Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in a rear seat of an automobile in which a backrest is installed so that it can be moved forward.

(Prior art) The backrest of the rear seat of a car is installed so that it can be moved forward, and by moving this backrest forward, the structure for communicating with the luggage space, such as the luggage compartment or luggage room, which is formed behind the rear seat, has already been developed. It is known and one example of this conventional structure is, for example,
As shown in FIG. 4 and the structure disclosed in Japanese Utility Model Laid-Open No. 62-105855, a head-rest b mounted on the top of the backrest a of the rear seat has a pull-up operation knob c on the side thereof.
Alternatively, by arranging a push (or slide) operation knob d and operating (pulling up, pushing or sliding operation) the operation knob, the holding lock mechanism built in the backrest a is released, and the backrest a is opened. The structure is used to move it forward by hand.

(Problem to be Solved by the Invention) In the above-mentioned conventional structure, the operation knob is attached in a position avoiding the headrest in a state of being juxtaposed with the headrest, and the knob is detached and protruded from the top of the headrest. Therefore, the backrest top side is close to the rear pillar due to the problem that it lacks a sense of unity with the backrest, impairs the appearance form, and the necessity of avoiding the mounting position of the headrest because of the mounting position of the operation knob. , There is a problem that the rear pillar interferes with the operation of the operation knob and its operability is not good, and solving these problems,
This is the problem to be solved by this invention.

(Means for Solving the Problem) As a means for solving the above problems, the present invention has a structure in which a gate-type headrest having a pair of supporting legs is attached to the top of a backrest, and the top of the backrest straddled by the pair of supporting legs is The gist of the present invention is that the holding lock mechanism of the backrest that is built in the backrest is released in the middle, and an operation knob that can be moved forward is arranged.

(Operation of the Invention) In this invention, the headrest has a gate structure, and an intermediate space secured by this gate structure acts as an access space for the operation knob, and a backrest surrounding the operation knob with the headrest is provided. Attached to the top part, this gives the operation knob a sense of unity with the backrest, makes its presence unnoticeable, and improves the appearance of the backrest in combination with the open feeling due to the gate type backrest,
The operation knob is also located at the center of the top of the backrest, so that the operability is improved.

(Embodiment) The present invention will be described in detail with reference to an embodiment shown in FIGS. 1 to 3 in which the invention is applied to an automobile having a luggage compartment. The backrest 2 of the rear seat 1 is provided at the boundary with the luggage compartment 3. The striker 6 mounted on the rear bulk 4 has the claw 51 of the holding lock mechanism 5 which is arranged along the rear bulk 4 and is built in the backrest 2.
And is held in an upright state along the rear vehicle body structure portion W including the rear pillar and the rear quarter as shown in FIG.

As a mechanism for releasing the holding lock mechanism 5 for holding the backrest 2 in the upright state to shift the backrest 2 from the upright state to the forward position, as shown in FIGS. And a link mechanism 8 connected thereto is provided, and the holding lock mechanism 5 is released by operating these mechanisms. The operation knob 7 is a push-type operation mechanism provided in a recess 23 formed in an intermediate portion 22 straddled by a pair of left and right supporting legs 91, 91 of the gate-type headrest 9 attached to the center of the top portion 21 of the backrest 2. The operation knob 7 operates the holding lock mechanism 5 via the link mechanism 8 to release the locking relationship between the striker 6 and the backrest, so that the backrest 2 can be moved forward. The phosphorus mechanism 8 is a first mechanism that transmits the force generated by pushing down the operation knob 7.
Link 81, second link 82, connecting rod for connecting these
83, a connecting pipe 84 for transmitting the operating force of the second link to the holding lock mechanism 5, and the first link 81 is directly connected to the operation knob 7. The holding lock mechanism 5, to which the second link 82 is connected via the connecting pipe 84, acts on the claw 51, which is locked to the striker 6, and the claw 51.
A return spring 52 for urging the claw 51 in a direction to release the claw 51, a sub claw 53 for engaging the claw 51 to lock the claw on the striker 6, and a claw 53 for acting on the sub claw 53. And a return spring 54 for urging the engagement of 51, the claw 51,
The return spring 52 is pivotally supported by the casing of the holding lock mechanism 5 so that the return spring 52 has a rotation center, and the connection pipe 84 is pivotally attached to the rotation center of the sub-claw 53, and the return spring 54 is suspended on this.

To release the holding lock mechanism 5 described above, the operation knob 7 arranged between the supporting legs 91, 91 of the gate-type headrest 9 may be pushed down (direction of arrow A1 in FIG. 2), and the operation knob 7 pushed down. Force pushes the second link 82 in the direction of arrow A2 via the first link 81 and the connecting rod 83, whereby the second link 82 rotates in the direction of arrow A3, and this rotating force causes the connecting pipe 84 to move. It is transmitted to the sub-claw 53 of the holding and locking mechanism 5 through the sub-claw 53 to rotate the sub-claw in the direction of arrow A4 in FIG. The sub claw 53 rotates counterclockwise against the bias of the return spring 54, and by this rotation,
The sub claw 53 and the claw 51 are disengaged, and the claw 51
Is rotated by the return spring 52 in the direction of arrow A5, and this rotation causes the claw 51 to disengage from the striker 6, the holding lock mechanism 5 to be released, and the backrest 2 to be able to be tilted forward. The state of communicating with the luggage space can be secured. When the backrest 2 that has been moved forward is restored to the original standing state, the backrest 2 may be raised as it is, and the striker 6 pushes the lower part of the claw 51, and the claw 51 and the sub-claw 53 engage with each other. Return to the state.

The above-mentioned operation knob 7 is of a push type operation mechanism, but as a means for releasing the holding lock mechanism 5, a pull-up type or a slide type operation knob can be adopted, and a link mechanism is also a suitable force transmission mechanism. Can be

As described above, the portion in which the operation knob 7 is provided is formed as a recess, but this is for making the presence of the push-type operation knob 7 inconspicuous, In the example shown in the figure, the effective setting position is a recessed position close to the rear shelf 31.

(Effect of the Invention) As described above, according to the present invention, the headrest has a gate-shaped structure, and the intermediate space portion secured by this gate-shaped structure acts as an access space for the operation knob, and the operation knob is Attached to the top part of the backrest surrounded by the headrest, this gives the operation knob a sense of unity with the backrest, making its presence unnoticeable, and adding the open feeling of the gate-type backrest to the exterior of the backrest. Since the operating knob is located in the center of the top of the backrest, the operability is improved and the entire backrest can be neatly configured, resulting in a rear seat with an appearance suitable for luxury cars. .
