A front upper support surface and a rear upper support surface facing an upper surface of a rear end of an operation handle are provided in a lock release lever with a gap between the front upper support surface and the rear upper support surface in the vehicle front-rear direction, and front lower support surfaces are provided below the front upper support surface. An upper rail is provided with a rear lower support surface, which is positioned below a rear upper support surface. A clearance is provided between the front lower support surface and a lower surface of a rear end of the operation handle, and a clearance is provided between the rear lower support surface and the lower surface of the rear end of the operation handle.

A fastening arrangement of a seat on a rail arrangement may have a modular construction and may have one lock module for releasably arresting the fastening arrangement on the rail arrangement. The fastening arrangement may also have one lock unlocking module for unlocking the lock module. The fastening arrangement may also have one rail unlocking module.

The present disclosure provides a seat rail locking device for a vehicle, which may apply a method of moving a lock pin in an upward direction to lock a seat rail by moving away from a conventional seat rail locking method of moving the lock pin in a directly downward direction to pass through a floor panel, thereby not causing the interference with the floor panel at all to flexibly apply a battery mounting structure to the floor panel, improving an assembling property as an operator may easily assemble a lock pin guide configured to guide the lock pin to move in upward and downward directions to a movable rail with only one-touch operation, and preventing the lock pin from being damaged or separated by mounting a cap at an upper end of the lock pin.

In order to prevent distortion of slide rails caused by an urging force generated by an urging member in a vehicle tumble seat, a vehicle seat is capable of taking a stowed position in which a seat back 6L is folded onto a seat cushion 5L and the seat cushion 5L together with the folded seat back 6L is rotatably lifted away from a floor 3, and the vehicle seat is configured to include: a support member 31 coupled to the floor; a rotating member 33L rotatably supported by the support member via a support shaft extending in a right-left direction; a lower rail 41 extending in a front-rear direction and coupled at an end to the rotating member so as to be extend literally offset relative to the support shaft; an upper rail 42 slidably supported by the lower rail and coupled to the seat cushion; a coupling device 51 provided at a second end of the lower rail on a side toward the support shaft and capable of selectably connecting to the floor; and an urging device 60 extending the front-rear direction and having one end coupled to the support member and a second end coupled to the lower rail on the side toward the support shaft side, wherein the urging device is configured to be expandable and contractible in a longitudinal direction thereof so as to urge the seat cushion in such a direction as to rotate about the support shaft away from the floor.

A lock assembly for a vehicle seat includes a lever that has a body and a retention tab that extends from the body, a biasing member that is operably coupled to the body of the lever, an engagement member that is proximate to the lever, and an inertia member that has a weighted head and a retention hook. The inertia member is operable between a first position and a second position.

A floating seat may have at least one seat shell with a seat surface region and a backrest region. The seat may also have a base element on which the seat shell is arranged in an adjustable manner, and an adjustment mechanism for adjusting the seat shell relative to the base element and/or a seat base. The adjustment mechanism has at least one adjustment unit for adjusting the seat shell and at least one drive unit which is designed to lock the base element and the seat shell in place in a self-locking manner. The lock can be released by a force introduced into the adjustment unit by an occupant sitting in the seat shell via said seat shell as well as by a force introduced into the adjustment unit by the drive unit.

A rail for a vehicle seat having first and second sliding rail members driven by a motorized drive mechanism. The rail further comprises a mechanical lock actuated by a relative movement between the motorized drive mechanism and the second rail member in the event of an accident.

A sliding device for a vehicle seat is provided. The sliding device includes a pair of parallel slideways, each of which comprises a lower rail, an upper rail slidably mounted to the lower rail and a latch for allowing/preventing a movement of the upper rail relative to the lower rail. A releasing member is provided for driving the latches to a position in which the upper rails are free to move relative to the lower rails. Each latch has a rear portion which is bent into a “U”-like shape and comprises a lower leg carrying latching elements configured to cooperate with corresponding latching elements provided in the lower rail and an upper leg configured to engage the releasing member. The design of the latches improves the reliability of the sliding device.

An alternative seating arrangement of a vehicle with a variety of vehicle restraints and occupant safety systems that are associated with the alternative seating arrangement. Many embodiments include rear facing and side facing seats.
