Seat reclining apparatus for vehicle

A seat slide apparatus for a vehicle includes first and second lower rails, first and second upper rails, first and second lock levers, first and second biasing members, first and second support brackets fixed to the first and second upper rails and including first and second support portions, an operation handle including first and second power transmission portions pressing the first and second lock levers so as to release the restriction of the movement of the upper rails relative to the lower rails against a biasing force of the biasing members, and a release lever rotatably connected to the first upper rail and rotating in association with a forward folding of a seat back of the seat to release the restriction of the movement of the upper rails relative to the lower rails by directly pressing the first power transmission portion.

A vehicle seat device includes a first arm connected to a first frame forming a framework of a seat cushion, a second arm fixed to a second frame forming a framework of the seatback, a recliner sandwiched therebetween, a drive source providing a rotation in opposing directions therebetween, the first arm rotationally connected to the first frame, a locking mechanism equipped on the first arm and the first frame restricting rotation therebetween when the first arm is rotated to a first rotational end with respect to the first frame, and a control unit driving and controlling the drive source to adjust the inclination angle of the seatback relative to the seat cushion to a predetermined angle range when the locking mechanism is disengaged and the first arm is rotated to a second rotational end with respect to the first frame.

A seat slide apparatus for a vehicle includes a first rail, a second rail slidably movable relative to the first rail, a lock member restricting a movement of the second rail relative to the first rail, a memory member movably supported within an inner void between the first rail and the second rail and prevented from moving, a first holding member holding the memory member so that the memory member is movable along with the second rail, a second holding member holding the memory member so as to maintain the engagement between the memory member and the first rail, a support bracket fixed to the second rail in the inner void and supporting one end portion of the second holding member, and a rail-side engagement portion arranged at the second rail, engaged with a holding-member-side engagement portion, and preventing the second holding member from being loosened from the second rail.

A seat slide apparatus for a vehicle includes a first rail, a second rail, a lock member, a memory member, a first holding member holding the memory member to move integrally with the second rail in a state where a restriction of the relative movement between the first rail and the second rail is released on a basis of an operation handle, and a second holding member holding the memory member so that the engagement of the memory member with the first rail is maintained in a state where the restriction of the relative movement is released in association with a forward folding operation of a seat back. The first holding member integrally includes a body portion and a memory member holding portion so as to sandwich the memory member in a state where the body portion engages with the front end portion of the memory member.

A seat slide apparatus for a vehicle includes a first rail, a second rail slidably movable relative to the first rail, a lock member restricting a movement of the second rail relative to the first rail, a memory member movably supported within an inner void between the first rail and the second rail and prevented from moving, a holding member fixed to the second rail, holding the memory member so that the memory member is movable along with the second rail, and holding the memory member so as to maintain the engagement between the memory member and the first rail, a first stopper member positioned at one side of the memory member, and a second stopper member positioned at the other side of the memory member and preventing the second rail from moving in a condition where the memory member is sandwiched between the first and second stopper members.

In a vehicle seat sliding apparatus of the type wherein rotating an operating lever causes a lock lever to allow an upper rail to slide along a lower rail, the operating member is supported by a supporting bracket fixed to the upper rail to rotate about a fulcrum which is in the form of a plate of the bracket. The operating lever is provided with a slit into which a spring is fitted for being urged. The bracket also holds the spring. To avoid an engagement between the plate and the slit when the operating lever passes during an assembly of the apparatus, the plate is configured to incline relative to the slit.
