Emergency Exit Row Seats
Are there any regulations on how exit row seats have to be configured? In the past few months I have seen just about everything flying DL, US, AA, WN, CO, and NW and I know there are probably more out there. Things I notice that are different: tray tables, window shades, forward seats recline, window seat arm rest, and smaller seat cushions on window seats. Are there rows not to code or is it just up to the interior designer as to what they feel is safer?

Depends on the exit door type, seat configuration, number of exits and passenger capacity.
There are lots of regulations. Here's the main rules for transport category aircraft:
There are lots of regulations. Here's the main rules for transport category aircraft:
(c) The following must be provided for each Type III or Type IV exit--
(1) There must be access from the nearest aisle to each exit. In addition, for each Type III exit in an airplane that has a passenger seating configuration of 60 or more--
(i) Except as provided in paragraph (c)(1)(ii), the access must be provided by an unobstructed passageway that is at least 10 inches in width for interior arrangements in which the adjacent seat rows on the exit side of the aisle contain no more than two seats, or 20 inches in width for interior arrangements in which those rows contain three seats. The width of the passageway must be measured with adjacent seats adjusted to their most adverse position. The centerline of the required passageway width must not be displaced more than 5 inches horizontally from that of the exit.
(ii) In lieu of one 10- or 20-inch passageway, there may be two passageways, between seat rows only, that must be at least 6 inches in width and lead to an unobstructed space adjacent to each exit. (Adjacent exits must not share a common passageway.) The width of the passageways must be measured with adjacent seats adjusted to their most adverse position. The unobstructed space adjacent to the exit must extend vertically from the floor to the ceiling (or bottom of sidewall stowage bins), inboard from the exit for a distance not less than the width of the narrowest passenger seat installed on the airplane, and from the forward edge of the forward passageway to the aft edge of the aft passageway. The exit opening must be totally within the fore and aft bounds of the unobstructed space.
(2) In addition to the access--
(i) For airplanes that have a passenger seating configuration of 20 or more, the projected opening of the exit provided must not be obstructed and there must be no interference in opening the exit by seats, berths, or other protrusions (including any seatback in the most adverse position) for a distance from that exit not less than the width of the narrowest passenger seat installed on the airplane.

(ii) For airplanes that have a passenger seating configuration of 19 or fewer, there may be minor obstructions in this region, if there are compensating factors to maintain the effectiveness of the exit.
(3) For each Type III exit, regardless of the passenger capacity of the airplane in which it is installed, there must be placards that--
(i) Are readable by all persons seated adjacent to and facing a passageway to the exit;
(ii) Accurately state or illustrate the proper method of opening the exit, including the use of handholds; and
(iii) If the exit is a removable hatch, state the weight of the hatch and indicate an appropriate location to place the hatch after removal. (3) For each Type III exit, regardless of the passenger capacity of the airplane in which it is installed, there must be placards that--
