How well do they hold a leaf in the upright position? I'm contemplating using them in the van's counter for the lid over the chest fridge. This would keep the lid from hitting the window above the counter.

E-bay said to be self locking at 90* There is one that looks like this that locks flat, and 90* The language here is confusing, you might want to call.
I have seen others, not sure where they are sourced from though.

The very first project I ever made for my wife was a buttler's tray table. The hinges 'lock" in the upright position but not very strongly. They are pretty easy to flip down. If you are looking for something with a rigid feel to it in the locked position, these may not be the hinge to use in this case.

I dug out one of my old (~20 year old but new) butler tray hinges and put them in the 90 degree position. Using a force gauge it takes ~4.5 pounds of force to get them to go to the 180 degree position. A Blum European hinge (170 degree) takes about 15 pounds by comparison. Granted the mechanism is far, far different, but it gives an apples to oranges comparison.

Hinges need to be flat when open, like a sewing machine hinge.

Carolyn;
See the butler hinge here with a view of the spring.
Butler Hinge with spring view The hinge that Steve referenced for bi-fold doors has 4 detents or stops including one at 90° and 180°
If you have questions about the hinge let me know. I'm the manufacturers tech support guy for both.
Also available a butt hinge with a stop at 125° that may work and is much less money.
Lid Hinge All available from most sellers you know.

Imagine hinging part of your kitchen counter. Hinge must be mortised in flat with surface. Sewing machine hinge presents the best solid surface, but I'm intrigued by the ability to stand the lid at 90°. This would mean that the raised lid wouldn't rest on the window behind the counter.

Most bar tops that I've seen use mortise cylinder hinges in passageways. That said, if you plan to rest the hatch against a wall etc., a detent isn't needed but a solid brass hinge might be a good thought due to potential moisture. The butler table hinge is meant to hold a vertical 90° element the bi-fold door hinge is not.
Single pin flap hinges, sewing machine hinges and similar are also available either brass plated or solid brass. The "look" is available 3 ways. single or double pin, with and without a detent to hold open.
Personally, I would not use a double pin hinge in this application.
Have you given thought to a toy box hinge?

I can rest it against the window, but I'd rather not.
