Abstract: A passenger seat frame assembly, including a seat bottom chassis including a plurality of leg modules and section assembly modules. The leg modules are attached to fixed, spaced-apart attachment points on a supporting surface, such as the deck of an aircraft fuselage. A plurality of beam elements are carried by the leg modules and section assembly modules. A plurality of clamp joints are provided for being positioned on the plurality of leg modules and for receiving the plurality of beam elements in spaced-apart relation to each other for defining a ladder frame assembly having a specified width and seat spacing.

Abstract: The seating system of the preferred embodiment of the invention has been specifically designed for a vehicle having a deceleration sensor adapted to sense a deceleration event of the vehicle. The seating system of this preferred embodiment includes a seat assembly, a tilting mechanism adapted to tilt the seat assembly, and a control unit coupled to the deceleration sensor and adapted to activate the tilting mechanism upon the sensing of a deceleration event.

Abstract: A leg assembly for a vehicle passenger seat comprises a front leg frame and a rear leg comprising a first link pivotally connected at a first end to the rear foot, a second link pivotally connected at a first end to an intermediate point on the leg frame and a load-limiting strut pivotally connected at a first end to the front foot and pivotally connected at a second end to both the second end of the first link and the second end of the second link. The load-limiting strut is arranged to resist movement of the first and second links into alignment with each other, but to yield when subject to a load exceeding a predetermined value, thereby allowing the seat to pivot forwardly about its front foot.

Abstract: An integrated child's seat (10) is provided for a motor vehicle seat. The child's seat (10) is displaceable between a low and an unfolded raised position. It has a base portion (12) and a support portion (14) which are pivotably connected by front and rear parallelogram arm devices (16, 18). A diagonal strut device (40) is linearly movably guided with a guide end portion (42) along a guide device (44) provided on the support portion (14) or on the front parallelogram arm device (16). The diagonal strut device (40) is pivotably connected with its second end portion (52) to the rear parallelogram arm device (18) by a pivotal connection (58). The rear parallelogram arm device (18) has a weak crash location (38) so that in the unfolded condition of the child's seat (10) with a corresponding weight on the support portion (14), the rear parallelogram arm device (18) buckles at the weak crash location (38) and the support portion (14) dips downwardly with its rear end part.

Abstract: A child safety restraint system is disclosed for use on private and commercial aircraft. The invention includes a removable, portable strap assembly for safely securing automotive child safety seats to aircraft seats and frames in compliance with present and pending federal aviation safety regulations. A system is disclosed which includes a pair of anchors attached to the front beam on an aircraft seat. A pair of connectable and adjustable belt assemblies are attached one each, to the anchors. One belt assembly is passed through the frame of a child safety seat and connected to the other belt assembly. The combined length of the connected belt assemblies is then adjusted to place the system in tension, and thereby secure the child safety seat to the aircraft seat. The resulting system provides significantly improved safety for children over the use of the lap belts to secure child safety seats in commercial aircraft.

Abstract: A vehicle seat frame includes a locking device that prevents the seat frame from moving during a crash. A first spring holds an inertia-sensitive locking element and an interlocking element in a first position. In the event of a crash, the inertia-sensitive locking element swivels about an axis due to the force of inertia. Contact surfaces on the inertia-sensitive locking element and the interlocking element disengage. A second spring then pulls the interlocking element toward a guide link. A gear region on the interlocking element grips into and engages with a gear region on the guide link. The second spring maintains the tension on the gear regions, even if the force of inertia has dwindled. The locking device can be disengaged only by manually resetting the interlocking element and the inertia-sensitive locking element into the first position.

Abstract: The seating system of the preferred embodiment of the invention has been specifically designed for a vehicle having a deceleration sensor adapted to sense a deceleration event of the vehicle. The seating system of this preferred embodiment includes a seat assembly, a tilting mechanism adapted to tilt the seat assembly, and a control unit coupled to the deceleration sensor and adapted to activate the tilting mechanism upon the sensing of a deceleration event.

Abstract: A side facing, multi-passenger aircraft divan assembly having a seat pan support assembly, with a front end, a rear end, a first side and a second side, and defining at least two passenger seating zones, a seat back assembly operatively coupled to the seat pan support assembly, and a base assembly extending downwardly from the seat pan support assembly into secure engagement with an underlying support surface of the aircraft. The adjacent passenger seating zones are spaced 27 inches from mid point to mid point of one another so as to prevent hazardous contact between passengers disposed in adjacent passenger seating zones during a longitudinally directed impact on the divan assembly.

Abstract: A car seat having a seat portion linked by means of connecting rods to a rail for longitudinal adjustment has a dampening element to transform kinetic energy into frictional or deformation energy. The dampening element is embodied as a separate component and has, on the one hand, an articulated link to a component on the seat portion as well as, on the other hand, to another component on the rail for longitudinal adjustment. The components include a threaded rod and a nut that can rotate around it, as well as a sleeve-shaped component that surrounds at least a part of the nut. The nut can be moved longitudinally relative to the sleeve-shaped component while overcoming a force of friction or deformation.

Abstract: A leg assembly for a vehicle passenger seat comprises a front leg frame and a rear leg comprising a first link pivotally connected at a first end to the rear foot, a second link pivotally connected at a first end to an intermediate point on the leg frame and a load-limiting strut pivotally connected at a first end to the front foot and pivotally connected at a second end to both the second end of the first link and the second end of the second link. The load-limiting strut is arranged to resist movement of the first and second links into alignment with each other, but to yield when subject to a load exceeding a predetermined value, thereby allowing the seat to pivot forwardly about its front foot.

Abstract: A locking device for a vehicle seat with a seat frame and a seat height adjustment device has two guide links fixed to the body, with a swivel support on a horizontal axis. The guide links can swivel in different angular positions for adjusting the height of the seat. One guide link has a geared unit for swiveling it, while both the guide links are connected to each other by means of a connecting rod so that they do not rotate with respect to each other. A locking device with an inertia-sensitive element works on the side opposite to that of the geared unit between seat frame and adjacent guide link. A spring working on the inertia-sensitive element keeps the locking device in the normally unlocked position. The inertia-sensitive element is a locking element for latching with an interlocking element.

Abstract: Chair structure (1) for a vehicle comprises a backrest (2), a seat (3) which has a front part (31) and a rear part (32), a support (4) which carries the squab (3), and means (10) to fasten the support to a vehicle floor. The chair structure (1) also includes a means (6) that makes the backrest (2) tilt forwardly relatively to the squab (3) in the event of an accident.
