Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vehicle seat in which a cargo platform can be formed by flipping up the seat portion of the seat and folding the backrest forward.

``Prior Art'' In a vehicle seat in which a cargo platform can be formed by flipping up the seat portion of the seat and folding the backrest forward, the seat portion is raised forward, the backrest is folded forward, and the backrest is folded forward. are firmly connected to stabilize the raised seat and increase the rigidity of the constructed cargo platform.

Conventionally, as the coupling means, a pin fitting is provided facing upward on the back of the seat, and a locking plate is provided on the backrest that is folded forward and has a small hole that fits into the pin fitting. It was getting worse.

``Problems to be solved by the invention'' However, in such a conventional combination of a pin fitting and a locking plate, when the backrest is tilted forward, the small hole of the locking plate is directly above the pin fitting. There was a problem in that the seats did not always come together properly, and in order to fit them properly, the seat had to be adjusted in the front, back, left, and right directions, which was time-consuming.

The present invention was created by focusing on these conventional problems, and even if the seat is flipped up and the backrest is casually thrown forward, the seat and backrest will automatically lock in place. It is an object of the present invention to provide a vehicle seat that is coupled to a vehicle seat.

``Means for Solving Problems'' The gist of the present invention to achieve this purpose is to create a cargo platform by flipping up the seat portion and folding the backrest forward. In the vehicle seat, in order to firmly connect the flipped-up seat portion and the backrest that is folded forward, the upper edge of the backrest that is folded forward is provided with at least one locking metal fitting having a locking hole; , an upward locking pin that fits into the locking metal fitting is provided on the back of the seat, and the locking pin is placed on the back of the backrest when the seat is raised and folded in order to guide the locking metal. The vehicle seat is characterized in that the guide recess is provided at the lowermost part of the guide recess, which opens upward when the seat is opened, and the lowermost part of the guide recess is provided in such a manner that the width of the locking metal fitting fits exactly with the width of the locking metal fitting.

``Operation'' When building a cargo platform, lift the rear end of the seat upwards and fold the backrest forward.

Even when the backrest is casually tilted forward, the locking metal fitting provided on the backrest is guided by the guide recess and the hole of the locking metal fitting and the locking pin naturally fit together.

When disassembling the cargo platform and returning it to a normal seat, the backrest that has been folded forward is raised and the seat is folded back to restore its original seat state.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

1 to 5 show an embodiment of the present invention.

In FIG. 3, the vehicle seat 10 constituting the cargo platform has a rear seat seat 11 located behind the front seat 1 of the vehicle that is normally folded forward around a hinge 18 at the front lower part of the seat 11. The backrest 12 is folded forward to form an expanded loading platform together with the original loading platform 2, and the back of the backrest is usually made of a steel plate suitable for forming the floor of the loading platform.

Therefore, in the present invention, as shown in FIGS. 1 and 2, there is at least one place on the steel plate of the back surface 13 of the seat, which opens wide upwards when the seat 11 is raised and falls, and becomes deeper and narrower toward the bottom. A guide recess 14 is provided. In this embodiment, as shown in the figure, two guide recesses 14 are provided on the left and right sides.

On the other hand, the guide recess 14 is located at the upper edge of the backrest 12.
A locking metal fitting 16 is provided at a position corresponding to.

The locking fitting 16 has a locking hole 16a into which a locking pin installed upright in the guide recess is fitted.

The locking metal fitting 16 is attached so that it is almost horizontal when the backrest is folded forward, and the front end 16b
is a flat side with no unevenness so as to come into contact with the guide front face 14c of the guide recess 14.

The length of the locking metal fitting 16 is approximately the same as the maximum depth L of the guide recess 14, and the width S2 of the locking metal fitting 16 is approximately the same as the minimum width S1 of the guiding recess 14.

That is, the guide recess 14 has a Y-shaped guide side surface 14a that extends upwardly when the seat section 11 is raised and lowered, and the guide side surface 14a becomes narrower and deeper toward the bottom. The lowermost part 14b of the guide recess 14 has the locking pin 15 erected thereon, and is horizontally flat so as to abut and receive the surface of the locking metal fitting 16 when the locking metal fitting 16 is fitted onto the locking pin 15. It is a face.

Next, the action will be explained.

To extend the cargo platform by moving the backrest 12 forward,
First, lift the rear part of the seat part 11 by hand and raise it up (FIGS. 3 and 4).

When the backrest 12 is folded forward, even if the seat portion 11 and the backrest 12 are slightly misaligned in the left-right direction,
Since the guide surface 14a of the guide recess 14 is wide open upward in a Y-shape, the locking fitting 16 descends along the guide surface 14a, and at the lowest part 14b of the guide recess 14, the width of the lowest part 14b is reduced. Since S1 and the width S2 of the locking metal fitting 16 are exactly matched,
The locking pin 15 fits into the locking hole 16 of the locking fitting 16.
Fit into a.

On the other hand, looking at the case where there is some excess or deficiency in the front and rear angles of the seat 11 that has been raised and lowered, first of all, if the seat is not raised enough, the front edge of the locking fitting 16
6b presses the guide front face 14c of the guide recess 14,
The locking pin 15 and the locking metal fitting 16 are locked while correcting the locking relationship position by themselves.

Further, when the seat portion 11 moves too far forward, the locking metal fitting 16 rides on the locking pin 15 and is temporarily stopped. However, even in this case, the left-right position of the seat 11 and the backrest 12 is maintained by the guide side 14a, so if you pull the seat slightly backward, the locking pin 15 will be inserted into the locking hole 16a. Fit into place.

"Effects of the Invention" According to the vehicle seat of the invention, the seat side of the connecting member that connects the seat and the backrest constituting the cargo platform has a Y that opens upward when the seat is raised and folded. The guide recess is shaped like a letter, and the width and depth of the lowest part of the guide recess are configured to match the width and length of the member on the backrest side. When configuring a cargo platform by folding forward, there is no need to concentrate on the connection between the seat and the backrest, and the backrest can be folded forward casually, saving effort and improving usability.
