Description

[Detailed Description of the Invention] The present invention relates to a trunk-through lock device that locks the forward-folding of the so-called trunk-through type rear seat back seat that can be folded forward, which separates the trunk of a vehicle from the passenger compartment. be.

Conventionally, a request key used when requesting someone else to transport a car can usually be used to unlock the door and start the engine, but has a structure that cannot unlock the interior dash pocket or trunk room. However, trunk-through type cars, which have rear seats that can be folded forward or a part of the center of the back seat that can be folded forward to open the interior and trunk area, allow you to freely take out and take out luggage from the interior of the vehicle. When allowing someone else to use the vehicle, a problem has arisen in which the trunk compartment cannot be locked.

This invention was developed to solve the above-mentioned drawbacks, and when the car owner uses the car normally, the back seat can be folded forward and opened and closed freely. To provide a trunk-through lock device which locks the reclining of a back seat using a main key owned by a person and cannot release the lock with a requested key entrusted to another person.

Hereinafter, embodiments of the trunk-through lock device of the present invention will be described with reference to the drawings. 1 is a rear seat that separates the trunk room and the passenger compartment of an automobile, and a separate back center 3 is embedded in a part of the back seat 2 that is hollowed out and rotatably pivoted to both ends of the back center via hinges 4. It consists of The back center 3 is housed in close contact with the inner periphery 7 of the back seat 2, and a locking bar 5 is installed and screwed into a recess provided on the top surface of the back seat 2, and a base wire 8 is formed as a framework within the back seat 2. The hook 9, which is rotatably pivotally attached to the hook 9, elastically urges the locking bar 5 in the locking direction by means of a spring member or the like (not shown), thereby fixing the center back portion 3. Reference numeral 10 denotes a lock part for operating the hook 9 which is fixed at a suitable position in the car so that it can be operated from the driver's seat, and locks the handle 12 and the wire end 14 of the control cable 13 onto the L-shaped bracket 11 which serves as a board. A lever 16 constituted by a locking piece 15 is rotatably attached to a pin 17 implanted in the bracket 11. Reference numeral 18 denotes a cylinder lock provided to lock the movement of the lever 16, and a tongue piece 19 protrudes to the side at the lower end only when the main key normally owned by the car owner is operated.
rotates, and the tongue piece 19 moves the side of the lever 16.
The lever 16 is fixed in contact with the lever 16 to prevent movement of the lever 16.

The aforementioned lock part 10 has a wire terminal 20 which is inserted into a hook 9 that hooks the back center 3 via a control cable 13 which is disposed on the underside of the interior carpet and fixed to a fixed end 20 in the back seat. When the lever 16 of the lock portion 10 is operated, the locking piece 15 tensions the wire 22 and the other end 21 is connected to the hook 9.
It comes to raise the level.

In the trunk-through lock device having the above structure, when the cylinder lock 18 of the lock portion 10 is released (position shown by the dotted line in Figure 3), the lever 16 is attached to the pin 1 of the fulcrum.
The handle 1 of the lever 16 is rotatable around the axis 7.
When the wire 2 is pulled up, the locking piece 15 at the working end
2, and this tension causes the end 21 of the hook side wire to pull up the hook 9 hooked to the locking bar 5 installed on the center back 3, and the hook 9 on the center back 3 is pulled up. Since the fixation caused by

In addition, when the cylinder lock 18 is locked by the main key (solid line position in Figure 3), the lever 1
6 is fixed by the tongue piece 19 and the handle 12 cannot be pulled up, so the locking bar 5 on the back center 3 is kept in the state where the hook 9 is hooked, and the back center 3 is fixed. It cannot be canceled. Furthermore, the request key cannot be inserted into the cylinder lock,
Furthermore, even if the tongue piece 19 can be inserted, the lock part 10 cannot be released because the tongue piece 19 is structured not to rotate.

As explained above, the trunk through lock device of the present invention allows you to easily release the locking mechanism of the back seat or the forward-folding part in the center of the back by operating the lever of the lock part located at the closest position in the car, and also allows you to easily release the locking mechanism of the back seat or the forward-folding part in the center of the back. When using a car, the main key can be used to lock the car from tipping forward, making it impossible to take out luggage in the trunk.
The practical effects after implementing this invention are extremely large.
