     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     In motor vehicles of the type having a drivers seat, a passenger seat adjacent the drivers seat and a luggage compartment 10 disposed rearward of the seats, it is often desirable to have a means for enclosing and locking valuables stored in the luggage compartment. It is also often desired to carry passengers such as small children in the luggage compartment, and a seat for the extra passengers comfort is needed. The storage compartment and seat of the present invention is designed to accomplish these desired objectives in a vehicle such as the Mercedes Benz two seat roadster. 
     As shown in FIGS. 1, 2 and 4, the storage compartment and seat 12 of the present invention comprises a compartment formed by a vertical front wall 14 disposed a distance rearward of a rear edge of the seats to provide leg room; an opening extending upward from a lower edge thereof to clear a drive shaft tunnel, with the front wall 14 extending transversely across the luggage compartment; a rear wall 16 adjacent a rear wall of the luggage compartment disposed parallel to the front wall, and extending transversely across the luggage compartment. A pair of opposed end walls 18, 20 extend between the front and rear walls to form an enclosed boxlike structure with an open top. An outer surface 22 of the end walls has an irregular shape which conforms to the luggage compartment side wall, and an inner surface 24 of the end walls is spaced inward of the outer surface and extends perpendicularly between the front and rear walls with a top edge flush with a top edge of the front wall. A pair of opposed projections 26, 28 extend above the top edge of the inner surface and spaced outward a distance therefrom to form a ledge 30 along the top edge of the inner surface. The projections 26, 28 extend between the front and the rear walls 14 and 16. Tracks 32 are formed along an inner edge of the projections and extend from the front wall to the rear wall. The function of the tracks 32 will be explained more fully hereinbelow. A pair of opposed top walls 34, 36 extend from the inner surface to the outer surface and from the front wall to the rear wall to enclose an end portion of the compartment 12. A bottom wall 38 extends between the lower edges of the outer surfaces and from a lower edge of the front wall to a lower edge of the rear wall along the vehicle floor. The bottom wall 38 conforms to the contour of the vehicle floor to enclose the storage compartment bottom. 
     One or more hollow compartment dividers 40 extend between the front and rear walls perpendicular thereto. A compartment divider top wall 42 extends between sides of the compartment divider 40 and is positioned flush with the top edge of the front wall providing support for a seat panel when it is in a first position as will be described more fully hereinbelow. 
     As shown in FIG. 1, and in greater detail in FIGS. 5, 6 and 7, the storage compartment seat 44 comprises a pair of panels 46, 48 joined together by a first hinge 50. The panels are movable from a first position wherein the panels extend from the front wall to the rear wall and between projections enclosing the compartment 12 forming a seat of planar configuration, to a second position wherein the panels are hinged together opening the compartment. A second hinge 52 hinges a rear edge of the panel to a top edge of the rear wall. A pair of opposed rods 54 project transversely from a forward edge of the panel 48 to engage the tracks 32, the rods are slidable along the tracks 32. 
     A torsion spring 66 next to the first hinge 50 biases the panels to the second position. 
     A lock means 60 is provided for locking the panels in the first position. The lock means includes a downward extending hinged lock bar 62 hinged to a panel and biased to engage a latch when the panels are moved to the first position. The lock bar 62 hinges against a bias means 58 to clear the adjacent panel 46 when the seat is moved to the second position and the panels are folded together as shown in FIG. 7. 
     As shown in FIG. 3, the lock means 60 comprises a lock housing 68 disposed between the sides of the hollow compartment divider 40 and a latch 64 supported by the housing and movable therewithin between a first position holding the lock bar 62 in a first position to a second position releasing the lock bar 62 and allowing the seat to be moved to the second position. An opening 70 is formed in the divider top wall which is configured to receive the downward extending lock bar 62. A lock housing opening 82 allows the lock bar 62 to reach the latch 64. The latch 64 is positioned to engage the lock bar 62 when it is moved to the first position. An opening 63, FIG. 6, formed in the lock bar is configured to releasably engage the latch. The latch 64 is biased to the first position by means of a spring 74 with one end of the spring abutting the housing and another end of the spring abutting the latch. The latch 64 is movable within the housing 68 by either the lock bar abutting and sliding against a ram 76 along the latch, or by a push button 78 projecting through an opening formed in the front wall 14. The push button 78 when depressed urges the latch 64 against the spring 74 by means of an actuator rod 80 extending between the push button 78 and the latch 64. When the push button 78 is depressed the latch releases the lock bar 62 allowing the seat to be moved to the second position. The pair of opposed rods 54 are slid rearward along the tracks 32 to move the seat to the second open position. 
     To move the seat from the second or opened position to the first or closed position the forward edge 56 of the panel is urged forward, the rods 54 slide in the tracks 32, and as the seat approaches the first position the lock bar 62 enters the opening 70 and the opening 82. A forward edge of the lock bar 62 abuts a forward edge of the opening 82, and as the seat is latched to the first position the lock bar 62 moves along the ramp 76 urging the latch 64 against the spring 74. The opening 63 in the lock bar 62 engages the latch 64 latching the seat in the first position. When in the first position the panel 46, 48 rest on the ledge 30 and the compartment divider top wall 42 and a pair of brackets 84 affixed to the inner surfaces 24. The brackets 84 have a horizontal surface flush with the ledge 30 to aid in the support of the panels in the first position. 
     A key receiving opening 86 in the push button 78 is configured to receive a key 88 which rotates the push button 78 from a first position wherein the push button is depressable to release the latch to a second position wherein the push button 78 is locked against movement. The push button 78, the opening 86, and the key 88 cooperate to define a key rotatable lockable push button which in a first position is depressable to release the latch from engagement with the lock bar, and in a second position when the key is rotated the push button is locked against movement. 
     There has been described hereinabove a lockable storage compartment and seat with a form which complies with the luggage compartment disposed behind the seats of a two seated vehicle. The lockable storage compartment includes a cover movable from a closed position wherein the compartment is locked and the cover serves as a seat, to an open position wherein access to the storage compartment is provided. The cover serves as a seat for seating additional passengers as well as a means for enclosing and locking the storage compartment.
