Description

[Detailed description of the invention] "Industrial application field" This invention is a vehicle seat equipped with a removable headrest on the upper edge of the backrest. The present invention relates to a vehicle seat that constitutes a loading platform.

``Prior Art'' In a vehicle seat in which a cargo platform can be constructed from a seat and a backrest, when constructing the cargo platform, a connecting member on the backrest side, which is a coupling means for coupling both, is used.
An example of a device related to the headrest of a seat is disclosed in Japanese Utility Model Application Publication No. 116229/1983.

According to the above-mentioned publication, an insertion opening for a headrest attachment stay is formed in the coupling member provided at the upper edge of the backrest.

``Problem that the invention aims to solve'' However, in such conventional vehicle seats, the long metal stay that protrudes below the headrest constitutes a loading platform, so it is dangerous and obstructive when the headrest is removed. However, there was a problem in that it was difficult to store the removed headrest.

The present invention was developed by focusing on these conventional problems, and the connecting member of the backrest, which is folded forward to form a loading platform, and the seat part is also used as a component of the headrest. The purpose is to provide a vehicle seat that is free of dangerous and difficult-to-handle protrusions.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is that the seat can be flipped up and the backrest can be folded forward to form a cargo platform. In a vehicle seat equipped with a removable headrest on the upper edge of the backrest, the headrest is attached to the position where the upper edge of the seatback is close to the seat and the upper edge of the backrest, respectively, so that they can be connected to each other when configuring the cargo platform. The backrest side connecting member is an inverted U-shaped steel bar with a circular cross section and short legs formed at both ends of a horizontal locking part so as to serve as a stay for the headrest. It is shaped like a letter, and is provided on the upper edge of the backrest so as to protrude slightly upward by the length of the short legs.The headrest has a mounting part inside, and the end of the mounting part corresponds to the lower end of the headrest. , a notch having a biting opening into which the backrest-side connecting member is inserted is provided at the lower end, and when the headrest is attached, the locking part reaches the position where the connecting member is fitted inside and wrapped. The invention resides in a vehicle seat characterized in that it is provided with a fitting portion into which the locking portion is fitted.

``Function'' When using the seat as a seat with the seat folded down and the backrest upright, the headrest should be wrapped around the connecting member that protrudes from the upper edge of the backrest and connects to the seat. and insert it.

When the headrest is completed, the connecting member on the backrest side functions as a stay for the headrest.

The head rest is fitted so as to surround the coupling member from the outside, and functions as a headrest and also serves to protect the seated person's head from hitting the coupling member. Since the headrest is fitted into a horizontal locking portion with a circular cross section of the connecting member on the backrest side, when the occupant leans back, the headrest can be rotated to change its posture to suit the head.

To construct a cargo platform by raising and lowering the seat and folding the backrest forward, first, the headrest is removed from the connecting member on the backrest side that also serves as a stay.

Since there is no hard object protruding from the outside of the flexible headrest in the headrest removed from the coupling member, care is not required to handle it, and there is no need for storage space in the vehicle.

When the backrest is folded forward, the connecting member from which the headrest has been removed is fitted into the connecting member on the seat side to form a cargo platform.

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

The vehicle seat 10 consists of a seat part 11 that flips forward about a hinge 13, and a backrest 12 that folds forward about a hinge 14. When constructed, they are connected by a connecting means 15 consisting of connecting members 16 and 17, respectively, to maintain the integrity of the cargo platform.

Of the coupling means 15, the back surface 11 of the seat portion 11
As shown in FIG. 4, the coupling member 16 provided at the portion a is provided with a locking groove 16a that opens upward when the seat portion 11 is raised and lowered.

Although there are two locking members 16 on the seat side in FIG. 4, one may be used depending on the shape and size of the connecting member 17 on the backrest side.

On the other hand, the connecting member 17 on the backrest side is connected to the backrest 12.
As shown in FIG. 2, when it is tilted forward, it fits into the locking groove 16a of the coupling member 16 on the seat 11 side and is coupled.

The connecting member 17 on the backrest 12 side is made by bending a steel bar in this embodiment, but in other embodiments, it may be made by providing a locking hole in a steel plate, for example. In this case, the connecting member 16 on the seat portion 11 side also has a shape and structure corresponding to that.

Next, the fifth headrest 20 is fitted so as to wrap the connecting member 17 on the backrest 12 side from the outside.
As shown in FIG.

The headrest 20 consists of a cushion part 25 and a mounting part 30 that fits into the coupling member 17 which also serves as a stay.

The cushion part 25 has a pad part 26 filled with cotton felt, latex foam, urethane foam, etc., and an outer skin 2 made of various artificial leathers.
It consists of 7.

As shown in FIG. 6, the mounting portion 30 is long in proportion to the coupling member 17, and is held deeply sunk within the cushion portion 25.

The mounting portion 30 is formed of an elastic material such as tetrafluoroethylene, which elastically opens when the coupling member 17 is pushed in, and has elasticity on the side that always closes, such as tetrafluoroethylene. A notch 31 into which the coupling member 17 is inserted is provided along almost the entire length.

Furthermore, a fitting portion 30 that matches the cross-sectional shape of the coupling member 17 is provided at the back of the notch 31 .

The fitting portion 32 has a circular cross section, which prevents concentration of stress and improves durability.

On the other hand, the biting opening 33 of the notch 31 is formed into a large V-shape so that the notch 31 can easily open when pressed against the coupling member 17.

Note that the depth of the notch 31 and the height of the connecting member 17 on the backrest 12 side are approximately the same, and when the headrest 20 is pushed into the connecting member 17, the lower surface 28 of the cushion of the headrest 20 is exactly as shown in FIG. It is adapted to be in contact with the upper edge surface of the backrest 12.

Next, the action will be explained.

For example, as shown in FIG. 2, the area under the seat portion 11 of the seat is suitable as a storage location for the headrest. Further, since the headrest 20 does not have any dangerous metal protrusions on the outside, it may be used as an armrest for a passenger seated on the front seat of a vehicle.

Next, the seat portion 11 is tilted forward about the hinge 13, and the backrest 12 is tilted forward.

The connecting member 17 of the backrest 12 is fitted into the locking groove 16a of the connecting member 16 on the side of the seat 11 provided on the back surface of the seat 11, thereby completing the construction of the cargo platform.

To restore the state from the loading platform to the normal seat state, raise the backrest 12 in the opposite manner to the above, and then fold the seat 11 back to the seat state.
When applied to the locking part 17a of the coupling member 17 and pushing down strongly, the notch 31 will open naturally and the locking part 17a will fit into the fitting part 32 of the headrest 20.
At the same time, the installation of the headrest 20 is completed, and at the same time, the restoration of the seat 10 is also completed.

"Effect of the invention" According to the vehicle seat according to the invention, when a cargo platform is constructed by the seat part and the backrest of the seat, the joining member on the backrest side of the connecting means for joining the seat part and the backrest is It also serves as a stay for the headrest, and since the headrest wraps around the coupling member from the outside, the headrest itself does not require any dangerous protrusions that protrude to the outside, making it easy to handle the headrest that has been removed for the purpose of constructing a cargo platform. It is safe, easy to store, and can be used as an armrest for passengers. When using the headrest, when the occupant leans back, the headrest can be rotated to suit the position of the head, which is convenient.
