Title: Vehicle seat belt device
Inventor: YAMAMOTO KAZUTO
IPC: B60R22/48
Filed: 2020-02-06
Abstract: To effectively suppress the occurrence of the submarine effect during a forward-movement collision, including for occupants in a comfortable state, relating to vehicle seatbelt devices.SOLUTION: A control unit 24 moves a buckle 14 to the ascending position by a lift-up mechanism unit 20 when a forward movement collision is predicted in a state where the reclining angle is equal to or larger than a predetermined angle. After that, when a vehicle collision is detected, a pretensioner mechanism unit 22 is operated. By moving the buckle 14 to the ascending position by the lift-up mechanism portion 20, the tension of a lap belt 12A is weakened. By operating the pretensioner mechanism 22 in this state, the buckle 14 and the lap belt 12A can be largely moved to the front side of the seat. Therefore, even in the comfort state, the lap belt 12A can be moved to the position corresponding to a lower part of pelvis of an occupant P, to be easily pulled down to a lower side of the seat. Thereby, the occurrence of the submarine effect can be suppressed.SELECTED DRAWING: Figure 1
