A seat mounted on a slide slidable on a track. The track has comfort and entry zones. Pitch linkage mounts on the slide and supports a seat back. The linkage pivotally connects a seat back to the slide between recline and forward positions. A track latch fixes the slide to the track in a plurality of positions in the comfort zone. The entry zone is used to enter the vehicle. A forward stop blocks the slide from moving from the comfort to the entry zone. The forward stop moves between stop and release positions. The stop position blocks the slide from moving from the comfort to the entry zone. The release position does not block the slide from moving. A forward stop mechanism moves the forward stop into the stop position when the pitch linkage is in the recline position and the slide is in said comfort zone.

A passenger support includes vehicle seat having a seat base mounted to a track for sliding the seat base longitudinally. A sliding motion controller is provided. The seat base is movable from a slid-back configuration to a forward-seating configuration when the sliding motion controller is activated.

A vehicle slide rail device including a memory member defining a default seat position wherein, before operation of a release operation mechanism, the release operation mechanism is inserted into a concave portion formed in the memory member and recessed in a direction substantially perpendicular to a sliding direction and the release operation mechanism is in an engagement state of being engaged integrally with the memory member in the sliding direction, wherein, when the release operation mechanism is operated, the release operation mechanism pushes the concave portion in a direction substantially perpendicular to the sliding direction and removes the memory member from a state of defining the default seat position, and wherein, when a memory operation mechanism is operated, the memory operation mechanism removes the release operation mechanism from an inside of the concave portion and releases the release operation mechanism from the engagement state with the memory member.

A power adjuster (30) for adjusting the position of an upper track (16) relative to a lower track (18) of a seat track assembly (10). The power adjuster includes a lead screw (22) fixedly secured to the upper track, a drive assembly (32) operatively coupled to the upper track and selectively coupled to the lead screw, a driven assembly (34) operatively coupled to the lead screw and selectively coupled to the drive assembly, and a release mechanism (36) coupled to the upper track. The release mechanism is operable between a locked condition coupling the driven assembly to the drive assembly and the upper track wherein the driven assembly and the drive assembly move longitudinally along the lead screw with the upper track relative to the lower track and an unlocked condition wherein the driven assembly is decoupled from the upper track and retained along the lead screw during movement of the upper track relative to the lower track.

A seat track assembly provides forward and rearward movement of a seat assembly. A latch mechanism allows movement of a movable track between a plurality of positions. A memory mechanism with a memory plate and a memory tab are operable between a home position in which the memory tab is disposed in a recess of the moveable track, and a memory position in which the memory plate is coupled with a plurality of angled teeth to define a selected position. Actuation of the memory mechanism to the memory position unlocks the latch mechanism to allow movement of the movable track in a first direction away from the selected position to an easy-entry position. Movement of the movable track in a second direction from the easy-entry position stops the movable track at the selected position, allowing the latch mechanism to lock and the memory mechanism to return to the home position.

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 conveyance seat is provided. The conveyance seat comprises a first side frame portion disposed in a first side of a seat width direction extending substantially in an up-down direction, a second side frame portion disposed in a second side of the seat width direction extending substantially in the up-down direction, a drive mechanism configured to generate driving force so as to pivot the first side frame portion and the second side frame portion in the front-rear direction of the seat, a walk-in mechanism disposed in an opposite side of the drive mechanism in the seat width direction across the first side frame portion, a motor fixing portion disposed on the first side frame portion and provided with a fixing surface on which the drive mechanism is secured and a bracket configured to secure the drive mechanism to the fixing surface.

A vehicle seat sliding apparatus includes a lower rail, an upper rail, a slide-lock mechanism that pivots the lock member to a slide-lock position and holds the upper rail in a slide-lock state, and a slide-lock cancellation unit moved by operation of an operation member in a longitudinal direction of the upper rail to cancel an action of the slide-lock mechanism. The slide-lock cancellation unit includes a drive unit and an inclined surface arranged in the drive unit. The drive unit is supported by the upper rail so as to be slidable in the longitudinal direction of the upper rail. Operation of the operation member slides the drive unit. The inclined surface pivots the lock member to a slide-lock cancellation position when sliding.

A seat assembly comprises a seat adjuster; and a seat including: a seat base connectable with a track assembly; a seat bottom pivotably connected to the seat base at a first pivot axis; a seatback pivotably connected to the seat base at the first pivot axis; and an adjustment member pivotably connected to the seat base at a second pivot axis and pivotably connected to the seat bottom at a member-bottom pivot axis. The seat adjuster is connected to the seat to adjust the seatback about the first pivot axis, the seat bottom about the first pivot axis, and the adjustment member about the second pivot axis to adjust the seat to a first seat position and to a second seat position.

A vehicle slide rail device including: a memory mechanism which includes a memory member configured to define a default seat position by engagement; a release operation mechanism which is configured to release a lock mechanism from a locked state and slide together with the memory member in a slide direction by removing the memory member from a state of defining the default seat position; a memory operation mechanism which is configured to release the lock mechanism from the locked state while leaving the memory member in the state of defining the default seat position; a cancel mechanism which is pressed against the memory member to cancel the releasing of the lock mechanism by the memory operation mechanism and return the lock mechanism to the locked state when the seat position is returned to the default seat position defined while an operated state of a memory operation member is maintained.
