A motor vehicle comprises a three-point safety belt device to a motor vehicle seat, wherein the safety belt device comprises a belt, a belt magazine, a belt buckle for releasably securing the belt and a deflection member. The deflection member is provided for guiding the belt emerging from the belt magazine and for deflecting the belt and forming a belt portion of the belt, wherein the belt portion is guided over a shoulder and a chest of a secured motor vehicle occupant seated on the motor vehicle seat. The deflection member is designed such that in the state of the motor vehicle occupant secured by the belt, when the belt portion is subjected to an increased tensile loading, the belt portion performs a displacement from a comfort position into an emergency position in the direction of the motor vehicle interior.

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.

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.

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.

Seatbelt assemblies for motor vehicle occupant restraint providing enhanced frontal impact restraint characteristics. Embodiments illustrated a displacement of the intersection positioned between the lap and shoulder belt portions of an active three-point type belt system. In one set of embodiments particularly useful with dual retractor systems, adaptive positioning provisions allow the point of intersection to initially occur at or near the seatbelt latch plate and when a restraint load occurs components release to allow repositioning of the intersection. In other embodiments best implemented in single retractor systems, a turning loop is provided which displaces the webbing slot separating the lap and shoulder belt sections from the buckle latch plate.

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.
