Provided is a slide lock structure for a slide rail device which can produce a reliable locked state with a high and reliable mechanical strength by using a simple structure. The slide lock structure includes a casing, a pair of lock members provided on the casing, and each provided with a cam surface formed on an outer side thereof, and engagement projections projecting laterally outward so as to be laterally movable between an engaged position in which the engagement projections are received in the slots, and a disengaged position in which the engagement projections are dislodged from the slots, a compression coil spring urging the lock members toward the engaged position, and an operating member provided on the casing in a movable manner, and provided with a cooperating cam surface slidably engaging the cam surface such that the lock members are moved to the disengaged position against a biasing force of the compression coil spring as the operating member is moved vertically.

A translation assembly for a vehicle includes a rail assembly that defines a first channel, a second channel, and a central member that extends between the first and second channels. A carriage assembly couples to the rail assembly. The carriage assembly is movable relative to the rail assembly. The carriage assembly includes a first rail engagement structure that extends into the rail assembly and is received within the first channel; a second rail engagement structure that extends into the rail assembly and is received within the second channel; and a carriage housing that is coupled to the first and second rail engagement structures. The carriage housing extends between the first and second rail engagement structures. The carriages assembly also includes one or more drive assemblies that engage with a top surface of the central member of the rail assembly.

Provided is a sliding device which can avoid unintended locking release without depending on an excessive engagement force of an engagement member. The sliding device includes a lock mechanism that locks an upper rail to a lower rail. The lock mechanism includes: an engagement member that shifts in the upper rail between a locking position and a release position; a first urging member that gives an urging force to the engagement member in a direction from the release position to the locking position; and an operation member for shifting the engagement member from the locking position to the release position. The operation member comprises a shift restrictor that keeps the engagement member from shifting to the release position when the engagement member is in the locking position.

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 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 power long rail assembly is attached to a vehicle floor for repositioning vehicle seats in a vehicle between a plurality of seating positions. The power long rail assembly includes a fixed long rail and a power rail drive assembly configured to travel along the fixed long rail. The power rail drive assembly has an upper channel having a driving wheel configured to frictionally and/or meshingly engage with the fixed long rail, a fore/aft motor operatively coupled to the driving wheel, a latch assembly for locking the upper channel to the fixed long rail, and a latch release mechanism having a latch motor operatively coupled to a release plunger for automatically unlocking the latch assembly from the fixed long rail, and a fore/aft button operatively coupled to the fore/aft motor and to the latch motor to selectively activate the fore/aft motor and the latch motor.

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, and a releasing member. The lock portion is displaceable between a restraint position and a release position. The elastically deforming portion comprises: a linear portion that is an elastically deformable portion extending in a direction approximately parallel to a longitudinal direction of the movable-side rail; and an engaging portion protruding from an extending-direction leading end portion of the linear portion in a direction approximately perpendicular to an extending direction of the linear portion. The releasing member comprises: a first engaged surface that is contactable with the engaging portion from one end side in the extending direction; and a second engaged surface that is contactable with the engaging portion from the other end side in the extending-direction.

Provided is a seat sliding device. The seat sliding device comprises a fixed-side rail, a movable-side rail, a lock portion, an elastically deforming portion, a releasing member, and a restricting portion. The movable-side rail comprises an open-sectional portion including two side walls and a lid wall. The lock portion is displaceable between a restraint position and a release position. The releasing member is provided between the elastically deforming portion and the lid wall. The restricting portion is configured to provide a space through which an insertion-side end of the releasing member is insertable between the elastically deforming portion and the lid wall.

A release device for the upper rail and the lower rail of a longitudinal seat adjustment system of a motor vehicle seat, the release device having a lever rotatably supported on the upper rail of the seat. An end of the lever interacts with the locking means and optionally releases the locking means. A handle is provided at the other end. If the handle is operated, the lever moves relative to the upper rail from a passive position to a release position and moves the locking means from a locking position to a releasing position. So the release device automatically moves into a passive position of the release device, a spring element is provided, which preloads the lever into the passive position of the lever. The spring element additionally supports the lever on the upper rail.

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.
