Abstract

(57) [Abstract] [Purpose] The present invention aims to avoid interference of obstacles adjacent to the seat when the seat is rotated. [Structure] Side edge 2C of seat 2A of seat 2 on the side of obstacle 1
Can be flipped up and the side edge portion 2C is flipped up to avoid the interference of the obstacle 1 when the seat 2 rotates.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating seat installed in, for example, an automobile.

[0002]

[Prior art]

 For example, as shown in FIG. 8, a two-seat seat (1) and a one-seat seat (2) may be installed side by side in a vehicle so as to be rotatable front and back. In this case, for example, when rotating the one-person seat (2) in the direction of arrow A, the two-person seat (1), which is an adjacent obstacle, interferes and cannot rotate by 180 °. Therefore, conventionally, the corners of the seat portion (2A) of the one-person seat (2) are matched with the arc shape around the rotation center P as shown by the dotted line to avoid the interference of the two-person seat (1) Is taken. This situation is the same when the two-seat seat (1) is rotated.

[0003]

[Problems to be solved by the device]

 However, as described above, when the corner portion of the seat portion (2A) of the seat (2) is formed in an arc shape, the left and right shapes of the seat portion (2A) are different and the shape becomes distorted.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention is a seat (2) rotatably installed in the front and rear on a floor F, and an obstacle (1) is adjacent to the seat (2). The present invention provides a rotating seat (2) capable of flipping up the seat (2A) side edge (2C) of the seat (2) on the obstacle (1) side.

[0005]

[Action]

 When rotating the seat (2) from the front to the rear, the side edge (2C) of the seat (2A) of the seat (2) on the obstacle (1) side is flipped upward. Then, the seat (2) can be rotated in the rearward direction without the side edge (2C) of the seat (2A) of the seat (2) interfering with the obstacle (1).

[0006]

【Example】

The present invention will be described with reference to an embodiment shown in FIGS. 1 to 7. (1) is a two-seater seat, which comprises a seat (1A) and a backrest (1B), and (2) is one person. It is a hanging seat, and similarly comprises a seat portion (2A) and a backrest portion (2B). The seats (1, 2) are rotatably installed on the floor F in the front-rear direction, but the side edge portion (2C) on the seat (1) side of the seat portion (2A) of the seat (2) is moved upward. It is possible to flip up. In the state in which the side edge portion (2C) of the seat (1) side of the seat (2) is flipped up as shown in FIG. 3, the corner C retreats to C ′ as shown in FIG. The arc AC passing through C'with the center at does not interfere with the sheet (1) as shown in FIG. Therefore, the seat (2) can be turned rearward as shown in FIG. 5 by rotating the seat (2) in the direction of arrow B in FIG.

The seat (2) is installed on a rotating mechanism (3) as shown in FIG. The rotation mechanism (3) comprises a base (4) and a rotation base (5) rotatably mounted on the base (4), and a seat portion (2A) of the seat (2). Is installed on the turntable (5). The rotation of the turntable (5) is locked by a lock mechanism (6), and a lock release lever (7) is inserted into the lock mechanism (6). Then, the pressing plate (8) communicates with the lock release lever (7) via the rotation shaft (6B) of the locking claw (6A) of the lock mechanism (6), and the pressing plate (8) turns the rotary base ( 5) Abut the cam plate (9) rotatably mounted on the upper side, and operate the lock release lever (7) in the lock release direction (arrow C in Fig. 6) to release the rotation lock. The pressing plate (8) pushes the cam plate (9) in the direction of arrow D via (6B). Then, it is connected to the cam plate (9) and is supported by the guide (10) extended from the rotary table (5) and the guide (11) extended from the frame (2D) of the seat portion (2A). The operating wire (12) shown in FIG. 6 and FIG. 7 has a rotating shaft (14) supported by a bracket (13) attached to the seat (2A) via a rotating piece (15). Rotate in the direction of arrow E. When the rotary shaft (14) rotates in the direction of arrow E, it is supported by the bracket (13) through the operating piece (16) extended from the rotary shaft (14) and locked in the lock direction by the spring (17A). The lock piece (17) biased by the spring moves in the direction of the arrow in Fig. 7 against the biasing force of the spring (17A) and is supported by the bearing (18) extended from the bracket (13). Locking hole (20A) of locking piece (20) inserted from frame (2E) of side edge (2C) of seat (2A) of seat (2) attached to rotating shaft (19) The lock piece (17) is disengaged from. Then, since the frame (2E) is urged in the direction of arrow 7 in FIG. 7 by the spring (21), the side edge portion (2C) is urged by the urging force of the spring (21) via the frame (2E). As it is flipped up and brought into the state as shown in FIG. 3, the seat (2) can rotate forward and backward without being interfered with by the seat (1). Then, when the seat (2) is turned forward, when the side edge (2C) of the seat (2A) is returned from the flipped state to the normal state, the lock piece (17) is moved to the side again by the biasing force of the spring (17A). The edge (2C) engages with the locking hole (20A) of the locking piece (20) of the frame (2E). In this way, the situation shown in FIG. 5 is obtained.

In the above embodiment, the rotation lock mechanism of the seat (2) and the flip-up mechanism of the side edge portion (2C) are interlocked with each other. You can raise it.

[0009]

[Effect of device]

 Therefore, according to the present invention, the seat shape of the seat is not limited, and the seat can be rotated back and forth while avoiding the interference of obstacles.
