  • Patent number: 7273228
    Abstract: A curtain airbag device and a guide unit allow for quick deployment of a curtain airbag by smoothly guiding a link strap that connects a curtain airbag and a guide element into the space between a side edge of a pillar garnish and a vehicle member at the early stage of the deployment of the curtain airbag. When an inflator is activated, a curtain airbag is deployed downward along the cabin-side of a pillar garnish. During the deployment, the rear portion of the curtain airbag is guided by a guide rod via a link strap. The link strap starts moving downward along the guide rod when the curtain airbag begins to be deployed. At this moment the link strap is guided into the space between the pillar garnish and a weather strip by a guide member.

  • Patent number: 6267442
    Abstract: A vehicle seat has a tether anchor disposed on a rear surface of a seatback to which a hook on an upper end of a child's seat is engaged for fixing of an upper portion of the child's seat. The vehicle seat has a seatback frame to which the tether anchor is fixed. The tether anchor is covered with a cover formed with a notch along a track of the hook in a locking operation so that a substantial part of the tether anchor is covered with the cover except a portion of the tether anchor on which the hook is locked. This will improve external appearance of the vehicle seat and avoid deterioration of loading ability of the vehicle seat and comfortability of an occupant in the vehicle.

  • Patent number: 5305177
    Abstract: A charging device includes a charging member contactable to a member to be charged. A bias source includes an AC source and a DC source and is effective to apply a bias voltage to the charging member. The bias voltage is provided by a superposing a constant current controlled AC voltage and a constant voltage controlled DC voltage. When a DC voltage is applied between the charging member and the member to be charged, the following equation is satisfied..vertline.(applied voltage V)-(charge voltage V.sub.D of the member to be charged).vertline.=.vertline.(charge starting voltage V.sub.TH).vertline..The charge starting voltage is a DC voltage at a level which the member to be charged starts charging when only a DC voltage is applied between the member to be charged and the charging member. When the above relationship is used in the AC voltage application, the charge voltage V.sub.D oscillates in the charge region with a center of DC voltage V.sub.DC.

  • Patent number: 5263897
    Abstract: A fluid suction nozzle and a fluid-treating apparatus are used in the cleaning of air inside a local space. The suction nozzle has a suction passage and plural annular discharge passages surrounding the suction passage. The nozzle is connected with an air cleaner, etc. The air inside a local space is to be drawn in through the suction passage. At the same time, a larger amount of air is to be discharged from the discharge passages. The velocity at which fluid will flow from the outer discharge passage is smaller than that at which fluid from the same source will flow from the inner discharge passage.
