In a seat reclining device, a seatback frame forming a skeleton of a seatback is coupled to a seat cushion frame to be rotatable about a shaft with respect to the seat cushion frame. One end portion of a first sliding bracket is rotatably coupled to a middle portion of the seatback frame by a driving unit. The other end portion of the first sliding bracket extends toward a vehicle body located behind the seatback. A second sliding bracket is mounted on the vehicle body located behind the seatback and extends toward the first sliding bracket in a front and rear longitudinal direction to be connected to the first sliding bracket. The second sliding bracket is configured to guide a sliding movement of the first sliding bracket while the first sliding bracket is being rotated.

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, a first elastically deforming portion, a second elastically deforming portion, a releasing member, and a protruding piece. The movable-side rail comprises an open-sectional portion including two side walls and a lid wall that couples the two side walls to each other. The lock portion is displaceable between a restraint position and a release position. The releasing member is engaged with the first elastically deforming portion. The protruding piece comprises an engaged portion with which the second elastically deforming portion engages.

A longitudinal adjuster (3) for a vehicle seat (1) includes at least one rail pair (7), including a lower rail (9) and an upper rail (11), which can be moved longitudinally in relation to the lower rail (9). At least one locking unit (13) locks the upper rail (11). At least one actuating element (5) releases the locking of the upper rail (11). The locking unit (13) includes at least one locking element (15) and at least one spring element (17), which are operatively engaged with each other. The spring element (17) is interlockingly and frictionally connected to the upper rail (11) by an insertion locking connection (S). The spring element (17) applies a preloading force to the actuating element (5) and to the locking element (15). A vehicle seat (1) is also provided with at least one such longitudinal adjuster (3).

A seat cushion adjuster in one aspect of the present disclosure comprises at least one bracket, at least one slider, and a plurality of interposing members. The plurality of interposing members is disposed between an inner wall of the at least one bracket and the at least one slider so as to interpose the at least one slider among the plurality of interposing members in an inner hollow portion of the at least one bracket. At least one interposing member of the plurality of interposing members comprises at least one supporting protrusion portion protruding toward the at least one bracket.

The present invention relates to a vehicle seat control apparatus and a control method thereof. The present invention is based on a structure in which a hall sensor is applied to a seat motor for providing an operation power of a power seat, and a seat caught situation is judged through a sensing operation of the hall sensor and a maximum current is supplied to the seat motor in the present invention. Therefore, the present invention has an advantage of solving the seat caught situation by improving the operation mode of the seat control apparatus to which the soft start mode is applied.
