The traditional pull up is a so-called `compound` exercise, which means it targets most of the muscle groups of the upper body (so basically it trains your entire upper body fairly equally). In my experience though, the muscles which grew tired the most after every pull up workout and in long-term grew the most were the obliques and shoulder muscles.

Chin-ups, just as most exercises use a primary & secondary muscle group. The primary muscle group would be the back (or latissimus dorsi). This is what helps to give that "V" - shape in the torso area. (along with slimming down the torso area, of course) The secondary muscle group would be the biceps. Depending on your grip position, you can focus either more on your "lats", or arms.
A pull up bar is used as a piece of equipment to build the upper body without the use of free-weights. Most people who use a pull up bar are attempting to increase upper body strength and muscle mass. A pull up bar is used to target the arms, chest, and core.

All pull-up variations will target the back muscles. It is an overall dominant back movement. The muscle group which will be worked hard are the lats and the traps. These are two of the larger muscle groups in the back. Almost all of the back muscles will assist in this movement. Also, your bicep and forearms will be involved and can be experienced as "sore" the day after doing pull-ups. The pull-up next to bent over rows and dead-lifts are considered to be a staple for back training.

Your diaphragm IS muscle. When we inhale, it is pushed down. When we exhale, it is pulled up.
