  • Patent number: 10906429
    Abstract: A seat slide structure includes a cushion frame, a slide rail including lower and upper rails, a movement mechanism, and a lock mechanism. The movement mechanism slides the cushion frame along a length direction of the slide rail. The lock mechanism includes a lock body engaging with the slide rail, and places or lifts a restriction on movement of the slide rail. The movement mechanism includes a lead screw, a gear part, and a shake absorber. The lead screw is provided in parallel with the slide rail, and is supported by the upper rail. The gear part transmits power from a power source to the lead screw to slide the lead screw and the upper rail along the lower rail. The shake absorber allows the cushion frame and the lead screw to move relative to one another in a moving direction of the upper rail along the lower rail.

  • Patent number: 10518672
    Abstract: A vehicle seat capable of housing a seat main body includes a seat pivot shaft to which the seat main body is connected to be pivotable, and a detachable leg whose upper end is mounted to the seat main body and whose lower end is detachably held onto a leg holding member on a vehicle body floor. When the seat main body moves from a housed state side to a usage state side, a leg guide portion causes a cushion abutting portion to abut a base abutting portion in advance, thereby guiding the detachable leg moving together with the seat main body to pass above a leg movement inhibiting portion which is a portion of a support base.

  • Patent number: 9789793
    Abstract: A vehicle seat compactly stowed in a stowed state while suppressing contact between pivot links. A stowable seat includes an inner link, an outer link, and a guide link coupled to a seat cushion of the seat, the links are pivoted with respect to a vehicle body floor in order to move the seat cushion to a stowed position. The inner link, the outer link, and the guide link are arranged at positions different from each other in the width direction of the seat so that contact between the pivot links is suppressed. Further, the guide link is arranged at a position different from the inner link and the outer link in the front to back direction of the seat so that the seat can be compactly stowed.
