Aircraft seat

[Jeppy23]

I was told that these were old aircraft seeds I'm not sure from what era can anybody help me identify them? Thank you so much they are metal appear to be iron and look is the little legs went into a holster that held them in place

Highly unlikely that they would be aircraft - iron is too heavy. the arm rests would waste too much valuable space and legs are not braced or right configuration
