A seat assembly includes a seat back and a headrest adjustably coupled to the seat back. The headrest defines a first guide passage and a second guide passage, each extending through the headrest. The seat assembly includes a retractor and a belt. The belt extends continuously from a first end to a second end. The first end is engaged with the retractor. The belt has a looped portion from the first guide passage to the second guide passage. The belt extends from the looped portion through the first guide passage to the first end, and extends from the looped portion through the second guide passage to the second end.

Apparatuses comprising a guide plate for safety restraint webbing is described herein. Also, systems comprising a guide plate and shroud for safety belts or restraint webbing are described herein.

An assembly includes a webbing. The assembly includes a first webbing guide receiving the webbing. The assembly includes a second webbing guide receiving the webbing and releasably secured to the first webbing guide. The assembly includes an actuator. The assembly includes a cable secured to the actuator and to the second webbing guide.

A seatbelt latch plate assembly includes a latch plate, a D-ring, and a pivot stop. The D-ring is pivotably connected to the latch plate. The pivot stop is disposed between and rotatably fixes the latch plate to the D-ring. The pivot stop includes a deformable element. The deformable element is deformable at a predetermined pivot torque between the D-ring and the plate.

An assembly includes a base defining a track and a hole. The assembly includes a plate slidably engaged with the track. The assembly includes a pin supported by the plate and movable between a first position engaged with the hole and a second position disengaged with the hole. The assembly includes an actuator designed to move the pin from the first position to the second position. The assembly includes a webbing guide supported by the plate.

A webbing guide for a vehicle seat includes a base defining a length between a first end and a second end and defining a plurality of pairs of corresponding spaced-apart post holes extending through the base between top and bottom surfaces thereof. The webbing guide further includes a guide body coupled with the base and defining a guide channel extending through the guide body in a direction generally normal to the length of the base and normal to the post holes.

A buffer device has a plate, a moveable ring, and an elastic member. The plate has an insertion hole formed through the plate, a connecting portion, and a retaining hole. The connecting portion and the retaining hole are formed on the plate and are located above the insertion hole of the plate. The moveable ring is moveably mounted out of a front side of the plate and has a slot. The slot is formed through the moveable ring. The elastic member is connected with the connecting portion of the plate and the moveable ring. A top section of the elastic member is wound on the connecting portion of the plate. A bottom section of the elastic member is wound on a top section of the moveable ring and passes through the slot of the moveable ring.

A sliding mechanism includes a first part and a second part adapted for sliding translation within the first part. A bracket attached to the first part includes a bracket guide rib structure for constraining a lateral motion of the second part, including a rib defining an unbroken interface surface for the second part. The bracket guide rib structure may include a continuous rib member defining a continuous a continuous planar slider interface surface, a sinusoidal wave pattern, or a trapezoidal wave pattern. The sinusoidal wave pattern and the trapezoidal wave pattern may include a plurality of waves having a same or a different wave frequency.

A seat belt energy management loop to reduce off-axis loading is disclosed. The seat belt energy management loop includes a substantially flat bracket welded to the chassis of a vehicle and including a plurality of openings for mounting a roll hoop and a seat belt retractor to the bracket. An integral loop is formed as an integral part of the bracket and extends from the bracket in substantially perpendicular relation to the bracket. The integral loop includes a seat belt guide segment extending from the bracket, a pair of curved end segments extending from the seat belt guide segment, and a straight segment extending between the pair of curved end segments, together forming a seat belt opening through which a retractable seat belt of the retractor extends.
