Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a folding rear seat device for a vehicle in which a portion of the palm seat pack is folded forward so that the seat can pass through the vehicle interior and the trunk room.

A trunk seat set in which a part of the rear seat back can be folded forward for the purpose of making effective use of the rear space in the vehicle, and the rear seat back space in the vehicle interior and the space in the trunk room are connected to each other when the rear seat back is folded forward. A folding rear seat device has been proposed and put into practical use.

In the folding rear seat device described above, the engagement between the folding part and the vehicle body side is released by pulling the pull-out belt provided on a part of the rear seat back, and the folding part rotates using the lower end as a hinge. As a result, the opening on the rear surface of the folding portion is opened, and the rear space in the vehicle interior and the trunk space communicate with each other through the opening.

By the way, when you turn the foldable part upright and bring its surface flush with the surface of other parts of the rear seat back, the locking mechanism is a self-locking type, so the folding part and the vehicle body side will immediately engage. Therefore, if the retractable portion is inadvertently raised, the opening between the trunk and the trunk will be closed and locked, making it impossible to open the trunk from inside the trunk.

The inconvenience caused by this is, for example, if the folding part is moved forward and a child enters the trunk through the opening, the child may not notice this, or may carelessly flip up the folding part, causing the above-mentioned problem. The folding part stands up to close and lock the opening, making it difficult for the folding part to fall forward and open from inside the trunk, resulting in the child being trapped in the trunk.

The present inventor devised this invention in order to prevent the above-mentioned inconveniences in this kind of rear seat device with a trunk seat. An intermediate closing member that closes the opening is interposed so as to be able to fall forward, and the intermediate closing member can be locked when the opening is closed, and the locking mechanism of the intermediate closing member can be locked only by forced and conscious manual operation. It is designed so that it can be engaged with the locking member on the side, so that even if the forward folding part of the seat back is carelessly flipped up, the opening will not be closed and locked, but only with a conscious and forced operation. The intermediate closing member closes and locks the opening between the trunk and the trunk, and locks the foldable part of the seat back in the upright position, thereby preventing children and others from being trapped in the trunk. To provide a collapsible rear seat device for a vehicle whose structure can be designed simply while ensuring a collapsible part of a rear seat back without impairing its usability.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figures 1 to 3 are perspective views illustrating the folding operation of the beam palm seat pack, in which the rear seat 1 of the vehicle has a rear seat cushion 2 attached to the floor as is known, and a rear seat cushion 2 that is erected at an angle at the rear end of the seat cushion 2. A folding part 4 is provided in a part of the rear seat back 3, which is made up of a palm seat pack 3, and a part of the bulkhead 6 of the trunk room 5 on the back side of the folding part 4 is formed with an open lower part.

To explain this specifically with reference to FIG. is formed with an opening 3a for storing the foldable part,
A portion of the partition wall 6 that corresponds to the back surface of the opening 3a is opened.

A locking hook portion 9 is provided on a part of the upper back surface of the foldable portion 4, and this hook portion 9 is connected to a locking claw 10 attached to the partition wall 6 or the base plate 3b on the seat back 3 side and the opening 3a.
, 7 are closed, and the engagement waist retractable portion 4 is locked.

Then, by pulling the pull-out belt 11 attached to the collapsible portion 4, the engagement between the locking pawl 10 and the hook portion 9 is released, and the collapsible portion 4 is tilted forward by the operation of the link 8.

This locking pawl 10 is in a fixed position and the foldable part 4 is fitted into the opening 3a of the rear seat back 3, and the hook part 9 and the surface of the foldable part 4 and the surface of the palm seat pack 3 are in the same position. Locks and self-locks.

A safety panel 12, which is an intermediate closing member, is attached to the back side of the foldable portion 4, and the safety panel 12 is pivotally attached to the lower end of the rear seat back base plate 3b, for example, with support rods 13 protruding from both sides of the lower end, and the opening 3a, A locking claw 14 is attached to a part of the upper part of the locking claw 14.
is rotatably mounted on the back surface of a recess 12a provided in a part of the upper part of the panel, and is connected to an operating knob 15 housed in the surface of the recess 12a.
5 and the locking pawl 14 are always elastically biased in the locking direction.

When the opening is closed, the claw portion 14a is attached to the base plate 3b.
The waist-attached panel 12 is supported with the opening closed so that the upper end 12b of the panel abuts the back surface of the locking portion 3c extending from the side, and the upper end 12b of the panel is on the surface of the locking portion 3C.

A key mechanism 15a is provided on the surface of the knob 15, and a member such as a coin or an ignition key can be inserted into the key mechanism 15a.
The knob 15 rotates only by engaging with and twisting the claw portion 14a.
is rotated to release the engagement with the locking portion 3c, and the panel 12 is moved forward so that the lower opening can be opened.

Instead of the above, the locking pawl may be released by two tricky movements.

Further, although the safety panel 12 is shown as a blind plate in the figure, it may be in the form of a grid.

In the above process, the foldable part 4 forming a part of the rear seat back 3 as shown in FIG. The fallen part 4 leaves.

In this state, the safety panel 12 still closes the opening,
Rotate the knob 15 using a coin or the like to release the engagement between the claw portion 14a of the locking claw 14 and the extended locking portion 3c, and move the safety panel 12 forward.

In this way, the opening lower part is completely opened, and the rear part of the vehicle interior and the inside of the trunk room 5 communicate with each other, as shown in FIG.

By the way, when attempting to close the open lower door, that is, when returning it to its original position, it is necessary to first raise the safety panel 12, close the opening, and then raise the retractable portion 4, store it in the opening 3a, and close it. be.

In the safety panel 12, the locking claw 14 of the knob 15 is connected to the spring 1.
6 to return to the locking position and raise the panel 12, the locking pawl 14 hits the outside of the locking part 3c at the upper edge of the opening, so the panel 12 cannot be closed, and in this state, the foldable part The opening cannot be closed even if the cell block is raised, and the cell block position has not yet been reached.

Therefore, even if a child were to enter the trunk, the safety panel 12 and the foldable part 4 are not locked, so the panel 12 and the foldable part 4 can be easily opened by pushing the safety panel 12 forward. .

When closing the opening, it is necessary to intentionally and consciously lock the panel 12 via the knob, and in this case, the operator must do so while visually checking the opening and confirming the situation inside the luggage compartment. This avoids a situation where a child enters the trunk room and unintentionally closes the opening.

After locking the panel 12, the foldable portion can be locked in an upright position,
Therefore, since the above operations are involved, it is possible to prevent operations caused by children's mischief.

As is clear from the above, according to the present invention, in a vehicle in which a part of the rear seat back of the vehicle is folded forward to allow communication between the trunk and the trunk, children can enter the trunk, and the opening can be blocked by self-locking. In addition to avoiding these inconveniences, we have achieved the above by interposing an intermediate closing member and consciously and forcibly manipulating the locking mechanism, thereby making significant changes to conventional devices of this type. The structure is simple and can be achieved by adding a minimum number of parts, which is beneficial in terms of safety.
