A seat sliding apparatus for a vehicle includes a lower rail, an upper rail supported to be movable relative to the lower rail, and a pressing member attached to one of the lower rail and the upper rail via a biasing member. The pressing member constantly presses the other of the lower rail and the upper rail by a biasing force of the biasing member. The lower rail and the upper rail extend in a first direction. The pressing member obliquely presses the other of the lower rail and the upper rail so that force components are generated in both the first direction and in a second direction orthogonal to the first direction.

A track assembly includes a first track having a first inner surface, a first support coupled to the first inner surface, a second track having a second inner surface, and a second support coupled to the second inner surface. The second track is slidably coupled to the first track. The first support has a first free end that extends from the first inner surface at a downward sloping angle. The second support has a second free end that extends from the second inner surface at an upward sloping angle. The first support and the second support are positioned such that the second free end is disposed above the first free end.

A seat slider device may include a lower rail attachable to a body of a vehicle; and an upper rail attachable to a lower portion of a seat and slidably engaging with the lower rail. The upper rail may include a lock pin movable along a short direction of the upper rail. The lower rail may include a plurality of first holes and a second hole. The first holes may be arranged along a longitudinal direction of the lower rail and configured to engage with the lock pin, and the second hole may be arranged with the first holes along the longitudinal direction of the lower rail. The second hole may be positioned at a position where the lock pin is incapable of engaging with the second hole or the second hole may have a size with which the lock pin is incapable of engaging.

A vehicle seat in the present disclosure includes a seat cushion; a seatback; a sliding device configured to slidably support a seat main body that includes the seat cushion and the seatback; a first locking mechanism configured to restrict a sliding movement of the seat main body when the seat cushion and the seatback are placed in an occupiable state; a tip-up mechanism configured to rotationally displace the seat cushion in conjunction with a frontward tilting movement of the seatback; and a second locking mechanism configured to restrict a sliding movement of the seat main body when an elevation angle of the seat cushion exceeds a preset angle by an operation of the tip-up mechanism.

A removable component system may include a removable component selectively connectable to a mounting surface including a component electrical unit; an antenna; a system controller configured to communicate with the component electrical unit and the antenna; and/or a track assembly configured to be fixed to said mounting surface. The removable component may be selectively connectable to said mounting surface via the track assembly. The removable component may be configured for selective connection with, removal from, and movement along the track assembly. The system controller may be configured to obtain a position of the removable component relative to said mounting surface via the antenna and the component electrical unit (e.g., via a component controller, a sensor, and/or a communication device thereof).

A support assembly may be configured for connections with, adjustment along, and removal from a track assembly. The support assembly may include a support member and/or an electrical connector. The electrical connector may be adjustably connected to the support member and adjustable to a first position and a second position relative to the support member. The electrical connector may include a first contact configured to engage a first conductor of said track assembly. The first contact may be engageable with said first conductor when the electrical connector is in the first position. The electrical connector may be configured such that the first contact is disposed at a distance from said first conductor when the electrical connector is in the second position. The first contact may be movably connected to the electrical connector such that the first contact is movable relative to the electrical connector and the support member.

A seat position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle. The seat position detection apparatus has a lock for the longitudinal setting of the seat rail and the floor rail in relation to one another, and a mechanical memory device that has a position determination unit and a position detection unit, which may be started symmetrically from both directions of the longitudinal adjustment of the vehicle seat to define a vehicle seat position.

A seat slide device that can adjust sliding resistance of sliding of an upper rail with respect to a lower rail in an unlock state is provided. The seat slide device is provided in a vehicle and includes a lower rail fixed to a floor of a vehicle, an upper rail fixed to a seat of the vehicle and supported to be capable of sliding with respect to the lower rail, a lock mechanism configured to switch a lock state in which movement of the upper rail is restricted and an unlock state in which the movement of the upper rail is allowed, and an adjusting mechanism configured to adjust sliding resistance of sliding of the upper rail with respect to the lower rail in the unlock state.

A vehicle seat slide mechanism via which a seat assembly is slidably mounted on a vehicle floor is provided with: a lower rail that is mounted on the vehicle floor; an upper rail which is slidably attached on the lower rail and on which the seat assembly is attached; a lock mechanism that locks the upper rail on the lower rail in a releasable manner; and a gap reduction member that is provided between a first face formed at the lower rail and facing in a substantially vertical direction and a second face formed at the upper rail and facing to the first face.

A longitudinal adjuster (3), for a vehicle seat (1), includes a lower rail (9), an upper rail (11), moveable in relation to the lower rail (9) in a longitudinal direction (x), and a locking unit (13) for locking the upper rail (11) to the lower rail (9). The locking unit (13) includes two locking elements (VR), which, in order to lock the upper rail (11) and the lower rail (9), engage in the upper rail and the lower rail in a blocking manner in steps such that one of the locking elements (VR) pre-locks the upper rail (11) and the lower rail (9) with play in a pre-locking step and one of the locking elements (VR) locks the upper rail (11) and the lower rail (9) without play in a locking step. A vehicle seat (1) including such a longitudinal adjuster (3) is provided.
