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.

A system includes an in-cabin sensor, a seatbelt routing zone module, and a seatbelt routing classification module. The in-cabin sensor is operable to generate an image of an occupant in a vehicle seat. The seatbelt routing zone module is configured to generate a seatbelt routing zone based on at least one of a size of the occupant in the image and a shape of the occupant. The seatbelt routing classification module is configured to determine whether a seatbelt is routed properly around the occupant based on whether the seatbelt is at least partially within the seatbelt routing zone.

Provided is a vehicle seat in which a transverse guide of a belt guide is located on a seat front side and an upper side with respect to two fixation portions of the belt guide and in which two side guides each include a linear portion extending linearly from the transverse guide toward a back frame.
