A lock is provided for a vehicle having a door and a fixed part proximate the door. The lock includes a housing attached to the vehicle door. Latch means, including a hook, are mounted for rotation relative to the housing about an axis. The latch means rotates between a first position, wherein the hook engages a part of the vehicle to secure the door in the closed position, and a second position, wherein the hook is remote from the vehicle part such that the door can be opened. A latch rotation preventing member is moveable, relative to the housing, in a direction substantially parallel to the axis of rotation of the latch, between a forward position, remote from the path of movement of the latch means and a rear position, intersecting the path of the latch means to retain the latch means in its first position. Means are also provided for biasing the member toward the rear position.

I claim: 1. A lock for a vehicle having a door having an exterior surface and a fixed part proximate the door, the lock comprising a housing with a front wall and a rear wall, attached to the vehicle door with said rear wall proximate said exterior surface of said door; latch means comprising a hook, said latch means being mounted in said housing, for rotational movement about an axis, between a first rotational position, wherein said hook engages the part to secure the door in the closed position and a second rotational position wherein said hook is remote from the part such that the door can be opened; a latch rotation preventing member linearly moveable relative to said housing, in a direction substantially parallel to said axis of rotation of said latch means, between a position spaced from said rear wall of said housing, remote from the path of movement of said latch means and a position proximate to said rear wall of said housing, intersecting the path of said latch means, to retain said latch means in its said first rotational position; and means for biasing said member toward said position proximate said rear wall of said housing, further comprising means for locking said member in said position proximate said rear wall of said housing, wherein said locking means comprises a key actuated lock cylinder mounted for movement between a locked position and an unlocked position, and wherein said locking means further comprises a linkage part connected for movement with said lock cylinder and comprising a cam surface, where said locking means is axillary offset from said latch rotation preventing member. 2. The lock of claim 1 further comprising a cam on said member, in engagement with said cam surface. 3. The lock of claim 2 wherein said cam surface comprises the rim of said linkage part. 4. The lock of claim 3 wherein said linkage part comprises an axis and wherein said rim of said linkage part lies in a plane that is inclined relative to said linkage part axis. 5. The lock of claim 1 wherein said linkage part comprises a recess into which said lock cylinder is at least partially received. 6. The lock of claim 1 further comprising a handle accessible from the exterior of the housing and connected to rotate said latch means. 7. The lock of claim 1 further comprising spring means connected between said latch means and said housing. 8. A lock for a vehicle having a door and a fixed part proximate the door, the lock comprising a housing attached to the vehicle door and having a front and a rear; latch means comprising a section, mounted within said housing and rotatable about an axis extending between the front and rear of said housing, and a hook; a handle accessible from the said front of said housing and connected to rotate said section along a path between a first position, wherein said hook engages the part to secure the vehicle door in the closed position and a second position, wherein the hook is remote from the part such that the door can be opened; a key actuated lock cylinder mounted in said housing for movement between a locked position and an unlocked position; a member, operatively connected to said cylinder, linearly moveable relative to said housing in a direction substantially parallel to said axis about which said section rotates, between a position spaced from said rear of said housing, remote from said path, and a position proximate said rear of said housing, intersecting said path, as said cylinder moves between said unlocked position and said locked position, and means for biasing said member toward said position proximate said rear of said housing, wherein said key actuated lock cylinder is axillary offset from said member, further comprising means operatively connecting said cylinder and said member; wherein said connecting means comprises a linkage part connected for movement with said lock cylinder, a cam surface on said linkage part and a cam associated with said member, in operative engagement with said cam surface. 9. The lock of claim 8 wherein said linkage part is rotatable about an axis and wherein said cam surface is situated in a plane inclined relative to said linkage part axis. 10. The lock of claim 9 wherein said linkage part has a recess into which said lock cylinder is at least partially received. 11. The lock of claim 9 wherein said axis of said linkage part is substantially parallel to said axis about which said section rotates. 12. The lock of claim 8 wherein said cam comprises a protrusion extending from said member. 13. The lock of claim 12 wherein said member has an axis and wherein said protrusion extends in a direction generally perpendicular to said axis of said member. 14. The lock of claim 8 further comprising spring means operatively connected between said housing and said latch means.
