JPS6157436A - Car rear seat back - Google Patents

Abstract

PURPOSE:To allow a device to be burglarproof in the trunk-through type car by configurating the device in such a manner that a rear seat back can not be folded forware from the cabin side without unlocking a lock mechanism with a trunk room lid opened. CONSTITUTION:No.1 operating knob 19 of No.1 unlocking unit 21 is pulled upward while No.3 unlocking unit 34 is in a condition of unlocking. This allows a pin 15 engaged with a long hole 16 of No.1 hook to be lifted up through No.1 hook 17 causing a latch in a lock base 9 to be swung through both a ring plate 14 and a shaft 10. This enables a striker to be pulled out from the lock base 9 allowing a seat back to be folded forward. On the other hand, the movement of an operating knob 45 to No.3 unlocking unit 34 to a lock section 46 causes No.3 hook to be pulled down through both a lock pin 43 and an inner wire 33a. This prevents the pin 15, which is engaged with a long hole 30 of a hook 31, from being pulled upward keeping the striker staying in the locked position.

Description

[Detailed Description of the Invention] a. Field of Industrial Application This invention relates to a rear seat back for an automobile, and in particular, a rear seat back for an automobile, which is called a trunk-through system, is folded forward to communicate with a passenger room and a trunk room. This invention relates to a locking device for a rear seat back.

b, UP: Next technology As such a conventional locking device, for example, Jkkaisho J-≦-
77" As shown in Publication No. 39, the passenger room is equipped with a first unlocking operation part of a locking machine that can engage and detach the seatback from the vehicle body, and the lid of the trunk compartment can be opened to remotely control the locking mechanism. Some vehicles are provided with a second unlocking operation section inside the trunk that can be unlocked by the following steps.

Problems to be Solved by the C0 Invention However, with such a locking device, it is not possible to use the trunk room as a storage space.

In other words, when the door is left unlocked and left unattended, or when the door lock is broken and the passenger enters the passenger compartment, if the first unlocking operation section is operated, the locking mechanism will be unlocked and the vehicle body will be unlocked. The seatback can be engaged and detached from the trunk, the seatback can be moved forward, the trunk room and the bassenger room are communicated with each other, and the luggage in the trunk room can be easily taken out.

In view of the drawbacks of the conventional example, the present invention has been developed to open the trunk lid and lock the rear seat back.
The purpose is to make it impossible to fold the rear seat back forward from the passenger room side without unlocking the '4.

d1 Means for Solving Problems In order to achieve this purpose, a seat back is provided with respect to the vehicle body so that it can freely tilt forward from an upright position, and is locked by a locking device in the upright position. In an automobile rear seat back configured to be held in a stopped state, the locking device is rotatably supported by a shaft with respect to the vehicle body, and includes a striker provided on the back surface of the seat back.
a latch that can be freely engaged and detached from the shaft; a link grate having one end fixed to the end of the shaft and a pin protruding from the other end; and a lower elongated hole engaging the pin at the lower end. a rond-shaped first unlocking member having a first hook and a first operation knob protruding from the upper part of the seat back toward the bassenger room at its upper end;
a grate-shaped second unlocking member having a second locking hook in which the pin is engaged with the long hole below the road at one end, and a λ-th unlocking knob protruding toward the trunk room at the other end; has a third hook in which a long hole below the road is engaged with the pin;
The other end has a lock release means provided near the trunk opening, and the two are connected by a flexible wire.
It is composed of an unlocking member.

e0 Effect of the invention (Since it consists of 8 components, when the unlocking means of the third unlocking member is set to the lock side and the lid on the trunk side is locked, the elongated hole of the third hook moves and the upper end of the hole is in pressure contact with the pin and prevents the pin from moving.
Even if you try to move the first unlocking member while in the bassenger compartment, the pin will not move, so it will remain in the locked position and the seatback will not be able to be folded forward, leaving the luggage compartment in the trunk safe. . Moreover, if the lid on the trunk side is opened, the second and third unlocking members can be operated, so first set the unlocking means of the third unlocking member to the lock-off side, and then set the second unlocking member to the lock-off side. When you press the S2 unlocking knob on the member, the long hole in the M<2 hook moves, pushing the pin up and rotating the latch via the link lever, allowing the seat back striker to be released. Example Next, a persimmon example of the present invention will be explained with reference to FIG. 1 and the following drawings.

First, the configuration will be explained. In the figure, / is the rear seat, which is supported by a seat cushion fixed to the floor panel (not shown) and a place 3, which is the vehicle body in which a trunk through opening log is formed, and is provided so that it can freely tilt forward from an upright position. bank! ,!

No matter which one of 31 is moved, the other two hooks do not move.

g0 Effects of the Invention As described above, according to the present invention, if the third unlocking member is locked and the trunk opening is closed, even if the first unlocking member is operated from the bassenger room side to lock off. It does not lock off, the seat back cannot be folded forward, and even if it is a trunk-through type, it is impossible to open the trunk room from the passenger room side. Therefore, even if the door is locked off, there is no risk of burglary.
