Seat 2 is mounted to slide blocks 24 and rails 22 , which in turn are mounted to upstanding brackets 20 . The fore-and-aft adjustment of the seats is thus raised above the level of floor 16 , avoiding fouling by sand and dirt; corrosion; and shorting where electric seat adjustment is used. Seat 2 comprises frame 4 , backrest 14 , and tip-up seat 8 which can be raised around pivots 6, 6 ' to allow a higher seating position for marine use. In marine mode, the helmsman sits on cushion 10 ; in road mode, the driver sits on cushion 12 . Latches are provided for fore-and-aft and tip-up cushion adjustment. Flaps 26 may protect sliding surfaces from contamination. Rails 22 may face upwards ( 34 , FIG. 3 ), downwards ( 44 , FIG. 4 ), or sideways, as convenient; the seat may be supported on a cradle ( 40 , FIG. 4 ). Slide blocks may be replaced by rollers ( 32 , FIGS. 2, 6 ).
