Abstract
A system to attach seats, in particular rows of lightweight seats to the light gauge deck of a high passenger marine craft. Horizontal flanges of aluminum angles (23) form a T-shaped foot locking within cavity (35) of track (29) fixed to the deck. High tensile tie straps (27a, 27b) are held between the vertical webs of the angles (23) by pins (69). A tubular pedestal (25) has upper recesses (49) which mate with a box beam supporting the seats. Threaded studs (73)of the tie straps (27a, 27b) are bolted to the box beam so that inertial forces arising in the event of an impact of the craft will be uniformly distributed by the pedestal, tie straps (27a, 27b), and angles (23), to the track for dissipation over an extended length of track, thus reducing the effects of localized shear. On assembly of the system, the angles (23) need not to be slid along the track but may be inserted individually being later spaced apart by insertion of tie straps (27a, 27b) so as to laterally the cavity (35).
