For this type of aircraft they do recline but not as far as the other economy seats. The seat will recline until it hit the wall separating it from the galley.

A restricted recline seat is an airplane seat that has a limited range of motion or cannot recline at all. These are most commonly found in the row directly in front of an emergency exit row, as a reclined seat could potentially block the path or slow down passengers attempting to evacuate in an emergency. You will also frequently find restricted recline in the very last row of a cabin, where the seat back is flush against a bulkhead wall or a lavatory partition, leaving no physical space for the chair to move backward. In some cases, seats in front of large partitions (bulkheads) may also have their recline limited to prevent damage to the wall or to maintain consistent spacing. While these seats are often viewed as less desirable for long-haul comfort, they can sometimes be a benefit for the passenger sitting behind them, as they are guaranteed that their own personal space won't be encroached upon by a reclining seat. Travel sites like SeatGuru often mark these seats in yellow or red to warn passengers before they book.
