A locking device for a foldable backrest of a seat, has a locking housing with a handle, the handle being pivotably between locking and unlocking positions and by which a pawl can be carried between retaining and non-retaining positions, and has a blocking element which is movable by a closable lock
A locking device for a foldable backrest of a seat, has a locking housing with a handle, the handle being pivotably between locking and unlocking positions and by which a pawl can be carried between retaining and non-retaining positions, and has a blocking element which is movable by a closable lock manually between a blocking position blocking the handle and a release position releasing the handle. The blocking element is a locking bolt mounted pivotably in the locking housing between the blocking and release positions and having release and blocking recesses. A blocking pin, in the release position of the locking bolt, projects into the release recess and is freely movable between the locking and unlocking positions. The blocking pin, in the blocking position of the locking bolt and the locking position of the handle, protrudes into the blocking recess and is blocked against pivoting into the unlocking position.

1. A locking device for a foldable backrest of a seat, comprising: a locking housing in which there is arranged a handle which can be pivoted about a pivot axis between a locking position and an unlocking position and by which a locking detent can be carried between a locking position and an unlocking position;a blocking element which can be moved by a closable lock manually between a blocking position which blocks the handle in the locking position thereof and a release position which releases the handle,wherein the blocking element is a closure bar which is supported in the locking housing so as to be able to be pivoted about a bar axis between the blocking position and the release position and which has a release recess and a blocking recess, andwherein the handle has a blocking pin which, in the release position of the closure bar, protrudes into the release recess and can be freely moved in the release recess by the handle being pivoted between the locking position and the unlocking position, and which, in the blocking position of the closure bar and the locking position of the handle, protrudes into the blocking recess and is blocked against pivoting into the unlocking position,wherein the closure bar has a spring catch which can be moved from an assembly position protruding radially from the closure bar counter to a resilient force into a radially non-protruding position for use and which, in the assembly position thereof, protrudes with the radially protruding free end thereof into a catch groove of the locking housing that is parallel with the bar axis. 2. The locking device as claimed in claim 1, wherein the bar axis extends transversely relative to the pivot axis of the handle. 3. The locking device as claimed in claim 2, wherein the closure bar which is secured against axial displacement has a release groove which extends parallel with the bar axis, which forms the release recess and which in the release position of the closure bar faces the handle and into which the blocking pin protrudes, an end of the release groove opening in an at least partially radially peripheral blocking groove which forms the blocking recess and one side wall of which forms a blocking stop which the blocking pin can abut so as to block a movement of the handle from the locking position into the unlocking position. 4. The locking device as claimed in claim 3, wherein the closure bar has a radially protruding securing attachment which, when the closure bar is in the blocking position, is in abutment axially relative to the bar axis with at least one securing stop which is secured to the housing so as to support a force which is applied to the closure bar by the blocking pin which is acted on by the handle in the unlocking position. 5. The locking device as claimed in claim 1, wherein the closure bar can be pivotably driven by a key-actuatable closure cylinder between the release position and the blocking position. 6. The locking device as claimed in claim 1, wherein the closure bar is resiliently loaded into the release position thereof by a pretensioned spring. 7. The locking device as claimed in claim 1, wherein the spring catch is a resilient arm which is fixedly arranged with one end thereof on the closure bar, which protrudes freely in a radial manner and which in the relaxed assembly position thereof protrudes radially from the closure bar with the other end thereof and can be redirected by application of axial force from the radial assembly position into the position for use thereof, in which it extends in a manner inclined relative to the bar axis through an angle which differs from 90°. 8. The locking device as claimed in claim 5, wherein the closure cylinder has a closure pin which protrudes parallel with the rotation axis of the closure cylinder, and which engages in a corresponding closure recess at the end face of the closure bar facing the closure cylinder, and in that a resilient arm is acted on by the free end of the closure pin of the closure cylinder which is located in its assembly position in the locking housing so as to be deflected into the position for use thereof. 9. The locking device as claimed in claim 1, wherein the backrest is configured to form a partition wall between a passenger space and a luggage space of the motor vehicle.
