In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

A seatbelt height adjuster includes a track elongated along an axis and including a plurality of holes spaced from each other along the axis, a slider slideably coupled to the track, a D-ring supported by the slider, a pin supported by the slider and releasably engageable with one respective hole, and a pyrotechnic actuator supported by the slider and engaged with the pin.

In the present invention, a seatbelt device is provided with: a seat state determination unit that determines the state of a seat; a movable support section that supports a seatbelt within a range of possible movement on a seat back; a movement mechanism that, with a motor, moves the movable support section within the range of possible movement; and a motor control unit that controls the motor in accordance with the usage state of the seat determined by the seat state determination unit. Due to this configuration, the position of the seatbelt is made optimal for an occupant, and the comfort of the occupant is thus improved.

A vehicle occupant restraint system for a seat of a vehicle. The system includes a first arm portion mountable on a first side of the seat, the first arm having an engaging portion; and a second arm portion mountable on a second side of the seat, the second arm having an engaging portion, the engaging portion of the first arm portion being engageable with the engaging portion of the second arm portion to restrain an occupant on the seat. At least one of the first arm portion and the second arm portion is adjustable relative to the seat.

In a lift-up buckle device, a worm wheel is engaged with a screw drive. When a worm is rotated in a forward direction and causes the screw drive to move downward, the worm moves the worm wheel downward. On the other hand, when the worm is rotated in a reverse direction and causes the screw drive to move upward, the worm moves the worm wheel upward. Consequently, the worm wheel may be stably engaged with the screw drive, and the worm wheel and worm may be stably mated.

A child carrier restraint that allows the upper ends of the shoulder straps to be adjustably positioned to properly secure children having varying torso lengths within the child carrier. The child restraint includes a traditional five point belt harness and pair of shoulder belt location adjusters, which allows the shoulder strap to be selectively positioned over and behind the child regardless of the length of the child's torso. The shoulder location adjusters are mounted to the back of the child carrier and includes a strap loop trained about a locking slide and a bottom strap loop anchor. The end of the shoulder strap is sewn directly to the strap loop. The locking slide can be manually disengaged to allow the strap loop to slide freely, thereby selectively positioning the end of the shoulder strap along the back of the child carrier.
