Odd question from non-mechanic.

So I have some older airline seats that could easily be used around the house but they have a powered recline feature...and that's the only way they'll recline. The connector looks like this:

Any ideas on how I could power this sucker?

Welcome to the site docrok!

All seats I have worked on do have a manual lever to move them when the power is out or broke.

The problem you will have if supplying the proper voltage to them.

Aircraft use different volts and freqs then household.

DC - 28 volts
AC -115volts @ 400 hertz

Ref www.wonderquest.com

Home use 115 volts @60 hertz in the US

Hooking something made to run at 400hertz will be soon be smoking when trying to run with a 60hertz supply.

You would also need to know if the chair was made to run on DC or AC.

As for the cannon plug issue. You could just cut it off and hard wire it to your power source.

You are showing an audio multiplex entertainment plug for the audio controls in the chair and no it is not usable at home unless you have 50k.

IN answer your chair question you should have a plug with 3 large pins in the triangle shape inside a round plug the size of a half dollar.
TO power the chair you NEED a power supply that outputs 28V DC fused or breakered AND then you that to power a 114V AC 400 HZ inverter FUSED OR BREAKERED with adapter cable and mating plug for chair. I WOULD go to a local AVIONICS REPAIR STATION not a FBO or A&P for they are most suited to serve this type of problem. Tell them that you do not care if set up is used, if 90 day warranted, for many used parts of this type are floating around. ALSO PLEASE DO NOT BOTHER THEM IF YOU ARE NOT READY TO PAY AT LEAST $65 an hour for these are hard working people that are ON THE CLOCK.

A delayed thanks. Found the 3 pin connector near the base of the seats that fits your description. (Also found a boarding pass stub from a TWA flight in 96...ha!).

I'll try and search out an Avionics Repair Station. I'd be more than happy to pay, but am wondering how long it might be to assemble it all. Any idea? Ballpark??

Thanks again. Very helpful info.

I do not know how long it would take to hunt up the parts surplus, a TWA seat is probably common among airline industry majors using common parts, and you should ask around about wire gauge and pin layout and breaker AMPS. You should be able to ask around avionics repair station web sites and find out. If you are still having trouble, let me know and I will ask around. I do not think it would be a big deal but you never really know how cold the water is until you jump in.

PS, These seats are heavy so try not to move it by the leg rest or back for this could damage the mechanical actuators or mechanisms that articulate the chair.

So...I must be on the totally wrong path. Found what I thought were avionics repair stations, but couldn't find a soul who seemed to know one thing from the other. Know of anything in the Ft. Lauderdale area?

Here is a pic of what I believe is the connector:
