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).
An amphibious vehicle having a seat frame structured to support a seat, the frame being adjustable in a fore and aft direction relative to a floor by means of an adjustment arrangement, the arrangement comprising at least a first part and a second part, the first part mounted fixedly to the seat frame and the second part co-operating with the first part and mounted fixedly with relation to and above the floor and not below the seat frame, wherein the seat frame has a tip-up seat pivotally mounted thereto so as to provide two levels of seating, and wherein the ratio of the width between the seat mountings to the height from the driver's seat cushion to the centre level of the seat mounting track is between 1.50 and 2.40 with the seat in its upper, or marine, position.
