    • In order to prevent theft of a vehicle, the front seat is movable into a position where it impedes access to the vehicle controls and only once it has reached that position is locked in place. Two methods of locking the seat are disclosed. The first method (Figure 3) comprises a lever 21, turnable by lock barrel 22, which is coupled to one or both of bolts 23 and 24. Tilting seat back 11 forward relative to squab 12 causes rotation of cam 28 into a position where bolt 23 may be displaced upwards to lock the seat back. Similarly alignment of the seat squab with a recess (30) in the seat track 15, enables bolt 24 to be displaced downwards into the recess. Thus once the seat has been moved into the required position, rotation of barrel 22 serves to simultaneously lock the seat squab to the track and lock the seat back in its forward tilted position. In the second method (Figure 9), the seat back is first tilted forward, aligning recess 121 with channel 27. Ramp 140 is fixed to the seat track and displaces spring loaded bolt 124 upwards and into engagement with recess 121 as the seat is moved forward along the track. Locking of the seat squab to the track is achieved once the bolt is urged into detent 142 under the action of the spring. To unlock the seat again, cam 144 is rotated, lowering the ramp allowing bolt 124 to be released from the detent.
