Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a locking device for a rear seat bag in an automobile in which a passenger compartment and a trunk space are separated by a foldable rear seat bag.

[Prior Art] As a locking device for a rear seat back of an automobile in which the passenger compartment and trunk space are separated by a foldable rear seat back, there is a structure as disclosed in Japanese Utility Model Application Publication No. 58-73040. Are known.

The locking devices disclosed in these publications are equipped with a security mechanism that prevents the rear seat back from being unlocked from inside the vehicle by combining it with a cylinder lock or with an unlocking inhibiting means operated from inside the trunk. ing.

However, in the lock devices disclosed in these publications, the lock mechanism operated by a rotating handle and the safety mechanism are made into a single assembled structure.
Due to the arrangement of the rotating handle, the mounting location is limited, and it is not impossible to insert a wire etc. from around the rotating handle to move the security mechanism to a non-operating position. There is a problem above.

[Problems to be solved by the invention] In view of the current state of the conventional locking device described above, the present invention increases the degree of freedom in designing the rear seat locking device and eliminates the possibility of making it inactive with a wire or the like. The object of the present invention is to provide a rear seat locking device that is extremely small in size and has a sufficient security function.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a lock for fixing the rear seat bag in an upright position in an automobile in which a passenger compartment and a trunk space are separated by a foldable rear seat bag. The mechanism is connected via a connecting rod to a lock cancel mechanism operated by a release button, and the lock cancel mechanism is connected to a release lever connected to the release button and to the lock mechanism via a connecting rod. The release lever and the lock lever are connected by a connecting pin, and the connecting pin selectively moves between two positions: an active position where the release lever and the lock lever are connected, and a non-active position where the release lever and the lock lever are not interlocked. The operating section of the connecting pin operating mechanism is arranged so as to face only the interior of the trunk.

[Function] In the present invention, the lock mechanism is connected to the lock cancel mechanism via the connecting rod, and the mounting positions of the lock mechanism and the lock cancel mechanism can be separated from each other. The degree of freedom in design regarding structure and arrangement is increased, and it is difficult to unexpectedly turn the lock cancel mechanism into a non-operating state by external operation such as insertion of a wire, thereby improving the crime prevention effect.

The lock cancel mechanism also includes a lock lever connected to the lock mechanism by a connecting rod and a release lever connected to a release button, and a connecting pin connecting both levers can be moved between an operating position where both levers are interlocked and a non-interlocking position. By selectively moving the release lever between two positions, the locking mechanism can be locked and unlocked by operating the release lever, and the locking mechanism can also be put into a lock cancel state, making the mechanism relatively simple.

In addition, since the operating part of the lock cancel mechanism is located facing only into the trunk, the lock mechanism is in the locked state and the lock cancel mechanism is operated from inside the trunk to unlock the connecting pin. If the trunk lid is moved to the active position and the trunk lid is locked, the rear seat bag will not be folded down even if the release button is operated from inside the vehicle, and crime prevention in the trunk room will be achieved.

Further, according to the present invention, the lock mechanism is operated by the lock lever in the lock cancel mechanism, so that the release button can operate the lock lever by simply pushing and pulling the release button.
Therefore, the gap around the release button can be made smaller, and insertion of wires and the like can also be prevented in this respect, thereby improving security.
