A vehicle seat frame 1 is pivotally connected at 14, at the rear on each side, to a support member 12 angularly moveable about a floor anchorage 13 and the members 1, 12 are selectively connected at one of a number of different points spaced from the connection 14 to hold the seat in the required position. In the form shown the selective connection is by a removable pin 15, on an arm integral with the member 12, and a series of holes in a quadrant 4 integral with the frame 1; the seat is mounted at the front on links 2. The strengthening members 18, 19 may be omitted. A seat back frame 6 of @ form is pivoted to the frame 1 at 8 and has integral with it struts 7 connected to the frame 1 at their lower ends by pins 9 selectively engaging holes 10 in lugs 11 on the frame; removal of the pins 9 allows the back 6 to be folded forwards on to the seat or backwards to a reclining position. The pivot pin 8 may serve as attachment for a seat belt 17, the pull of which is transmitted more or less directly to the anchorage 13. The seat back is strong enough to provide anchorage for a shoulder strap. In a modification, Fig. 6 (not shown), the members 1, 4, 18, 19 are parts of a unitary flanged sheet metal pressing (21), and the rear support 12 is replaced by a triangular member (24) carrying the pin 15 (28); the link 2 is replaced by a post (22) fixed to the floor and carrying a pin slidably engaging a horizontal slot in the seat frame. The pins (28) setting the position of the seat may be actuated by power. The seat back (31) is rigid with an arm (32) pivoted to the rear end of the seat frame, and the back strut (30) is pivoted at the same point, so that the back and strut form a rigid unit; this is held in adjusted position by teeth on the front end of the arm (32) engaged by a rack (34) slidable against spring pressure into engagement with the former teeth by a lever-operated cam (35). In this form the seat belt is attached to the seat frame (21) at a suitable point (39).
