Description

[Detailed Description of the Invention] This invention relates to a storage device for storing a folding vehicle seat when not in use.

In a conventional storage device of this type, for example, FIG.
As shown in FIG. 2, a link is provided that spans the back frame f of the seat bag s and the cushion leg in order to hold the cushion leg in an upright position when the cushion c is unfolded and to hold the cushion leg in a collapsed position when the cushion c is folded. r and a band b for connecting the folded cushion leg to the upper end of the back frame f, necessitating two operations for storage, and the storage mechanism becomes complicated, resulting in increased weight, number of parts, and The drawback was that the number of manufacturing steps increased.

In view of the above reasons, an object of the present invention is to provide a storage device for a vehicle seat that can simplify the storage mechanism and make the storage operation one-touch. In order to support the seat cushion connected to the seat cushion so as to be foldable and deployable, the cushion leg attached to the seat cushion so as to be foldable and deployable is always biased by a spring in the direction in which the cushion leg is deployed. On the other hand, there is provided a storage device which is provided with a storage band for releasably anchoring the cushion leg in the folded state to the back frame and holding the seat cushion in the folded state to the back frame via the cushion leg. That is.

Next, the first embodiment of the present invention will be explained with reference to FIGS. 3 to 6. In the figures, reference numeral 1 stands up on the floor of the vehicle to support the seat back 2 of the vehicle seat s. It is a back frame, and a substantially shaped fixed locking piece 3 is screwed to the center of the rear side of the horizontal rod 1a at the upper end thereof and projects upward.

Reference numeral 4 denotes a seat cushion which is foldably and unfoldably connected to both vertical rods 1b of the back frame 1 via a connecting member 5, and whose back surface 4a
A band guide 6 is fixed to the central part of the
A seat cushion 4 is provided in the center of the front end 4b.
In the unfolded state, the storage bag 7 is open in the vertical direction and has an insertion opening 7a that opens upward and widens toward the end.
is fixed.

Reference numeral 8 denotes a substantially shaped cushion leg which is attached to the lower front end of the seat cushion 4 so as to be foldable and deployable in order to support the seat cushion 4 when it is deployed, and is fitted to the base ends on both sides thereof. The attached connecting pieces 8a, 8a are attached to a bracket 9 fixed to a horizontal rod 9 at the front end of the seat cushion 4.
a, 9a through a pin 10, and is always biased in the deployment direction by a torsion spring 11 wound around the pin 10 and hooked at both ends to the connecting piece 8a and the bracket 9a. When the seat cushion 4 is expanded, it is held in an upright state by the elastic force of the torsion spring 11.

Reference numeral 12 denotes a bendable storage band attached to the cushion leg 8, the base end 12a of which is connected to a movable locking piece 13 fixed to the center of the horizontal rod 8b of the cushion leg 8. On the other hand, a hook is provided at the tip 12b of the cushion leg 8 in a folded state to be removably hooked to the fixed locking piece 3 of the back frame 1 in order to restrict the expansion of the cushion leg 8 and to anchor it to the back frame 1. Metal fittings 1
4 are connected to each other, and when the seat cushion 4 and the cushion legs 8 are unfolded, the latch 14 and the vicinity of the tip 12b are stored in the storage bag 7, while the seat cushion 4 and the cushion legs 8 are folded. In this state, when the storage band 12 is extended so that the band guide 6 and the storage bag 7 are bent upward and backward into a substantially L-shape, and the latching metal fitting 14 is latched to the fixed latching piece 3 of the back frame 1. The cushion leg 8 is tied to the fixed locking piece 3, and the seat cushion 4 is attached to the back frame 1.
The seat cushion 4 and the cushion leg 8 can be respectively stored in an upright state in parallel.

Next, the operation and effects of the first embodiment having the above-described configuration will be explained.

Now, in this example, a cushion leg 8 is attached to the seat cushion 4 so that it can be folded and unfolded, and a torsion spring 11 is provided at a connecting portion between the seat cushion 4 and the cushion leg 8.
While the cushion leg 8 is always biased in the unfolding direction, the cushion leg 8 is biased when the seat cushion 4 and the cushion leg 8 are folded.
A storage band 12 is attached to the seat cushion 4 for releasably anchoring the seat cushion 4 to the back frame 1 via cushion legs 8 in an upright state.

Therefore, the seat cushion 4 and the cushion leg 8 can be connected to and removed from the fixed locking piece of the back frame 1 and the locking fitting 14 of the storage band 12.
The seat cushion 4 and the cushion leg 8 are respectively stored in a folded state and are in a stored state.
This has the effect that the seat cushion 4 and cushion legs 8 can be stored and expanded with a single touch.

In addition, since the seat cushion 4 and the cushion legs 8 can be connected to the back frame 1 at the same time using the storage band 12, the mechanism for storing the seat cushion 4 and the cushion legs 8 can be simplified, reducing the overall weight of the seat and reducing the number of parts. It is possible to reduce the number of manufacturing steps and the number of manufacturing steps, which in turn can reduce manufacturing costs.

Next, a second embodiment of the present invention will be explained with reference to FIGS. 7 and 8. In this example, when the seat cushion 4A is stored, the cushion leg 8A is moored to the back frame 1A on one side of the seat cushion 4A. In order to
2aA is pivotally attached to a fixed locking piece A provided on one side of the vertical frame of the back frame 1A, and a latch fitting 14A connected to the tip thereof is attached to the cushion leg 8.
The seat cushion 4A is attached to the back frame 1A so as to be removably hooked to the movable locking piece 13A fixed near the lower end of the vertical rod 8C of A.
A storage band 12A in contact with one side 4C of the seat cushion 4A is configured to hold the seat cushion 4A against the back frame 1A via the cushion leg 8A, thereby storing the seat cushion 4A and the cushion leg 8A.

The functions and effects of the second embodiment are explained in the first embodiment.
Since it is almost the same as the embodiment, its explanation will be omitted.

That is, the present invention provides a seat cushion which is foldably and unfoldably connected to a back frame for supporting the seat back of a vehicle seat, and which is foldably and unfoldably attached to the seat cushion in order to support the seat cushion when unfolded. While the seat cushion legs are normally biased by springs in the unfolding direction of the cushion legs, the cushion legs in the folded state are releasably anchored to the back frame, and the seat cushions in the folded state are attached to the back frame. By attaching a storage band for holding the seat in place, the storage mechanism and storage operation can be simplified, making this an extremely practical idea as a vehicle seat storage device.
