Mid/rear Seats Assembly problems of the 2008 Mazda Tribute

The bars of the front head rests protrude from the rear of the seat as there is no protection between the bars and the cloth of the seat. Because of this, it is very easy for one to hit their legs/knees when entering and exiting the vehicle. My main concern is that it seems like there could be a very high potential for serious leg/knee injuries in the case of an accident. I believe this problem can affect young teens to adults as my mom, who is only 5' 1" tall, easily hit one of the bars with her knee as did I when getting in and out of the back seats.
