Abstract
Description
- The present disclosure relates to a seat closure mechanism, and more specifically, to a seat self-closing and retention system and method.
- Typically, commercial aircraft cabin attendant seats (CAS) are required to be self-closing and remain closed so the CAS does not interfere and/or block egress from the aircraft. This has typically been accomplished by using a flat or coiled torsion spring combined with a hydraulic damper. The spring provides the closing force, and the damper controls the rate of closure to prevent abrupt motion which can be noisy and possibly cause injury. An improved system is desirable.
- In various embodiments, a seat closure and retention system comprising a spring, a retention device, a seat, and a housing is disclosed herein. The system may include a tapered ramp surface configured such that as the anchoring device, such as a spring loaded device, approaches a notch and/or bowl shaped portion based on movement of the seat from a substantially horizontal portion to a substantially vertical position. Stated another way, in response to the pin and/or ball of anchoring device making contact with the tapered ramp surface a damper effect is achieved.
- According to various embodiments, a cabin attendant seat system may include a substantially stationary housing relative to the seat from which the seat is hingeably attached, a spring coupled between the housing and the seat configured to bias the seat to a stowed position, and an retention device coupled to a side surface of the seat configured to engage a shaped housing. The shaped housing may include a steeply curved surface and/or a tapered ramp.
- According to various embodiments, a method may include moving a hinged cabin attendant seat from a deployed position towards a stowed position via a torsion spring. The method may include dampening the movement of the hinged cabin attendant seat as the seat moves from the deployed position to the stowed position by interfacing a ball of a ball plunger with a ramp. The ball plunger may be housed on the seat and/or a surface coupled to the seat. The method may include anchoring the seat in a desired stowed position by engaging the ball of the ball plunger in a notch substantially adjacent to the ramp.
- The subject matter of the present disclosure is particularly pointed out and distinctly claimed in the concluding portion of the specification. A more complete understanding of the present disclosure, however, may best be obtained by referring to the detailed description and claims when considered in connection with the drawing figures, wherein like numerals denote like elements.

- Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step.
- According to various embodiments and with reference to
FIGS. 1 and 2 , aseat 120 closure andretention system 100 comprising force application mechanism, such as aspring 150, aretention device 175, aseat 120, and ahousing 135 is depicted.FIG. 1 depicts theseat 120 in a stowed position.FIG. 2 depicts theseat 120 in a deployed position. Thespring 150 may be configured to move a deployedseat 120 to a stowed position. For instance, thespring 150 may be a torsion spring. As depicted inFIGS. 1-3 ,spring 150 may be a generally flat length of material, such as a stainless steel length of material, which is configured to be fixed on one side, such as with abushing 310 and anchored to theseat 120 pan by asecond securing device 130, such as a bolt or screw. In this way, one side ofspring 150 is fixed to anon-moving housing 135, such asseat side panel 140, relative to the movingseat 120 while the other side ofspring 150 is attached to the rotatingseat 120. In response to torque exerted onspring 150 during rotation ofseat 120 relative tohousing 135,seat 120 movesseat 120 from the stowed position to the deployed position. Energy is stored in thespring 150 during the exertion of such torque. In response to the removal of torque exerted onspring 150,spring 150 causesseat 120 to retract back to the stowed position. -
Retention device 175 may be any desired device configured to temporarily retainseat 120 in a stowed position. For instance, as depicted inFIGS. 1-4 ,retention device 175 may comprise a spring loaded device such as a spring loaded ball plunger and/or simple detent mechanism. The spring loaded device may encapsulate a spring, such as a coil spring, in a body and comprise a plunger tip or ball on one end. This configuration enables accurate and repeatable end forces. Spring loaded devices may be configured for use where side loading is experienced. Spring loaded devices may provide repeatable projection of the plunger tip or ball. Theretention device 175 may be configured to interface with ashaped housing 125. - According to various embodiments and with reference to
FIGS. 1 and 2 ,retention device 175 may be coupled to aside panel 140 ofseat 120. For instance, the face ofside panel 140 may be oriented substantially normal to the face ofseat 120. In this way, as theseat 120 returns from a substantially horizontal level to the substantially vertical stowed position, aretention device 175 anchored on theside panel 140 may move in concert with the movement of theseat 120 for engagement with ashaped housing 125. Stated another way, theretention device 175 may move such that it aligns with ashaped housing 125.Retention device 175 may be configured to move in a same hinged arc of travel as theseat 120. Shapedhousing 125 may be any shape such that it forms a suitable location for contact withretention device 175. -
FIG. 3 depicts an exploded view of the elements ofFIGS. 1 and 2 . For instance,spring 150 may be coupled tohousing 135 via abushing 310, such as a metal bushing, coupled to a second bushing 315, such as a plastic bushing, which may be accessed by a keyingfeature 380 in thehousing 135.Bushing 310 may also be configured to facilitate the arc path pivoting movement ofseat 120. Seat 120 may pivot on a second metal bushing 312 configured to interface with a secondplastic bushing 319. - According to various embodiments and with reference to
FIG. 4 ,shaped housing 125 may comprise atapered ramp 185 surface configured such that as theretention device 175, such as a spring loaded device, approaches anotch 195 and/or bowl shaped portion based on movement of theseat 120 from a deployed position to a stowed position the ball shaped plunger tip may make contact with and gradually extend from its housing as the ball shaped plunger tip travels along thetapered ramp 185. In response to the pin and/or ball ofretention device 175 making contact with the taperedramp 185 surface, the speed of the self-closingseat 120 may be reduced. The friction of the taperedramp 185 may act to counter or dissipate the kinetic energy of theseat 120. Stated another way, in response to the pin and/or ball ofretention device 175 making contact with the taperedramp 185 surface, a damper effect is achieved. In this way, theseat 120 closure to the stowed position is slowed until the seat path of travel reaches a desired stowed position. Similarly, movement from the stowed position to a deployed position may be similarly damped as theretention device 175 makes contact with the taperedramp 185 surface until the pin is substantially and/or fully retracted within its housing. - A
notch 195 and/or bowl shaped portion of shapedhousing 125 may determine the desiredseat 120 stowing location. For instance, the depth of thenotch 195 and/or bowl shaped portion of the shapedhousing 125 is configured such that the tip of theretention device 175 is fully deployed. In response to theretention device 175 being fully deployed a force must be applied to both overcome a pre-load on thespring 150 and unseat the deployedretention device 175. In this way,seat 120 may remain stowed until pulled down from its stowed position and be biased to return to its stowed position without additional intervention (e.g., self-closing). An indicator, such as an audible indicator, visual indicator, and/or physical indicator may indicate that theretention device 175 is positioned a desired position, such as the fully stowed position. According to various embodiments,retention device 175 may comprise a secondary locking function, such as a safety that may be disengaged prior permitting theseat 120 to be moved from the stowed position to the deployed position.Seat 120 closure andretention system 100 may comprise a secondary locking mechanism to be disengaged prior permitting theseat 120 to be moved from the stowed position to the deployed position (as depicted inFIG. 7 ). In various embodiments,seat 120 closure andretention system 100 may comprise a secondary locking mechanism to retain theseat 120 in the deployed position. - According to various embodiments and with continued reference to
FIG. 4 , the shapedhousing 125 may further comprise a steeplycurved ramp 190 and/or surface past thenotch 195 and/or bowl shaped stowed position, configured such that the tip of theretention device 175 may travel past thenotch 195 and/or bowl shaped portion. The steeplycurved ramp 190 may aid in directing the anchoring device back towards thenotch 195 and/or bowl shaped portion to achieve the desired stowing position. This steeplycurved ramp 190 may be configured to reduce the noise of the anchoring device fully deploying and present a cushioning to theseat 120 path of travel. In this way, steeplycurved ramp 190, located beyond thenotch 195 with respect to the taperedramp 185. The steeplycurved ramp 190 may be configured to guide theseat 120 from an angle greater than 90 degrees as measured from the horizontal deployed position of theseat 120 to an angle that is less than or equal to 90 degrees. -
FIG. 5 depicts an example of the CAS in a deployed position. Steeplycurved ramp 190 and/or the taperedramp 185 may be configured to direct the movement of theseat 120 towards the desired stowed position as depicted inFIG. 6 . According to various embodiments, a plurality ofretention devices 175 may be utilized on two opposite sides of theseat 120 to engage with two generallyparallel housings 135. In this way, the size of theretention device 175 and/or thespring 150 may be reduced. Moreover, asecond retention device 175 may act as a fail-safe should oneretention device 175 fail to operate as intended. Unlike conventional CAS systems, a hydraulic damper is rendered redundant based on the reducedspring 150 size and utilization ofretention devices 175. - According to various embodiments,
retention device 175 may be configured to retainseat 120 in any desired location between deployed and stowed. Additionally, a detent system and/or additional shapedhousings 125 may be used to temporarily stow theseat 120 in additional positions. - According to various embodiments, the
lower spring 150 tension increases thespring 150 life-span.Seat 120 is safer and quieter operation as compared to conventional CAS systems due to the lower forces used to close theseat 120 inretention system 100. Theseat 120 is easier and safer to assemble due to not having to wind thespring 150 as tightly as conventional systems.Spring 150 may be anchored by bushing 310 safely by hand.Retention device 175 may be configured to retain theseat 120 closed in the event of aspring 150 failure.Retention system 100 is a lower cost design than conventicle CAS systems with fewer points of failure. - Benefits, other advantages, and solutions to problems have been described herein with regard to specific embodiments. Furthermore, the connecting lines shown in the various Figures contained herein are intended to represent exemplary functional relationships and/or physical couplings between the various elements. It should be noted that many alternative or additional functional relationships or physical connections may be present in a practical system.
