Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile seat, and more particularly, to the structure of a seat having a flip-up seat cushion.

(Prior Art) As is well known, for example, in the case of a rear seat in a van-type automobile, for the purpose of expanding the luggage compartment, the front side of the seat cushion is used as a fulcrum to rotate and flip up the rear seat toward the front seat side. There is a structure.

As shown in the third diagram, such a seat 1 is provided with a fulcrum shaft (not shown) in the pipe frame 2 located on the front side inside the seat cushion 1A. It can be rotated as a fulcrum and raised into a so-called flip-up position.

On the other hand, the interior of the seat cushion 1A is provided with a locking mechanism that can set the seat cushion 1A to a seatable position and a flip-up position.

This locking mechanism includes an angular locking member 4 whose base is pivotally connected to a support shaft 3 provided on a part of a pipe frame 2 and which is swingable, and a swinging end side of the locking member 4. The operating strap 5 is attached at one end and extends from the other end to the seating surface of the seat cushion 1A.

The locking member 4 normally has a swinging end in FIG. 4 that is pivoted in a direction that allows it to engage with a locking rod 6 supported by a rear cross member (not shown) on the vehicle body side, for example. empowered.

Then, the strap 5 is as shown in the fourth diagram.
The other end is inserted through a tunnel-shaped presser member 7 fixed to the back surface of the seat cushion 1A and extends to the seating surface of the seat cushion 1A, and the end is a bag-shaped gripping part. ing.

In this structure, the seat cushion 1A is flipped up by pulling the strap 5 to release the engagement between the locking member 4 and the locking rod 6.

(Problem to be solved by the invention) By the way, in the case of such a seat, when the seat cushion 1A is raised and flipped up toward the front seat side, the other end of the strap 5 will not touch the inside of the presser member 7. Since it is merely inserted, there is a risk that it may come off from the holding member 7 due to gravity or careless external force, as shown by the two-dot chain line in Fig. 4. If the seat cushion 1A is folded away, it becomes difficult to disengage the locking member when attempting to flip up the seat cushion 1A again.

SUMMARY OF THE INVENTION In view of the problems with conventional flip-up seats, it is an object of the present invention to provide a seat that prevents straps from slipping out or falling off, and allows the seat cushion to be flipped up at any time.

(Means for Solving the Problems) The present invention includes a seat cushion that can be raised and folded using the front part as a fulcrum, and a locking mechanism that is disposed at the lower part of the seat cushion and that can be connected to and detached from the vehicle body structure. a locking member, a tunnel-shaped pressing member fixed to the back surface of the seat cushion, one end of which is attached to the locking member, and the free end of which passes through the pressing member to seat the seat cushion. After extending to the rear of the seating surface and folding back the extending portion, the folded tip is fixed to a fixed portion located between the position where the free end passes through the presser member and the rear end of the seating surface. In the sheet having a strap fixed to the free end, the strap is attached between a position where the one end is attached to the locking member and a position where the free end enters the presser member. An auxiliary strap is provided with a proximal end fixed to the strap, and has a locking end extending from the proximal end through the upper part of the presser member to a position opposite to the fixed portion, and a distal end of the locking end. It is characterized in that the fixing portion and the fixing portion are provided with engaging/disengaging means that can be engaged with and detached from each other.

(Function) According to the present invention, the presser member is surrounded by the free end of the strap that is inserted into the presser member and the auxiliary strap that wraps around the outside of the presser member. In addition, since the strap and the auxiliary strap are configured to be able to be freely engaged and detached at the fixed part,
Even if an external force is applied in the direction of disengagement when the two are engaged, this engaging portion will be caught on the presser member.

(Embodiment) FIG. 1 is a side view showing a seat cushion constituting an automobile seat according to an embodiment of the present invention, and structural parts that are the same as those shown in FIG. 3 are designated by the same reference numerals. Detailed explanations of each will be omitted.

In the same figure, the strap 10 whose one end 10e is attached to the locking member 4 is made of a material woven with cloth like a seat belt, and its free end 10a is inserted into the inside of the presser member 7. It is inserted and extends to the rear of the seating surface of the seat cushion 1A, and is folded back to form a bag-shaped extension part 10b. The folded end portion 10c is fixed at the fixed portion 10d located between the position where the free end portion 10a passes through the inside of the presser member 7 and the rear end portion 1B of the seating surface of the seat cushion 1A. It is sewn and fixed. One side 11a of a hook 11, which is an engaging/disengaging means, is fixed to the fixed portion 10d.

On the other hand, the position where one end 10e of the strap 10 is attached to the locking member 4, and the position where the free end 10a
An auxiliary strap 12 is provided with its proximal end 12a sewn to the strap 10 between the position where the strap 12 is about to enter the inside of the presser member 7. The locking end 12b of the auxiliary strap 12 extending from the base end 12a is directed toward the fixing part 10d via the upper part of the presser member 7, and the length from the base end 12a to the distal end 12c is is set to be slightly longer than the length of the free end portion 10a of the strap 10 from the position where the auxiliary strap 12 is sewn to the fixed portion 10d. And at the tip 12c,
One side 11a of the hook 11 provided at the fixing portion 10d of the strap 10 and the other side 11b of the hook 11 corresponding to the other side 11b of the hook 11 are fixed, and the strap 10
and the auxiliary strap 12, as shown in FIG.
It is removably integrated with a hook 11 provided at the fixed portion 10d.

Since this embodiment has the above-described structure, one end 10e of the strap 10 is attached to the locking member 4, and then the free end 10a is inserted into the presser member 7, so that the position of the fixed portion 10d is adjusted to the presser member 7. The free end portion 10a is pulled out from the presser member 7 so as to be located on the way to the rear end portion 1B of the seating surface of the seat cushion 1A, and the extending portion 10b is extended to the seating surface of the seat cushion 1A. Then, by detouring the auxiliary strap 12 from the outside of the presser member 7 and engaging the hook 11, the strap 1
0 and the auxiliary strap 12 surround the holding member 7.

Therefore, when the seat cushion 1A is flipped up, the extending portion 10b of the strap 10 will slide down from the rear end portion 1B of the seating surface of the seat cushion 1A, as shown by the two-dot chain line in FIG. Even if it is, it is caught on the auxiliary strap 12 engaged at the fixing portion 10d, and is prevented from slipping down.

(Effects of the invention) According to the invention, the auxiliary strap is provided on the operating strap of the locking member used to disengage the seat cushion from the vehicle body structure, and the strap is surrounded by the holding member of the strap. It is possible to securely prevent the strap from coming off, and the extending portion of the strap can always be exposed from the seating surface of the seat cushion, making it possible to easily flip up the seat cushion at any time. Since the strap and the auxiliary strap are made detachable, the strap can be easily attached and detached.
