The relates to a sensor for activating a vehicle-sensitive locking mechanism of a belt retractor, comprising an inertia body, a bearing supporting the inertia body, a release element which can be moved out of an idle position by movement of the inertia body so as to activate the vehicle occupant restraint system, wherein the inertia body can be pivoted about a stationary point of rotation.

A seat belt device includes a webbing, a locking tongue, and a guide. The webbing includes a lap belt and a shoulder belt. The locking tongue is configured to undergo a change from a free state, in which the webbing is capable of passing between a side of the lap belt and a side of the shoulder belt, to a lock state, in which the webbing is not capable of passing between the side of the lap belt and the side of the shoulder belt, in accordance with a collision or a warning of the collision of a vehicle. The guide is configured to, in accordance with the collision or the warning of the collision of the vehicle, displace a location on the shoulder belt that is adjacent to the locking tongue in a direction away from the occupant before the change to the lock state is completed.

A locking apparatus used for controlling a movable chain, strip or strap-shaped object (71) comprising a support frame; a roll shaft (6) with a friction surface or a sprocket pitch slot (64), the roll shaft (6) being fixedly connected to a support rod (66), and one end of the support rod (66) being pivotally connected onto the support frame; a pawl (62) disposed above the roll shaft (6) and capable of rotating around one end; and a pressurization body (3) opposite to the roll shaft (6) along a transverse direction, thereby forming a roll gap between the roll shaft (6) and the pressurization body (3). The roll shaft (6) can freely rotate when the roll shaft (6) is in a middle state. When the roll shaft (6) is forced to downwards pivot until a ratchet disposed on a contact base (65) engages with a ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6), the object (71) can be locked. When the roll shaft (6) is forced upwards pivot until the ratchet (6302) of the roll shaft (6) abuts against the pawl (62), the roll shaft (6) can still rotate; when the object (71) changes the direction to downwards move, the pawl (62) engages with the ratchet (6302) of the roll shaft (6) to prevent the rotation of the roll shaft (6) and loses the engagement with the ratchet (6302) of the roll shaft (6) as the roll shaft (6) downwards pivots.

The guide is configured to displace a location on the shoulder belt that is adjacent to the locking tongue in a direction away from the occupant in response to the change from the free state to the lock state.

A seat belt device includes a webbing and a tongue. The webbing includes a lap belt and a shoulder belt. At least a portion of the lap belt is configured to be disposed to extend in a vehicle-width direction along a front of an abdomen of an occupant. At least a portion of the shoulder belt is configured to be disposed obliquely along a front of a chest of the occupant. The tongue is provided between the lap belt and the shoulder belt of the webbing and is configured to be coupled to a vehicle body when the tongue is to be mounted. The tongue rotates in accordance with a collision or a warning of the collision of a vehicle in a direction in which the shoulder belt is twisted with respect to the vehicle body.
