Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a vehicle seat in which a center seat is installed in the center of an installation location and outer seats are installed on both sides of the center seat.

"Prior Art" As a conventional vehicle seat, for example, there is one as shown in FIG.

That is, it is used for a fixed cab type vehicle in which an engine room is arranged below the floor 1, and a working opening (not shown) for repairing and inspecting the engine and the like is opened on the floor 1 to close the working opening. 2 is placed on the floor 1, the center seat 3 is fixedly mounted on the cover member 2, and the assist seat 4 has a substantially horizontal state and an inclined resting state via the angle adjusting mechanism 5. It is held so that it can tilt.

When the front end portion 6 of the cover member 2 is lifted, the hinge mechanism 7 rotates the cover member 2 about the rear end portion 8 to open an opening for work.

[Problems to be solved by the invention] However, in such a conventional vehicle seat, an angle adjusting mechanism 5 for putting the assist seat 4 in a resting state and a hinge mechanism 7 for rotating the cover member 2 are provided. Since they are provided separately, there is a problem that the configuration becomes complicated and the cost increases.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a vehicle seat that has a simple structure and can reduce costs.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to install a center seat in the center of the installation location and to install a driver seat or an assist seat next to the center seat. In a vehicle seat provided with an outer seat, the center seat and the outer seat are pivotally mounted so as to be relatively swingable, and both the center seat and the outer seat are in a substantially horizontal state. , An angle adjusting mechanism capable of holding one seat in a substantially horizontal state and the other seat in a resting state in which the other seat is inclined at a desired angle is provided, and the pivotal attachment portion between the center seat and the outer seat is opposite. The side end is engaged with a striker fixed to the installation place to keep both the seats in the substantially horizontal state so that they cannot be tilted. The present invention resides in a vehicle seat that is equipped with a lock mechanism for bundling.

[Operation] The center seat and the outer seat are fixed to the installation location by engaging the striker fixed to the installation location with the lock mechanism at the ends opposite to the pivotal attachment.

When the center seat and the outer seat are in a substantially horizontal state, for example, when the center seat is in a substantially horizontal position and the outer end portion of the outer seat is lifted, the outer seat swings with respect to the center seat. If the outer seat is held at a desired swing angle by the angle adjusting mechanism, an appropriate resting state can be achieved.

On the contrary, when the outer seat is made substantially horizontal and the outer end of the center seat is lifted, the center seat swings with respect to the outer seat. If the center seat is held at the desired swing angle by the angle adjustment mechanism, it will be in an appropriate standing state, and for example, the work opening that was opened at the installation location of the center seat can be opened, and the installation place can be opened through the work opening. You can see the engine room located below.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 5 show an embodiment of the present invention.

As shown in FIG. 1 and FIG. 2, in a fixed cab type vehicle, an engine room (not shown) is arranged below the vehicle body floor 10, which is the installation location. A central portion 11 of the vehicle body floor 10 in both sides is higher than both side portions 12, and a working opening 13 for repairing and inspecting an engine or the like is formed in the central portion 11 which is higher.

A lid body 14 for closing the working opening 13 is provided, and a heat insulating member 15 is attached to the back surface of the lid body 14.

A center seat 20 is arranged in a central portion 11 of the vehicle body floor 10, and a driver seat 30a and an assist seat 30 which are outer seats are arranged on both side portions 12, respectively.

As shown in FIGS. 1 and 4, the center seat 20
Is a panel frame 21 on which a pad member 22 is placed and which is covered with a skin member 23. On the other hand, the assist sheet 30 includes a plurality of S spring members 3 on the pipe frame 31.
2 is installed in a stretched state, and a plurality of S spring members 32 with pad members 33 placed thereon are covered with a skin member 34.

Support brackets 24, 24 are fixed to the front end and the rear end of the inside of the panel frame 21, respectively, and the inner end 31a of the pipe frame 31 is extended to each support bracket 24, and is pivoted by the pivot pin 25. Be pivoted as possible.

.. are engraved on the outer peripheral edge of the inner end 31a of the pipe frame 31. A pawl member 26 capable of meshing with the teeth 35, 35 when the inner end 31a of the pipe frame 31 tilts is pivotally supported by a pivot 27 fixed to the support bracket 24.

The pawl member 26 is biased counterclockwise in FIG. 4 about the pivot 27 so that the pawl member 26 meshes with the tooth portion 35 by the spring member 28. A disengagement member 36 that rides on the outer peripheral edge 37 of the claw member 26 so as to swing to a position where it cannot mesh with the tooth portion 35 against the biasing force of the spring member 28 is rotatable by the pivot pin 25. It is pivotally supported. At the end of the outer peripheral edge 37 of the disengagement member 36, the claw member 26 is attached to the outer peripheral edge 37.
A sloping edge 38 for guiding is formed so that the user can get on and off smoothly.

At the inner end 31a of the pipe frame 31, when the pipe frame 31 is in a substantially horizontal state as shown in FIG. 4,
A protrusion 39 for a stopper is formed so as to come into contact with the engagement release member 36 so that the engagement release member 36 does not rotate counterclockwise.

Similarly, at the inner end portion 31a of the pipe frame 31, as shown in FIG. 5, when the pipe frame 31 largely swings upright, the engagement releasing member 36 is prevented from rotating clockwise when the engagement releasing member 36 is rotated. A protrusion 39a for contacting with the stopper is formed.

The claw member 26, the spring member 28, the tooth portion 35, the mesh release member 36, and the like constitute an angle adjusting mechanism.

A center lock mechanism 40 is provided at an outer end portion of the center seat 20 to engage and disengage the striker 16 fixedly mounted on the vehicle body floor 10 to restrain the center seat 20 in a substantially horizontal state so that the center seat 20 cannot be tilted.
Is provided.

On the other hand, an assist lock mechanism 50 is provided at an outer end portion of the assist seat 30 to engage and disengage the striker 17 fixed to the vehicle body floor 10 to restrain the assist seat 30 in a substantially horizontal state so that the assist seat 30 cannot be tilted.

Next, the operation will be described.

As shown in FIG. 1, when the center seat 20 and the assist seat 30 are substantially horizontal, the center lock mechanism 40 and the assist lock mechanism 50 are engaged with the strikers 16 and 17, respectively.

In order to tilt the assist seat 30 to the resting state shown in FIG. 3, the assist lock mechanism 50 is used.
Leave from 7. Next, when the outer end portion of the assist seat 30 is lifted, the pipe frame 3 of the assist seat 30 is lifted.
The inner end 31a of No. 1 swings about the pivot pin 25 in the counterclockwise direction when viewed from the direction A in FIG.

As a result, the pawl member 26 is engaged with the tooth portion 35 one after another while pushing the guiding inclined edge 38 of the engagement releasing member 36. As a result, the engagement releasing member 36 maintains the position before tilting, and the distance between the stopper projection 39a and the contact portion of the engagement releasing member 36 is reduced.

When the lifting of the outer end portion of the assist seat 30 is stopped in the desired resting state, the claw member 26 meshes with one of the tooth portions 35 and the inner end portion 31 a of the pipe frame 31.
Is non-rotatably restrained clockwise about the pivot pin 25, whereby the assist seat 30 is held in a desired resting state.

When the assist seat 30 is largely swung so as to stand substantially vertically so as to move the assist seat 30 from the resting state shown in FIG. 3 to the substantially horizontal state shown in FIG. 1, the inner end portion of the pipe frame 31 is 31a further tilts counterclockwise around the pivot pin 25, and the stopper projection 39a comes into contact with the mesh release member 36 in due course.

Further, when the inner end portion 31a of the pipe frame 31 is further tilted counterclockwise about the pivot pin 25, the stopper projection 39a pushes the mesh release member 36,
The disengagement member 36 rotates counterclockwise about the pivot pin 25. As a result, the claw member 26 is pushed up by the guiding inclined edge 38 and rides on the outer peripheral edge 37 as shown in FIG. As a result, the claw member 26 is not meshed with the tooth portion 35, and the inner end portion 31a of the pipe frame 31 is tiltable in the clockwise direction about the pivot pin 25.

Next, when the outer end of the assist sheet 30 is lowered, the inner end 31a of the pipe frame 31 tilts clockwise around the pivot pin 25, and the stopper projection 39 is pressed by the claw member 26. The engagement release member 36 held at the position eventually contacts.

Further, when the inner end 31a of the pipe frame 31 tilts clockwise around the pivot pin 25, it is pushed by the stopper projection 39 and the disengagement member 36 moves about the pivot pin 25 in FIG. Then, the pawl member 26 slides on the outer peripheral edge 37 and slides down the inclined edge 38 for guiding, and as shown in FIG.
Mesh with.

Front and back, the assist sheet 30 becomes substantially horizontal as shown in FIG.

As shown in FIG. 1, when the center seat 20 and the assist seat 30 are substantially horizontal, the operation of lifting the outer end of the center seat 20 and holding the center seat 20 at a desired swing angle is performed as described above. This is relatively the same as the operation when tilting the 30 from the substantially horizontal state to the resting state, and therefore the description of the operation when holding the center seat 20 at a desired swing angle is omitted.

When the center seat 20 is tilted to a desired swing angle and held at that angle, the work opening 13 under the center seat 20 is opened, and the engine room can be seen through the work opening 13. Can be repaired and inspected.

In the above embodiment, the center seat 20 and the assist seat 30 are pivotally mounted so as to be swingable, but the center seat 20 and the driver seat 30a may be pivotally mounted.

[Advantage of the Invention] According to the vehicle seat of the present invention, only the angle adjusting mechanism is used to hold the center seat at a desired swing angle and open the working opening communicating with, for example, the engine room. At the same time, the outer seat is held at the desired swing angle to be in the resting state, so that the configuration is very simple and the cost can be reduced. Also,
The center seat and the outer seat, which are arranged adjacent to each other, are pivotally connected to each other and the end opposite to the pivot part is fixed to the installation location by the lock mechanism, so the seat can be easily installed. It is easy to handle and the cost can be reduced in terms of assembling.
