  • Patent number: 11840123
    Abstract: There is provided a vehicular seat capable of using an air supply fan having a relatively small capacity so that a thickness of the air supply fan does not become one of factors in determining a thickness of a seat in realizing the reduction of the thickness of the seat. A vehicular seat includes: an air supply fan; an air supply chamber which forms a passage for air supplied from the air supply fan; and a urethane pad which sandwiches the air supply chamber and has a plurality of portions in each of which a hole through which air supplied from the air supply chamber passes is formed. The air supply chamber is formed so as to cover in a planar surface shape a region of the urethane pad including the plurality of portions in each of which the hole is formed.

  • Patent number: 10857918
    Abstract: Provided is a seat-cover fitting structure capable of preventing a seat cover from accidentally separating from a seat main body. In a seat-cover fitting structure 1, a resin clip 41 that is fitted to an end member 10 attached to the lower end of a hanging cotton-cloth member of a seat cover and a metal clip 50 that is fitted to the exterior of the resin clip 41 engage each other with gaps X1, X2, and X3 formed therebetween. In a state where the metal clip 50 is stuck to, by magnetic force, a main-body-side member that is embedded in the seat main body, the resin clip 41 moves with respect to the metal clip 50 within the ranges of the gaps X1, X2, and X3.

  • Patent number: 7309108
    Abstract: A headrest device of a vertically movable type including a headrest body, a stay element and a lock mechanism provided on a seat back of a seat. The lock mechanism includes a lock plate movably disposed therein and a biasing means for normally biasing said lock plate in a locking direction. The stay element is slidably connected with the lock mechanism so as to be vertically movable and has a non-linearly profiled surface region defined in a surface portion thereof with which said lock plate is biased by said biasing means to frictional contact. Such formation of non-linearly profiled surface region is effective in preventing a friction noise from being generated between the lock plate and the stay element.

  • Patent number: 6988768
    Abstract: A vehicle seat apparatus in which a seat is rotated around a rotational shaft to the rear of a vehicle in such a manner that a bottom surface of a seat cushion is made to face the inside of a passenger compartment so that the seat can be stowed in a recessed portion. The rotational shaft extends in a transverse direction along a front edge of the recessed portion to be fixed to a vehicle body at ends thereof. A seat cushion and a seat back of the seat are both divided into at least two in a widthwise direction. Respective seats so divided are rotatably supported on the rotational shaft individually.

  • Patent number: 6935691
    Abstract: Vehicle seat with seat cushion tip-up structure and lock mechanism for slide rail comprising upper and lower rails, wherein the upper rail fixed to the seat is locked and unlocked to the lower rail through the lock mechanism. An unlocking lever provided to the seat cushion is operatively connected via a first connecting link with a first arm element, wherein the first connecting link and first arm element are disposed at the seat cushion. The first arm element is connected with a second arm element disposed outwardly of the seat cushion, the second arm element being operatively connected via a second connecting link with the lock mechanism, wherein the second connecting link is disposed outwardly of the seat cushion. Operating the unlocking lever actuates the lock mechanism to unlock and lock the seat from and to the lower rail, irrespective of whether the seat cushion is tipped up or not.
