  • Seatbelt device
    Patent number: 9079563
    Abstract: A seatbelt retractor includes a rotation transfer mechanism configured to transfer rotation of an adjustment gear to a sensor housing to swing the sensor housing in the front-back direction of a vehicle. The turning axis of the adjustment gear and the swing axis of the sensor housing intersect each other at a predetermined angle with the swing axis of the sensor housing arranged in a horizontal direction with respect to the left-right direction of the vehicle. An inertial element support surface of the sensor housing is kept horizontal by swing motion of the sensor housing in the front-back direction of the vehicle, even if a seat back is tilted in the front-back direction of the vehicle.

  • Middle side airbag confined between arm-rest and seat
    Patent number: 8985625
    Abstract: An airbag arrangement includes a middle side airbag confined between an arm-rest and a seat. The middle side airbag protects a driver of a vehicle and a passenger from the collision between the driver and the passenger upon vehicle collision. A cushion inflated from a back part of a driver seat is firmly fixed between the driver seat and an arm-rest to restrict the movement of occupants. The middle side airbag includes vertical sewed lines to vertically form a partition, or includes inclined sewed lines to inflate the middle side airbag toward at an expected collision position between the driver and the passenger. An inflator is provided on a lateral surface of a back part of the driver seat. As soon as air is injected into the middle side airbag, the middle side airbag is inflated while forming contact parts confined in the space between an arm-rest and a seat.
