A rotation control apparatus includes an engagement lever configured to restrict a rotation of a pinion gear by engaging with a ratchet wheel and a drive lever driving and rotating the pinion gear in a direction where a seat moves upward by integrally rotating with an operation member in a state where the drive lever engages with the ratchet wheel based on a rotation operation of an operation handle in a first direction. The engagement lever disengages from the ratchet wheel by the rotation of the pinion gear in a case where the seat moves upward. The rotation control apparatus further includes an engagement lever control piece and a drive lever control piece which cause the engagement lever and the drive lever respectively to disengage from the ratchet wheel based on the rotation operation of the operation handle in a second direction.

A seat slide device for a vehicle includes a first rail, which includes a first horizontal wall, a first vertical wall, and a first flange, and a second rail, which includes a second vertical wall and a second flange. A joining was connects the second vertical wall with the second flange. The coupling portion between the first horizontal and vertical walls includes a first ball guide. The basal end portion of the second flange includes a second ball guide. A first ball is arranged between the first and second ball guides. A restricting member that projects on the first horizontal wall functions to reduce a vertical space between the joining wall and the first horizontal wall and is contactable to the joining wall when the second vertical wall is deformed due to a load that is applied to produce pushing force between the first ball and the second rail.

Seat slide device for vehicle

A seat sliding device for a vehicle includes a first rail and a second rail coupled to the first rail to make relative movement with respect to the first rail. A lever is coupled to the second rail to rotate about an axis extending in the widthwise direction, and a lock plate which is fixed to the rear end part of the lever part and arranged between first side wall parts to extend in the widthwise direction astride side wall part through holes and folded wall part through holes. At both edge parts of the lock plate in the widthwise direction, there is formed a latching part which engages with a latched part of the first rail when the lever part rotationally moves in one direction and is released from the latched part when the lever part rotationally moves in the other direction.

Seat sliding device for vehicle

A seat sliding device for a vehicle includes a first rail, which is adapted to be fixed to one of a vehicle floor and a seat and a second rail, which is adapted to be fixed to the other one of the vehicle floor and the seat and coupled to the first rail to make relative movement with respect to the first rail. An urging member is provided with a latch part, which is latched to a second coupling wall part and a latch end part, which is latched to a lock lever. The urging member generates in association with bending deformation an urging force which urges the lock lever in a vertical direction toward a direction in which the lock lever engages with the first rail. The urging member has a coil part wound about a rotating shaft between the latch part and the latch end part.

A vehicle seat sliding apparatus includes: an upper rail configured to freely support a seat thereabove; a lower rail supporting the upper rail in a relatively movable manner; a locking mechanism capable of switching between a lock state where the relative movement of the upper rail with respect to the lower rail is regulated and an unlock state where the relative movement is allowed; and an unlock operation prevention mechanism regulating an unlock operation of the locking mechanism based on a deployment pressure of an airbag which is disposed in a seat cushion.

Vehicle seat sliding apparatus

A seat slide apparatus for a vehicle includes a tower rail, an upper rail, a memory base arranged above a bottom wall portion of the lower rail, a restriction piece holding the memory base so that the memory base is restricted from moving, a memory pin attached to the memory base in a manner that advance and retract of the memory pin relative to the memory base is allowed, the memory pin engages with the lower rail in a protruding state, the memory pin disengages in a retracted state, an interlocking mechanism pushing a lock member and the memory pin in a forward-folded state of a seatback, and a holding member holding the protruding state of the memory pin and allowing the memory base to move.
