  • Patent number: 11472367
    Abstract: 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.

  • Publication number: 20220066043
    Abstract: A vehicle with an automatic report function includes a transmitter configured to transmit, to a server apparatus for requesting emergency dispatch, emergency information of the vehicle when a collision of the vehicle is detected or forecasted, a global navigation satellite system (GNSS) receiver configured to receive signal waves and generate a location of the vehicle, a storage configured to store the location generated by the GNSS receiver, and a controller configured to collect information from the vehicle and cause the transmitter to transmit the information as the emergency information when the collision of the vehicle is detected or forecasted. When the collision of the vehicle is detected or forecasted, the controller determines whether the location is acquirable from the GNSS receiver and, when the location is not acquirable, collects a previously generated location and causes the transmitter to transmit the previously generated location to the server apparatus.
