1. A lock for a motor vehicle comprising:
- a locking mechanism comprising a rotatably mounted rotary catch for receiving a locking bolt, and a pawl with which the rotary catch can be engaged for retaining the locking bolt,a blocking lever that blocks the pawl when the pawl is located in a main catching position, wherein the blocking lever blocks the pawl by a surface of the blocking lever contacting a surface of the pawl,a releasing lever for placing the locking mechanism in a disengaged state, anda first spring that interconnects the blocking lever and the releasing lever,wherein the blocking lever and the releasing lever move together in response to a first acceleration of the releasing lever, and the releasing lever moves independently relative to the blocking lever in response to a second acceleration of the releasing lever, wherein a magnitude of the second acceleration is greater than a magnitude of the first acceleration;
and a second spring which moves the blocking lever into a blocking position in which the blocking lever blocks the pawl in the main catching position.

Abstract
A lock for a motor vehicle includes a locking mechanism with a rotatably mounted rotary catch for receiving a locking bolt, and a pawl with which the rotary catch can be engaged for retaining the locking bolt. The lock further includes a blocking lever that blocks the pawl when the pawl is located in a catching position, and a releasing lever for disengaging the locking mechanism. A first spring interconnects the blocking lever and the releasing lever, wherein the blocking lever and the releasing lever move either together or independently relative to the first spring based on a magnitude of acceleration of the releasing lever.

13. A lock for a motor vehicle comprising:
-
a locking mechanism comprising a rotatably mounted rotary catch for receiving a locking bolt, and a pawl with which the rotary catch can be engaged for retaining the locking bolt; wherein the rotary catch is rotatable between a main catching position and a preliminary catching position, and the pawl engages the rotary catch in the main catching position and the preliminary catching position; a blocking lever that blocks the pawl when the rotary catch is located in the main catching position and in the preliminary catching position, and a releasing lever for causing the pawl to move out of engagement with the rotary catch in the main catching position and the preliminary catching position such that the locking mechanism is placed in a disengaged state, wherein the rotary catch introduces an opening moment onto the pawl when the pawl is in the main catching position and the preliminary catching position; wherein the blocking lever comprises a tongue which enters a dent formed in the rotary catch in the preliminary catching position. - View Dependent Claims (14)
