I'm making a 2D platformer with Box2D. The player needs to be able to grab onto a ledge and pull him/herself up.

Right now I have a sensor that extends in every direction from the upper half of the player's body.

The logic seems simple enough: if there are tiles inside the sensor and empty space above them, then it's a ledge and the game should act accordingly. The problem is that I can't figure out how to implement that logic with Box2D.

Anyone have any ideas?
