Description

  The present invention relates to a seat mounting apparatus mounted on a vehicle, for example, an automobile.

  As a mounting device for a seat mounted on a conventional vehicle, for example, an automobile, a leg portion extends below a seat cushion that can be flipped up to a position substantially along the seat back, and is provided in a recess on the floor surface. A locking device is engaged with the striker (see, for example, Patent Document 1).

JP 2002-0676759 A

  However, in such a conventional mounting device, since the floor (also referred to as a floor) is provided with a recess and a striker, the seat cushion is covered with the use state and the seat cushion is stored. The exposed floor becomes uneven, and it will be difficult to place the luggage stably.

  The present invention has been made paying attention to such a conventional technique, and for a vehicle on which a load can be stably placed by obtaining a flat floor surface exposed in a seat cushion storage state. A seat mounting device is provided.

  According to the first aspect of the present invention, a seat back that is rotatable in a substantially horizontal direction around a vertical axis that is disposed at a position close to a side wall of a vehicle, and a front side that is supported by the seat back so as to be flipped up. A seat cushion for a vehicle, and a leg seat disposed on the left and right center side of the vehicle of the seat cushion, wherein the leg portion is in a use state of the seat cushion. A front member that can be placed on a floor surface, and a rear member that has a latch that can be engaged and disengaged with a striker disposed on the floor surface when the seat cushion is in use. The member is foldable to a lower portion of the seat cushion when the seat cushion is stored.

  According to a second aspect of the present invention, the front member and the rear member are coupled to each other by a first link so as to be able to rotate and rotate, and the rear member can flip up the seat cushion and The rear member can be held in a substantially vertical state by a second link connected by a rotating shaft that supports the seat back so as to be able to rotate back and forth.

  According to invention of Claim 1, a leg part is related with the striker distribute | arranged to the front side member which can be mounted on the floor surface in the use condition of the said seat cushion, and the said floor surface in the use condition of the said seat cushion. And a rear member having a latch that can be freely attached and detached, and when the front member and the rear member are foldable to the lower portion of the seat cushion when the seat cushion is stored, they are exposed when the seat cushion is stored. Only the striker is on the floor surface, and a substantially flat shape can be obtained, so that the luggage can be stably placed.

  According to invention of Claim 2, the said front side member and the said rear side member are connected with a 1st link so that it can cooperate and rotate, and the said rear side member can flip up the said seat cushion. Since the rear member can be held in a substantially vertical state by a second link connected by a rotating shaft that supports the seat back so as to be able to rotate back and forth, the seat cushion can be stored in a state of being flipped up to the stowed state. The rear member at the lower portion of the cushion can be held in a substantially vertical state by the second link. Further, since the rear member can be held in a substantially vertical state, the front member is folded to a position along the lower side of the seat cushion by the first link. Further, when the seat cushion is returned to the use state, the rear member is held in a substantially vertical state by the second link, so that the lower end portion of the rear member can immediately engage with the floor surface. In addition, since the front member can be placed on the floor surface away from the lower side of the seat cushion by the first link, the seat cushion can be stably held.

A headrest holder 4a that can be stopped at an appropriate position and can be held at that position, a holder bracket 4b that holds the headrest holder 4a to the first frame 3a, and linear shapes in the left and right directions IN and OUT of the first frame 3a And back springs 3b and 3b which are appropriately separated in the vertical direction and are fixed to the first frame 3a, and first and second upper arms 3c supported on both left and right sides of the first frame 3a. 3d.

  Reference numeral 16 in FIG. 4 and subsequent figures is a “vertical axis” which is disposed substantially perpendicular to the frame 21 at a position close to the side wall 7 and is supported by the frame 21 via a base frame 18 which will be described later by a nut not shown. It is a bolt. With the bolt 16 as a center, the base frame 18 extends substantially horizontally in the left-right direction which is the side wall 7 side, that is, the outer side OUT in the left-right direction and the left-right center side IN in the “use state” shown in FIGS. 8 is pivotally supported so as to be substantially horizontally rotatable at a position extending substantially horizontally in the front-rear direction FR, RR in the “retracted state” shown in FIG. Here, the term “abbreviated” means that both the base frame 18 and the bolt 16 are supported with a slight inclination and the bolt 16 is supported with a slight inclination. I mean. The base frame 18 has a hollow square cross section and is made of an iron plate.

  4 and 8 to 11, reference numeral 19 denotes a first surface 19 a disposed on the upper side UP of the upper surface of the base frame 18 and a second surface disposed on the lower side LWR of the lower surface of the base frame 18. 19b and a third surface 19c arranged on the rear side RR of the rear surface of the base frame 18, a stopper bracket formed in a U-shaped cross section so as to surround the base frame 18, It is pivotally supported so as to be rotatable in the horizontal direction. The meaning of the term “abbreviation” here is the same as that described in paragraph 0017. When the automobile seat 1 is in the “use state” shown in FIG. 4, the bolt 20, which is a “stopper” provided on the front side FR of the stopper bracket 19, as shown in FIG. 10, the base frame 18. Is engaged with the engaging portion 32 of the stopper block 31 fixed to the front surface of the stopper block 31 with screws 33. When the automobile seat 1 is in the “retracted state” shown in FIGS. 8 and 9, the bolt 20 as a “stopper” is outside the engaging portion 32 of the stopper block 31.

  The first frame 2a of the seat cushion 2 is connected to the base frame 18 via an arm 28 and is pivotally supported by a fifth pin 29 so as to be rotatable up and down. To be energized.

  The seat back 3 is supported by an end 18a of the vehicle frame OUT on the outside of the base frame 18 via a reclining device 17 that can be rotated in the front-rear direction.

One link. As shown in FIG. 6, one end of the reference numeral 26 is rotatably supported by the fifth pin 29 at the end 18 b on the left and right center side IN of the base frame 18, and the other is rotated by the rear member 9. It is the 2nd link pivotally supported by.

  Reference numeral 22 is a first operating member connected via a cable to operating means arranged in a cargo room (not shown), and reference numeral 23 is connected via a cable to operating means arranged in a cargo room (not shown). When the first operating member 22 is pulled to the rear side RR, the seat back 3 is unlocked from the reclining device 17 and the position shown in FIG. 6 is changed from the position shown in FIG. When the second operation member 23 is pulled to the rear side RR, the latch 10 of the rear side member 9 of the seat cushion 2 is released from the striker 11. Therefore, the front side FR of the seat cushion 2 can be lifted by the spring 25 from FIG. 6 to FIG.

  The operation of the embodiment of the present invention having the above configuration will be described below.

  Since the seat back 3 and the seat cushion 2 that is flipped up are stored along the side wall 7 of the vehicle, the bolt 16 that is the “vertical axis” disposed in the retracted state close to the side wall 7 of the vehicle is stored. As for the position of the inner surface of the side wall 7, the left and right OUT and IN width dimensions are not reduced, and the comfortability in the use state of the seat 1 can be improved. Moreover, since the seat back 3 can be operated at an appropriate inclination angle by the reclining device 17, the comfort in use can be improved.
