Taxiing to Hold Short line to take off runway 33 Detroit City Airport. As I approached the Hold Short line I applied brakes to stop. My seat slipped back and my feet came off the brakes. It took several seconds to get my feet back on the brakes; but I traveled about 60 to 80 feet beyond the Hold Short Line. There was no other landing or departing traffic.
PA28 pilot reported a runway incursion when his seat slipped back while he attempted to apply brakes approaching the hold short line.
