Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding sheet which is convenient for wagons, vans, recreational vehicles and the like.

[0002]

BACKGROUND ART In recent wagons and recreational vehicles, seats tend to be folded and made available in a flat condition. In the folding seat, the seat back sometimes needs to be operated while being supported, which is troublesome to operate.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a folding sheet which is simple and easy to operate and which can be safely folded and used in a flat state.

[0004]

[Means corresponding to the problem and its action]
A seat cushion that is supported on the floor side and is rotatable in a seated position and a folded position, and is arranged on the rear side of the seat cushion, and one end is on the front side of the seat back bracket and the other end is Is a sheet
Left and right front links that are hinged to the lower ends of the back sides, one end is appropriately separated rearward from the bracket-side hinge connection point of the front link, and the other end is located behind the seat back bracket. Fixedly attach the housing to the seat back bracket at the left and right rear links where the hinges are connected to the lower ends of the seat back sides, and the bracket side hinge connection points of the rear links, respectively, and A seat back that is rotatable into a seated position and a folded position by a rotary damper that connects the rear link to the rotor in a non-rotatable manner, and
Fold the seat back at the proper speed with the damper.

DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, the folding sheet of the present invention will be described based on the specified and illustrated specific examples.
1 and 2 schematically illustrate a folding sheet embodiment 10 of the present invention as utilized in a wagon third seat, and the third seat 10 includes:
A seat cushion 11 is supported on the side of the floor 30 and is rotatable in a seating position A and a folding position B, and a seat back 12 is arranged on the rear side of the seat cushion 11, and Left and right front links 1 whose one end is hinged to the front side of the seat back brackets 15, 15 and the other end is hingedly connected to the lower ends of the seat back sides 14 and 14 on the back and back sides, respectively.
6, 16, one end of the front link 16, 16 is appropriately rearwardly separated from the bracket-side hinge connection portion to the rear side of the seat back bracket 15, and the other end thereof is the seat back side 14, 14. The left and right rear links 17, 17 hingedly connected to the lower ends of the seats, and one of the left and right rear links 17, 17 on one bracket side hinge connection point of the housing 19 to one of the seat back brackets 15, 15. Fixedly attached to
Further, one of the left and right rear links 17, 17 is rotatable to a seating position C and a folding position D by a rotary damper 18 which is connected to the rotor 20 in a non-rotating manner, and further, the left and right head restraints 13, Thirteen
Is removably attached to the upper end of the seat back 12.

The rotary damper 18 generates a braking force by viscous resistance of silicon oil filled in a gap between a seat (not shown) incorporated in the housing 19 and the rotor 20. It is a disk damper.

Therefore, in the case of relaxing, the seat cushion 11 is first turned upside down and rotated from its seating position A to its folding position B.
Next, the head restraints 13, 13 are detached from the seat back 12, and the seat back 12 is moved forward. At that time, the seat back 12 is rotated from the seating position C to the folding position D at an appropriate speed by the disk damper 18 without being operated while supporting it. As such, the third seat 10 is smoothly converted to the flat state and becomes usable.

In the third seat 10, the rotary damper 18 is incorporated in the seat back 12 at the hinge-joining position. If the rotary damper 18 is a one-way rotary damper, the seat back will be omitted. 12 can stand up without using the braking force, and the operation becomes light.

As is apparent from the specific embodiments of the present invention described above with reference to the drawings, those skilled in the art to which the present invention pertains have a general knowledge of the present invention. Is the nature of the invention (na
It is easily embodied in another embodiment that is derived from the true) and the substance, and that is objectively recognized as having them internalized. Of course, the contents of the present invention correspond to the subject of the invention (be commensu).
rate with) and is essential for the establishment of the invention.

[0010]

Benefits of the Invention As can be seen from the above, the folding seat of the present invention includes a seat cushion supported on the floor side and rotatable in a sitting position and a folding position, and a rear portion of the seat cushion. The left and right front links, one end of which is hinged to the front side of the seat back bracket and the other end of which is hinged to the lower end side of the seat back side, and one end of which is the bracket side of the front link. The left and right rear links where the other end is hinged to the rear side of the seat back bracket and the other end is hinged to the lower end of the seat back side, respectively, as appropriate rearward from the hinge connection point, and the rear link The housing is fixedly attached to the seat back bracket at the bracket side hinge connection point, and The folding seat according to the invention is simple and easy to operate, and in particular because it includes a seat back that is rotatable in a seated position and a folded position by a rotary damper that locks the a-link to the rotor. , Its seat back can be safely folded without support and available in a flat condition, which makes it very useful and practical for wagons, vans, recreational vehicles, etc.
