The present disclosure provides a seat track mechanism installed beneath a vehicle seat in order to move the vehicle seat in the forward and backward directions. A monotrack mechanism, to which a monopost structure and a single rail structure are applied, is installed at the bottom of the seat. The seat track mechanism includes a structure for hook-engaging lower and upper rails constituting the mono track mechanism by hook guides, thereby being capable of securing sufficient strength upon head-on or rear-end collision. The present disclosure also provides a seat track mechanism for a vehicle including a locking mechanism capable of enhancing stability of a passenger through structural reinforcement given at the bottom of the vehicle when it is necessary to ensure safety of the passenger in a situation such as collision or sudden stop or the like.

A vehicle seating assembly includes a seat base. A carriage is coupled to a lower surface of the seat base and includes a locating protrusion on a bottom surface thereof. The track assembly includes a rail. A rail cartridge is slidably engaged with the rail. The rail cartridge defines a locating hole for receiving the locating protrusion. A first electrical connector is coupled to the rail cartridge. A second electrical connector is coupled to the carriage and operable between engaged and disengaged positions. An actuation member is configured to move the second electrical connector between the engaged and disengaged positions. When the second electrical connector is in the engaged position, an electrical connection is formed between the first and second electrical connectors.

A vehicle seat including a fixed rail assembly, a translatable rail, and a translatable bracket. The fixed rail assembly includes a fixed rail and a fixed bracket extending from the fixed rail assembly. The translatable rail is configured to translate in a longitudinal direction along the fixed rail. The translatable bracket is fixed relative to the translatable rail such that the translatable rail and the translatable bracket translate in unison. The translatable bracket is configured to retain portions of the translatable rail within portions of the fixed rail. The translatable bracket includes a translating stop. The translatable rail is configured to translate between a first position in which the translating stop engages a fixed stop and a second position in which the translating stop is spaced apart from the translating stop.

A vibration-reducing insert is usable to reduce vibration or play between two metal aircraft components. The insert rotates on a fastener, and includes a shelf that projects into the gap and operates as an indexable cam to establish an appropriate compression in an engaged portion of the shelf.

A seat slider device may include: a lower rail attached to a body of a vehicle; and an upper rail attached to a seat and slidable with respect to the lower rail. The upper rail may include: a roller or a slider piece being in contact with a bottom plate of the lower rail; and a protrusion supporting the roller or the slider piece. The protrusion may be integrated with the upper rail.

A rail assembly can include a track assembly, an elongate shaft mounted to the track assembly, and a carriage assembly received within the track assembly. The carriage assembly can include a slider bracket. The slider bracket includes a first ramp portion and a second ramp portion. The first and second ramp portions are disposed on opposite sides of the slider bracket. The first and second ramp portions each define a receiving aperture. The elongate shaft is received through the receiving apertures of the first and second ramp portions.

An aircraft seat connector for mounting an aircraft seat to a mounting rail provided at a floor of an aircraft cabin comprises: a seat connection element for being mounted to the aircraft seat; and a base element for being mounted to the mounting rail. The base element comprises a seat coupling portion which is configured for receiving a mating portion of the seat connection element in at least two different spatial orientations, with the seat coupling portion thus allowing for arranging the seat connection element on the base element in at least two different spatial orientations.

A seat load detection method includes a process in which a control unit records a transition of a load detection signal and a transition of a seat load, a process in which the control unit specifies a timing when a load sensor detects a collision of a vehicle based on a transition record of the load detection signal, and a process in which the control unit calculates a correction value of the seat load based on a difference value between a stable seat load provided after the control unit detects the collision of the vehicle and a stable seat load provided before the load sensor detects the collision of the vehicle.

A safety device for a lock mechanism may have a housing that encapsulates the lock mechanism. The housing may have at least one opening, through which at least one adjustment element coupled to the lock mechanism is guidable. The at least one opening may have a sealing element. A seat track for a seat is also disclosed. The seat track may have a first track assembly with at least one track member, a second track assembly with at least one further track member, and a lock mechanism configured to lock an adjustment of the seat.

A rail assembly includes a track assembly with a retaining lip and a carriage assembly that is received within the track assembly. The carriage assembly includes a body portion, an exterior surface of the body portion, and a retaining bracket fastened to the exterior surface. The retaining bracket extends outwardly from the point at which the retaining bracket is fastened to the exterior surface. The retaining bracket defines a notch that receives the retaining lip of the track assembly.
