  • Patent number: 11691592
    Abstract: A CPU of an ECU is configured to compute an estimated acceleration that is estimated to be applied to a vehicle and a remaining time that is taken from present time to acceleration occurrence time at which the estimated acceleration occurs from a road surface condition detected by a road surface condition detection unit and a vehicle status detected by a vehicle speed determination unit and a steering angle velocity determination unit. The CPU is configured to, when the remaining time becomes shorter than or equal to a predetermined value, drive a retractor motor. The webbing is retracted before an occupant moves with an acceleration that is applied to the vehicle, so the occupant is held in a normal seated position. The retractor motor is driven when the time that is taken from present time to acceleration occurrence time becomes shorter than or equal to the predetermined value.

  • Patent number: 11407379
    Abstract: A vehicle occupant restraint system is configured to, when a vehicle speed is higher than or equal to a vehicle speed threshold, a steering angle velocity is higher than or equal to a steering angle velocity threshold set for each vehicle speed, and an estimated lateral acceleration is higher than or equal to an acceleration threshold, drive a retractor motor. The steering angle velocity threshold is as a condition to drive the retractor motor. Therefore, by setting an appropriate steering angle velocity threshold according to an amount of movement of an occupant with inertia in a vehicle width direction, the vehicle occupant restraint system is able to take up a webbing when the occupant is estimated to move with inertia by a relatively large amount in the vehicle width direction. The amount of movement with inertia varies for each vehicle speed even at the same steering angle velocity.

  • Patent number: 10583430
    Abstract: An ion exchange membrane having a structure that an ion exchange resin is filled in spaces of a porous base film, the porous base film has a structure that at least two porous olefin resin layers are laminated with a bonding strength of 100 gf/cm or more to less than 700 gf/cm and a Gurley air permeance of 500 sec/100 ml or less in terms of a 100 ?m thick film. In this ion exchange membrane, base film has high air permeability though it has a multi-layer structure that a plurality of porous resin films are bonded together, and therefore a rise in electric resistance caused by the lamination of the base sheets is effectively suppressed.

  • Patent number: 10525931
    Abstract: A serrated portion is formed on an outer peripheral portion of a lock base body of a lock base of a webbing take-up device. Furthermore, a flange portion is formed on the outer peripheral portion of the lock base body. The flange portion is disposed on a vehicle front side with respect to the serrated portion. Triangular grooves of the serrated portion are closed by the flange portion. When the lock base becomes displaced in a vehicle rearward direction and the flange portion comes into abutting contact with a leg plate of a frame, further displacement of the lock base in the vehicle rearward direction is blocked. Due to this, engagement between the serrated portion and ratchet teeth of a ratchet hole in the leg plate can be maintained.
