The seat cushion (2) is of width (b), and hinges (A) at a distance(s) from the cab rear wall (3) equal to its thickness. The back cushion (4) is of width (a) and thickness equal to (s), and hinges (B) on the rear wall, being normally at an angle (a) to the latter. The value of b is equal to a + s, and the relationship between angle a, distance s and width a is determined by the formula:- Sin alpha = s/a = between 0.19 and 0.25.% USE/ADVANTAGE - Easy access to storage box in vehicle cab without complicated mechanism.
