Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a notebook device for an automobile, and more specifically,
This invention relates to the structure of a rear seat that can be folded and stored behind the front seat.

(Prior Art) As a prior art in the technical field to which the present invention pertains, there is, for example, the one described in Japanese Utility Model Application Publication No. 14548/1983.

However, in this known seat device, after the seat back is tilted to the top of the notebook cushion, it is raised toward the front of the vehicle using the front end of the notebook as a fulcrum, but the process of raising the notebook toward the front of the vehicle is difficult. In this case, the tilted seat hack sometimes interferes with the back of the front notebook notebook hack, which has the problem of poor operability.

(Problems to be Solved by the Invention) The present invention has been made in an attempt to solve the problems pointed out in the section of the prior art, and aims to facilitate the folding and storage operation of the seat. ).

(Means for Solving the Problems) The present invention has the following advantages:
Place the seat cushion on the sliding part (A) installed on the vehicle body side.
Through 1. The hinge member attached to the front end of the sliding part allows the sorting hack to be tilted forward with respect to the seat cushion, and the rear part of the notebook cushion can be slid forward and backward. a tenth fixing the rear end of the seat cushion to the sliding member side;
A 20th lock member is provided on the vehicle body side for locking or unlocking the sliding member, and further, the first lock member and the 20th lock member are connected to each other.
The 20th lock member is connected via the connecting member so that the 20th lock member performs the lock release operation in conjunction with the lock release operation of the 10th lock member.

(Function) In the present invention, the seat cushion can be slid in the longitudinal direction of the vehicle body via a sliding member provided on the vehicle body side, and can be tilted forward by a hinge member attached to the front end of the sliding member. By doing this, when the notebook cushion is raised in the 877 direction with the notebook back and tora in a forward tilted state, it is possible to allow backward movement using the front seat back as a guide, and the seat cushion A tenth lock member that fixes the rear end to the sliding member side, and a twentieth lock member that locks or unlocks the sliding member.
The tenth locking member is unlocked by connecting the locking member with the locking member via the connecting member so that the twentieth locking member performs the unlocking operation in conjunction with the unlocking operation of the tenth locking member. The effect of making the seat cushion rearwardly movable can be obtained by simply doing so.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

This notebook device is used as a rear seat SR of an automobile, and is composed of a seat cushion I and a seat hack 2 attached to the rear end of the notebook cushion I via a reclining device 3 so as to be tiltable forward. .

The front end of the bottom of the notebook cushion I is a slider that is slidably engaged with a rail-shaped guide member 6 that extends in the longitudinal direction of the vehicle body and is fixed on the floor 5 that constitutes a part of the vehicle body 4. -7 is attached to the front end via a hinge member 8 so as to be tiltable forward.

The hinge member 8 is attached to the frame 9 of the sorting cushion 1. The guide member 6 and the slider 7 are provided in pairs so as to support both sides of the bottom surface of the seat cushion 1.

A tenth hook member 11 for fixing the rear end of the seat cushion 1 to the rear end of the slider 7 is rotatably supported by a pin 12 on a bracket 10 fixed to the frame 9 at the rear of the sorting cushion 1. There is. The tenth locking member 11 has an operating portion 11a above the pin 12 and an engaging portion 11b below the pin 12, and is brought into the locked state by engaging the engaging portion i+b with the rear end of the slider 7. Be it. This tenth locking member 11 is always urged in the locking direction by a spring 13.

On the other hand, the bracket 1 fixed to the upper surface of the slider 7
4, a twentieth lock member 15 which acts to lock or unlock the slider 7 is rotatably supported by a pin I6.

The 20th hook H15 has a lever shape and is connected to the pin I.
It consists of an operating part 15a in front of the pin 16 and an engaging part 15b in the rear of the pin 16. A claw piece 18 that engages with a locking portion 17.17 formed at the rear portion of the guide member 6 is integrally provided on the engaging portion 15b. (See Figure 3)
. That is, the locking portion 17. of the guide 31'+4'ti.
By engaging the claw piece 18 with one of the sliders 17, the slider 7 is locked at the selected position. Reference numeral 19 indicates a hole formed on the side surface of the slider 7 for inserting a claw piece. This 20th locking member 15 is always urged in the locking direction by a spring 20.

Part 1. The engaging portion 11b of the tenth hook member 11 and the arm portion 15c protruding from the side of the pin 16 in the twentieth hook portion 15 are connected via a wire 21 which is a connecting member. . In other words, in conjunction with the unlocking operation (moving in the direction of arrow B) of the 10th locking part 4A11, the 20th locking part 15 is configured to perform the unlocking operation (moving in the direction of arrow B). It is. In addition, wire 2!
The outer skin 21a is fixed between a bracket 22 fixed to the side surface of the seat cover 1 and a bracket I/23 fixed to the two sides of the slider 7.

The illustrated notebook device operates as follows.

As shown in Fig. 4 (a), after tilting the notebook hack 2 of the rear seat Sg to the notebook cushion 10, operate the 10th lock part 11 in the direction of the arrow to release the lock, and at the same time The 20th hook member 15 is interlocked in the direction of arrow B via the wire 2I (7, the slider 7 is unlocked. In this state, the seat cushion 1 is moved from the hinge member 8 as shown in FIG. 4(b). When the seat back 2 is raised forward as a fulcrum, the seat back 2 contacts and is guided by the sorting back of the front notebook SF, and the notebook cushion 1 and the slider 7 move backward by the required amount, as shown in Fig. 4 (H). ) The illustrated standing state can be easily obtained.Then, when the hand is released from the tenth hook member II, the second
The locking member 15 automatically locks the slider 7 by the biasing force of the spring 20.

(Effects of the Invention) As described above, according to the present invention, the tenth screw fixes the rear end of the seat cushion, which is slidable in the longitudinal direction with respect to the vehicle body via the sliding member, to the sliding member side. The member and the 20th Tsuku part shrine which locks or unlocks the sliding member are connected via a connecting member, and the 20th Tsuku part shrine is unlocked in conjunction with the unlocking operation of the 10th Tsuku part shrine. By unlocking the 10th hook member, the seat cushion can be moved freely in the longitudinal direction of the vehicle, making it extremely easy to raise and store the seat without interfering with the front notebook. There are some good effects that can be done.
