A seat belt to increase a force for restraining a passenger's lower body in a sitting state of a relaxation mode while satisfying existing laws in a normal sitting state and to a movement control method thereof includes an anchor unit provided on a lower portion of a first side surface of a seat and configured for allowing webbing of the seat belt to be locked thereto and an anchor moving apparatus configured to move the anchor unit forwards and backwards thereof, and to a movement control method thereof.

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 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.

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 system for improving safety of an occupant by a vehicle seat belt, which can provide adaptive protection for an occupant in different seat positions and different sitting postures is provided. A method for improving safety of an occupant by a vehicle seat belt is also provided, along with a a computer-readable medium. The a system for improving safety of an occupant by a vehicle seat belt includes an in-vehicle observation system, an active seat belt system, and an integrated safety domain control unit. The integrated safety domain control unit formulates a vehicle seat belt protection strategy based on received data from the in-vehicle observation system, and a slack state of an active retractor and a positional state of an active lift buckle in the active seat belt system, to implement selective tightening or loosening of the active retractor and/or selective lifting or lowering of the active lift buckle.

A vehicle includes a vehicle body having a pillar. The vehicle includes a track supported by the pillar. The vehicle includes a bar supported by the track. The bar is slidable relative to the track from a raised position to a lowered position. The vehicle includes a seatbelt webbing extending over the bar. The vehicle includes a piston supported by the pillar. The piston includes a piston rod connected to the bar and a piston cylinder supported by the pillar. The piston rod and the piston cylinder define a volume filled with a resilient material.

Guidance to a vehicle occupant is directed to manual adjustment of a height of a D-ring mechanism of a safety belt. First data of the occupant is collected which is indicative of a target height for the D-ring mechanism. Second data is collected indicative of a current height of the D-ring mechanism. The target height and the current height are compared to generate an adjustment amount whenever their difference is greater than a predetermined threshold. Visual guidance is presented to the occupant on an HMI display panel wherein the visual guidance describes taking an particular action to achieve the manual height adjustment of the D-ring mechanism. A further visual instruction is presented to the occupant on the HMI display panel wherein the visual instruction identifies the adjustment amount.

A safety belt presentation system includes a safety belt presentation track extending from a first position to a second position spaced from the first position, a latch that includes a tongue disposed between a first side of the latch and second side of the latch and a first coupling portion, and a driving mechanism that includes a second coupling portion configured to releasably couple the first coupling portion of the latch. The driving mechanism is configured to control the latch to move from the first position to the second position along the safety belt presentation track when the first and second coupling portions are coupled.
