  • Patent number: 10040376
    Abstract: A seat frame for a vehicle seat includes a seat cushion frame that forms a frame for a seating portion of the vehicle seat, and a height adjustment mechanism that is coupled to the seat cushion frame and a rail mechanism of the vehicle seat. The height adjustment mechanism adjusts the height of the seat cushion frame. The height adjustment mechanism includes a sector gear that rotates based on a height adjustment operation, a link that moves the height of the seat cushion frame up and down based on the rotation of the sector gear, and a restriction member that abuts against the sector gear, thereby restricting the movement of the sector gear. At least one of portions of the sector gear and the restriction member that abut against each other has a tapered shape.

  • Patent number: 9216667
    Abstract: In a vehicle seat, a positional deviation of a height device for moving a seat main body up and down is suppressed. The vehicle seat includes a cushion frame serving as a frame of a seating portion; the height device for moving the cushion frame up and down; and a side cover that covers the cushion frame and the height device from outside in a seat width direction. An operation lever is positioned in a state of being engaged with a positioning member contained in an outer side surface of the side cover, and an engagement protrusion of the operation lever moves in an engagement hole of the positioning member and abuts on a first stepped portion and a second stepped portion provided around the engagement hole when the operation lever rotates.

  • Patent number: 9162594
    Abstract: Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.
