A structure of an auxiliary seat disposed in a second row in a vehicle is provided. The auxiliary seat storage structure includes an auxiliary seat that is disposed between a pair of exterior seats and has a seat back rotatably coupled to a seat cushion by a recliner and a rail that is installed in a vehicle width direction. The auxiliary seat is configured to slide into an internal cavity at a lower end of the exterior seat. The auxiliary seat slides along the rail when the auxiliary seat is folded and simultaneously adjusted downward and is stored in a lower cavity of the exterior seat. A passageway cavity is maximized, the number of operating steps are minimized and the auxiliary seat are stored regardless of whether an occupant is seated on the exterior seat.

A system for securing a passenger seat to a track can include a fitting coupled with or forming a portion of the passenger seat; a shear plunger coupled with the fitting including a shear plunger body defining a shear plunger locking surface; a guide pin assembly that may include a guide pin movable along a lift axis between a retracted state and an extended state and a locking member extending laterally from the guide pin that may travel in response to a movement of the guide pin from the retracted state to the extended state and may engage the shear plunger locking surface in response to a rotation of the guide pin in the extended state; and a quick install tool operable to raise and twist the guide pin assembly such that the locking member is held in tension against the shear plunger locking surface.

A latch assembly for a sliding seat includes a handle and a latch body fixed to the handle. The latch body is securable pivotally to one of an upper rail and a lower rail of the sliding seat. The latch body is pivotable via the handle between a locked position and an unlocked position. The latch body includes teeth openings arranged along a lengthwise dimension, where the teeth openings sequentially decrease in size. The assembly essentially eliminates problems associated with skip-locking and chucking in existing designs.

A slide rail by which a conveyance seat is slidably coupled to a floor of a conveyance includes: a lower rail attached on the floor; an upper rail slidably assembled to the lower rail and attached to the conveyance seat; and a locking spring supported by the upper rail and having a locking piece that is inserted into a locking slit formed in the lower rail to prohibit the upper rail and the lower rail from sliding relative to each other. The locking piece extends in a direction along a cross-section (the width direction) of the upper rail from a position in the locking spring, at which the locking spring is supported by the upper rail. The locking piece is inserted into the locking slit by deflection deformation of the locking piece in an in-plane direction of the cross-section (the height direction) of the upper rail.

A sliding device for a vehicle seat includes a pair of tracks, each having a lower rail and an upper rail, and a locking arrangement having a pair of locking assemblies, each including locking pins for locking a respective one of the upper rails to a respective one of the lower rails. The locking arrangement includes a releasing assembly for driving the locking pins of each of the locking assemblies to an unlocking configuration. The releasing assembly includes a releasing member and a pair of connecting members. The connecting members are each in a force transmission connection with the releasing member and with the locking pins of a respective one of the locking assemblies. The connecting members are entirely received within the tracks, and the releasing assembly is configured to convert rotational movement of the releasing member into linear movement of the locking pins of each of the locking assemblies.

The embodiments described and claimed herein are improved vehicle access systems. In particular, one embodiment includes three compact, motorized mechanisms for pivoting a passenger seat toward a door opening, extending the passenger seat outside the door opening, lowering the passenger seat, and tilting the passenger seat to help the passenger stand. The first mechanism concurrently pivots the passenger seat and moves it sideways during the pivoting operation so that it is aligned with the door opening. The second mechanism extends the passenger seat outside the door opening. The third mechanism lowers the seat.

The present invention relates to a sliding device for a vehicle seat provided with an improved locking arrangement. Said locking arrangement comprises a pair of locking assemblies (101a, 101b; 201a, 201b), one for each track of the sliding device, each including a plurality of locking pins (105a, 105b; 203a, 203b) suitable for locking the upper rails of the tracks to the respective lower rails. Said locking arrangement further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat. According to the invention, for any selected positions of the vehicle seat, all the locking pins (105a, 105b; 203a, 203b) of the locking assemblies simultaneously or quasi-simultaneously penetrate into corresponding apertures of the lower rails. Therefore, the invention advantageously allows to optimize the locking effect of the locking arrangement, as all the locking pins give their contribution to said locking effect.

A bench seating assembly for a vehicle includes an outboard seating assembly disposed on a pair of outboard rails slidably coupled to a pair of outboard tracks and an inboard seating assembly disposed on an inboard rail slidably coupled to an inboard track. A release bar assembly is disposed below the outboard seating assembly and the inboard seating assembly, and includes a driver movable between a first position and a second position. A latch mechanism is operably coupled to the driver such that if the driver is in the first position, then the latch mechanism is in a locked position, and if the driver is in the second position, then the latch mechanism is in an unlocked position.

A vehicle seat longitudinal adjustment device has a floor rail, a seat rail, and a locking unit substantially accommodated in a cavity formed by the rails, and a housing. A bearing shaft is disposed in this housing and extends in the displacement direction. The device includes at least two flat blocking parts, pivotable independently of each other about the bearing shaft and elastically biased, independently of each other, by one blocking spring each, and a releasing part. The structurally identical blocking parts each have two arms, between which the bearing shaft is located. The seat rail has, for each blocking part, shear slots accommodating the first and second arms. The floor rail has a perforated strip cooperating with the first arms, with first blocking slots, and a perforated strip cooperating with the second arms, with second blocking slots. The slots are periodically disposed one behind the other in the displacement direction.

A support member may be configured for selective connection with and removal from track assemblies. A support member may include a body and a rolling member rotatably connected to the body to facilitate movement of the support member along a track. The rolling member may include a grooved configuration to limit movement of the support member relative to said track in a Y-direction. The rolling member may include a groove configured to engage a protrusion or ridge of said track. The rolling member may include a first portion and a second portion separated in an axial direction by the groove.
