A seat for use in an aircraft having a floor is disclosed. The seat has a support assembly adapted to be secured to the floor, a seat having a central portion and a rear portion, a seat back pivotably coupled to the support assembly for movement between an upright position and a reclined position relative to the support assembly. A pivot assembly couples the central portion of the seat to the support assembly for permitting the seat to pivot about a pivot axis relative to the support assembly. A connector assembly couples the rear portion of the seat to the seat back for causing the rear portion of the seat to pivot downwardly about the pivot axis in unison with the seat back as the seat back moves from the upright position to the reclined position A method of construction of an aircraft seat frame is also disclosed. An armrest for an aircraft seat is further disclosed.
摘要:
A hydraulic vehicle seat adjustment system for providing positional adjustment of at least two seat adjustments of a vehicle seat. The system comprises a common source of hydraulic fluid, and a control unit which selectively controls and directs hydraulic fluid from the common source of hydraulic fluid to respective first and second actuators to adjust the respective different seat adjustments, for example fore and aft position of the seat, and seat back angle. The system may further also comprise a seat position determining unit connected to the control unit and to a common fluid flow sensor to determine the flow of hydraulic fluid from the common source of hydraulic fluid to the respective first and second actuators and to thereby determine the adjusted position of the respective actuators and so of the respective seat adjustment.

An assembly including a support housing and an actuator device. The actuator device includes an extendable initiator cup including at least one non-random fold and at least in part defining a storage chamber containing a reactive charge reactable to produce reaction products. The extendable initiator cup longitudinally extends from a first length to a second, greater length upon reaction initiation of the reactive charge. The extendable initiator cup is at least partially disposed within a longitudinally extending bore of the support housing. The support housing is effective to limit lateral expansion of the extendable initiator cup upon reaction initiation of the reactive charge. The assembly can include an electrical conductive member or an electrical switch. The extendable initiator cup can extend to sever the electrical conductive member or disengage the electrical switch, thereby interrupting the conduction of electricity through an electrical system. Alternatively, the extendable initiator cup can extend to engage the electrical switch thereby allowing the conduction of electricity through an electrical system.

The motion damper includes a damper wall, damper stages, and a damper head. The damper wall and damper stages are successively smaller in size and have a nested relationship. The damper wall and damper stages are each flexibly attached to an adjacent damper stage or the damper wall such that the damper stages may deploy in a telescopic fashion away from the damper wall. The damper head is attached to a smallest damper stage. As a result, the damper stages change in position relative to the damper wall and relative to each other to absorb the kinetic energy of objects attached to the damper head and damper wall.

A passenger seat which includes a seat bottom chassis assembled from a plurality of leg modules attached to fixed, spaced-apart attachment points on a supporting surface, and a plurality of beam elements for being carried by the leg modules. A plurality of clamp joints are positioned on a first side of the leg modules in a first laterally-offset relation thereto in a first spaced-apart relation to the attachment points of the supporting surface and for receiving the plurality of beam elements for defining a ladder frame assembly having a first specified width and seat spacing. The plurality of clamp joints are removable from the first side of the leg modules can positioned on a second, opposite side of the leg modules in a second laterally-offset relation for defining a ladder frame assembly having a second specified width and seat spacing while the plurality of leg modules maintain the same position relative to each other and thus to the fixed, spaced apart attachment points whereby the location of the seats may be altered while using the same beam elements.

A vehicle seat includes a seat cushion assembly for supporting an occupant seated thereon and a seat back cushion assembly for supporting the back of an occupant seated on the seat cushion assembly. A first mounting assembly is constructed and arranged to mount the seat cushion assembly on a vehicle floor and a second mounting assembly is provided which is constructed and arranged to mount the seat back cushion assembly on the seat cushion assembly. An adjusting mechanism is operatively embodied in one of the first and second mounting assemblies and is constructed and arranged to enable the cushion assembly mounted by the one mounting assembly to be moved in opposite directions through a range of adjustable positions with respect to the assembly on which the one mounting assembly mounts the cushion assembly. The adjusting mechanism also includes a locking and releasing device. A vehicle crash sensing system is operatively connected with the adjusting mechanism and is constructed and arranged to provide control of the movement of the cushion assembly mounted by the one mounting assembly in response to the sensing of a crash condition which occurs while said locking device is in the releasing position.
