Abstract: 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).
