a belt reel, and at least one first assembly, the first assembly being arranged coaxially with the axis of rotation of the belt reel (14) and in series with the belt reel (14). The belt retractor is especially adapted for mounting inside the frame member of a motor vehicle seat.

A restraint system includes a retractor housing; a spool rotatably coupled to the retractor housing and defining an axis of rotation; a torsion bar elongated along the axis of rotation and positioned coaxially in the spool; a cylinder elongated along the axis of rotation, extending coaxially around the torsion bar, and positioned coaxially in the spool; and a cutter fixed to the spool, the cutter including a cutting edge engaging the cylinder.

A webbing take-up device includes a spool on which a webbing worn by an occupant is taken up, and a motor that includes a rotor with a rotation shaft and a motor housing covering part of the rotor, the rotor being urged toward one axial direction side of the rotation shaft with respect to the motor housing. The webbing take-up device further includes a second transmission mechanism that includes an A-gear fixed to the rotation shaft, and a B-gear meshed together with the A-gear and rotated by the A-gear being rotated toward one side together with the rotation shaft such that the spool is rotated. A helix angle of respective outer teeth of the A-gear is set such that an axial direction force toward the one axial direction side of the rotation shaft acts on the A-gear when the rotation shaft is rotated toward the one side.

A webbing take-up device includes a spool on which a webbing worn by an occupant is taken up, and a motor that includes a rotation shaft and a first boss portion disposed coaxially with the rotation shaft. The webbing take-up device further includes an A-gear that is fixed to the rotation shaft, and a B-gear that meshes together with the A-gear and that is rotated by the A-gear being rotated such that the spool is rotated. The webbing take-up device further includes a gear housing that includes a B-gear support portion on which the B-gear is supported, and an engaged hole engaged by the first boss portion so as to have tightening margin therebetween, and to which the motor is fixed in a state in which the first boss portion has engaged with the engaged hole.

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.

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.

There are provided a side panel constituting a vehicle side face at a higher level than a damper attachment portion suspending a rear wheel, a retractor fixed to a cabin-inside face of the side panel, a frame member forming a closed-cross section extending vertically in corporation with the side panel, and a reinforcing member fixed to the side panel. The reinforcing member comprises a retractor attachment portion to attach the retractor, a gusset portion to partition the closed-cross section of a C pillar reinforcement vertically, and a vibration-damping joint portion joined to the side panel via a vibration-damping material. Herein, the reinforcing member is formed integrally by a member which is configured to be continuous over a range of the retractor attachment portion, the gusset portion and the vibration-damping joint portion.

A belt retractor device for a vehicle comprises a first device component (12), a second device component (14) and a detent mechanism (16) including a first detent element (26) and a second detent element (28). The first detent element (26) has at least two stops (58) which are offset from each other in the radial direction and in the axial direction relative to a mounting axis (20). The second detent element (28) includes a detent edge (40) configured to engage in one of the stops (58) of the first detent element (12) and to prevent the first device component (12) and the second device component (14) from moving relative to each other against the mounting direction of the mounting axis (20).

A seatbelt pretensioner system for use in a seatbelt retractor assembly having a spindle includes a frame assembly having a frame and an attachment bracket adapted to be interlocked to have an inner space for receiving the spindle, a housing adapted for being mounted to the frame and having an interior cavity, a pretensioner tube having a first tube end in fluid communication with a gas generator and a second tube end in fluid communication with the interior cavity of the housing, a pinion being rotatably mounted in the housing and fixedly coupled to the spindle adapted for taking up seatbelt webbing during pretensioning, and a pretensioner rod disposed inside the pretensioner tube. Further, the pretensioner rod has a proximal end disposed towards the gas generator and a distal end disposed away from the gas generator.
