A belt tensioner tightens a belt strap of a vehicle seat belt whose belt buckle tongue, which is arranged movably on the belt strap, is inserted into a belt buckle. The belt buckle is attached to a retaining cable having a cable guide formed in such a way that one length of a guide path of the retaining cable can be extended in the cable guide to tighten the belt strap.

A restraint system for use in a vehicle may include a seat; a belt system having at least one belt and at least one belt-adjusting mechanism; and at least one buckle. The belt-adjusting mechanism may be disposed at a first side of the seat and the buckle may be disposed at a second side of the seat. An end portion of the belt may be connected to the belt-adjusting mechanism; and the belt system may have a locking member for locking with the buckle. The restraint system may also include a belt pretensioner that includes a force transmission member; and an actuator configured to actuate the force transmission member for tightening the force transmission member and/or the belt. The actuator may be configured to be actuated and/or triggered by an operator.

A seat belt for a vehicle comprises a first tongue coupled to a first webbing, the first webbing configured to cover portions of a shoulder, a chest, and an abdomen of a passenger; a first buckle coupled to the first tongue; a second tongue coupled to a second webbing, the second webbing configured to cover portions of the abdomen of the passenger; a second buckle coupled to the second tongue; and an actuator configured to upwardly pull the first tongue and the first buckle, wherein the first buckle is coupled to the second buckle; and upon a collision of the vehicle, the actuator operates to separate the first buckle from the second buckle, and the first webbing moves upward, restricting a movement of an upper body of the passenger.

An occupant crash protection includes: a seatbelt that restrains a front-seat occupant sitting in a front seat; a retractor that is installed inside a seatback of the front seat and reels in one end side of the seatbelt, inserted inside the seatback, so as to allow the seatbelt to be pulled out; and a rear-seat airbag module that is installed inside the seatback, on a seat rear side relative to the seatbelt, and inflates and deploys an airbag toward the seat rear side of the seatback while inflating a part of the airbag toward a seat front side so as to press the seatbelt toward the seat front side.

A vehicle traveling control apparatus includes an abnormality determining unit and a seat belt controller. The abnormality determining unit determines presence of impaired consciousness of a driver on a condition that the vehicle traveling control apparatus performs, to an own vehicle, automatic driving on a basis of traveling environment information on a traveling environment in which the own vehicle travels and traveling information of the own vehicle. The seat belt controller causes a seat belt of a driver's seat of the own vehicle to be retracted, when the abnormality determining unit determines the presence of the impaired consciousness.
