A multi-point seat belt safety apparatus and system and device that automatically moves, adjusts, or otherwise corrects itself around one or more webbing deflection points, and utilizes different components, to accommodate seat occupants with different sizes and ages. In particular, when an occupant extends the webbing across their torso towards an anchor point, generally disposed to the near the side of their waist, the webbing first contacts the torso/shoulder of the occupant at a particular distance above the seat, which is reflective of the occupant's height, causing the webbing to automatically move along a length of a deflection element, positioned at, above, or near the shoulder of the seat occupant, to an appropriate deflection point. At such, the webbing is kept at a proper location, away from the neck of the occupant.

A passenger restraint system of a vehicle includes a passenger restraint article with an interface, and a locking device that secures the interface. In some embodiments, the vehicle includes a vertical channel that enables the locking device to travel up and down. The locking device may include a camera that enables the locking device to align with the interface, and once aligned, the locking device secures the interface. In additional or alternative embodiments, the locking device includes two C-bars and a biasing element that urges the locking device into an open position. When the passenger sits or leans against the opened C-bars, the force caused by the interface on the C-bars overcomes the force applied by the biasing element, urging the C-bars into a closed position. The locking device is then secured by engaging a locking bar that pushes against a surface of the C-bars.

An apparatus of adjusting the height of a seat belt, which enables the height of a three-point-type seat belt to be adjusted according to the body shape of a child passenger, securing the safety of a child passenger as well as an adult passenger, includes a sliding rail vertically provided on a side of a seatback; and a slider including a belt ring to hang a shoulder belt, wherein the slider is engaged to the sliding rail and configured to vertically slide along the sliding rail, the belt ring being positioned on a top portion of the seatback in a state in which the slider is positioned on an upper end portion of the sliding rail.

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.

Provided is a pre-tensioner for a seat belt, the pre-tensioner including a housing, a carrier disposed on a first surface of the housing, a fixing member connected to the carrier, a first pulley disposed in a first zone of the first surface of the housing, a second pulley disposed in a second zone of the first surface opposite to the first zone with respect to the carrier, a driving unit having at least a portion coupled to the second pulley, and a belt disposed to mesh with the first pulley, the second pulley, and the carrier.

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.

A system includes a base. The system includes a buckle movable from a retracted position away from the base to an extended position. The system includes an actuator supported by the base and operatively coupled to the buckle to move the buckle to the extended position. The system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the actuator to move the buckle to the extended position in response to determining that tension of a seatbelt webbing is above a predetermined threshold and that a vehicle impact has not been detected.

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.

An apparatus for tensioning an occupant restraint harness coupled to an occupant seat mountable in a motor vehicle, wherein the occupant restraint harness includes first and second lap webs securable about an occupant of the seat, may include a web tensioning device configured to be attached to a rear side of the occupant seat, the web tensioning device having an actuated state and an unactuated state, and a mechanical movement converter configured to be attached to the rear side of the occupant seat and having an input operatively coupled to the web tensioning device, a first output coupled to the first lap web and a second output coupled to the second lap web, the mechanical movement converter responsive to a transition of the web tensioning device from the unactuated state to the actuated state to simultaneously apply tension to the first and second lap webs.
