  • Publication number: 20100207421
    Abstract: A stowable vehicle seat having improved operability and safety at the time of seat stowage are provided. A seat having a seat cushion back includes a foot lock mechanism for inhibiting the rotating of the cushion, a reclining lock mechanism for inhibiting the rotating of the seat back, a strap pullable toward any pull direction, and a lock releasing mechanism for keeping/releasing the rotate inhibiting states of the foot lock mechanism and the reclining lock mechanism by the pulling operation of the strap. When the pull direction of the strap is a horizontal direction, the lock releasing mechanism releases the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism, and when the pull direction of the strap is an upward direction, the lock releasing mechanism keeps the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism.

  • Publication number: 20100109412
    Abstract: There are provided a headrest that prevents looseness, abnormal sounds, and noise caused by a frame urging element or elements and regulating with certainty the rotating of the headrest in a condition where vibrations occur, and a vehicle seat provided with the headrest. A headrest that tilts from a head support state in which the headrest is raised to a storage state includes a pillar mounted in the upper part of a seat back, a headrest frame rotatably engaged with the pillar, a headrest frame urging element or elements for urging the headrest frame to one side, and a locking element or elements that hinder the rotating of the headrest frame and the pillar. The headrest frame urging element or elements includes a shaft disposed on a member constituting the locking element or elements, and a damper and a spring that are disposed on the shaft.

  • Publication number: 20100078972
    Abstract: There are provided a headrest that can be tilted from a head support state to a storage state by an operation at a position separate from the headrest, and an associated vehicle seat. The headrest includes a pillar mounted on the upper part of the seat back; a headrest frame turnably engaged with the pillar; a spring that urges the headrest frame to one side; a locking element or elements that hinder turning the headrest frame with respect to the pillar; a remote control section provided at a position separate from the headrest; and an inner cable one end part of which is connected to the locking element and the other end part of which is attached to the remote control section. The locking element or elements release by pulling the inner cable by the operation of the remote control section.

  • Publication number: 20100072803
    Abstract: Provided are a versatile and thin headrest, and seat for same, that can be operated smoothly by reducing an operation load at the time when the headrest is tilted from a head support state to a storage state, and is capable of preventing noise caused by the headrest. The headrest includes a pillar having a transverse shaft part and mounted to the upper part of the seat back, a headrest frame rotatably engaged with the transverse shaft part of the pillar, a headrest urging element that urges the headrest frame to one side, a locking element that hinders turning the headrest frame and pillar, a ratchet lever operating the locking element and sliding in the transverse direction, and a ratchet lever urging element, that urges the ratchet lever in the direction at a predetermined angle to the ratchet lever sliding in the transverse direction.

  • Publication number: 20100001562
    Abstract: A vehicle seat is provided with an active headrest, in which the thickness of the vehicle seat can be further decreased. A vehicle seat includes a transmission assembly for transmitting a load received by a pressure receiving part to the headrest side, and has a mechanism for moving the headrest when a rear end collision occurs. The transmission means is configured so as to have a lower link that is movably installed in the lower part of the seat back frame of the vehicle seat and is connected to the pressure receiving part; an upper link that is disposed in the upper part of the seat back frame and is movably connected with the headrest; and a connecting link that connects the lower link and the upper link to each other and is operated in association with the operation of the lower link. The connecting link has a bent part bent along the lengthwise direction in the direction such as to separate from the backrest surface of the seat back.
