The invention relates to device for providing a safety for passengers and to devices, providing the passenger comfort. There are disclosed variants of load limiter accomplishment for a restraint a passenger in a vehicle, which have a possibility to hold the preliminarily given force. The invention concerns a multi-passenger modular array oftiered passenger supports, having a several levels, means for attaching the modules, locking devices, attaching the modules to the vehicle floor, a drive mechanism for seats in the module, a mechanism for protecting the head of passenger, which is positioned on the seat. The means for providing the passenger comfort head are characterized by the position of steps in the modules, providing a sufficient space for free positioning the legs of the passenger in the upper and lower modules and in the zone of passage between rows. There are also disclosed the presence and position of the bins for storing packages, a construction of armrest and means for lighting, air conditioning, for information drop on the screen and for supplying an oxygen, in necessary.

Described is a seat track stud for attaching a passenger seat to a seat track having a first stud member, a second stud member, and a pin. The first stud member includes a base portion with at least one flanged edge, a first securing portion extending from the base portion and defining a first securing portion opening; and a second securing portion extending from the base portion at a location opposite the first securing portion and defining a second securing portion opening. The second stud member includes a connecting portion that defines a connecting portion opening and that is sized to fit between the first securing portion and the second securing portion. The pin extends through the first securing portion opening, the connecting portion opening, and the second securing portion opening.

A vehicle system includes a floor having a first side and a second side that is opposite the first side. The floor includes a plurality of openings. A seat is moveably supported on the floor. The seat includes a frame having a support member. An anchor system is mounted to the support member. The anchor system includes a selectively deployable anchor that secures the seat to the floor through one of the plurality of openings. A thermal control system is disposed in the seat. The thermal control system includes a duct having and inlet and an outlet. The inlet is selectively connectable to a vehicle based fluid supply system.

Embodiments of the present invention provide systems and methods for installing seats in a passenger vehicle using seat tracks and seat fittings. The seat track fittings may include a sleeve (22) with a cylindrical threaded opening (24), a double effect post (26) with an external lower thread (28) and an internal threaded portion (36). The external lower thread is configured to cooperate with the cylindrical threaded opening of the sleeve. The seat track fitting also has a track stud (38) with a lower flange (46) that is configured to cooperate with a seat track (10) and an upper external thread (42) configured to cooperate with the internal threaded portion of the double effect post. The double effect post external lower thread and the track stud external thread have inverse hands, such that rotation of the double effect post tightens the post and the track stud simultaneously.

A longitudinal adjusting device for a vehicle seat, includes a lower rail and an upper rail, wherein the upper rail is arranged longitudinally displaceably in the lower rail. The upper rail is engaged with the lower rail. A retaining and guiding element is designed, integrally formed or arranged on an upper edge of the lower rail. The element holds the upper rail on the lower rail in the operating position. At least two locking elements are arranged on and/or integrated in the upper rail and after same are unlocked. The upper rail and a vehicle seat attached thereto in a predefined position can be separated from the lower rail.

The invention proceeds from a seat fastening for fastening a seat, in particular an aircraft seat, to a fastening rail, with at least one base body, which is provided at least for a vertical fastening in the fastening rail, and with at least one horizontal-fastening element, which is slidable with respect to the base body at least between a locking position and an unlocking position. It is proposed that the seat fastening comprises at least one locking device, which is provided to fixate the at least one horizontal-fastening element in the unlocking position.

A seat leg assembly for a passenger seat, the seat leg assembly including: a seat leg member comprising a unitarily formed fitting member; and a plurality of stud members coupleable to the fitting member, wherein each of the plurality of stud members is formed of a material having an ultimate strength of at least 75 KSI.

A reclining aircraft seat structure, and associated aircraft cabin, the structure includes a base, a carriage, supported by the base, the carriage including a front edge and a rear edge, a seat pan support, articulated on the carriage about a transverse front axis, located between the front edge and the rear edge and a backrest support, articulated with respect to the seat pan support, about a transverse rear axis, located to the rear of the front axis. The structure also includes an actuator including a deployable rod between a retracted position and a deployed position, the deployable rod being articulated on a lower arm of the backrest support in a rear articulation point. The rear articulation point is located behind the front articulation axis over at least part of the travel of the deployable rod between the retracted position and the deployed position.

An aircraft seat may include an integrated tracking system. The tracking system may include at least one track foot and one or more roller bearings. The track foot may include one or more axles and be able to interface with a portion of an aircraft seat track. The one or more roller bearings may be coupled to the one or more axles of the track foot and interface with a top surface of the aircraft seat track to aid in the translation of the aircraft seat.

A seat beam for a rotary-wing aircraft adapted for receiving seat posts of a seat bench device, including a first seat beam end; a second seat beam end; and a seat beam body connecting both. A link with a link working line is arranged at the first seat beam end and includes: a link-beam fixation that is attached to the seat beam body and rotatable around a first link rotational axis that is perpendicular to the seat beam extension axis, and a first seat beam fixation that is connected to the link-beam fixation and adapted for being attached to the airframe attachment point such that the first seat beam fixation is rotatable around a second link rotational axis that is parallel to the first link rotational axis.
