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.

An aircraft seat fastening assembly, due to the use of electroactive polymers, facilitates the compensation of tolerances and the fastening of aircraft seats in the passenger cabin of the aircraft. A fixing actuator contains the electroactive polymer and can be switched electrically between a fixed state, in which a movement of a fastening region is not possible, and a non-fixed state, in which a movement of the fastening region is possible in a vertical direction. The aircraft seats can thereby be displaced in a continuously variable manner along the aircraft seat fastening rail. The aircraft seats can also be locked in a fully automated manner, and possibly from a central location. It is also conceivable to individually control the aircraft seats and/or the group(s) of seats.

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.

There is provided a vehicle seat passenger protection structure, including: rail members that are fixed to a floor of a vehicle, and have, in lower surfaces thereof, slit portions that extend in the seat longitudinal direction; sliding members that are connected to a lower portion of a seat cushion, and are disposed at interiors of the rail members, and are supported so as to be slidable in the seat longitudinal direction by the rail members; and upward movement suppressing members that include main body portions, which are disposed so as to face lower surfaces of the rail members, and fixing portions, which project out toward a seat upper side from the main body portions and pass through the slit portions and are fixed to lower surfaces of the sliding members, and that can move in the seat longitudinal direction following the sliding members.

A system for locking a slide rail for a vehicle seat with continuous adjustment, comprises a fixed rail, and two blocking members urged towards each other by an elastic member to ensure their bracing on the rail, as well as to an unlocking mechanism comprising an unlocking member ensuring the release of the sliding of the slide rail by a separation of the two blocking members.
