A vehicle occupant restraint system for a seat of a vehicle. The system includes a first arm portion mountable on a first side of the seat, the first arm having an engaging portion; and a second arm portion mountable on a second side of the seat, the second arm having an engaging portion, the engaging portion of the first arm portion being engageable with the engaging portion of the second arm portion to restrain an occupant on the seat. At least one of the first arm portion and the second arm portion is adjustable relative to the seat.

An occupant protection device including a seat belt including a shoulder belt and a lap belt, a locking tongue that is detachably joined to a buckle, that allows the seat belt to pass therethrough, and that is capable of switching between an unlock state in which the seat belt is allowed to move with the locking tongue being between the shoulder belt and the lap belt and a lock state in which movement thereof is restricted, a shoulder-belt puller that is capable of pulling the shoulder belt to apply a tensile force thereto, a side-collision detector that detects a side collision or a precursor thereof, and a control unit that changes a state of the locking tongue into the lock state and causes the shoulder-belt puller to pull the shoulder belt when the side-collision detector detects the side collision that occurs opposite an occupant or the precursor thereof.

A latching mechanism is applied to be mounted on a webbing of a seat belt system. The latching mechanism has a tongue assembly and a slider mounted on the tongue assembly. The slider has a bridge located at a side of the tongue assembly. The webbing passes through a bottom end of the bridge and is inserted through the slider and the tongue assembly. The webbing has a shoulder belt located at a side, which has the bridge, of the latching mechanism. When the slider is located in an unlocked position, the latching mechanism is capable of freely moving along the webbing. A tension of the shoulder belt acts on the bridge for driving the slider to move from the unlocked position to a locked position, such that the webbing is clamped and locked by the slider and the tongue assembly.
