A detachable van supporting arrangement is disclosed which allows a seat structure to tip into a forward direction and also allows an individual to easily remove the seat from the vehicle without the use of tools. The locking mechanism uses two slots in a base plate communicating with two rods in a tube plate to lock the seat into a secure position. The first rod is inserted in a U-shaped slot with a detention at a bottom portion which provides a pivot point. The U-shaped slot allows the seat to be easily removable from the vehicle by lifting the rod out of the slot. The second rod associates with a L-shaped slot. The first and second rods are connected by links. An over-center locking mechanism moves the rods within the designated slots. The second rod includes a handle. Rotation of the handle moves the two rods against stop means and continued rotation cause the over-center locking mechanism to move beyond the point of eccentricity and provide a snap lock.
