  • Patent number: 10179523
    Abstract: A structure in which two worm wheels are disposed across a worm provides an increase in locking reliability while maintaining stable operation during rotation. At the time of rotation, respective rotating fulcrums set at both end portions in an axial direction of a worm are supported by bearing parts. At the time of locking, a locking fulcrum set at an eccentric position on one end portion in the axial direction of the worm is supported by one bearing part, while on the other end portion in the axial direction, the rotating fulcrum is supported by the other bearing part as is. As a result, the angle of lead of the worm supported by the pair of bearing parts is changed between the time of rotation and the time of locking and becomes smaller at the time of locking than at the time of rotation, whereby an increase in locking reliability can be achieved.

  • Patent number: 8752861
    Abstract: A fixing structure of a rear side airbag device for a vehicle may assure a margin of time for the side airbag to be deployed. In a vehicle rear side airbag device fixing structure, an airbag module is fixed by fastening to a child seat fixing member conforming to ISOFix standards, via a metal plate. The child seat fixing member is fixed to the rear floor of a vehicle body at the downward side of a rear seatback. Therefore, in comparison with a structure in which an airbag module is fixed to a rear wheel housing via a bracket, the airbag module may be disposed to the vehicle width direction inner side. Moreover, the child seat fixing member exhibits a high rigidness with respect to a side collision of the vehicle. Therefore, fixing portions of the airbag module are resistant to being deformed during a side collision of the vehicle.

  • Patent number: 7802490
    Abstract: A multifunction seat control system includes a pulley mechanism in an enclosure, an actuation shaft to attach an external handle, and multiple latch actuation cables. The pulley mechanism includes multiple circumferential slots in which the cables ride, and cable-end entryways through which associated cables ends can be inserted. A lockout device detects a seat-back position to selectively limit the rotational travel of the pulley mechanism. The pulley mechanism is rotationally actuated to a predetermined angle to release a seat-back latch so the seat back can recline or fold forward, and beyond the predetermined angle to release seat-bottom latches so the seat can tumble into a stowage configuration. The control system optionally includes a headrest cable to release a headrest as the seat back is folded forward, and a release strap to actuate the pulley mechanism from behind the seat.
